Does Google Penalise AI Content? What to Check on Your Site

No, Google does not penalise content for being written with AI. Its guidance says appropriate use of AI is not against its rules. What it does act against is “scaled content abuse”: many pages made mainly to rank, adding little for readers, however they were produced. If a site publishes a lot of generic posts, AI written or not, they can be ranked lower in a spam or core update. The fix is to find the weak posts and edit, noindex or remove them.

What Google actually says

Google’s own words are clearer than most articles about them. In its guidance on AI-generated content, Google Search writes:

“Appropriate use of AI or automation is not against our guidelines. This means that it is not used to generate content primarily to manipulate search rankings, which is against our spam policies.”

The same post describes its focus as “the quality of content, rather than how content is produced”. The problem behaviour is defined in Google’s spam policies:

“Scaled content abuse is when many pages are generated for the primary purpose of manipulating search rankings and not helping users. This abusive practice is typically focused on creating large amounts of unoriginal content that provides little to no value to users, no matter how it’s created.”

The first example on Google’s list is using generative AI tools to generate many pages without adding value for users. The others include scraping and rewording other sites, and stitching content together from different pages. So the test is not “was AI involved?” It is “would this page exist if search engines did not?”

A spam update is not the same as a penalty

When people say “penalty” they usually mean one of two different things:

• A manual action. A person at Google has reviewed the site and found a policy breach. It appears in Search Console under Security & Manual Actions > Manual actions, names the problem, and can be appealed with a reconsideration request once fixed.
• An algorithmic change. During a spam or core update, Google’s automated systems rank some pages or sites lower. Nothing appears in Search Console and there is nothing to appeal. Rankings change only when the site improves and Google re-assesses it.

Check Manual actions first. If it says “No issues detected”, you are dealing with the second kind. Our post on spam updates vs manual actions goes deeper, and if you have not yet matched your drop to an update date, start with what to check when traffic drops after a Google update.

Audit your own posts

You cannot tell from the outside which posts Google has judged weak, but Search Console shows which ones nobody sees. This takes a spreadsheet and some honest reading.

1. List every published post. Use your XML sitemap (at /sitemap_index.xml with Rank Math or Yoast), or if you have WP-CLI:

   wp post list --post_type=post --post_status=publish --fields=ID,post_title,post_name,post_date --format=csv > posts.csv

2. Export performance by page. In Search Console, open Performance > Search results, set the date range to the last 3 months, open the Pages tab and use Export. Pages with no impressions at all will not appear in the export, which is useful: anything in your post list that is missing from the export had no impressions.
3. Join the two lists and mark each post with its clicks and impressions. Ignore posts published in the last 90 days or so; they have not had time to show.
4. Read every post with zero or near zero impressions and ask Google’s own questions from its helpful content self-assessment, such as: “Does the content provide original information, reporting, research, or analysis?” and “Does your content clearly demonstrate first-hand expertise and a depth of knowledge?”
5. Look for patterns across posts, not just one at a time. The same headings in the same order on every post, examples that start “imagine a business that…”, statistics with no source, and posts on topics your business does not actually work in are all signs of content made for volume.

Edit, noindex or remove

In Rank Math, you can noindex a single post from the Rank Math box in the editor: open the Advanced tab and tick No Index under Robots Meta. The post stays live at its address for anyone with the link; it just stops being shown in search results.

Be careful with deleting in bulk. A post with links from other sites or steady clicks is worth more than it looks in a spreadsheet, and a deleted page cannot be compared before and after.

How to add first-hand detail

Editing for “quality” usually means adding what a generic article cannot know. For a small business, that is things like:

• Screenshots of the actual screens you used, from your own site or a test site.
• The exact steps you followed, including the one that did not work the first time.
• Australian detail that applies to your customers: GST, local payment providers, Australia Post, consumer law.
• A named author who did the work, with a short line on what they do.
• Removing every statistic you cannot link to a real source.

Never fill the gap with invented examples or client stories. A plain, accurate post is better than a confident one that is made up.

Using AI without the risk

AI is fine for outlines, first drafts and tidying wording. The risk comes from publishing at volume without a person who knows the subject checking every claim and adding what only you know. Three habits keep you safe: publish less often and only on topics your business actually works in, have a person edit and approve every post before it goes live, and stop any tool from publishing automatically.

Google also suggests asking “Who, How, and Why” about each page. On the “How”, it says AI or automation disclosures are useful where someone might reasonably wonder how the content was created.

Frequently asked questions

Does Google penalise AI content?

Not for being AI written. Google’s guidance says appropriate use of AI is not against its guidelines. Content made mainly to manipulate rankings, at scale and without value for readers, is against its spam policies however it was produced.

Can Google tell if content was written by AI?

Google has not said it ranks pages by detecting AI. Its published guidance focuses on whether the content is helpful and original, not on how it was made. That is the part you can control.

How do I know if a spam update hit my site?

Check whether your traffic drop lines up with a spam update on the Google Search Status Dashboard, and check Manual actions in Search Console. A drop during the update with no manual action means automated systems re-ranked the site.

Should I delete my AI written posts?

Not automatically. Keep posts that get clicks, improve the ones on topics you know, and noindex or remove the ones that repeat other posts or have nothing to do with your business.

Do I need to say a post was written with AI?

Google suggests a disclosure where readers would reasonably wonder how a page was made. It is a recommendation for readers’ benefit, not a ranking requirement.
