This is the October 2026 edition of the AEO Checker (Answer Engine Optimization) benchmarks. Every figure below comes only from scans run inside that month, and none of them will change again — a rate you quote today will still be at this address years from now. For every published month added together, go back to the tool's own page: that one is refreshed each time a month is added, and the figures here never are.

A monthly snapshot does not change after it is published: the figures on this page stay exactly as they were frozen on that date.

What changed since September 2026

40 → 40 Median score no change
1% → 2% Scored 80+ +1 pp
6.0 → 5.7 Issues per scan −0.3

The biggest check-level move was “Exactly one clear H1”, which went from 49% in September 2026 to 41% in October 2026 — it went unmet in a smaller share of this month’s sample.

Reading a monthly difference. The two months are close in size, but they are not the same set of sites. A different mix of sites can move a median and a distribution by itself, so a monthly difference is not a change in scores: it does not show that sites improved or got worse.

Change in the share of scans not meeting each SeoMods check on the AEO Checker (Answer Engine Optimization) between September 2026 and October 2026
AEO Checker (Answer Engine Optimization) — check-by-check change from September 2026 to October 2026, in percentage points.

Moves under a point are marked as no change. The two months are independent samples of a shifting set of sites, and a difference that small is measurement noise.

What this score does not measure

  • It is not a direct measurement of the signals every AI system uses. Which system uses which signal, and how, is not public; the score measures the checks SeoMods chose.
  • It does not measure whether a page is actually cited in AI answers. It measures readiness on the page, not what any assistant returned.
  • It is not a Google ranking. A high score does not guarantee a better position, and a low one does not mean Google has penalised the page.

About this benchmark. This benchmark is calculated from data on the sites SeoMods has scanned. The results do not necessarily represent all websites, or a random selection of them. The scores express SeoMods’ own measurement and scoring criteria; they are not ranking, quality, E-E-A-T or AI visibility scores issued by Google. Sample, anonymization and licence: the full methodology.

Does this page ever change?

Its figures do not. A dated record is only useful if it stays put: someone citing the October 2026 figures today has to find the same numbers at the same URL years from now. The one thing added afterwards is a pointer to the next month's edition once that is published — the data is left exactly as it was. For every published month added together, see this tool's own benchmark page, which is refreshed each time a month is added.
