Measurement Report · September 2026

We measured 2,061 AI citations across six engines. Vendor websites supplied 5% of them.

There is a comfortable assumption behind most AI visibility work: publish enough good pages on your own domain and the engines will eventually quote them. We tested that assumption against our own category for three weeks, kept every source URL the engines returned, then opened each cited page to check whether we were on it. The assumption did not survive.

This report covers one category — AI visibility and answer-tracking software — measured against one brand we operate. That is a narrow base, and we say so up front rather than in a footnote. What makes it worth publishing is the verification step: we did not infer presence from the answers, we opened the cited pages and read them.

Measured 20 August – 11 September 2026 across ChatGPT, Perplexity, Gemini, Claude, Grok and Google AI Overviews.

What the engines actually cited

Across 23 scans, the six engines returned source URLs resolving to 25 distinct third-party hosts. Grouped by what kind of page they are, the evidence set is not balanced — it is dominated by other people's comparison content.

Third-party citations by source type. Percentages are of the 2,061 third-party citations and exclude the vendor's own domain, which is counted separately below. Rival-owned and engine-owned domains are excluded from the source set.
Source typeHostsCitationsShareWhat these pages are
Roundups & comparisons181,06151.5%"Best X tools", "alternatives to Y" listicles on independent blogs
Community359929.1%Reddit threads, LinkedIn posts, Quora answers
Video128814.0%YouTube, including Shorts
Independent articles31135.5%Single explainers, not listicles

Two of those rows deserve attention because they are where budget rarely goes. A single host, Reddit, was cited 411 times — about twice the most-cited dedicated roundup site, and nearly four times our entire own-domain total. YouTube supplied 288 citations on its own, 14% of the third-party evidence, from one host. Neither is a place most software companies treat as a distribution channel for buying-stage content.

The twelve hosts that carry the category

Top 12 third-party hosts by citation count, 20 August – 11 September 2026. "On the page?" is the result of opening the host's cited pages and reading them in full — not inferred from the answers. "Not read" means our crawler has not yet reached it and is not evidence of absence.

Only one host in the whole set — getairefs.com — was cited by all six engines. It is a blog most people in this category have never heard of, and it outranks every vendor's own domain as a source of evidence about that category's products.

On the five hosts marked "not read". Our crawler had not yet opened them at the time of measurement. That is not the same as being absent from them, and we do not count them as gaps. They represent 218 of the 2,061 citations. The 20 verified-absent hosts account for 1,843 citations, or 89.4% of the third-party evidence set.

The engines do not behave alike

Averaging the six engines together hides the most actionable finding in the dataset. They differ enormously in how much outside material they will pull in.

Breadth of third-party sourcing per engine, measured as how many of the 25 tracked hosts each engine cited at least once during the period.
EngineHosts citedOf 25Reading
Perplexity2392%Most open. Third-party placement moves it fastest.
Claude2288%Nearly as broad; leans on roundups and community alike.
Google AI Overviews1768%Broad, but weighted to established publishers.
Grok1560%Mid-range; noticeably fond of community threads.
Gemini832%Narrow. Concentrates on a handful of large hosts.
ChatGPT312%Most closed. Third-party work barely reaches it.

This matters for sequencing. If the goal is to be cited in Perplexity or Claude, getting onto the roundups and threads in the table above is the direct route, and it is measurable within weeks. If the goal is ChatGPT specifically, that route is mostly closed — it cited three outside hosts in three weeks — and the work is slower and more structural. Selling those two as the same engagement is how AEO retainers lose money.

What our own pages achieved

We publish on our own domain too, and it is fair to ask what that produced. Across the same period the engines cited our own pages 106 times, against 2,061 for everyone else's.

Own-domain citations by page format, same period. The comparison library is roughly a third the size of the guide library and was cited four times as often.
Page formatCitationsShare of ownNote
Comparison pages /compare/*5855%"X alternatives", head-to-head pages
Homepage1817%Cited as an entity reference
Pricing page1110%Engines quote published prices directly
Guide articles /learn/*1413%The largest library on the site, the smallest return
Product docs55%Developer-facing pages

That last row is the one that cost us most to learn. The guide library is the biggest content investment on the site, produced steadily and to a consistent standard, and it returned 14 citations — 0.7% of the total evidence set. The comparison pages, a much smaller and less loved body of work, returned four times as many. Engines quote pages that resolve a decision, not pages that explain a topic.

What we would do differently

On this evidence, the ranking of effort for a company trying to enter generated answers in a competitive software category is: get onto the third-party roundups engines already read; publish comparison and pricing pages that state real figures; participate honestly in the community threads that carry 29% of the evidence; and only then expand the owned guide library. We had that order close to backwards.

Method

  1. Fixed question set. 22 buying-stage prompts a real purchaser would type — "best AI visibility tracking tool", "which tool includes Google Search Console", "how much do AI visibility tools cost", and named-competitor alternative queries. The set was fixed before measurement and not tuned afterwards.
  2. Daily runs across six engines. ChatGPT, Perplexity, Gemini, Claude, Grok and Google AI Overviews, 23 scans between 20 August and 11 September 2026. Every answer's source URLs were stored.
  3. Roll up by host. URLs grouped by host and counted. Rival-owned domains and engine-owned properties were excluded, so a mention on a competitor's own blog does not inflate the set.
  4. Open and read every cited page. The verification step. Each host's cited pages were fetched and read in full to determine whether our brand appears. Results recorded as present, mentioned-without-link, absent, or not-yet-read. Only the third counts as a gap.
  5. Report the unread separately. Five hosts had not been fetched at cut-off. They are excluded from the gap count and reported on their own so the headline figure is not inflated.
Disclosure and limits. The brand measured here is Cituna, an AI visibility product we operate, and the measurement was run on Cituna's own tracking infrastructure. We benefit if you buy it. Its visibility score in this category was 2 out of 100 at the time of measurement — we are reporting from the losing side of this data, not the winning one. The report covers one brand in one category over three weeks. It is a source-anatomy study, not a general law of AI search: a different category, especially a consumer or local one, may weight these sources differently. We have not tested that and do not claim it. Figures retrieved 11 September 2026. If you spot an error, tell us and we will correct it in public and note what changed.

The useful output is not the score. It is the list of specific third-party pages that already decide your category's answers, and whether you are on them. That list is different for every business, and it is the part you can act on this quarter.
