Evidence

Does AEO work?

Partly, and less certainly than it is sold. The evidence is one benchmark paper, newer preprints and a lot of vendor reporting.

The short answer

Partly. The strongest public evidence is a 2024 benchmark: adding sources, quotations and statistics raised visibility by up to 40% on older engines. Newer data says retrieval matters most. The effect on your site is unknown until you measure it.

What ranked on 18 September 2026: The academic query returns the arXiv paper, Wikipedia and Google's guidance. The commercial phrasing returns no primary evidence. Same subject, different standards of proof.

What the main study found

Aggarwal et al. tested edits to a source document against a benchmark of queries.

  • Citations, quotations and statistics helped most
  • Keyword stuffing gave little to no gain
  • Up to 40% is a benchmark result, not a client outcome

What newer data adds

A 10 October 2026 preprint studied 158,099 answers. Treat it as unreviewed.

  • Every cited ChatGPT page was first retrieved by its own search
  • Retrieval explained about 32% of variation, page properties 2.8%
  • Brand names alone reordered products with identical facts

Why vendor evidence is weak

The problem is structural, not dishonest.

  • No control group. Updates and your edits look identical
  • Sampling noise. The same prompt cites different sources
  • Selection. Published case studies show the ceiling
  • No shared definition of a citation

Test it on your own site

A cheap, defensible test beats every published average.

  • Fix 20 to 40 buyer prompts and never edit them
  • Sample weekly and record mention and description
  • Change one class of thing at a time
  • Judge the trend over six to eight weeks, not one sample

Questions

Asked most.

Is there proof AEO increases revenue?

Not in controlled public form. AI platforms were 0.32% to 1.08% of site traffic in two studies, so measure your own.

How long does it take to see results?

A trend needs six to eight weeks of sampling to separate from noise. Anyone promising faster is describing hope.

What is the cheapest thing that helps?

Rewrite your top pages so the first paragraph answers the question alone and names the entity. It costs a day and helps human readers too.
