Google Says Fact-Check AI Content: Blogger Checklist
Key Takeaway: Google did not ban AI content. It asked for one thing: a real person checks the facts first, including the small text that shows up in search results. A simple repeatable checklist covers all of it.
What exactly changed
The change is in Google Search Central's page called "Guidance on using generative AI content on your website." That page shows it was last updated on October 1, 2026. According to Search Engine Roundtable, the earlier version dated from October 2025.
The new wording explains why. Google says generative AI models do not look up facts. They predict a likely sequence of words based on their training, so the output can contain mistakes, often called hallucinations. That is why Google now calls manual fact-checking and review of all AI-generated content critical before publishing. Google also said it updated the page to match what it tells people at its developer events.
What did not change
Two things stayed the same, and they are worth remembering so you do not panic.
- AI is still allowed. Google says generative AI can be useful for researching a topic and for adding structure to your own original content.
- The real danger is volume without value. Using AI to generate many pages without adding value for readers may break Google's spam policy on scaled content abuse. That rule has not moved.
So the message is not "stop using AI." It is "be the editor."
The part most people will miss: your metadata
Here is the detail I think matters most for Blogger writers. Google says the review also applies to metadata that can appear in search results. That means:
- Your title (the title element)
- Your meta description (in Blogger, the "Search description" box)
- Your structured data, if you add any to your template or posts
- The alt text on your images
Many of us let AI write these little fields in a hurry. A made-up number in a meta description, or an alt text that describes an image that is not really there, is exactly the sort of small mistake this guidance is talking about. These are the first things a reader sees, so they are worth thirty seconds each.
Is this connected to the September spam update?
It is natural to wonder. Google's September 2026 spam update began on September 24, and a second phase was reported on September 30. The doc change arrived right after. Search Engine Roundtable noted that Google rarely uses a word like "critical" in this documentation, and wondered whether the two are related.
The honest answer is that nobody outside Google knows. Google has not said the spam update targets AI content or that the guidance change is linked to it, so I would not build a panic plan around a guess. If your traffic dropped, I walked through how to check in my guide to what to do after the September 2026 spam update, and the earlier June 2026 spam update explained shows how to tell a spam update from a normal ranking dip.
The 10-minute fact-check checklist
Run this on every AI-assisted post before publishing. Most posts take about ten minutes once it becomes a habit.
| Check | What to look for | Time |
|---|---|---|
| Numbers, dates and prices | Every figure has a source you actually opened. Delete any number you cannot confirm. | 2 min |
| Names | Tools, features, companies and people are real and spelled right. AI sometimes invents plausible tool names. | 1 min |
| Policy and threshold claims | AdSense, YouTube or Google rules are matched against the official help page, not memory. | 2 min |
| Links | Each link opens, is relevant, and supports the sentence it sits in. | 1 min |
| Quotes | Anything in quotation marks is real and credited to the right source. | 1 min |
| Steps and menu paths | You have tried them yourself, or you say clearly that you have not. | 1 min |
| Title and search description | No claim in them that the post does not back up. | 1 min |
| Image alt text | It honestly describes the picture. | 1 min |
Where to find the metadata fields in Blogger
In the Blogger post editor, open Post settings in the right sidebar and look for Search description. For alt text, click an image in your post and open its properties to find the alt text box. Menu names can shift a little, so check them against your own dashboard.
Red flags AI tends to leave behind
When you read a draft, slow down at these spots. They are where hallucinations hide:
- Statistics with no source, like "studies show 73% of bloggers..."
- Old thresholds stated as if they are current, such as monetization requirements that changed since the model was trained
- Confident menu paths that do not match what you see on screen
- Phrases like "as an AI" or generic openings that say nothing
- Smooth, correct-sounding advice with no personal detail or real example
Add a short note about how the post was made
Google's page also has a section about giving readers context. It suggests that if you used automation, you consider explaining how, in a way that makes sense for your audience. A short, honest line at the end of a post is enough. For example:
Pro Tip: "I used an AI tool to help outline this post. I checked every figure against the official sources linked above and tested the steps myself." Say only what is true for that post, and change the wording each time.
A simple workflow you can reuse
- Use AI for research notes and structure, not as the final voice.
- Open the primary source for every fact (the official help page, the IRS page, the company announcement).
- Rewrite in your own words and add something only you have: your own test, screenshot or example.
- Run the checklist above, including the title, search description and alt text.
- Publish, then re-check the post in about a month if it covers anything that changes quickly.
What about your older posts?
If you have older AI-assisted posts, you do not need to fix everything in one weekend. Start with the pages that bring you clicks, which you can find in Search Console, and fact-check those first. Fix wrong numbers, remove claims you cannot support, and update anything that is out of date.
Final thoughts
This change can feel like one more rule to worry about, but it is really a gentle reminder of something you already know: readers trust a page when the facts are right. A ten-minute check is a small price for that trust, and it protects your AdSense income over the long run too. Take it one post at a time.

Google has not stated that the spam update or any ranking change is connected to this guidance change. Blogger menu names may differ slightly on your dashboard. This is general information, not a guarantee about rankings.
