Does Google penalise AI-written content? What the rules actually say
Google doesn’t ban AI content, but it does act against low-value pages made at scale. Here’s what its guidance says, and how to stay on the right side of it.
It’s one of the most common questions from bloggers and small-business owners right now: if I use ChatGPT, Claude or Gemini to help write my pages, will Google punish my site?
The short answer is no, not for using AI. The longer answer matters more, because Google does take action against the kind of content that AI makes very easy to produce.
What Google has said
In February 2023 Google published guidance on AI-generated content in its Search Central blog. The core message was simple: Google rewards helpful, high-quality content however it is produced. Using automation or AI is not against its guidelines by itself.
What is against the guidelines is using any method, AI or human, mainly to manipulate rankings. In March 2024 Google strengthened its spam policies with a rule called scaled content abuse: producing large numbers of pages primarily to rank in search rather than to help people. The policy explicitly applies whether the pages are made by AI, by people, or by a mix of both.
So the line isn’t “AI vs human”. It’s “helpful vs mass-produced filler”.
Why AI content often struggles anyway
Even without a penalty, a lot of AI-written content performs poorly. The usual reasons:
- It says what everyone else says. AI models are trained on existing pages, so their drafts tend to repeat the most common points. If your article adds nothing new, there’s little reason for Google to rank it above the sources it echoes.
- No first-hand experience. Google’s quality guidelines added an extra “E” for Experience to E-A-T in December 2022. Details that only come from actually doing something, like a real price you paid or a problem you hit, are exactly what AI can’t invent honestly.
- Recognisable filler. Phrases like “in today’s fast-paced digital landscape” or “it’s important to note that” pad a page without adding meaning. Readers notice, and they leave.
- Errors. AI tools can state wrong facts confidently. A single invented spec or statistic can damage trust in the whole page.
How to use AI safely
AI is a genuinely useful writing assistant. These habits keep it working for your site:
- Start with your own angle. Decide what you know or have tested that others haven’t written about, and give AI that outline rather than a bare keyword.
- Treat the output as a first draft. Rewrite the introduction and conclusion in your own words, and add at least one example from your own experience.
- Check every fact. Prices, dates, specifications and quotes should be verified against the original source.
- Cut the filler. Delete stock transitions and repeated points. Shorter and clearer usually wins.
- Publish less, but better. Ten genuinely useful pages beat a hundred thin ones, both for readers and for Google’s spam systems.
A quick self-check before publishing
Paste your draft into the Writing Pattern Indicator to spot overused AI-style phrases and flat, same-length sentences. Then run it through the Readability Checker to make sure it’s easy to read. Neither tool can tell you who wrote something, and nothing reliably can, but both point at the patterns that make writing feel generic.
The question Google asks isn’t “was this written by AI?” It’s “would a reader be glad they found this page?”
If the honest answer is yes, the tool you used to help write it doesn’t matter.
