There is no Google AI content penalty for using AI to write. There is a penalty for publishing thin, low-value pages, and a lot of AI-assisted content trips that wire because it says nothing a reader couldn't already guess. If your rankings have slipped after you started pumping out AI drafts, the tool isn't the problem. The lack of real substance is.
Google has been clear on this. Its guidance says it rewards helpful, reliable content made for people, however it's produced. So an AI-written page can rank fine if it's genuinely useful. The trouble is most AI output, published as-is, is generic. Same phrasing, same structure, same surface-level points as ten thousand other pages. Google's systems are built to spot exactly that.
What Google actually treats as thin
Thin content isn't about word count. You can have 2,000 words and still be thin. It's about whether the page adds anything the reader can't get elsewhere. Google's helpful content system asks a simple question. Does this page satisfy the person who landed on it, or does it just fill space around some keywords.
AI content gets flagged when it does the following:
- Restates the obvious with no first-hand experience or opinion.
- Covers a topic broadly but answers no specific question well.
- Reads like it was written to hit a keyword rather than help a human.
- Has no author, no expertise, no reason to trust it.
- Repeats what the top ten results already say, in slightly different words.
None of that is unique to AI. Bad human writing does it too. But AI makes it fast and cheap to produce at scale, which is why so many sites have quietly filled up with pages that drag the whole domain down.
The real cost of thin pages
It isn't just that the weak pages don't rank. They can hurt the pages that would have. When a chunk of your site looks low-value, Google's assessment of the whole site can drop. Your good pages, the ones you worked hard on, get pulled down with the dead weight.
Then there's the cost to the reader. Someone finds your page, reads two paragraphs of fluff, sees nothing that helps, and leaves. That's a customer you paid to attract with your content effort, gone in seconds, with a worse impression of your business than before they arrived.
After 19 years running businesses, Luke Stillwell will tell you the same thing about content that applies to everything else. If it doesn't do a job for the person in front of you, it's a cost, not an asset.
How to audit your AI-assisted pages
You don't need to delete everything and start over. You need to find the pages pulling their weight and fix or cut the rest. Here's how.
1. List every page and check the traffic
Pull your pages from Google Search Console. Sort by clicks and impressions. Pages with impressions but almost no clicks are being shown and ignored, which is often a thin-content signal. Pages with neither are candidates to improve or remove.
2. Read each weak page as a customer, not the author
Ask one honest question. If a real prospect read this, would they know more, trust you more, or be closer to buying. If the answer is no, it's thin, whoever or whatever wrote it.
3. Add what only you can add
This is where AI can't compete and you win. Put in the things a machine doesn't have. Your experience of the job. The mistake clients make that you fix. The specific answer to the question people actually ask you on the phone. That's the value that turns a generic page into one worth ranking.
4. Merge, improve or remove
Two thin pages on nearly the same topic should usually become one strong page. A page you can't make useful should be removed or set to noindex. Fewer, stronger pages beat a pile of filler every time.
Using AI without triggering the thin-content signal
Keep using AI. Just don't publish its first draft. Treat it as a fast assistant, not the writer. Get it to structure ideas, then bring the substance yourself. Add your voice, your examples, a clear answer to a real question, and a reason for the reader to trust the source.
This is exactly the approach we take with content at 07 Heaven Marketing. Content that reads like a person who knows the subject wrote it, because someone who understands it did the important part. Pair that with solid SEO and a well-built website underneath, and your pages earn rankings instead of gambling on them.

07 Heaven Marketing helps SME owners turn thin pages into ones that actually bring in customers. The fix is rarely more content. It's better content.
Common questions
Does Google penalise AI-generated content?
Not for being AI-generated. Google rewards helpful content however it's made and demotes thin, unhelpful content whoever made it. The issue is that unedited AI output is usually generic, which is what gets flagged.
How do I know if my content is considered thin?
Check Google Search Console for pages with impressions but few clicks, then read them as a customer. If a page adds nothing beyond the obvious and gives no reason to trust it, Google likely sees it as thin too.
Should I delete my AI-written pages?
Only the ones you can't make useful. Improve the pages worth saving by adding real experience and clear answers, merge near-duplicates, and remove or noindex the rest.
