A growing share of buying research now happens inside generative chat, ChatGPT, Gemini, Perplexity, not a search results page. GEO is the work of becoming the source those engines quote when someone asks about your space.
This audience is no longer small. The major generative engines reach hundreds of millions of weekly and monthly users between them, and the people arriving from AI answers engage and convert notably better than average.
And there’s a real, peer-reviewed playbook for winning citations. GEO is learnable, measurable work, built on being the trustworthy, cited source. Here’s the data.
Generative engines reach hundreds of millions.
GEO matters because the audience is at search scale. ChatGPT reached roughly 900 million weekly active users, and Google’s Gemini app surpassed 750 million monthly users, roughly doubling year over year. Your buyers are increasingly asking these tools for recommendations.
When an engine answers “what’s the best option for X,” being one of the sources it cites is the new version of showing up. That’s what GEO wins.
The audience GEO competes for
The levers that win AI citations are proven.
GEO isn’t guesswork. The peer-reviewed paper that coined the term (from Princeton, Georgia Tech, the Allen Institute for AI, and IIT Delhi) tested optimization tactics and found adding citations, quotations, and statistics boosted a source’s visibility inside generative engines by up to 40%.
Every winning lever is a “be the trustworthy source” move: cite your sources, quote authorities, back claims with data. That’s editorial discipline, and it’s exactly how we build GEO content.
What lifts a source’s GEO visibility
GEO-bench (Aggarwal et al., KDD 2024).
Source: GEO: Generative Engine Optimization (KDD 2024)Citing sources can lift an underdog 115%.
GEO is especially powerful if you’re not the incumbent. In the same study, adding source citations lifted visibility for a 5th-ranked site by 115%, while the top-ranked site lost ground from the identical change.
Unlike classic search, where the big get bigger, generative engines reward being the genuinely useful, well-cited source. That’s an opening for brands willing to do the work.
The great equalizer
AI visitors engage and buy more.
The traffic is small today but unusually good. Adobe Analytics found visitors arriving from AI sources spend 48% longer on site, browse 13% more pages per visit, and engage 12% more than other visitors. They arrive pre-qualified by the AI.
That’s the case for GEO now, while it’s early: low volume, high intent. Being the cited source puts you in front of buyers who are already most of the way to a decision.
How AI traffic behaves
GEO compounds with the authority you already build.
GEO isn’t a separate universe from SEO. Branded web mentions are the single strongest correlate of AI visibility (0.664), and 76% of AI Overview citations come from pages that rank in the top 10. The brand authority that wins rankings is the same authority that wins citations.
So we build GEO on a strong SEO foundation: original data, quotable statements, citations, and the digital PR that gets you mentioned across the web. One program, pointed at the generative answer.
Through rigorous evaluation, we demonstrate that GEO can boost visibility by up to 40% in generative engine responses.

If your brand is mentioned in a ton of different places on the web, that correlates very highly with AI visibility.
