This is the October 2026 edition of the Topical Authority Map 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.
| Data period | 1 October 2026 – 31 October 2026 |
|---|---|
| Unique sites | 3,322 |
| Total scans | 3,641 |
| Benchmarks / tools | 1 — Topical Authority Map, one of the 25 tools in this edition |
| Minimum sample | at least 500 scans per tool in the month |
| Data frozen on | 11 November 2026 |
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
The biggest check-level move was “Structured data present”, which went from 62% in September 2026 to 48% 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.
| Check | Not met then | Not met now | Change |
|---|---|---|---|
| Structured data present | 62% | 48% | −14 pp |
| Topic present in the homepage title | 39% | 45% | +6 pp |
| Topic reinforced in headings | 57% | 52% | −5 pp |
| Enough supporting pages | 32% | 29% | −3 pp |
| Internal linking depth | 27% | 24% | −3 pp |
| Covers the topic’s subtopics | 90% | 88% | −2 pp |
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 3,641 scans spread across the five score bands in October 2026. The spread is wide and fairly even: in this sample sites land at very different levels on this measure.
- 0–19
- 20–39
- 40–59
- 60–79
- 80–100
| Score band | Topical Authority |
|---|---|
| 0–19 | 21% · 773 |
| 20–39 | 18% · 650 |
| 40–59 | 41% · 1,479 |
| 60–79 | 11% · 400 |
| 80–100 | 9% · 339 |
| Total runs | 3,641 |
Which SeoMods checks went unmet
The SeoMods checks that were not met in Topical Authority Map scans during October 2026. What each check means and what to do about it is on the tool's own benchmark page; this page is the record of the month.
| Check | Not met (share of scans) | Weight |
|---|---|---|
| Covers the topic’s subtopics | 88% | Hard fail |
| Topic reinforced in headings | 52% | Partial |
| Structured data present | 48% | Partial |
| Topic present in the homepage title | 45% | Partial |
| Enough supporting pages | 29% | Partial |
| Internal linking depth | 24% | Partial |
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.
The weakest areas that month
This month’s sample

How the sample is collected, how it is anonymized and where the method's limits lie govern the whole series, so they are set out once in the methodology on the hub.
| Tool | Domain endings in the sample |
|---|---|
| Topical Authority | .com 46% · .org 10% · .uk 5% · .io 3% · other 36% |
What this score does not measure
- It is not a topical authority metric published by Google. Google publishes no such score.
- It does not measure a site’s actual expertise or the quality of its content. It measures the crawlable traces of coverage and internal linking.
- 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.
Frequently asked questions
What was the median Topical Authority Map score in October 2026?
In October 2026 the median was 47/100 and the mean was 45.3. 9% of scans reached 80 or above. These figures are frozen and will not change.
Which SeoMods check went unmet most often in October 2026?
“Covers the topic’s subtopics”, which was not met in 88% of scans, followed by “Topic reinforced in headings” at 52%.
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.
