Measuring AI visibility and brand impact

A community speaker argued that rankings and clicks no longer equal business outcomes: visibility can rise while clicks fall, and traffic that follows an AI recommendation may arrive direct, through paid search or through another channel. In one controlled test with no other marketing changes, work on a brand's AI visibility coincided with more inquiries and a 36% rise in paid search click-through rate, figures from one unpublished test of one unnamed brand. The talk leaned on third-party studies (Similarweb on AI-recommended brands, a 2018 eye-tracking study on familiar brands) that Google has not published; Google's own position is that total organic clicks are relatively stable and that sites should judge visits by conversions and value, not clicks alone. This matches Google's Day 1 advice to measure success through metrics that matter to the business, and Google's AI features guide suggests tracking conversions and time on site to value traffic from AI features, because Search Console's generative AI report shows impressions but no clicks. Day 1's first lightning session, captured by a second recording, added community methods. One speaker proposed measuring AI search as a five-stage funnel (know, association, search, retrieval, selection) with metrics such as an AI bot allow rate, a brand association rate asked with web browsing switched off, and a brand co-occurrence rate in fan-out queries, arguing that most tracking covers only selection and copies rank tracking with invented prompts of unknown search volume. Another speaker said a study linking JSON-LD to AI visibility was followed by a controlled study that found no benefit, the markup being a sign of teams doing everything else right, that listicles earn more AI mentions because LLMs check that a thing exists rather than whether the content is honest, and cited a study (heard as Peec AI's) in which 43% of prompts produced fan-out queries in another language. An agency built its own AI visibility tracker to control the method, and a community speaker reported that on client sites AI systems cited information near the end of the content. In the Q&A Google said AI query data is hard to provide because AI questions do not map back to keywords and the data would have to be grouped to protect privacy while staying useful. Author’s view: in Peec AI's published study the 43% is the share of fan-out searches for non-English prompts that ran in English, not a share of prompts. Google's AI optimisation guide says structured data is not required for generative AI search, so use markup for rich results and clear data, not as an AI-visibility lever.

What to do

  • Report conversions and traffic by channel, and ask the paid search team for click-through data, rather than judging SEO on organic clicks alone.
  • Before testing AI visibility, record the period, the baseline and every other marketing change, and compare with a control area.
  • Measure AI visibility across stages (whether models know, associate, search for, retrieve and finally select the brand), not only mentions in answers.

Google's AI optimisation guide says structured data is not required for generative AI search and needs no special schema.org markup, and on Day 2 Google said raw schema.org is generally not put into model context (D2-C477); use markup for rich-result eligibility and clear data, not as an AI-visibility lever.

A community speaker cited a recent Similarweb study as showing that being recommended in AI-driven services multiplies a brand's chance of getting traffic downstream; a Similarweb study reported in June 2026, probably the one meant, found brands recommended by ChatGPT 2.5 times more likely to get a site visit within 7 days (US desktop data, finance, travel and beauty).

In an August 2025 post, Google's Head of Search wrote that total organic click volume from Google Search to websites had been relatively stable year-over-year and that Google was sending slightly more quality clicks (clicks where users do not quickly click back) than a year earlier; the post gave no figures.

The two studies cited on stage are third-party and narrow (Similarweb, 2026: ChatGPT only, US desktop, three industries; Red C, 2018: eye-tracking on shopping-type searches), so quote them with that scope; Similarweb found that 55.9% of the resulting site traffic came from branded searches, the step after an AI recommendation in the speaker's customer journey.
