GEOforge Research · AI Citations
We analysed 1.35 million citations. AI doesn't read the web. It reads the same few dozen sites, over and over.

"Get cited by AI" has become the GEO mantra. But cited where? The data shows the field is far narrower, and far more winnable, than "the whole web" suggests.
A citation is a source the model leans on to build its answer: the pages and domains it pulls facts and names from when it responds to a query. Citations matter because they're upstream of mentions. If your brand shows up in the sources AI trusts, it shows up in the answer. If it doesn't, no amount of on-site optimisation will put it there. So the practical question is which sources actually carry that weight.
Across 1.35 million citation instances spanning 12,317 distinct domains, the distribution wasn't remotely even. The top 1% of domains accounted for 44.5% of everything cited. The top 50 domains alone supplied 28.9%. The top 10 carried nearly 11% on their own. A long tail of more than twelve thousand sites splits what's left.
AI doesn't survey the open web for every answer. It returns, again and again, to a small set of sources it treats as authoritative. Get into that set and you're cited everywhere. Stay out of it and you're competing in a tail that barely registers.
Some are universal. Wikipedia appeared in the citation set for 16 of the 21 brands we track. Reddit showed up for 14. Forbes for 11, Gartner for 8, G2 for 6. Others are category-specific heavyweights, like Semrush and Clutch in marketing, or the scientific and vendor-documentation domains that dominate technical fields. The mix shifts by industry, but the structure is always the same: a handful of sources do most of the work.
| Source | Brands it was cited for |
|---|---|
| Wikipedia | 16 of 21 |
| 14 of 21 | |
| Forbes | 11 of 21 |
| Gartner | 8 of 21 |
| G2 | 6 of 21 |
Of 1.35 million sources ChatGPT cited, 44.5% came from the top 1% of domains. You don't need to be everywhere. You need to be in the few dozen places AI keeps going back to.
A power law means the problem is bounded. "Earn citations across the web" is paralysing. "Earn your place in the 50 to 100 sources that drive nearly half of AI's citations in your category" is a project plan. Identify the recurring domains for your space, audit which ones already mention competitors and not you, and go earn presence there deliberately. That's a finite, prioritised list, not an ocean.
Tracking which sources AI trusts is table stakes. Getting into them is the work that moves your visibility.
GEOforge maps the domains driving AI citations in your market, shows where competitors are cited and you aren't, and builds the presence to close it.

Corpus: 1,352,770 citation instances across 12,317 distinct domains, drawn from 51,391 classified citation source URLs across 21 tracked brands, measured April–June 2026. "Top 1%" is the highest-frequency 1% of domains by citation volume. Cross-category source counts reflect how many of the 21 brands each domain was cited for. Figures are ChatGPT-specific; cross-engine results may differ.
