The click is no longer guaranteed
Google's AI Overviews — the AI-generated summaries that now appear at the top of many search results pages — have quietly become the defining variable in B2B search performance. For companies relying on organic search to generate pipeline, the implications are significant and, until now, largely unmeasured at the B2B category level.
This study analysed 50 B2B keywords across software, professional services, and growth-stage company categories, measuring the percentage of searches that result in an organic click. The findings reveal a consistent and material gap between keywords where AI Overviews appear and those where they don't — and they point clearly to which categories of B2B content are most at risk.
84% of B2B keywords now trigger an AI Overview. For definitional and metrics-based queries — the terms your buyers use to understand their category — organic click rates have dropped as low as 31%.
How this study was conducted
This study was conducted using Ahrefs keyword data collected in March 2026. We analysed a curated set of 50 B2B keywords spanning four categories: enterprise software, B2B services, how-to and process queries, and definitional/metrics terms commonly used by growth-stage company buyers.
The primary metric used is organic-only click rate — the percentage of searches for a given keyword that result in a click on an organic (non-paid) result. This is sourced directly from Ahrefs keyword data. SERP feature presence (AI Overview, featured snippet, local pack, sitelinks) was recorded alongside each keyword to enable the comparison reported here.
AI Overviews now dominate the B2B SERP
Of the 50 B2B keywords in this study, 42 — or 84% — trigger an AI Overview in Google search. This is a striking figure, and significantly higher than many search practitioners assume. The implication is that for most B2B keyword categories, the AI Overview is now the default SERP experience, not an exception.
The categories with the highest AI Overview penetration were enterprise software (9 out of 10 keywords), B2B metrics and definitional terms (8 out of 9), and how-to queries (8 out of 10). The category with the lowest penetration was B2B services with strong local intent — where the local pack frequently displaces the AI Overview as the dominant non-organic SERP feature.

The central finding of this study is the organic click-rate gap between keywords where an AI Overview appears and keywords where it does not. Across our full dataset, keywords with an AI Overview present show an average organic click rate of 50.6% — meaning roughly half of all searches for those terms do not result in an organic click.
By contrast, keywords without an AI Overview (and without other organic-suppressing features like a local pack) show an average organic click rate of 60.7%. That 10 percentage point gap is material. On a keyword with 10,000 monthly searches, the difference between 50.6% and 60.7% organic CTR represents approximately 1,000 additional clicks per month — clicks that are currently being absorbed by the AI Overview, by paid results, or lost to zero-click behaviour.
The distribution of click rates within the AI Overview group is wide, however. Several keywords — primarily how-to queries — retain organic click rates above 65% even when an AI Overview is present. This suggests that query intent plays a significant moderating role: searches where the user is trying to do something still generate organic clicks at high rates, while searches where the user is trying to know something are more likely to be satisfied by the AI Overview itself.
The hit is not uniform — category matters significantly
Disaggregating the data by keyword category reveals a more nuanced picture than the headline averages suggest. The average 10 percentage point gap between AI-Overview and non-AI-Overview keywords obscures meaningful variation across different types of B2B content.
How-to and process queries are the most resilient category, averaging a 63% organic click rate even where AI Overviews appear. This aligns with intuition: a searcher asking 'how do I build links?' or 'how do I improve my SEO?' is seeking a process to follow — they need detail that a brief AI summary cannot fully satisfy.
The steepest decline is in the definitional and metrics category — the terms B2B buyers and operators use to understand their market and function. Keywords like 'churn rate', 'annual recurring revenue', and 'customer acquisition cost' see organic click rates as low as 31–35%. For these terms, the AI Overview is simply providing the answer, and users have little reason to click through.

The table below shows the individual keywords in our study with the lowest organic click rates — the terms where AI Overviews have most significantly compressed the addressable organic audience.
How-to and process queries remain resilient
Not all categories of B2B content are equally exposed. The data points clearly to one category that maintains strong organic click rates even in the presence of AI Overviews: how-to and process-oriented queries.
The pattern here is consistent: queries framed as 'how to' or that seek a comparative recommendation ('best CRM for…') retain significantly higher organic click rates. The AI Overview cannot fully satisfy a user who wants step-by-step guidance, nuanced comparison, or detailed process walkthrough.
One notable data point: 'what is technical SEO' — a definitional query with a featured snippet rather than an AI Overview — showed a 76% organic click rate, the highest in the dataset. This suggests that the traditional featured snippet may actually direct rather than divert organic traffic, in contrast to the AI Overview's clear suppression effect.
What this means for B2B content strategy
The data in this study has direct implications for how B2B companies — particularly those in software, professional services, and growth categories — should allocate their SEO and content investment going forward.
Audit your keyword portfolio for AI Overview exposure. If your content strategy is anchored in definitional content — 'what is X', category overview posts, metric explainers — you may be targeting keywords where organic CTR has fallen below 40%. These pages may continue to generate impressions without generating traffic or pipeline. Understanding your exposure is the first step.
Shift investment toward process and how-to content. The data is unambiguous: how-to queries retain significantly higher organic click rates even in the presence of AI Overviews. B2B companies that orient their content around helping buyers do things — rather than simply defining or explaining them — are better insulated from AI Overview suppression.
Rethink definitional content as brand and citation asset, not traffic asset. Educational content targeting B2B metrics and definitions still has a role: building brand credibility, generating backlinks, and appearing in AI Overviews as a cited source. But expecting it to drive meaningful organic click traffic in 2026 is increasingly optimistic. Re-categorise this content by its actual job.
Track impressions alongside clicks. The AI Overview era requires a more nuanced view of SERP performance. A page generating 50,000 impressions per month and 20,000 clicks is performing very differently to a page generating 50,000 impressions and 15,000 clicks — and the difference may be explained entirely by AI Overview presence. Monitoring both metrics at keyword level is now essential.
Consider the B2B comparison and evaluation keyword tier. Our data shows that 'best X for Y' and comparative queries retain stronger organic click rates than their definitional counterparts. As AI Overviews become more prevalent, the evaluation stage of the buyer journey — where specificity and comparison matter — may increasingly become the most valuable organic real estate for B2B brands.
