Google’s September 2026 Spam Update: What Local Business Websites Should Check Now

Most spam updates come and go without small business owners noticing. This one is different for two reasons. It is rolling out over two weeks instead of a couple of days, so the impact keeps arriving in waves. And it landed at the same time Google changed its advice on AI-written content, at a moment when many local businesses are using AI tools to fill their blogs and service pages. This guide explains what changed, who is most at risk, and what to check on your own site this week.

What Google actually announced

On September 24, 2026, Google posted this on its Search Status Dashboard: “Released the September 2026 spam update, which applies globally and to all languages. The rollout may take up to two weeks to complete.” Search Engine Roundtable noted this is the fourth spam update of 2026 and the first this year with such a long rollout.

On October 1, Search Engine Roundtable reported a second wave on September 30, after a first wave on September 25 to 27. SEO consultant Glenn Gabe said he heard from several site owners who saw a big drop on 9/30. As of that report, the rollout was not complete, so more movement is possible until Google marks it finished on the dashboard.

The AI content guidance change

The same week, Google updated its guidance on using generative AI content. The new wording says: “It is critical to manually factcheck and review all AI-generated content.” Google explains that AI tools predict words rather than look up facts, so their output can contain made-up details. Search Engine Roundtable pointed out that “critical” is a strong word for a Google help page.

To be clear, Google has not said the two changes are linked. Google still allows AI-assisted content. What it does not allow is using automation to publish large amounts of low-value pages mainly to rank. For a local business, the practical takeaway is the same either way: every page on your site should be checked by a person who knows your trade.

Which local business sites are most at risk

Spam updates target pages that break Google’s spam policies. Most honest small business sites are fine. These are the patterns we see most often on local sites that get into trouble:

How to tell if the update hit your site

Do not judge by one bad day. Rankings move for many reasons, including competitors and normal seasonality. Look for a clear drop that lines up with the update dates.

• Open Google Search Console, go to Performance, and compare clicks and impressions from September 24 onward with the weeks before
• Check whether the drop is site-wide or limited to certain pages, such as city pages or blog posts
• Look at the Manual actions report in Search Console. A manual action is different from an algorithmic update and comes with a message
• Compare your Business Profile calls and direction requests for the same period, to see whether real leads changed or just impressions
• Note the dates in a simple log so you can match future changes to future updates

If you see no drop, you do not need to make big changes because of this update. Keep building useful pages. If you are not sure how to read the numbers, our technical SEO service includes a Search Console review.

What to do if you were hit

Google’s own advice for spam updates is to review its spam policies and make sure your site follows them. There is no quick fix and no button to ask for a re-check after an algorithmic spam update. Google has said improvements can take many months to be reflected. Here is the order we would work in:

1. Wait for the rollout to finish before big changes

The update was still rolling out at the start of October. Making large changes mid-rollout makes it hard to know what helped. Use the time to audit, then act once Google marks the update complete.

2. Merge or rewrite thin city pages

Keep a city page only if you can say something real about that area: jobs you have done there, local conditions, response times, photos from real projects. Merge the rest into a strong service page or a single service area page. Our locations hub shows how we structure area pages with distinct content.

3. Put a person back in charge of AI content

Go through every AI-assisted post. Check prices, permit rules, product names and any claims for accuracy. Add what only your business knows: your process, common mistakes you see on jobs, real photos. Delete posts that add nothing. This matches Google’s new advice to manually factcheck and review AI content.

4. Clean up keyword stuffing and hidden text

Remove long city lists from footers, repeated keyword phrases and any hidden text. Write for the customer reading the page. Our on-page SEO service covers this kind of cleanup.

5. Review your links

If you or a past agency bought links, list them and stop any ongoing link deals. Focus on earning real local mentions instead, like suppliers, local associations and community sponsorships.

How to protect your site going forward

The safest local SEO is boring in a good way. Publish fewer pages, make each one useful, and make sure a real person who knows the work has checked it. A plumber’s page about water heater repair should read like it came from someone who has replaced water heaters, not from a template. That kind of content holds up through spam updates and also gives AI search tools something trustworthy to cite.

Frequently asked questions

Does the Google spam update affect my Google Maps ranking?

The spam update is about web search results. Your Business Profile listing is handled separately, but your website still supports your local visibility, so a big website drop is worth fixing.

Is using AI to write my website content against Google’s rules?

No. Google allows AI-assisted content. The problem is publishing lots of unreviewed, low-value pages mainly to rank. Google now says it is critical to manually factcheck and review AI-generated content before publishing.

How long does recovery from a spam update take?

There is no fixed timeline. Google has said it can take many months for its systems to learn that a site now follows its spam policies.

How do I know when the update is finished?

Google marks updates as complete on its Search Status Dashboard. Until then, rankings may keep moving.

Can I file a reconsideration request?

Only for a manual action, which appears in the Manual actions report in Search Console. An algorithmic drop from a spam update has no reconsideration request. You fix the site and wait.
