GEO is a long name for a simple job: making sure that when an AI assistant answers a question your customer asked, your business is the one it names.
Similarweb reports a 43%-plus AI Overview appearance rate in the United States. Trackers disagree, with estimates from 18% to 48%, mostly because they sample different query mixes — question-style and commercial searches trigger one far more often.
SparkToro, working from Similarweb clickstream data for January to April 2026. Their earlier baseline used a different panel, so the rise over time is not a clean comparison, and the figure excludes Google's mobile app.
From the one randomized experiment on this, by researchers at the Indian School of Business and Carnegie Mellon. It is a pre-registered working paper rather than peer-reviewed work, and nobody has replicated it yet.
| SEO | GEO | |
|---|---|---|
| The goal | Rank in a list of ten links | Be named in a single answer |
| The surface | A results page the user scans | A paragraph the user reads and stops |
| What decides it | Mostly your own pages and links to them | Mostly third-party coverage about you |
| How you measure | Rankings and clicks | How often you are named, across repeated runs |
| Failure mode | You are on page two | You do not exist for that customer |
Comparison articles, review platforms, forum threads and trade press. These are what an assistant retrieves when it needs to name a few companies, and they are mostly sites you do not control.
Once you are a candidate, your pages get read for specifics — pricing, features, who it is for. Which is why a brand can be named and still described wrongly.
Assistants lift sentences that answer a question directly. A page that states its answer plainly near the top gets quoted more than a better page that buries it.
The same facts about you, stated the same way across many sources, make a model more willing to name you. Contradictory listings do the opposite.
