Google AI Overview Optimisation for SaaS: The Complete Guide

If you still think Google AI Overview is a minor SERP feature you can ignore until your next content refresh, I have some bad news and some better news. The game already shifted. Most SaaS founders are late.

Here is where the panic starts. Seer Interactive’s September 2025 study found that AIO-cited brands get 35% more organic clicks and 91% more paid clicks than brands left out of the answer. The inverse is uglier. Non-cited brands are bleeding up to 61% of click-through rate on queries where an AIO now sits above the ten blue links. That is not a ranking problem. That is a pipeline problem. Your demo requests do not care how many positions you moved.

I have spent the last two years building Emgi around this exact shift. In the time we have been working, we have worked with over thirty SaaS brands, most of them between one million and fifty million ARR, and we have watched AIO move from experimental novelty to the default buyer experience on a rising share of commercial queries. I am not going to regurgitate Google’s developer docs. You have read those. This article is the playbook we actually run, with two live case studies, original research numbers we are about to publish, and my honest take on where Google takes AIO in the next eighteen months.

One caveat before we start. Most of the AIO guides already ranking on page one (Finch, 20North, Reusser, the usual suspects) push some version of “write helpful content, add structured data, hope for the best.” That advice is not wrong. It is just incomplete in a way that is costing SaaS teams money. What actually moves AIO inclusion in 2026 is authority density and distribution, not one more blog post with a FAQ schema block. I will show you the data.

What Google AI Overview actually is (and why SaaS teams still get it wrong)

Google AI Overview is the generative answer panel that now appears above the classic ten blue links on a substantial share of SaaS-adjacent queries. It is powered by Gemini, draws from a rotating citation pool, and typically names three to seven sources per answer. Its job is to end the search without sending a click. We are living in the zero-click world. According to Search Engine Land (2025), roughly 75% of AIO citations come from the top twelve organic results. That is the part every guide quotes.

The part nobody quotes is the other 25%. A quarter of AIO citations come from sources that were not even on page one for the query. Frame that properly. The 25% of clicks that still make it through AIO is not a loss, it is a huge opportunity. It is a smaller, higher-intent traffic share, because the users who still click after reading the answer box are the ones actively shortlisting. That is the crack in the door for smaller SaaS brands, and it is where most of the wins I care about happen.

Proof of concept. We ran a UK e-commerce experiment on a brand new exact match domain in late 2025. Zero to seven thousand impressions in two months. More interesting than the impression count: for a stretch of that run, we were the only company under DR 70 appearing on direct commercial-intent prompts with 1,000+ monthly search volume. That is what the 25% opportunity looks like in practice. Authority plus semantic depth, not age plus DR.

Here is where SaaS teams keep getting it wrong. They treat AIO as a classic ranking game with a weird new garnish. It is not. AIO has its own logic, its own volatility, and its own citation pool. Being the top organic result on a query does not mean you get cited. Being cited does not mean you get clicks. The two surfaces overlap, they do not match. I know founders who rank position one on their money keyword, watch the AIO box cite three competitors above them, and still insist their SEO is working because Search Console says “position one.” It is not working. The answer box ate the click.

The three things that make AIO different

First, AIO is extractive. It pulls sentences and data points directly from cited pages. If your content is not structured for extraction (clear question-led headings, 40 to 60 word answer blocks, tables, stat-first paragraphs), Gemini cannot lift it cleanly. Unstructured content gets skipped in favour of structured alternatives, even when the unstructured piece is higher quality.

Second, AIO is entity-led. Google is not matching strings, it is matching your brand to a topical entity graph. If Gartner, G2, Capterra, TrustRadius and Software Reviews all agree you are a “therapy practice management” vendor, you become eligible for AIO inclusion on therapy practice management queries. If your vertical entity signal is thin, you are not even in the pool.

Third, AIO is volatile. Much more volatile than traditional Google search. The citation pool flips week to week on the same query. A page that was cited in March can vanish in April. Semrush’s 2025 AIO tracking found most queries swap at least one citation source per month. Classic rankings feel stable by comparison. AI search today is not a stable ranking surface, it is a shifting citation surface, and any SaaS team treating it like traditional SEO is going to be whiplashed.

My prediction on this. I expect this to stabilise over the coming years and become more algorithmic, continuing to prioritise authority brands, because that is one of the only ways to distinguish which companies are genuinely authoritative and which are not. The volatility is the symptom of a young system. The destination is an authority-weighted, more predictable citation graph. Which is good news if you are building authority now, and very bad news if you are waiting for the dust to settle.

If you measure AIO success with weekly position tracking, you are going to drive yourself mad. Measure citation rate across a cohort of prompts, monthly, and look at the trend, not the shot.

Why SaaS gets hit harder by AIO than almost any other category

B2B SaaS buyers are exactly the audience AIO was built for. They ask long, specific, commercial questions (“best practice management software for physiotherapists under 20 staff”), they want comparative answers (“Cliniko vs Halaxy vs Power Diary”), and they read before they click. This is the worst possible audience for a website that depends on SERP clicks to drive demo requests. The answer box was designed for them.

There is a second reason SaaS feels the pain harder than most. SaaS buying journeys involve multiple comparison points before a demo. “Best CRM for mid-market B2B.” “HubSpot alternatives for teams under fifty.” “Pipedrive vs Close vs Salesloft.” Every one of those is a natural AIO query, and every one of them happens before your sales team ever gets a chance to speak. When AIO filters the shortlist, if you are not in the shortlist, your sales team does not get the call.

The real battleground is middle-funnel and bottom-funnel. Brand-awareness queries are fine to lose to AIO because they were never going to convert directly. But losing “X vs Y” queries to AIO is losing the demo. That is where buyer shortlisting happens, and that is where invisibility costs real revenue.

What the Seer 35/91 numbers actually mean

The headline Seer number everyone is quoting (35% more organic clicks, 91% more paid) is not about AIO being good or bad for you. It is about the divergence between cited brands and invisible ones. If you are cited, AIO acts like an endorsement and lifts both organic and paid performance. If you are not cited, the traffic goes to whoever is. There is no neutral outcome. You win the citation or your competitor wins it.

That framing changes the conversation with founders. It is no longer “should we worry about AIO?” It is “if we do not win citation share in the next two quarters, what does our pipeline look like this time next year?”

The biggest AIO ranking signal is being everywhere

Here is the part I care about most. If you ask me what moves AIO rankings for SaaS brands in 2026, my answer is not “schema.” It is not “helpful content.” It is not “llms.txt.” It is authority, brand mentions, reviews, Reddit threads, directory listings, third-party editorial, expert quotes and podcast appearances. All of it, in volume, across the places your buyers actually read.

This is exactly why we prioritise Search Everywhere Optimisation as our approach at Emgi. The job is not to rank a page. The job is to saturate the entity graph for your category so that Gemini, ChatGPT, Claude, and Perplexity all converge on your brand as a default answer. One DR 85 backlink does not win that. Thirty vertical placements, fifteen directory listings, a couple of Reddit threads and a dozen expert quotes does.

Semrush’s June 2025 research pegged Reddit at roughly 40% of AI citation share across tested queries. That number is slightly off for Google AIO specifically (ChatGPT leans on Reddit harder than Gemini does), but the directional point holds. AI systems reward corroboration across independent sources, and Reddit is one of the cheapest ways to get corroborated by real humans talking about your product.

What this means for your link-building budget

If you are allocating your SEO budget on a “chase DR 70+ placements” rule, you are running an outdated playbook. The real priority is niche-relevant placements, even at lower DR. Relevance compounds. Raw authority, on a site that has nothing to do with your category, plateaus fast. Average SaaS link cost sits around $400 to $600 per placement in 2025 (Ahrefs link cost data, 2025), and the spend works hardest when it lands on publications your buyers already read.

Caveat though, and this is important. If a high-DR link has that same level of topical relevance, it will absolutely cook. Example: getting a link on Close CRM, or a comparable CRM platform, for a sales tech brand is devastating in the best way. High-DR site plus perfect topical relevance is a compounding signal for both Google and the AIO citation pool. That is the placement to fight for. What you should not do is pay premium money for a high-DR placement that sits in the wrong category entirely, because the entity signal is thin and the lift is marginal.

The short version: rebalance your link budget toward vertical density, brand mentions (not just links) and Reddit / G2 / Gartner seeding. The AIO lift comes from the whole picture, not the one trophy link on a site your buyers would never read.

Is AIO traffic loss permanent? (Yes, and that is fine)

The panic question I get most from founders is some version of: “our organic traffic dropped 30% last quarter, the AIO box is showing on half our money keywords, is this permanent?” My honest answer: the traffic loss is permanent. The raw click volumes are not coming back. But that matters less than it feels.

This is why a chunk of the SEO world is quietly re-titling as “brand visibility specialists.” Some people on LinkedIn are calling that framing bullshit, and honestly some of the people using it are bullshitters. But I actually like the phrase. It is accurate. The game now is visibility inside the answer surface, not traffic volume to a blue link. If you are a real operator, that reframe is not marketing spin. It is the job description.

Here is the core point. For real businesses, the game was never about traffic. It was always about revenue. SEO just happened to provide low-cost traffic on the way to revenue. Now SEO is not providing that low-cost traffic as easily. But what it is still doing, and doing better than any other channel, is making you discoverable for the high-intent queries where the valuable traffic sits. The click volume is smaller. The clicks that make it through are warmer.

Compare that to paid. Paid ad costs always rise. Auctions get more competitive, CPCs climb, and paid becomes less efficient over time. Authority-driven SEO does the opposite. It becomes more efficient over time because you compound the authority you already built. The AIO era makes that asymmetry sharper, not smaller. The teams who keep building authority are the ones with a durable cost curve.

Here is how the shift actually happens in practice. You take your top twenty money queries. You check which ones now trigger AIO (use Semrush or SE Ranking’s AIO tracker, both launched 2025). For each AIO-triggered query, you identify the three to five brands currently cited. You study what those brands have that you do not. Almost always, it is a combination of comparison content, vertical directory coverage, and on-page structure optimised for extraction. You close those gaps, one query at a time, starting with the highest commercial value.

Three months in, you will start seeing citation capture on the easier queries. Six months in, you will have rebuilt a different shape of traffic. Lower total clicks, higher qualified clicks, better demo conversion. That is what winning AIO actually looks like for a SaaS brand in 2026. Not a return to 2023 click volumes. A different, better-converting traffic mix, on a cost curve that gets cheaper over time rather than more expensive.

Case study: the allied health campaign that took over practice management queries

Let me show you what this looks like with a real client. Names masked because the work is ongoing.

We started working with an allied health SaaS client in mid-2025. Product covers therapy practice management, appointment automation, clinical notes and an AI scribe feature. Category is crowded. Competition includes Cliniko, Halaxy, Power Diary, SimplePractice, Jane App, and a long tail of region-specific EMR systems. Client had decent organic presence on some brand terms, effectively zero AIO appearance on commercial queries, and a growing anxiety about AI search eating their top-funnel.

We built the anchor text strategy around the real buyer queries: appointment reminders, practice management, clinical notes and AI scribes, plus a vertical education layer. Those are the terms clinic owners and therapists actually type when they are shortlisting. Five anchor clusters in total:

• Appointment reminders. Variants included “automated appointment reminders”, “SMS appointment reminder”, “patient reminder software”, “automated reminders for appointments” and “appointment reminder software for clinics.” High commercial intent, buyers actively comparing.
• Practice management. Variants included “therapy practice management software”, “clinic management software”, “cloud based clinic management software”, “patient management software” and “CRM for clinics.” Core category terms.
• Clinical notes. Variants included “clinical notes software”, “progress note software” and “clinical notes AI app for healthcare professionals.” Middle-funnel, high comparison intent.
• AI scribe category. Variants included “AI scribe”, “AI medical scribe for all clinicians”, “AI scribe for clinicians” and “AI note takers for therapists.” Emerging category, rapidly AIO-triggering.
• Vertical education. Variants like “allied health practice management”, “allied health practice management book”, “allied health business guide.” Top-funnel, brand-building, authority-seeding.

The play was vertical authority, not raw DR. We built links from a mix of allied health publications, clinic-adjacent SaaS blogs, and practice-owner resource sites. DR range across placements was intentionally wide (anything from DR 35 to DR 70+), because the signal Google and Gemini are reading is topical density, not single-link authority.

What happened next was textbook Search Everywhere Optimisation. Within four to five months, the client was surfacing in AIO boxes on the appointment reminder cluster, practice management cluster and AI scribe cluster. Not position one on every query, but cited as one of three to five named sources in the answer. Demo requests from organic grew materially, and the shape of the traffic changed. Lower total volume on the brand’s money keywords (because AIO was answering the question), higher conversion per visitor (because the AIO citation acted as a pre-qualifier).

The insight: vertical authority density, not domain-level DR, tips AIO inclusion in clinical SaaS categories. Google trusts clustered topical citations over generic trophy links.

The shorter point for this article: the anchor focus on appointment reminders, practice management, clinical notes, AI scribes and vertical education is what moved AIO. Not a single money-keyword trophy placement.

What this case study is not

It is not a claim that anyone can replicate this inside three months. It took a sustained build, a clear anchor architecture, and a client willing to fund vertical link acquisition rather than chase trophy domains. It is not a claim that AIO appearance equals revenue growth. That conversion leg is product-led, not SEO-led. What SEO did was put the brand in the shortlist. The product closed the rest.

The UK e-com experiment: AIO in two months on an exact-match domain

I flagged this at the top. Worth unpacking the mechanics here, because it is the clearest single data point I have on how fast authority-led work can tip AIO inclusion. We ran an internal SEO experiment through the back end of 2025 on a new exact-match domain in a UK e-com niche I cannot name. The site was born-yesterday new. Zero backlinks at launch, zero Google history, zero brand presence.

We hit it with our standard Search Everywhere Optimisation playbook: semantic-depth content on the core buying questions, targeted link building on the keywords that started to move in week three, and deliberate brand-mention seeding on two Reddit threads and one Substack piece. Nothing exotic. Nothing black-hat. Same playbook we run on Emgi client engagements, scaled down for a single-niche experiment.

Why does this matter for SaaS readers? Because it is proof that AIO is not gated behind five years of domain age or DR 80 scores. Quality plus semantic depth plus targeted link building tips inclusion faster than the SEO old guard wants to admit. That said, I want to be honest: e-com and SaaS are not identical. E-com buying queries often have simpler intent than SaaS comparison queries. The experiment is a directional proof, not a replicable recipe for every category. But the principle (semantic quality plus distribution beats raw domain age) holds across both.

Emgi’s AIO scoring framework (the high-level reveal)

We score every SaaS brand we audit against a twelve-point AIO readiness grid. I am not going to publish the full scoring sheet here because it is how we diagnose client work, and we refine it quarterly. But I will share enough for you to understand that this is real methodology, not a sales gate. The whole system is weighted toward authority, with distribution as the strongest single inclusion signal we can measure. Everything else is supporting evidence.

The framework splits into four areas with three signals each. Here is the structure.

The scoring itself runs each signal on a zero-to-five scale, then weights them by category sensitivity. Regulated verticals (healthcare, finance, legal) weight entity and citation density harder. Horizontal B2B categories weight distribution and on-page extraction harder. Total score lands between zero and sixty, which we translate to a readiness band (Invisible, Emerging, Competitive, Dominant).

Most of the SaaS brands we audit at first contact sit in the “Invisible” or “Emerging” bands. Even some brands with $10M ARR and strong organic rankings sit Invisible, because ranking on classic organic and being cited in AIO are two different scoring games. I brief clients using our AI visibility audit so they are doing the right things on their side, and we can stack on top with authority work. The on-site work and the off-site authority work compound when they are aimed at the same entity graph. When they are not, the audit shows you why.

If you want us to run this against your brand, book a strategy call. If you want to build your own version, the four-area structure above is the scaffold. Steal it.

CRM and Directory Research

One last data tease before I get to my predictions. We ran a full CRM and directory visibility study across the CRM category, and the correlation findings relevant to this article are too important to hold back.

The counter-intuitive finding is the first one. If Google AIO and ChatGPT correlate at 0.94 on CRM visibility, the “GEO is just SEO” argument has a point at the macro level. Authority still wins. But (and this matters) the smaller brands winning query-level citations are almost always the ones with original data and semantic depth, even when their domain authority is low. Authority wins macro. Original data opens the door.

Apollo.io is the case that breaks the scale argument. Nineteen directories, 24,730 reviews, zero ChatGPT citations on CRM queries. Why? Category positioning mismatch. Apollo is sales engagement, not CRM, and topical relevance overrides raw volume. The lesson: directory density compounds only when the categorisation is correct.

Matt’s prediction: where AIO goes next (the honest take)

This is my opinion section. You can disagree, and plenty of smart people in the industry will. Here is how I think the next eighteen months play out.

Google will dominate AI search eventually. I know that runs against the “ChatGPT ate search” narrative, but look at the fundamentals. Google has controlled search like a monopoly for the better part of two decades. They own the distribution (Chrome, Android, the Google.com habit), the data (every query, every click, every dwell since 1998), and the infrastructure. Gemini is getting genuinely good. Google AI Mode is iterating fast. Culturally we still say “Google it” not “ChatGPT it” (although that is becoming more common, I admit). Defaults matter, and Google owns the default.

Anthropic’s Claude is a serious competitor, and that pulls Google further into the race. I say this slightly nervously because a lot of SEO people are still in the “OpenAI versus Google” framing. It is not that anymore. Claude is arguably already stronger than ChatGPT for enterprise use cases, and enterprise is where the revenue sits. A three-way fight (Google, OpenAI, Anthropic) is harder for any one player to dominate, which means Google will push AIO harder into the main surface to defend their moat.

Paid advertising will land in AI surfaces next. This one is not a prediction so much as an inevitability. We live in a capitalist society after all. The moment Google figures out the right ad unit for AIO (sponsored citations, promoted answer slots, something we have not seen yet), it will ship. The Seer stat showing 91% paid-click lift for AIO-cited brands is already a hint at what is coming. My working guess is “sponsored citation” slots by late 2026 or early 2027, which will further compress organic AIO real estate and push the SaaS teams who did not build entity authority early into paid.

What this means for your 2026 plan. Build authority now, while it is still relatively cheap. Vertical link building, directory density, Reddit presence, expert quotes, comparison corpus coverage. All of it, distributed across the publishers and surfaces your buyers already read. The teams that win AIO in 2026 are the ones who treat Search Everywhere Optimisation as a budget line, not a bonus round. The teams that lose are still debating whether to write an llms.txt file.
