Most B2B brands rank for thousands of keywords in Google, but appear in only about 3% of AI-generated answers, according to Walker Sands’ B2B AI Search Visibility Benchmark of 828 enterprise companies. (Disclosure: I’m the director of SEO and GEO at Walker Sands.)

The benchmark analyzed more than 45 million search queries in March across 828 enterprise B2B companies spanning 14 industries. It evaluated domains across four metrics:

• Keyword coverage: The number of keywords for which a company ranks in Google.
• Keywords with AI Overviews: The number of ranking keywords that trigger AI Overviews.
• AI Overview incidence: The percentage of ranking keywords that display AI-generated responses.
• Citation inclusion rate: How often a company’s domain is cited within those AI-generated answers.

Together, these metrics establish a baseline for how often AI Overviews appear and how often B2B brands are cited within them.

A baseline for B2B AI search visibility

The benchmark reveals a significant gap between ranking visibility and AI citation visibility.

• AI Overviews appear in 50% of search results where enterprise B2B brands rank.
• The median enterprise B2B brand is cited in just 3% of relevant AI Overviews.
• 4.6% of enterprise B2B companies aren’t cited in AI Overviews for any of their relevant keywords.

The typical enterprise B2B company ranks organically for about 9,700 search queries, and AI Overviews appear in nearly half of them. Yet across those opportunities, the median brand is cited in just 3% of AI Overviews.

In other words, B2B brands are present in the search results AI Overviews summarize, but they’re largely invisible within the summaries themselves.

While 4.6% represents a small portion of the market, it highlights a critical visibility gap. These companies may still rank well in traditional search results, but some brands are effectively absent from AI Overviews, which have become an influential part of the buyer journey.

In many cases, a lack of citations signals larger issues, such as:

• Limited topical authority.
• Unstructured or inaccessible content.
• A lack of content that directly answers buyers’ questions.

Addressing these gaps is crucial for visibility in AI-driven search experiences.

The narrowing funnel from ranking to citation

The benchmark frames AI search performance as four sequential layers, and the value lost at each step tells the real story.

It starts with keyword coverage, or the number of keywords for which a brand ranks in Google’s top 100 organic results. Here, the leaders look healthy. The median company ranks for about 9,700 keywords, while top-quartile brands rank for more than 37,000.

The next layer, keywords with AI Overviews, narrows the field. These are ranking keywords that trigger an AI Overview. The median company has roughly 4,500 of them, already less than half of its ranking footprint.

The third layer, AI Overview incidence, measures how often AI-generated answers appear across a brand’s relevant searches. The median is 48.8%, meaning AI now intercepts roughly half the queries where these companies compete. Top-quartile brands operate in even more AI-saturated environments, at 61.7%.

The final layer is the one that matters most and where almost everyone falls off a cliff: citation inclusion rate, or how often a brand is cited as a source within an AI Overview. The median is 3.0%. Even the top quartile reaches only 4.5%, while the bottom quartile sits at 1.7%.

Viewed from top to bottom, the funnel is brutal. Tens of thousands of ranking keywords compress into a single-digit share of AI citations. Most of the visibility B2B brands have built through organic search doesn’t carry through to the layer of search that increasingly shapes buyers’ first impressions of a category.

Ranking breadth doesn’t buy you AI citations

The most important takeaway is also the most counterintuitive: Ranking breadth alone doesn’t predict AI citation rates.

The study found that some companies rank for thousands of keywords yet rarely surface in AI-generated answers. The strengths that won traditional SERP real estate — sheer page volume, broad keyword targeting, and domain authority accumulated over the years — don’t automatically translate into becoming the source an AI system chooses to cite.

This is a meaningful break from how most B2B SEO teams are still resourced and measured. If your dashboard tracks ranking keywords and estimated organic traffic, it may be telling a flattering story about a layer of search that’s shrinking in influence while saying nothing about the layer that’s growing.

The benchmark argues that brands consistently cited in AI-generated answers share three characteristics: deep topical authority across related content areas, clear and structured explanations that directly answer buyer questions, and consistent coverage across multiple relevant pages.

The common thread is specificity. Generative systems appear to reward content that resolves a buyer’s question clearly and demonstrates sustained expertise on a topic, rather than content that simply ranks for a query.

That reframes the work. Optimizing for AI citations looks less like chasing keyword volume and more like building genuine, well-structured subject-matter depth.

Some industries are far more exposed than others

AI search visibility isn’t distributed evenly across B2B technology. The industry breakdown reveals sharply different competitive dynamics depending on the category.

Cybersecurity leads on both fronts. AI Overviews appear in a median of 59.9% of cybersecurity-related searches, and cybersecurity brands earn the highest median citation rate in the study at 4.2%. Enterprise software (55.3% AI Overview incidence) and martech (56.3%) also see AI-generated answers in well over half of relevant queries.

At the other end, professional services and distribution and logistics trail in citations, both with a median rate of just 2.1%. Distribution and logistics also have the lowest AI Overview incidence, at 29.6%, meaning buyers in that category encounter AI-generated summaries far less often than in cybersecurity.

These differences create both risks and opportunities. In categories where AI-generated answers are already pervasive, such as cybersecurity, the cost of being invisible is immediate. Buyers are forming impressions inside AI summaries right now.

In categories where citation rates are low and few brands have figured out the new mechanics, there’s a genuine first-mover opportunity. Brands that learn to earn citations before their competitors can shape how an entire category is framed in AI-generated answers, much as early SEO adopters captured outsized shares of organic visibility.

The brands that have gone completely dark

The most striking number in the report is that 4.6% of enterprise B2B companies aren’t cited at all in AI-generated answers for their relevant keywords.

These aren’t fly-by-night operations. They’re companies with $100 million or more in revenue that, in many cases, still rank well in traditional search. They’ve simply become invisible in the AI layer — present in the index, absent from the answer.

Near-zero citation rates can be attributed to deeper structural issues: thin topical authority, content that’s unstructured or difficult for systems to parse, and a lack of material that directly answers the questions buyers are asking.

For a small but meaningful slice of the market, AI search isn’t a place where they’re losing share. It’s a place where they don’t exist.

What this means for B2B search teams

The benchmark provides a baseline, but the strategic implications for SEO, GEO, and marketing teams are already clear.

• Measurement must evolve. Citation inclusion rate is now a distinct KPI from ranking. Teams that can’t see whether their content is being cited in AI-generated answers are flying blind on one of the fastest-growing parts of the funnel. Knowing your own citation rate — and benchmarking it against the 3% median and 4.5% top-quartile benchmarks — is a sensible first step.
• The content mandate shifts from breadth to depth. The drivers all point toward consolidating authority around the topics that matter to buyers, structuring content so machines can interpret it, and answering real questions directly rather than producing volume for volume’s sake.
• The window is open but closing. Generative AI will influence more than 75% of B2B search queries within the next one to two years. If that projection holds, even approximately, the median 3% citation rate isn’t a stable equilibrium. It’s a snapshot of an early, contested market that rewards brands moving now.

The uncomfortable truth is that much of the SEO equity B2B brands have built is being summarized by AI systems that don’t cite the companies that created it. For most enterprise brands, the question is no longer whether they rank. It’s whether they’re in the answer at all.
