For two years, a persistent rumor has been circulating among website publishers: Google would systematically penalize texts written with the help of artificial intelligence. The reality is more nuanced. Le AI-generated content is not prohibited by the search engine: what Google penalizes are pages mass-produced, without proofreading or added value for the reader. An essential distinction for anyone managing a website, an online store or a blog, and one that is better understood before rethinking an entire editorial strategy.
What Google's official rules actually say
The search engine's position has been public since February 2023 on its Search Central blog: using automation, including artificial intelligence, “with the primary purpose of manipulating ranking in search results” falls under spam. Conversely, a useful, original and reliable text remains perfectly acceptable, regardless of how it was produced. Google says it rewards the quality of content, not the method used to write it.
Concretely, pages are evaluated through the so-called E-E-A-T lens: experience, expertise, authority and trustworthiness. A signed, documented article that provides verifiable information checks these boxes — whether an AI tool was used as a draft or not. A topic we follow closely in our section High Tech, AI & Software.
“Large-scale content abuse”: the red line
The real tightening dates back to March 2024, when Google incorporated into its anti-spam rules the notion of scaled content abuse, or large-scale content abuse. Targeted are numerous and non-original pages, created primarily to capture traffic, and this “regardless of how they were produced”: automatic generation, human writers, or a combination of both. The rule therefore does not target AI as such, but the industrial production of uninteresting texts.
Along the same lines, the quality raters who help Google calibrate its algorithms are now trained to spot mass-produced content, with no effort or originality, and to give it the lowest rating on their scale.
Why “100% AI” sites have plummeted
Successive algorithm updates, particularly those dedicated to “useful content”, have hit hard sites that published large volumes of automated texts that were not reworked. The trade press, which returned to the subject in mid-July, converges on the same finding: it is the lack of proofreading, proprietary data and real expertise that reduce visibility, not the tool used. Several studies also estimate that a considerable share — close to half according to some analyses — of content published online would today be produced with the help of AI, especially among high-volume publishers. The issue therefore goes far beyond SEO and affects all of brands' communication and marketing.
Best practices before publishing
- Proofread and correct each text: numbers, names, dates, claims.
- Provide an added value: proprietary data, concrete examples, firsthand experience.
- Sign articles and carefully present authors.
- Avoid mass-producing content on topics you don't master.
- Cite verifiable and recent sources.
For companies that outsource their content, these criteria also become a selection framework for providers, as shown by developments in the B2B and consulting sector.
Frequently asked questions
Can Google detect a text written by AI?
Google does not announce an “AI detector”: it evaluates the quality, originality and usefulness of pages. However, its quality raters are trained to identify content produced in series without added value, often characteristic of unsupervised automatic generation.
Should you disclose that an article was written with AI?
Google's rules do not require any mandatory disclosure. However, transparency is recommended when it is relevant to the reader, and adding a byline and author biography remains a valued signal of trustworthiness.
Can a site lose traffic because of AI content?
Yes — if it publishes large volumes of texts without proofreading or value: it risks algorithmic downranking, or even a manual spam action. A measured use of AI, with human review and real added value, does not lead to any specific sanction.
