This is the August 2026 edition. 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 the current picture go to SEO Score Benchmarks, which is refreshed each revision. This page never is.

This is the first edition in the series. There is no earlier month to compare against yet, so these figures are the baseline. Every edition after August 2026 will also show what moved since the one before it.

How the scores fell

This is how the three tools’ scores spread across the five bands in August 2026. Every row totals 100%; what matters is not the height of any one band but the shape of the spread.

Every tool, ranked

The three tools above are the ones with their own detail pages. The table below ranks all 25 tools that reached a publishable sample in August 2026, by median score. The finding is not in any single row but in the shape of the table: the tools that measure whether a page loads sit at the top, and the tools that measure whether it is ready to be cited sit at the bottom.

“Middle half” is the range the middle 50% of results fall into (25th–75th percentile). A narrow band means the tool scores most sites alike; a wide one means sites genuinely diverge on that measure.

This month’s sample

In August 2026 the three featured tools recorded 4,477 successful scans across 3,049 unique domains in 14 countries. How the sample is collected, how it is anonymized and where its limits are is set out in the methodology on the hub — it governs the whole series, so it is stated there once.

Frequently asked questions

What was the average SEO score in August 2026?

In August 2026 the All-in-One SEO Audit had a median of 76/100 and a mean of 73.1. 40% of scans reached 80 or above, while 21% landed in the 40–59 band. These figures are frozen and will not change.

Why is this page never updated?

Because a dated report is only useful if it stays put. Someone citing the August 2026 figures today has to find the same numbers at the same URL two years from now. For the current picture, go to the benchmark hub, where the figures are refreshed each revision. A new edition is published at the end of every month.

Which check failed most often in August 2026?

Author and date information, missing from 91% of audits, followed by the text-to-HTML ratio (85%) and a missing llms.txt (71%). On the AI visibility side llms.txt led again, at 70%. On meta tags the most-failed check was title length: the title sat outside the 30–60 character range in 52% of scans.
