A study of 2,970 AI engine answers reveals agencies ranking in Google's top 10 appear in ChatGPT, Perplexity, and Google AI Overviews only 9.7% to 10.3% of the time, showing the two systems reward completely different signals.
For decades, ranking high on Google meant visibility. But a new benchmark shows that assumption is cracking. LoudFace analyzed 2,970 answers across ChatGPT, Perplexity, and Google AI Overviews and found something stark: agencies that rank in Google's top 10 for the same search appear in AI engine recommendations only 9.7% to 10.3% of the time.
That gap matters. It means your ranking and your recommendation are almost completely decoupled. A business owner running ads to drive clicks to a top-ranked page, or an agency investing in SEO to hold position one, is making bets on a visibility channel that does not automatically transfer to the platforms customers increasingly use to find answers.
Google search rewards domain authority, link volume, and time-on-page. An agency that has accumulated backlinks and brand mentions over years climbs the rankings. It feels like proof of quality.
AI engines operate differently. They scan for sources that appear in their training data and that directly answer the user's question with cited evidence. An agency with strong ranking signals but no published research, no reviews, and no clear answer to the specific question gets skipped. An agency that publishes transparent case studies, collects verified reviews, and answers the exact customer question gets cited, even if it does not rank.
The 90% gap is not a ranking bug. It is a channel separation.
If you are a manufacturer, contractor, or shop owner hiring an agency or evaluating your own visibility: you now have two separate audiences to reach. Some customers open Google. Others open ChatGPT or Perplexity. Most use both, but not in the same session. Your page one ranking does not deliver both.
For decades, 'winning search' meant winning Google. Now it means winning both. The LoudFace data shows that less than 1 in 10 top-ranked pages clear the bar for AI citation. If your visibility depends entirely on one channel, you are invisible on the other.
How WebKing runs this
We track how agencies and services appear across AI engines and Google search simultaneously, so you know which visibility channel to invest in and which to monitor.
Probably not. LoudFace's analysis of 2,970 answers found that agencies ranking in Google's top 10 appeared in AI engine recommendations only 9.7% to 10.3% of the time, meaning the systems use different criteria to surface results.
AI systems prioritize cited sources and answer relevance over link authority; Google prioritizes link signals and domain authority. An agency might rank well on Google without being trusted enough to cite in an AI response.
No, they're separate channels. The study shows less than 10% overlap, meaning most customers still find you through one or the other. You need visibility in both, but strategies differ for each.
AI engines cite sources that appear authoritative and directly answer the user's question; they prioritize published research, reviews, and clear expertise over domain age. Being rankable and being citable are different things.
