Original research

Measured studies on what AI answer engines cite

What this research covers. AEOForged runs live questions to ChatGPT, Gemini, and Perplexity, records every cited source and every miss, and publishes the article, methodology, and dataset. The live corpus spans 96 questions and 3,563 recorded citations across four independent studies. These sweeps do not cover Google AI Overviews.

Each study uses Wilson 95% confidence intervals and a same-day variance panel. Raw datasets are published alongside every article. Numbers are frozen at measurement — nothing is invented after the fact. Purchasable sector editions live on Sector Intelligence; packages that use this measurement stack are on Pricing. Research updated .

Live dogfood measurement

Not a frozen sector study — our own domain on the same citation instruments, updated as daily checks land. Also at /research/live-citation-board.

Citation Lab editions

Monthly measured experiment pools. Every figure is measured on the named instrument versions; no client is named. All Citation Lab editions.

No edition has been published yet.

First-party field notes

Dated observations from sites we operate. Same instruments, not a sector census. Also at /research/llmstxtgen-chatgpt-referrers.

AI sector reports

Product-led guide to purchasable sector artifacts — distinct from first-party dogfood above. Storefront: /intel.

What the measurements say

Source-list rates by engine, then the July citation-mix rollup those rates sit beside.

Individual studies

One measured paper per topic. Each line: the finding, then article · methodology · dataset.

How citation rate is measured

A citation rate here is the share of live engine answers that named a given domain. We report Wilson 95% confidence intervals on those shares. A variance panel repeats the same queries the same day so flip rates sit next to the headline.

GEO (Generative Engine Optimization) and Answer Engine Optimization are the category labels under study. Engines covered are ChatGPT, Gemini, and Perplexity. These sweeps do not cover Google AI Overviews.
