The AEO Index · Edition 1, October 2026

Who AI recommends, in 15 software categories.

We asked ChatGPT and Perplexity the questions software buyers ask, like “what is the best CRM for startups?”, and recorded which brands each one named, in what order, and which sites they cited. 30 answers, 98 brands.

brands named per answer, on average

Key findings

  • Answers are short lists. Each answer named 5.4 brands on average. If you aren’t in the top five or six for your category, you usually aren’t mentioned at all.
  • The engines agree on the leader 10 times out of 15. They split on HR software, product analytics, e-signature, website builders, AI meeting notes. In those categories the first-named brand depends on which AI the buyer uses.
  • Many brands appear in only one engine. 33 of the 98 brands we recorded were named by just one of the two engines. Being recommended by ChatGPT says little about Perplexity, and the reverse.
  • Review sites and lists decide the answers. The most-cited sites were techradar.com, zapier.com, softwarecompare.net, zoho.com, dupple.com. Software vendors’ own blogs were cited too, mostly in their own categories.

The sites AI read most

Every answer cites the pages it was built from. These sites were cited in the most categories, across both engines. For most software, being listed and well described on them matters more than any change to your own homepage.

Method

  • When: October 2026 (collected 2026-10-22).
  • Engines: ChatGPT (logged out, web search on) and Perplexity (Sonar, web search on), both asked from the United States.
  • Questions: one plain buyer question per category, asked once per engine, with no follow-ups.
  • Counting: a brand counts when the answer names it as an option. Order is where it is first named.
  • Limits: AI answers vary between runs, users and locations. This is one snapshot. Later editions will add more runs, more engines and more categories.

About the AEO Index.

What is the AEO Index?

The AEO Index is a free benchmark by AEOIndex of which software brands AI answer engines recommend. Each edition asks ChatGPT and Perplexity the same buyer questions, records which brands they name and in what order, and which websites they cite.

How is the AEO Index score calculated?

For each answer, the first brand named gets 10 points, the second 8, the third 6, the fourth 4 and any later brand 2. A brand’s score adds its points from ChatGPT and Perplexity and scales the total to 100, so a brand named first by both scores 100.

Why do ChatGPT and Perplexity recommend different brands?

They run different searches, read different pages and weigh them differently. In this edition they named a different brand first in 5 of 15 categories. The pages each one read, mostly review sites and “best of” lists, largely decide who gets named.

How can my product get into AI recommendations?

Get onto the pages AI tools read for your category (review sites, comparison articles, “best of” lists), make your own pages state clearly who you’re for and what you cost, and let AI crawlers read your site. Our free AEO audit checks the technical part.

Can I suggest a category for the next edition?

Yes. Email hello@aeoindex.co with the question your buyers ask, and we’ll consider it for the next edition.
