AI-heavy pages flip up at each spot in Google’s prime 10. However pages the detector reads as largely AI-written sit decrease in these outcomes than pages with little AI textual content, and fewer of them had been discovered within the index in any respect, in line with new information.
The scores come from Ahrefs’ personal AI detector, which the corporate sells by Web site Audit and Web site Explorer. It says the instrument isn’t excellent and doesn’t work the identical approach as something Google would possibly use. Each quantity right here is an estimate of how a lot of a web page reads as AI-written, not a file of who wrote it.
Since 2023, Google has mentioned that it rewards high quality regardless of how a web page was made, and that automation aimed primarily at gaming rankings counts as spam.
Greater than half of the pages in Google’s prime three search outcomes (54.7%) have lower than 20% AI-generated content material. So, subsequent time somebody says that the majority prime search outcomes are largely written by machines, you possibly can hold that quantity in thoughts.
The place AI-Heavy Pages Rank
Pages scoring beneath 50% AI textual content took 82.2% of the highest three spots. Pages the detector scored at a full 100% had been uncommon however actual, at 5.3% of top-three pages.
Pages scoring 80% or increased accounted for 8.4% of first-place outcomes and 11.7% of tenth-place outcomes. The common rating rose from 27.1% at place 1 to 30.9% at place 10, though the rise wasn’t linear, since place 9 scored increased than place 10.
These statistics are based mostly on about 150,000 pages from the highest 10 outcomes of 100,000 searches in June 2026, every no less than 350 phrases lengthy. The headline depend from Ahrefs lists 331,000 pages, representing a number of totally different samples.
Ahrefs Discovered Fewer AI-Heavy Pages In The Index
Ahrefs discovered 49.28% of pages with the least AI textual content in Google’s index. This proportion drops to 43.38% for pages scoring between 20% and 50%, 40.72% for these between 50% and 80%, and 40.35% for pages at 80% or increased.
Larger AI Scores, Fewer Pages Discovered In The Index
Share of roughly 100,000 pages assembly no less than one among Ahrefs’ three index indicators, grouped by the estimated share of textual content flagged as AI-generated.
The report’s authors describe this variation as “significant however removed from disqualifying.” Since Google doesn’t give direct index entry, Ahrefs measured this in 3 ways: whether or not a web page ranked for no less than one key phrase, had a Search Console impression since January 2026, or appeared in a website: search.
Any one among these means the web page is sort of definitely listed. Nonetheless, pages should still be listed even when they don’t meet these standards, so these figures are minimal estimates. That test used a separate pattern of roughly 100,000 pages, one per area.
What Modified Since Ahrefs’ 2025 Information
A 2025 model ran throughout 600,000 pages, trying on the prime 20 as a substitute of the highest 10. It put the correlation between AI rating and rating place at 0.011, successfully zero, and mentioned there was no clear relationship between the 2. SEJ coated it when it ran.
The brand new one says increased AI use strains up with decrease positions. It provides no such quantity, and nonetheless calls the distinction light. The 2 used totally different samples, went totally different depths into the outcomes, sorted pages into totally different teams and revealed totally different measures, in order that they don’t line up cleanly. The clearest change is the wording.
Why This Issues
Nothing right here backs up holding off on AI assist for concern that Google will spot the output and drop it. Pages the detector scored at a full 100% held top-three spots on this pattern.
Larger scores lined up with decrease rankings in a single pattern and fewer listed pages in one other. Report co-author Ryan Legislation reads this as high quality declining as AI use rises.
These samples didn’t consider elements like content material depth, inside linking, originality, or factual accuracy.
A excessive rating is a motive to take a look at a web page. It isn’t proof the web page is weak, or that Google did something to it.
Wanting Forward
This measures how a lot of a web page reads as machine-written, simply as AI assist turns up inside on a regular basis writing instruments. The extra that spreads, the much less a detector rating might inform you about how a web page was truly made.
The larger questions, those SEJ contributor Dan Taylor has been asking about, are round publishing at scale and whether or not scaled AI content material is well worth the crawl price range it makes use of.
