How can I spot low-quality AI-generated website content?

AI itself is not the test

Generative AI can be useful for research, structure, drafting and other parts of a professional content workflow. Google does not ban a page simply because AI was involved. Its published guidance focuses on the quality, purpose and usefulness of the finished content rather than treating the production method as an automatic problem.

That distinction matters. A carefully reviewed page that uses modern tools can be far better than weak copy written entirely by a human. Equally, generating hundreds of pages does not make them useful just because the process was fast.

Look for signs of low-quality output

The most useful warning signs are signs that nobody with real knowledge of the business has taken responsibility for the page:

• copy so generic it could be pasted onto almost any competitor's website;
• the same phrases and sentence patterns repeated across several pages;
• strange wording, contradictions or claims that do not sound like the business;
• services, accreditations, locations or guarantees that the company does not actually offer;
• paragraphs that use plenty of words but never give the customer a useful answer;
• near-identical service or town pages where only one keyword or place name changes;
• testimonials that sound invented or cannot be connected to genuine customer feedback;
• headings written almost entirely around search phrases rather than customer questions;
• generic stock imagery everywhere, with no evidence of real projects, people or workmanship;
• content that shows no first-hand understanding of how the service is actually delivered.

None of those signs proves that AI was used. Human-written content can have exactly the same faults. The point is to recognise low-quality output, not conduct an AI forensic investigation.

Do not treat AI detectors as proof

Third-party AI detectors can produce false positives and false negatives. A score from one of those tools should not be treated as evidence that a particular person or company used AI. If you are reviewing website content, you will learn far more by checking the facts, asking whether the page says anything specific, and comparing the claims with the real business.

What Google actually says

Google's current guidance says generative AI can be useful, including for researching a topic and adding structure to original content. It also says that using generative AI or similar tools to create many pages without adding value may violate its scaled content abuse policy. That policy is about producing content at scale primarily to manipulate rankings rather than help users, regardless of whether the pages were produced by AI, automation or people.

Google's 2026 guidance goes further on quality: it recommends valuable, unique, non-commodity content, including material shaped by genuine experience or a distinctive point of view rather than information that simply recycles what is already everywhere else.

What good website content looks like

A strong service page should sound as though it belongs to that business. It should accurately describe what the company does, use the language customers actually understand, reflect genuine service areas, and answer the questions that matter before someone makes contact.

Good content also needs judgement. Facts should be checked. Claims should be defensible. Repetition should be edited out. The page structure should make sense for a human reader, not just a list of keywords. Real project details, appropriate photography and first-hand knowledge can add something a generic summary cannot.
