Will Google penalise AI-written content on your website?

Short answer: Google's published guidance doesn't ban AI-written content. It warns against publishing lots of pages that add nothing for readers, however they were made. That caveat carries a lot of weight, so let's go through it properly.

Google's guidance on generative AI content doesn't ban it. It says generative AI "can be particularly useful when researching a topic, and to add structure to original content." That's a fair description of what most small businesses want from it. A bit of help getting started. A tidier outline.

So the question isn't "did a machine touch this?" It's "did this page help the person who landed on it?"

That's the same question you'd ask about anything a freelancer or a junior colleague wrote for you.

Here's where the warning sits. Using generative AI tools "to generate many pages without adding value for users may violate Google's spam policy on scaled content abuse."

Read that again. The problem is the many pages, and the missing value. Not the tool.

Google's spam policies define scaled content abuse as "when many pages are generated for the primary purpose of manipulating search rankings and not helping users." And then comes the phrase that matters most: "no matter how it's created." A team of humans churning out thin pages for rankings is in the same boat as software doing it.

Google's guide to generative AI search gives "7 Tips for First-Time Homebuyers" as an example of commodity content: content based on common knowledge that typically adds little unique insight. Google contrasts it with non-commodity content that offers a unique point of view, such as a first-hand account.

A useful test, and it's my own rather than Google's: could a competitor's page swap in for yours without anyone noticing? If so, the page adds little, whoever wrote it.

There's a related warning too. Google says creating separate content for every possible variation of how people might search, primarily to manipulate rankings or AI responses, violates its scaled content abuse policy. So if you're tempted to write forty near-identical pages, one per town or per phrasing, that's the pattern to avoid.

Now the practical bit. Google puts it plainly: "generative models don't retrieve facts, but predict a likely sequence of words based on their training data." Because of that, the outputs "may contain inaccuracies (also known as hallucinations)."

Translation for a business owner: the tool predicts what sounds likely, which isn't the same as checking what's true. The sentence can read just as smoothly either way.

Google's advice is that it's "critical to manually factcheck and review all AI-generated content for accuracy and trustworthiness before publishing."

And this is the part people forget. That review also applies to metadata. Title elements. Meta descriptions. Structured data. Alternate text for images. It's easy to check the body copy carefully and then paste in a meta description nobody read. If the tool wrote it, check it.

For a small business, the stakes are concrete. A wrong opening time, a service you don't offer. Or a claim about your qualifications that doesn't hold up. Those are problems for your customers before they are problems for your rankings.

Google says that "sharing information about how a piece of content was created can help give your readers more context." Its helpful-content guidance also asks whether the use of automation is self-evident to visitors, and says AI disclosures are useful where someone might think "how was this created?"

My judgement: you don't need a banner on every page. But where a reader might reasonably wonder, a short line helps. A guide that gives advice people will act on is one example. Something like "drafted with AI assistance, checked and edited by [name]" does the job. It's honest, it's brief, and it tells the reader a real person stands behind it.

That's a suggestion, not a rule. Use your own sense of where a reader might be curious.

If you use AI to help write, here's a sensible routine. Treat it as a starting point rather than a guarantee of anything.

1. Add first-hand detail. Your own experience is the one thing a tool can't supply. What you've seen on jobs, and what customers keep asking you. That's the stuff you'd tell a friend. This is what makes a page non-commodity.
2. Fact-check everything. Names, figures, claims, dates, prices. Then the title, the meta description and the image alt text.
3. Cut anything unsourced. If you can't confirm a claim, remove it. A shorter page that's true beats a longer one that might not be.
4. Don't mass-produce near-duplicate pages. One strong page beats thirty thin ones. If two pages say nearly the same thing, merge them.
5. Keep a human owner for each page. One named person who read it, checked it, and would answer for it.
6. Consider a short note on how it was made. Where readers might wonder, say so plainly.

None of that is complicated. It's mostly the editing you'd do anyway.

A disclosure: Seracu, which publishes this blog, sells articles that are drafted with AI assistance and then fact-checked. So you can fairly ask whether we're biased on this subject, and weigh what we say accordingly.

Here's the point that holds either way. Whoever helps you write, you remain responsible for the page. A freelancer, an agency, a tool, a friend. It's your website, your name, your customers. That's my view rather than Google's, but it's hard to see how it could be otherwise.

That's why the human owner matters so much. The page either helps the person reading it or it doesn't, and you're the one who gets to make sure it does.

So, will Google penalise AI-written content on your small business website? Based on what Google has published, the stated concern isn't the tool. It's pages generated at scale that add nothing for users. Publishing things that turn out to be wrong is a separate risk, and it is your customers who feel it. Both are avoidable.

1. Pick your five most important pages and check each one for factual errors, including the title, meta description and image alt text.
2. Add one piece of first-hand detail to each: something only you would know.
3. Look for near-duplicate pages and decide which ones to merge or cut.
4. Put a named person against every page, and decide whether any of them need a short note on how they were made.
