AI-generated content
34 established claims - 1 refused by the grounding gate
Verdict
Google's published guidance as of 2023-02-08 and 2025-12-10 states that appropriate use of AI is not against its guidelines, but using AI primarily to manipulate rankings violates spam policy, scaled generation without added user value may violate scaled content abuse policy, and AI content gets no special ranking gains. Ahrefs' April 2025 study of 900,000 new pages found 74.2% contained AI-generated content, and its July 2025 study of 600,000 ranking URLs found a near-zero correlation of 0.011 between AI content percentage and ranking position. The empirical picture is not fully consistent: another Ahrefs claim states higher AI use is correlated with lower ranking positions, and Ahrefs' June 2026 findings associate higher AI use with lower indexation and lower rankings while also showing no hard cutoff and some fully AI pages in top rankings. The direct effect of AI content on rankings is therefore not settled.
Written from the 34 established claims below, then checked against them. How that works.
Documented position12
What the operator of the system says in its own documentation.
AI-generated content is documented by Google's Search Central documentation page 'Google Search's guidance on using generative AI content on your website' as potentially violating Google's spam policy on scaled content abuse when created using generative AI tools to generate many pages without adding value for users.

However, using generative AI tools or other similar tools to generate many pages without adding value for users may violate Google's spam policy on scaled content abuse .
Google's Search Central documentation page "Google Search's guidance on using generative AI content on your website" states that under Google Merchant Center policy AI-generated images must contain metadata using the IPTC DigitalSourceType TrainedAlgorithmicMedia value.

- Google's Search Central documentation page on AI-generated content, titled 'Google Search's guidance on using generative AI content on your website', points readers to sections 4.6.5 and 4.6.6 of the Search Quality Raters guidelines.
- The Search Quality Raters guidelines sections 4.6.5 and 4.6.6, to which Google's Search Central documentation page on AI-generated content points readers, are for evaluating scaled content abuse and low-effort main content.

You might find value in looking at the Search Quality Raters guidelines on how to evaluate both scaled content abuse (section 4.6.5) and main content created with little to no effort, little to no originality, and little to no added value (section 4.6.6).
AI-generated content's documented position, as stated on Google's Search Central documentation page 'Google Search's guidance on using generative AI content on your website', is that search raters' ratings do not directly influence ranking.
1 quote from 1 source
These guidelines are not a guide to ranking first in Google; they're used by our search raters to help evaluate the performance of our various search ranking systems , and their ratings don't directly influence ranking.
Google's Search Central documentation page 'Google Search's guidance on using generative AI content on your website' advises site owners who automatically generate AI-generated content to consider adding information on how the AI-generated content was created.
1 quote from 1 source
If you're automatically generating content, consider adding information on how your content was created in a way that makes sense for your audience, such as by providing more background information on how automation was used and adding image metadata .
The Google Search Central blog post "Google Search's guidance about AI-generated content" states that using automation, including AI, to generate content with the primary purpose of manipulating ranking in search results is a violation of Google's spam policies.

Is AI content against Google Search's guidelines?
Appropriate use of AI or automation is not against our guidelines. This means that it is not used to generate content primarily to manipulate search rankings, which is against our spam policies .

Will AI content rank highly on Search?
Using AI doesn't give content any special gains. It's just content. If it is useful, helpful, original, and satisfies aspects of E-E-A-T , it might do well in Search. If it doesn't, it might not.
The Google Search Central blog post 'Google Search's guidance about AI-generated content' advises adding AI or automation disclosures when it would be reasonably expected.

Should I add AI or automation disclosures to my content?
AI or automation disclosures are useful for content where someone might think "How was this created?". Consider adding these when it would be reasonably expected.

Practical effect1
What is observed to happen in practice, as distinct from what is documented.
The Ahrefs blog post 'Google Doesn't Punish AI Content; It Punishes Bad Content (331k Pages Studied)' reports finding no obvious hard cutoffs suggesting a binary AI classifier prevents AI-generated pages from ranking highly or entering the index.
1 quote from 1 source
There are no obvious hard cutoffs suggesting a binary AI classifier is preventing AI-generated pages from ranking highly or making it into the index. Instead, we see a gradual gradient: performance generally worsens with increasing AI use… probably because content quality generally worsens with increasing AI use.
Disputed between sources2
Sources that do not agree, presented without picking a winner.
- One Ahrefs blog post states that there is no clear relationship between how much AI-generated content a page has and how highly the page ranks on Google.
- Another Ahrefs blog post states that higher use of AI-generated content is correlated with lower ranking positions.
2 quotes from 2 sources
There is no clear relationship between how much AI-generated content a page has and how highly it ranks on Google. This suggests that Google neither significantly rewards nor penalizes pages just because they use AI.
But although our data suggests that higher AI use is correlated with lower ranking positions, it also suggests that it is possible for fully AI-generated content to rank in positions 1-3.
Echoed without a primary source3
Widely repeated in the field, but traceable only to other repetitions. Listed because knowing something is merely echoed is worth as much as knowing it is documented.
- The thestacc.com article "AI Content Statistics 2026: 74% of New Pages Use AI (50+ Stats)" restates the Ahrefs 74.2% figure about AI-generated content as a 2026 statistic.

AI Content Statistics 2026: 74% of New Pages Use AI (50+ Stats)
74.2% of newly created web pages now contain AI-generated content. That number comes from an Ahrefs study of 900,000 pages published in April 2025. Only 2.5% are pure AI. The rest are human-AI blends.
The Europol report line says AI-generated content may account for as much as 90 percent of online content by 2026.

Experts: 90% of Online Content Will Be AI-Generated by 2026
“Don’t believe everything you see on the Internet” has been pretty standard advice for quite some time now. And according to a new report from European law enforcement group Europol, we have all the reason in the world to step up that vigilance.
“Experts estimate that as much as 90 percent of online content may be synthetically generated by 2026,” the report warned, adding that synthetic media “refers to media generated or manipulated using artificial intelligence.”
Refused1
Claims the research produced that the grounding gate would not accept, with its reason. They are here because a site that only shows what passed gives you no way to judge whether the gate does anything.
Show what was refused
The Futurism article headlined "Experts: 90% of Online Content Will Be AI-Generated by 2026" presents a Europol report line as a flat prediction about AI-generated content.
Refused: The quotes show the article attributes the statement to a Europol report, which itself uses the phrase 'experts estimate,' not an unqualified flat prediction.
Unsupported: as a flat prediction
