This is the September 2026 edition of the Thin Content Checker 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 August 2026

36 → 36 Median score no change
28% → 21% Scored 80+ −7 pp
2.9 → 3.0 Issues per scan +0.1

The biggest check-level move was “Above the thin-content floor”, which went from 53% in August 2026 to 62% in September 2026 — it went unmet in a larger share of this month’s sample.

Reading a monthly difference. Each month is a separate sample, and its size changes from month to month. A change in sample size can move a median and a distribution by itself, so a monthly difference should not be mistaken for 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 Thin Content Checker between August 2026 and September 2026
Thin Content Checker — check-by-check change from August 2026 to September 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.

How the scores fell

This is how 3,742 scans spread across the five score bands in September 2026. The distribution banks up against the floor: most scans in this sample score low, so even a middling result sits above the majority of them.

The rate is the share of scans in which a SeoMods check was not met. It is SeoMods’ criterion, not Google’s assessment of these pages. “Hard fail” means the check’s full weight is deducted from the SeoMods score; “partial” means part of it.

What this score does not measure

  • 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.
  • It is not an organic traffic estimate. No click, impression or visit data goes into it.
  • It does not represent the whole of the real user experience. What is measured is one URL’s HTML and server response at the moment of the scan.

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.

Frequently asked questions

Does this page ever change?

Its figures do not. A dated record is only useful if it stays put: someone citing the September 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.
