What are Link Building Metrics?

Link building metrics are quantitative indicators used to assess the quality and effectiveness of backlinks in search engine optimization (SEO). The Link building metrics help evaluate link strength, authority, relevance, diversity and impact on organic rankings.

Link building metrics play a critical role in optimizing search visibility as the metrics help marketers determine the value and credibility of backlinks. Domain authority, trust flow, citation flow and anchor text relevance are key metrics that reflect the strength of links. A high-quality backlink profile significantly improves a website’s ranking potential, search engine trust and organic traffic. Assessing metrics such as link velocity and backlink diversity ensures that link-building efforts maintain a natural growth pattern, reducing the risk of penalties.

What are the Types of Link Building metrics?

The types of link building metrics include Domain Authority, Domain Rating, Authority Score, Page Authority, referring domains, backlinks, anchor text, dofollow vs. nofollow links, linking site relevance, link placement, number of links, new backlinks, PageRank, linking page relevance, link quality, spam score, linking domain strength, traffic from links, trust flow, citation flow, link velocity, link equity, and link building ROI. These metrics help assess link quality, authority, relevance, and impact on SEO performance.

Following image shows some of the link building metrics.

Following is the detail of each type of link building metric:

Domain Authority (DA)

Domain Authority (DA) is a metric developed by Moz that predicts a website’s ability to rank in search engine results based on factors such as backlink profile, quality and relevance. Domain Authority works as a link-building metric by evaluating the strength of a website’s backlinks which helps estimate its ranking potential. The DA score ranges from 1 to 100 with higher scores indicating a more authoritative website that is likely to perform well in search engines. Tools like Moz calculate DA using multiple factors including the number of referring domains, quality of backlinks and link diversity. A high DA suggests that a domain has earned quality backlinks from reputable sources, contributing positively to its SEO efforts. Link-building campaigns focused on obtaining links from high-DA domains help enhance a target website’s authority and improve its search visibility. 

Domain Rating (DR)

Domain Rating (DR) is a metric developed by Ahrefs that measures the overall strength and authority of a website’s backlink profile on a scale from 0 to 100. Domain Rating works as a link-building metric by evaluating the quality and quantity of backlinks pointing to a website which helps determine its potential ranking power. A higher DR indicates a strong backlink profile with links from reputable and authoritative domains, suggesting greater influence in search engines. Tools like Ahrefs use DR to assess how well a domain’s backlinks are contributing to its authority, providing a benchmark for SEO practitioners to compare with competitors. DR is calculated by considering the number of unique referring domains and the quality of those domains which gives a more accurate representation of link value. Acquiring backlinks from domains with high DR significantly boosts the linked website’s authority, enhancing its search visibility. 

Authority Score

Authority Score is a metric developed by Semrush that measures the quality and strength of a website’s backlink profile, content and SEO performance. Authority Score works as a link-building metric by providing a comprehensive evaluation of a domain’s authority based on factors like referring domains, backlink quality and organic search visibility. A higher Authority Score indicates that a website has a strong link profile and is more likely to rank well in search engine results. SEO tools like Semrush use Authority Score to help marketers gauge the value of potential link opportunities, focusing on acquiring links from high-authority sites. The score with higher values reflects greater credibility and influence in a given industry. Evaluating Authority Score helps SEO practitioners prioritize outreach efforts as backlinks from domains with high scores significantly enhance a target website’s authority. Monitoring changes in Authority Score over time allows marketers to assess the impact of their link-building and content strategies on domain strength. 

Page Authority (PA)

Page Authority (PA) is a metric developed by Moz that predicts how well a specific webpage is likely to rank in search engine results based on its backlink profile and other SEO factors. Page Authority works as a link-building metric by evaluating the strength of individual web pages rather than entire domains, helping SEO practitioners prioritize which pages need better link acquisition. The PA score ranges from 1 to 100 with higher scores indicating greater ranking potential driven by factors such as the quality and quantity of backlinks. A high PA score suggests that the page is well-linked to and has substantial authority which improves its chances of ranking prominently. Link-building efforts aimed at increasing PA involve acquiring high-quality backlinks from authoritative and relevant sources. Evaluating changes in Page Authority over time helps measure the effectiveness of link-building campaigns and shows how well the page is gaining authority. 

Referring Domains

Referring domains are unique websites that contain at least one backlink pointing to a target website. Referring domains work as a link-building metric by measuring the number of unique sources that link to a website, providing an indicator of its popularity and authority. The more referring domains a website has the more diverse and credible its backlink profile tends to be which positively influences its search rankings. A high number of referring domains is generally beneficial when the domains are authoritative and relevant to the target site’s niche. Evaluating referring domains also involves analyzing domain authority and content relevance to ensure that the links are adding genuine value to the site. Diversifying the sources of backlinks helps create a natural link profile which reduces the risk of penalties from search engines for manipulative link-building practices. 

Backlinks

Backlinks are hyperlinks from one website to another that act as signals of credibility, relevance and authority to search engines. Backlinks work as link-building metrics by evaluating the quantity, quality and context of links pointing to a website which collectively influence its authority and ranking potential. The number of backlinks reflects the popularity of the site, determined by factors like domain authority and relevance of the linking page. High-quality backlinks from authoritative domains significantly enhance a website’s domain authority and visibility in search results. Backlinks also help search engines discover new content as they act like pathways that guide search crawlers across the web. Analyzing the diversity of referring domains provides insights into the breadth of link-building efforts which contributes to a natural and robust backlink profile. 

Anchor Text

Anchor text is the clickable text in a hyperlink that provides context about the linked page’s content. Anchor text works as a link-building metric by indicating the relevance and intent of the link, helping search engines understand the content of the linked page.  Anchor Text Optimization is effective for link building strategies as it ensures that links provide meaningful value and contribute to the targeted keywords’ rankings. By using varied, natural anchor text, you avoid penalties from search engines while enhancing semantic relevance and link credibility. A variety of anchor texts such as branded, keyword-rich, generic and URL-based contribute to a natural link profile and enhance link-building efforts. Overuse of keyword-rich anchor text leads to penalties from search engines as it appears manipulative. Analyzing anchor text distribution helps ensure a balance between different types of anchor text which supports a diverse and healthy backlink profile. Properly optimized anchor text improves a website’s ranking for targeted keywords as it signals relevance and topic authority to search engines.

Dofollow vs. Nofollow Links

Dofollow links pass SEO value and authority from the linking site to the linked site, while nofollow links do not pass SEO value and instruct search engines not to follow the link. Dofollow vs. nofollow links work as link-building metrics by assessing the type of backlinks a website has which affects its authority and ranking potential. Dofollow vs nofollow links are critical considerations in link building strategies as each type serves different purposes in SEO. 

Dofollow links build domain authority as they allow link equity to flow from the referring site to the target site. Tools like Ahrefs, Moz and Semrush help SEO practitioners track the proportion of dofollow and nofollow links to evaluate the quality and SEO impact of a backlink profile. A healthy backlink profile typically includes a balanced mix of dofollow and nofollow links as an all-dofollow profile appears unnatural to search engines. Nofollow links do not pass direct link equity but still contribute to referral traffic and play a role in brand visibility and diversity of link sources. 

Relevance of the Linking Site

The relevance of the linking site refers to how closely related the content and niche of the website providing a backlink are to the target website it links to. The relevance of the linking site works as a link-building metric by evaluating whether the backlink originates from a site that shares a similar topic or industry which enhances link value. Search engines prioritize backlinks from contextually relevant sources as they indicate a natural and authoritative connection between the linking and linked content. SEO tools like Ahrefs and Semrush analyze the topical relevance of linking domains to assess the quality and impact of backlinks. A backlink from a site within the same niche contributes positively to the credibility of the linked website, improving its search engine rankings. Links from unrelated or irrelevant sites carry the same value and even be flagged as spammy or manipulative. 

Link Placement

Link placement refers to the specific location on a webpage where a backlink is positioned, such as in the content body, sidebar or footer. Link placement works as a link-building metric by assessing the context in which a backlink appears which influences its perceived value by search engines. Backlinks placed within the main content of a page, known as contextual links are considered more valuable because they are more relevant and integrated into the surrounding text. SEO tools like Ahrefs and Moz help analyze link placement to determine the effectiveness of acquired backlinks based on their position on the linking page. Links in high-visibility areas like the content body are more likely to be clicked by users, providing greater value for referral traffic and SEO. Links in footers or sidebars carry less weight as search engines often attribute higher authority to links embedded within meaningful content. Evaluating link placement allows SEO practitioners to focus on acquiring links in prominent, relevant positions that enhance user engagement and link equity. 

Number of Links

The number of links refers to the total count of backlinks pointing to a website from various external sources, regardless of their quality. The number of links works as a link-building metric by providing an overview of a website’s backlink profile, reflecting its popularity across the web. A high number of backlinks suggest that a site has considerable reach and influence within its niche. SEO tools like Ahrefs, Moz and Semrush track the number of backlinks, enabling marketers to understand the breadth of their link-building campaigns. Quantity is important and must be evaluated alongside link quality to avoid the risk of accumulating spammy or low-value links. Tracking the number of links also helps identify link acquisition trends and provides insights into the effectiveness of content marketing and outreach strategies. A sudden increase in backlinks is indicative of viral content or successful PR efforts while a decline suggests lost links or the need for more proactive link-building. 

Number of New Backlinks

The number of new backlinks refers to the count of fresh inbound links acquired by a website over a specified period. The number of new backlinks works as a link-building metric by assessing the rate at which a website is gaining links which is an indicator of its popularity and content value. Tools like Ahrefs, Moz and Semrush track new backlinks to provide insights into link acquisition trends over time. A consistent increase in new backlinks indicates successful outreach or content marketing efforts that are resonating with the audience. Evaluating the number of new backlinks helps marketers understand the effectiveness of recent link-building campaigns and their impact on site authority. The rate of backlink acquisition also known as link velocity is crucial because a natural link growth pattern positively affects search engine rankings. A sudden spike in new backlinks indicates manipulative link-building tactics which lead to search engine penalties if not managed properly. 

PageRank

PageRank is an algorithm developed by Google that evaluates the importance and authority of web pages based on the quality and quantity of backlinks pointing to them. PageRank works as a link-building metric by analyzing the backlink profile of a page to determine its influence within the web ecosystem and assigns a score to web pages, reflecting their authority based on the number and quality of incoming links. Links from high-authority pages pass more PageRank, increasing the authority of the linked page and improving its search engine ranking potential. The PageRank algorithm uses a combination of link quantity and link quality with a greater emphasis on high-quality backlinks from reputable domains. PageRank also considers the link distribution within a site with internal linking playing a role in how authority flows between pages. Tools that emulate PageRank calculations like Ahrefs’ URL Rating help SEO practitioners understand the link equity passed to specific pages. 

Linking Page Relevance

Linking page relevance refers to the degree to which the content of a page providing a backlink is contextually related to the content of the target page it links to. Linking page relevance works as a link-building metric by evaluating how well the subject matter of the linking page aligns with the topic of the target page. When backlinks come from relevant pages within the same industry or niche, they pass more contextually valuable link equity which contributes positively to the target page’s SEO. Tools like Ahrefs and Semrush assess linking page relevance by analyzing content context, keywords and topical relationships. A high relevance score indicates that the backlink is likely to enhance the target site’s authority in its particular niche. Linking page relevance also helps search engines understand the topical consistency of the website’s backlinks which supports content trustworthiness. Backlinks from pages with irrelevant content appear unnatural and add little value, potentially affecting the effectiveness of link-building campaigns.

Link Quality

Link quality refers to the value and credibility of a backlink based on the authority, relevance and trustworthiness of the referring domain. Link quality works as a link-building metric by assessing the characteristics of backlinks to determine their impact on a website’s authority and ranking potential. Metrics like Trust Flow, Domain Authority (DA) and Citation Flow help evaluate whether the linking domain is reputable and authoritative. A high-quality link comes from a well-regarded, contextually relevant website that adds value to the linked content. Tools like Ahrefs, Moz and Semrush analyze link quality by considering factors such as link placement, anchor text and the overall authority of the referring site. Evaluating link quality ensures that SEO practitioners focus on acquiring valuable backlinks that contribute positively to search rankings. Low-quality links such as those from spammy or irrelevant sites harm a site’s SEO performance and risk penalties. 

Spam Score

Spam Score is a metric developed by Moz that estimates the likelihood of a website being penalized by search engines based on the presence of potentially spammy indicators. Spam Score works as a link-building metric by evaluating the quality of a website’s backlink profile, identifying links that may be low-quality or harmful and assessing various indicators such as low domain authority, high ratio of follow-to-nofollow links and link patterns commonly associated with spam. A high Spam Score suggest that a website has accumulated backlinks from potentially harmful sources which negatively affect its search engine rankings. Tools like Moz provide Spam Scores for individual domains, helping SEO practitioners identify risky linking domains within their backlink profiles. Analyzing Spam Scores helps ensure that link-building efforts are focused on acquiring high-quality links rather than accumulating low-quality, spam-like links. Identifying and disavowing links from high-Spam Score domains helps mitigate the risk of search engine penalties. 

Linking Domain Strength

Linking domain strength refers to the authority and credibility of a domain that links to another website, influencing the value of the backlink. Linking domain strength works as a link-building metric by assessing the quality of the domains from which backlinks are acquired. Metrics like Domain Authority (DA) from Moz or Domain Rating (DR) from Ahrefs help quantify the authority of these domains with higher values indicating greater strength. A backlink from a strong linking domain passes more link equity by positively impacting the target website’s ranking potential. Tools like Majestic and Semrush help analyze linking domain strength by evaluating attributes such as the number of high-quality referring domains, Trust Flow and Citation Flow. Evaluating the strength of linking domains helps SEO practitioners identify valuable link-building opportunities that contribute significantly to authority. A strong linking domain profile also suggests that a website’s backlinks are from reputable, authoritative sources and enhances credibility. 

Traffic from Links

Traffic from links refers to the visitors who arrive at a website by clicking on hyperlinks from other websites known as referral traffic. Traffic from links works as a link-building metric by evaluating the effectiveness of backlinks in driving targeted visitors to a site and measures the volume of traffic coming through external links which helps assess the value of specific backlinks in terms of user engagement. SEO tools like Google Analytics track referral traffic to identify the referring domains and the pages generating the most traffic. Analyzing these metrics helps determine which backlinks provide the most significant impact on a website’s traffic and visibility. The quality of traffic from links is also evaluated by analyzing metrics like bounce rate, time spent on site and conversion rate. The insights allow marketers to identify high-performing backlinks and prioritize similar link-building opportunities.  

Trust Flow (TF)

Trust Flow (TF) is a metric developed by Majestic that measures the quality and trustworthiness of a website based on the authority of the sites linking to it. Trust Flow works as a link-building metric by analyzing the quality of referring domains and focusing on the credibility and trustworthiness of those sources. TF is calculated by evaluating how closely a website’s backlinks are connected to trusted seed sites which are well-known and authoritative websites. A higher Trust Flow score indicates that a website is linked to credible sources which contribute positively to its perceived authority in search engine algorithms. TF is used alongside Citation Flow (CF) to assess the quality and quantity of backlinks pointing to a site. Comparing Trust Flow to Citation Flow helps determine whether a backlink profile is well-balanced as a high Citation Flow but low Trust Flow may indicate a high number of low-quality links. SEO tools like Majestic provide Trust Flow scores for individual pages and domains, aiding in link-building strategy optimization. 

Citation Flow (CF)

Citation Flow (CF) is a metric developed by Majestic that predicts the influence or authority of a website based on the quantity of backlinks pointing to it. Citation Flow works as a link-building metric by evaluating the volume of backlinks and assigning a score that reflects the potential influence of a site. CF measures the impact of backlinks by assessing the number of unique linking pages with a higher score indicating greater influence. CF is used alongside Trust Flow (TF) which is another Majestic metric to determine the quality and trustworthiness of backlinks. A high Citation Flow score without a proportionate Trust Flow suggests a high quantity of low-quality links indicating potential risks for SEO. Tools like Majestic provide a Citation Flow score for each website which helps SEO practitioners evaluate the strength of their backlink profiles. Analyzing CF helps identify influential linking domains that significantly impact the website’s authority. 

Link Equity (Link Juice)

Link Juice, also known as link equity, measures the value or authority passed from one webpage to another through hyperlinks. When a high-authority page links to another, it transfers a portion of its ranking power, thereby enhancing the linked page’s search engine visibility. Link equity plays a significant role in SEO as it determines how much authority is transferred through internal or external links, directly impacting the linked page’s ranking potential. Effective distribution of link juice within a website can strengthen its overall structure, ensuring that important pages receive adequate link value to rank well. This metric relies heavily on factors such as the linking page’s authority, the relevance of the link, and its position on the page, all of which influence the transfer of link juice and help improve a website’s search engine performance.

Link Velocity

Link velocity refers to the rate at which a website gains or loses backlinks over a specific timeframe. Link velocity works as a link-building metric by evaluating the pace of backlink acquisition to determine whether it appears natural or manipulative to search engines. A steady link velocity indicates a sustainable and organic link-building strategy which positively influences the website’s authority. Tools like Ahrefs and Moz track the growth in the number of backlinks over time, providing insights into the dynamics of a site’s link-building efforts. Rapid spikes or sudden drops in link velocity may raise red flags to search engines which lead to penalties for suspicious link acquisition practices. Monitoring link velocity helps SEO practitioners gauge the health of their backlink profile by identifying trends that could affect search engine ranking. Analyzing link velocity also reveals the impact of specific link-building campaigns and whether they resulted in consistent backlink growth.

Link Building ROI

Link building ROI (Return on Investment) refers to the measure of the financial returns or benefits obtained from link-building activities compared to the costs invested. Link building ROI works as a link-building metric by analyzing the impact of backlinks on website performance metrics like organic traffic, search engine rankings and conversions. Tools like Google Analytics and Semrush help track the increase in referral traffic and organic keyword rankings driven by acquired backlinks. Measuring ROI involves comparing the costs associated with obtaining backlinks such as outreach campaigns or content creation with the value derived from improved visibility and traffic. By assessing key performance indicators (KPIs) such as increased leads or sales, link-building ROI quantifies the effectiveness of link acquisition strategies. Tracking conversions that originate from referral links helps to identify high-value backlinks contributing to tangible business outcomes. Analyzing link-building ROI also helps prioritize high-return link sources, refining strategies for greater efficiency and profitability.

How to Measure Link Building Metrics?

To measure link building metrics, focus on backlink quantity, backlink quality, anchor text distribution, linking root domains, competitor link profile, indexation status, link velocity, and referral traffic. 

Let’s discuss how each metric provides insight into backlink value, growth patterns and SEO impact.

Backlink Quantity

Backlink quantity refers to the total number of backlinks pointing to a website from various sources regardless of quality. Backlink quantity measures link-building metrics by evaluating the volume of backlinks to determine the reach and popularity of a website. A higher backlink count indicates that a site is well-referenced across the web which contributes positively to its perceived authority. SEO tools like Ahrefs, Moz and Semrush provide data on the number of backlinks including unique linking pages to assess the scale of link-building campaigns. While backlink quantity helps to measure reach, it must be evaluated alongside backlink quality to avoid an overemphasis on low-value or spammy links. By analyzing backlink quantity, users track the growth of their link profile over time and ensure consistent progress in link acquisition efforts. A high number of backlinks contribute to increased domain authority, especially when combined with high-quality referring domains. 

Backlink Quality

Backlink quality refers to the value and authority that a backlink provides to the target website, determined by factors such as the credibility of the referring domain, relevance and link attributes. Backlink quality measures link-building metrics by assessing the authority of the referring domains using metrics like Domain Authority (DA) or Domain Rating (DR). Backlink quality considers the contextual relevance of the linking content, ensuring the backlink comes from a related industry or niche. Tools like Moz, Ahrefs and Semrush help analyze the quality of backlinks by checking attributes such as link placement, follow or nofollow status and anchor text relevance. High-quality backlinks typically come from authoritative and trustworthy websites which pass significant link equity to the target site. Analyzing backlink quality also involves evaluating user engagement metrics such as traffic generated from the referring link to determine its actual impact. Links from spammy or low-authority sites are considered low-quality and negatively impact the website’s ranking potential.

Anchor Text Distribution

Anchor text distribution refers to the variety and frequency of words or phrases used in backlinks that point to a website. Anchor text distribution measures link-building metrics by evaluating the diversity and relevance of anchor texts used across a website’s backlink profile. Tools like Ahrefs, Moz and Semrush analyze anchor texts to categorize them into branded, keyword-rich, generic and URL-based types. The analysis helps determine whether anchor text usage is natural and optimized which is crucial for avoiding search engine penalties due to over-optimization. A healthy anchor text distribution includes a balanced mix of branded terms, keywords and natural phrases which ensure a natural link profile. By tracking anchor text patterns, SEO practitioners identify areas where the anchor text is too heavily focused on target keywords indicating potential risks for penalties. The distribution also reveals the effectiveness of link-building campaigns in terms of keyword targeting and brand mention. 

Linking Root Domains

Linking root domains refer to the unique websites that have at least one backlink pointing to a target website regardless of the number of individual links they contain. Linking root domains measure link-building metrics by evaluating the diversity of sources linking to a target website. The greater the number of unique linking root domains, the higher the likelihood that the website is perceived as authoritative by search engines. Tools like Ahrefs and Moz track the total count of linking root domains and provide insights into the breadth of a website’s backlink profile. A high number of linking root domains suggests a diversified and credible backlink profile which positively influences a site’s domain authority. Analyzing linking root domains also reveals the nature and authority of the referring websites which contributes to a better understanding of link quality. Monitoring growth trends in linking root domains helps to assess the effectiveness of link-building campaigns and identify opportunities for outreach to reputable domains. By increasing the number of quality linking root domains, a website boosts its authority, visibility and search engine rankings. 

Competitor Link Profile

Competitor link profile refers to the collection of backlinks that point to a competitor’s website by providing insights into their link-building strategies and SEO strength. Competitor link profile measures link-building metrics by analyzing the quality and quantity of backlinks that competitors have acquired and identifying referring domains, anchor texts and link types to understand the strategies used by competitors to build authority. Tools like Ahrefs, Moz and Semrush provide in-depth analysis of competitor link profiles, highlighting authoritative referring domains that contribute to a competitor’s high search rankings. By studying the metrics, you identify link opportunities such as websites that frequently link to industry-related content. The competitor link profile also helps assess the rate at which competitors acquire new backlinks and provides insights into their link velocity. The data enables the comparison of one’s own link-building efforts with competitors, revealing potential gaps and opportunities. 

Indexation Status

Indexation status refers to whether a webpage is included in a search engine’s index, making it eligible to appear in search results. Indexation status measures link-building metrics by determining whether the pages that contain backlinks are indexed by search engines like Google. If a page with valuable backlinks is indexed, the link equity or value it provides contributes positively to the linked site’s SEO performance. Tools like Google Search Console help track the indexation status of both referring pages and target pages to ensure backlinks are effectively contributing to visibility. Pages that fail to get indexed lead to lost link value, diminishing the impact of the backlinks originating from those pages. Analyzing the indexation status helps assess if link-building efforts are focused on acquiring links from quality sites that get indexed consistently. Indexation monitoring allows SEO practitioners to take corrective action like optimizing referring pages. Ensuring that referring pages are indexed helps link-building campaigns yield effective results by providing actual link value in terms of improved search engine rankings and visibility.

Link Velocity

Link velocity refers to the rate at which a website acquires or loses backlinks over a specific period of time. Link velocity measures link-building metrics by tracking the number of new and lost backlinks to evaluate the pace of link growth. The tool helps assess whether a website’s link acquisition is consistent and organic or irregular which impact its perceived credibility by search engines. By analyzing link velocity, SEO tools determine the effectiveness of link-building strategies and detect potential red flags such as unnatural spikes in backlink acquisition. Tools like Ahrefs or Semrush track link velocity over time to provide insights into the trends of backlink growth. A healthy link velocity indicates a natural progression of backlink acquisition while sudden spikes may trigger search engine penalties. Monitoring the attributes of referring domains in link velocity analysis helps assess the quality of newly acquired backlinks. 

Referral Traffic

Referral traffic refers to visitors who arrive at a website through hyperlinks from other websites rather than through search engines or direct visits. Referral traffic measures link-building metrics by tracking the volume of visitors driven by backlinks from external websites. The tool assesses the source of each referral to determine which backlinks are generating traffic by evaluating the effectiveness of link-building efforts. Tools like Google Analytics help identify referring domains, pages and the specific links responsible for driving referral traffic. By analyzing metrics such as the number of sessions, bounce rate and average session duration, referral traffic insights reveal the quality of the traffic that backlinks are bringing to a site. Referral traffic categorizes backlinks by quality based on the authority of the referring domain and user engagement metrics. Monitoring referral traffic over time allows users to assess trends in link performance and the impact of their link-building strategies.
