Every site on the board.
Score is the scanner's overall grade out of 100. AEO is the subset of signals that decide whether an answer engine can cite a page. Unscanned sites sit at the bottom until the next weekly crawl.

Cited by AI answer engines.
In the week of Oct 25, 2026, b/cited asked ChatGPT (gpt-4.1-mini), Claude (claude-sonnet-4-6) and Perplexity (sonar) 5 email marketing buying questions and recorded which sites each answer cited. 15 of 15 prompt-and-engine pairs completed.
This is engine output, not a scanner score. A citation is not a recommendation or an endorsement, and the prompts are a sample, not a census. Counts are out of the prompts each engine actually answered that week.

How the scores are calculated.
30+ signals, nine categoriesIndexing, metadata, social cards, structured data, AEO, international, mobile, security headers, and Core Web Vitals.
An AEO score on topWeights the signals that decide whether an answer engine can cite a page: llms.txt, AI crawler allowance in robots.txt, and FAQPage and Author schema.
Re-scanned weeklyEvery domain is crawled again each week. Grades are the scanner's, not editorial picks.
Citations kept apartEach category also shows which sites three answer engines cited on a fixed set of buying questions. Engine output, dated, never a rating.
