Google Spam Update: What It Targets and How to Tell If You Were Hit

A Google spam update is a notable improvement to Google’s automated spam detection, announced on the Google Search Status Dashboard. It targets pages that break Google’s spam policies, such as scaled content abuse, expired domain abuse, site reputation abuse and link spam. If your site complies, a spam update should leave you alone. If it doesn’t, pages can rank lower or drop out of results entirely.

The most recent one is the September 2026 spam update, which began on 24 September 2026. As of 30 September 2026, the dashboard still shows no completion message for it.

I get the same panicked question after every one of these: “Did the spam update hit me?” Often the honest answer is no. The traffic drop came from something else entirely. So this post gives you the dates, explains what each update goes after, and then walks you through a short decision path to find out whether spam is really your problem.

What Is a Google Spam Update?

Google’s systems scan for spam all the time. Most of the time you never hear about it. Every so often, though, Google makes a notable improvement to those systems, and that’s when it announces a spam update.

Google’s own spam updates documentation says this plainly: when it makes such an improvement, “we refer to this as a spam update,” and it lists them on its ranking updates page. The same page names SpamBrain, which Google describes as its AI-based spam-prevention system.

The part I want every site owner to read twice is the recovery line. Google says “making changes may help a site improve if our automated systems learn over a period of months that the site complies with our spam policies.” Months. Not days after you delete a few pages.

How Is a Spam Update Different From a Core Update?

People mix these two up constantly, and it leads to the wrong fix. A core update re-ranks the whole web. A spam update removes or demotes content that breaks specific rules.

Google’s core updates page says core updates “don’t target specific sites or individual web pages.” It even compares them to reshuffling a list of favorite restaurants, where the ones that move down “aren’t necessarily bad.”

A spam update is the opposite in spirit. If your traffic fell during one and you can match the drop to a policy, the cause is probably something on your site. That’s uncomfortable, but it also means you have something concrete to fix.

Every Google Spam Update Since 2024

Here is every spam update listed on the Google Search Status Dashboard from March 2024 onward. I checked each entry on 30 September 2026. Rollout length is the duration the dashboard shows.

Notice the March 2026 spam update ended on 25 March and the March 2026 core update started on 27 March. When two updates land that close together, I don’t trust anyone who claims to know which one moved their traffic. Look at what kind of pages dropped instead.

For the September 2026 update, Google’s message says it “applies globally and to all languages” and may take up to two weeks. So if you’re reading this in early October, give it time to finish before you judge anything.

What Do Spam Updates Actually Target?

Spam updates enforce Google’s spam policies. The list is long: cloaking, doorway abuse, hidden text, keyword stuffing, link spam, scraping, sneaky redirects, thin affiliation, user-generated spam and more. Three policies from March 2024 cause most of the confusion I see, so I’ll spend my time there.

Scaled Content Abuse

Google announced this policy on 5 March 2024, in its post about the March 2024 core update and new spam policies. The current definition: “many pages are generated for the primary purpose of manipulating search rankings and not helping users.”

The key detail is that Google doesn’t care how the pages were made. The 2024 post says it applies “whether automation or humans are involved.” So a farm of hand-written thin pages is just as exposed as a pile of AI output. What matters is the purpose and the value.

Site Reputation Abuse

This one targets third-party content hosted on a strong site to borrow that site’s ranking signals. Google’s examples include an educational site hosting third-party sponsored reviews of payday loans. Press release services, syndicated news and normal forums or comment sections are not violations.

Two things changed since 2024, and a lot of articles still miss them. First, the section now carries the heading “site reputation policy” on Google’s spam policies page (last updated 28 August 2026). Second, the consequence now depends on where searchers are. Outside the European Economic Area, pages may get a manual action. Inside the EEA, Google says the pages may be treated as separate from the main domain instead of getting a manual action.

When it launched, Google gave site owners until 5 May 2024 to prepare. That enforcement date still gets quoted as if it were news. It isn’t.

Expired Domain Abuse

Google defines it as an expired domain that “is purchased and repurposed primarily to manipulate search rankings by hosting content that provides little to no value to users.” The 2024 post gives the example of an old medical domain turned into a low-quality casino site.

Buying an old domain is not the problem. Google’s own post says it’s fine to use an old domain “for a new, original site that’s designed to serve people first.” The abuse is riding the old reputation with junk.

Link Spam and Hacked Content

Link spam gets its own updates, and Google’s note about it is blunt. After a link spam update, “making changes might not generate an improvement,” because any ranking benefit the spammy links gave you is simply gone. I cover where the line sits in white hat vs black hat link building, and whether you should worry about bad links pointing at you in toxic backlinks.

If Google is showing spam pages on your domain that you never created, that’s a hack, not a spam update. Go to my guide on WordPress SEO spam for that.

How Do You Know If a Google Spam Update Hit Your Site?

Four variables decide the answer, and I check them in this order:

1. Timing. Did the drop start inside the rollout window, or within a few days of it?
2. Manual action. Does the Manual Actions report in Search Console show anything?
3. Pattern. Did one section or page type fall, or the whole site?
4. Policy match. Can you point at pages that plausibly break a named policy?

Start with dates. Google’s guide to debugging drops in Search traffic suggests setting the Performance report to the last 16 months first, so you can rule out seasonality. Then use the compare feature, for example the last 3 months against the previous period. For an update, I compare the week after rollout finished with the week before it started, which is the same approach Google recommends for core updates.

Then open the Pages tab. If the losses cluster in one folder, one template or one type of page, write that down. That pattern is your best clue.

If Search Console Shows a Manual Action

If the Manual Actions report lists an issue, then you’re dealing with a human reviewer’s decision, not just an algorithm. Google’s help page describes a manual action as what happens “when a human reviewer at Google has determined that pages on the site are not compliant” with its spam policies.

This is the clearest branch, oddly. The report tells you the issue type and the affected pages. Fix every instance, then click Request Review and explain what you changed. Google says most reviews take several days or weeks, and link-related ones can take longer.

If There’s No Manual Action but the Timing Matches

If the report is clean, the drop lines up with a spam update, and you can match the lost pages to a policy, then it’s most likely algorithmic. There’s nothing to submit. You fix the practice and wait for Google’s systems to notice, which Google itself says happens over months.

I’d be honest with yourself here. Did you publish hundreds of near-identical location pages? Rent out a subfolder to a coupon partner? Buy links? Those are the usual culprits.

If the Timing Doesn’t Match or You Can’t Find a Policy Breach

If your pages look compliant, then stop blaming the spam update. Look for a core update, a technical fault, a lost snippet or plain seasonality. My monthly SEO report guide has a section on explaining a traffic drop that walks through those other causes.

Decision Matrix: Spam Update or Something Else?

How Do You Recover After a Spam Update?

Recovery is mostly about removing the cause and being patient. Here’s the order I follow:

1. Wait for the rollout to finish. Check the dashboard for the “rollout was complete” message, then give it about a week.
2. Map the lost pages to a policy. Write down which policy each group of pages breaks. If you can’t name one, go back to the decision matrix.
3. Remove or fix the violating practice. Take down the scaled pages, end the third-party arrangement, or stop the link buying. Improve what’s worth keeping.
4. Clean up the fallout. Update internal links, and return a proper 404 or 410 for pages you removed.
5. Handle manual actions separately. Only a manual action gets a reconsideration request.
6. Track and wait. Compare the same periods month over month. Don’t judge it in two weeks.

A word on deleting things. For removed spam, deletion is the right move. For merely weak content, it usually isn’t, and Google’s core updates page calls deleting content “a last resort.” My guide to content pruning covers how to decide page by page.

When Should You Get Expert Help?

A small blog with one obvious problem can handle this alone. I’d bring in an experienced SEO when you have a manual action you don’t understand, when a large share of the site dropped at once, or when the drop overlaps a core update and you can’t separate the two.

That untangling is what we do in our SEO recovery service. If you’d rather start with a second opinion, request a free SEO audit and I’ll tell you whether I think spam is really the cause.

Frequently Asked Questions

When Was the Last Google Spam Update?

The latest is the September 2026 spam update, which started on 24 September 2026. Google said it may take up to two weeks to roll out. As of 30 September 2026, the Search Status Dashboard had not posted a completion message. The previous one, the August 2026 spam update, finished on 21 August 2026.

How Long Does It Take to Recover From a Spam Update?

Google says a site may improve if its automated systems “learn over a period of months” that the site complies. So plan in months. For link spam, Google warns that fixing things might not bring rankings back, because the benefit those links gave you is lost for good.

Can a Spam Update Hit a Site That Did Nothing Wrong?

Spam updates aim at policy violations, so a compliant site shouldn’t be the target. But a drop can still coincide with one. That’s why I check the Manual Actions report, the page pattern and other updates before blaming spam.

Do I Need to File a Reconsideration Request After a Spam Update?

Only if Search Console shows a manual action. Algorithmic demotions have nothing to submit. You remove the violating practice and let Google’s systems re-evaluate the site over time.
