Google Spam Update Explained: The August Rollout, Manual Actions and How to Stay Safe

A Google spam update is an improvement to the automated systems that detect sites breaking Google's spam policies, and each rollout can push some sites sharply down the results. The August rollout, for example, finished within days. Then the September rollout started. In this guide I cover both, using official sources only.

I have worked with search results since 2012, and every spam wave brings the same panic: traffic drops, people blame the core update, and nobody checks the actual cause. So this guide walks you through diagnosis, manual actions, reconsideration requests and the habits that keep a site safe. Keep the SEO checker open while you review your own pages.

What is a Google spam update?

A Google spam update is a notable improvement to the automated systems Google uses to find pages that violate its spam policies. The best known of these systems is SpamBrain, an AI based spam prevention system. Once the update goes live, violating pages can rank lower or disappear from results entirely.

One detail matters from the start: a spam update does not create new rules. The rules already live on the spam policies page. The update simply makes Google better at catching what those rules describe. Therefore the useful question is not "what did the update ban?" but "what on my site breaks the policies?"

Google announces each rollout on the Search Status Dashboard. The dashboard shows the start time, the scope and the completion note. That is why I always take dates and durations from there. Forum rumours and social posts make a weak foundation for any diagnosis.

What happened in the August Google spam update?

According to the Search Status Dashboard, the August rollout began on 18 August at around 09:27 Pacific time. In its first note, Google said the update applies globally and to all languages. It also said the rollout might take a few days.

The completion note arrived on 21 August, and the dashboard lists a total duration of 2 days and 16 hours. It was also the third spam wave of the year. The earlier two started on 24 March and 24 June. The March rollout took about 19.5 hours, while the June rollout took about two days.

Google did not publish a separate blog post or a new policy alongside the August rollout. In other words, it enforced existing rules more effectively. For comparison, the previous year's August spam update lasted 26 days and 15 hours. Shorter rollouts mean that an affected site now sees a clear drop within a few days instead of a slow slide over several weeks.

That said, "all languages" really means all of them. A small local shop and a large publisher face the same automated checks, and site size gives no protection.

Why did the September rollout follow so quickly?

On 24 September, Google started the September spam update. The dashboard note again mentions global scope and all languages. This time, however, it says the rollout may take up to two weeks. As of 30 September, when I am writing this, there is no completion note yet.

The gap between the two rollouts is a little over five weeks. Google does not explain why updates arrive at this pace, so I will not speculate. The practical point is simple: a site that survived August is not automatically safe in September. After all, each wave may teach the system to catch a different tactic.

My advice is straightforward. Avoid major site changes while a rollout is running. Next, wait for the completion note and measure the effect a few days later. Otherwise you cannot separate the impact of your own changes from the impact of the update. Meanwhile, keep watching daily data; the impression curve of your ten strongest pages usually gives the earliest warning.

How does a spam update differ from a core update?

People mix these two types up all the time. However, the diagnosis and the fix are completely different. A core update recalibrates the systems that judge overall content quality and relevance. A spam update, on the other hand, targets tactics that break the rules. The table below sums up the difference:

This year Google ran core updates in March and May, and both lasted around 12 days. So matching the date of your drop against dashboard entries is always the first step. When a spam rollout and a core rollout overlap in the same week, compare page groups instead of the whole site.

How does SpamBrain work, and what does it catch?

Google describes SpamBrain as its AI based spam prevention system. The official spam updates page says Google keeps improving it to spot new types of spam. What we call a spam update is often the release of such improvements.

There is no detailed technical document on how SpamBrain works internally. For that reason, treat any article that claims to know "the exact signal" with caution. What we do know is that the system looks at both spammy pages and spammy links. On the link side, Google states that once its systems remove the effect of spammy links, any ranking benefit those links gave your site is gone.

This sentence matters because many site owners believe they have a penalty. In practice, they often just lose artificial strength. You can lose rankings without any penalty at all. Moreover, this loss is not a sanction you can appeal; it is the removal of support the site never deserved.

Which practices do Google's spam policies cover?

Google last revised the spam policies page on 28 August. I group its headings into three buckets, because that grouping makes audits faster:

• Content: scaled content abuse, scraping, thin affiliation, keyword stuffing, hidden text and link abuse.
• Technical: cloaking, sneaky redirects, doorway abuse, hacked content, malicious practices, misleading functionality.
• Authority: link spam, expired domain abuse, the site reputation policy, user generated spam, machine generated traffic.

At the end of the page there is also a section on other practices that can lead to demotion or removal. It covers legal removals, personal information removals, policy circumvention, and scam and fraud. For example, Google says that a high volume of valid copyright removal requests against a site can lead it to demote other content from that site too.

In short, the list is long, but the common thread is one idea: misleading users or search systems.

How can scaled content abuse hurt your site?

This is the violation I have seen most in the past two years. Google's definition is clear: producing many pages mainly to manipulate rankings, without helping users. Whether you do this with AI, scraping or human writers makes no difference.

The examples on the policy page are concrete. One is using generative AI tools to create many pages without adding value for users. Another is scraping feeds or search results and multiplying pages through synonym swaps, translation or similar transformations. Stitching unrelated text together just to include keywords also counts.

In practice, the warning signs look like this: hundreds of city pages with the same service copy, thousands of template "what is X" posts, and comparisons with no original data or experience. So question why each page exists, not how many pages you have. When writing, the principles in how to write SEO friendly content and the E-E-A-T trust criteria give you a solid framework.

What changed in the site reputation policy in August?

On 28 August, Google published a Search Central blog post about the site reputation policy. The policy targets third party content that appears on a trusted site mainly to exploit that site's ranking signals. A typical case is a news site hosting unrelated coupon or casino pages in a subfolder.

The change followed discussions with the European Commission. Since 30 August, manual actions under this policy have a different effect inside and outside the European Economic Area. For searchers outside the EEA, the affected section drops directly. For searchers inside the EEA, the manual action does not apply; instead, the affected section may over time rank independently from the rest of the site.

So the practical impact depends on where your audience searches. If you serve both the UK and Germany, for instance, you may see different behaviour in each market. Notifications still arrive through Search Console. Eligible sites can also take disputes to mediation after a reconsideration request.

Why is back button hijacking a new risk?

On 13 April, Google declared back button hijacking an explicit violation of its malicious practices policy. Enforcement then started on 15 June. The definition is simple: if users cannot return to the page they came from when they press back, the site interferes with browser history.

I highlight this point because most site owners do not do it on purpose. According to Google's own note, some cases come from libraries or advertising platforms that a site includes. In other words, an ad plugin can insert fake history entries without your knowledge.

You can test it yourself. First, reach your site from Google search, browse a few pages, then press back. If you land on an unexpected interstitial or ad, find the script responsible and remove it. Test on mobile browsers in particular, because problems tend to show up there first. This violation can lead to manual actions and to automated demotions.

Why do paid links no longer help?

Link spam covers buying links, excessive link exchanges, automated link building and mass submissions to low quality directories, among other tactics. Still, Google's stance here has not changed for years. What has changed is its ability to detect these links.

Let me return to the earlier point: once spammy links lose their effect, the advantage they gave disappears too. That is why a site that climbed on paid links often falls back to its "real" position after a spam update. Calling this a penalty is misleading; the ranking was never earned in the first place.

For a healthy link profile, start by seeing what you actually have. My article on backlink quality explains which links carry value. Also review outgoing links from your own pages; the broken link checker lists broken and suspicious external links quickly. Finally, mark sponsored links with rel="sponsored".

How do you tell a manual action from an algorithmic drop?

The distinction is simple but vital. With a manual action, a Google reviewer looks at your site and finds a policy violation. With an algorithmic drop, no human is involved; automated systems simply rank the site lower.

The only reliable way to confirm a manual action is the Manual actions report in Search Console. If the report is empty, a manual action did not cause your drop. If it lists an issue, Google states the violation and the affected area clearly, and you also receive a message in Search Console. For newcomers to the tool, my Google Search Console guide covers the basics.

One more change arrived this year. On 14 April, Google added to its documentation that it may use spam reports to take manual action. So a report from a competitor or a user no longer just trains systems; it can also trigger a direct review. That makes policy compliance even more important.

How do you diagnose a drop after a Google spam update?

Stay calm and work in order. This is the sequence I follow in every audit:

1. Find the day the drop began in the Search Console performance report and match it against dashboard dates.
2. Check the Manual actions report and the Security issues report.
3. Decide whether the drop affects the whole site or a specific folder; compare page groups.
4. Look for a shared pattern on affected pages: template content, paid links, redirect chains or ad code.
5. Check server logs to see whether Googlebot behaviour changed.
6. Write down the findings and prioritise the fix plan.

Tools speed up steps four and five. The log file analyzer shows crawl behaviour, and the redirect checker helps you rule out sneaky redirects. If the drop overlaps with more than one update, do not rush to a verdict. First, pin down which page group fell and when.

Which mistakes should you avoid during a spam rollout?

Decisions made in the first days after a drop often make things worse. These are the reflexes I see most in audits:

• Deleting or redirecting hundreds of pages at once while the rollout is still running.
• Buying a new link package to make up for the loss.
• Rewriting all content with AI and publishing it on the same day.
• Looking for a reconsideration form when there is no manual action.
• Rebuilding site architecture based on a single forum theory.

The common problem is treatment without diagnosis. Worse, some of these steps create a new violation; rushed link purchases, for example, can cause a second loss in the next wave. So measure first and change second. Also make changes in small batches and note the date of each batch. That way you can see later which step actually helped.

How do you prepare a reconsideration request after a manual action?

Google's Manual actions report help page describes the process clearly. The key sentence is this: fixing the issue on only some pages will not earn a partial return to search results. So do not send a request until the fix covers every affected page.

A good request explains three things. First, it describes the exact issue on your site. Second, it lists the steps you took to fix it. Finally, it documents the outcome of those steps. For a link related action, for instance, you can attach a list of removed links and your outreach records.

After the fix, make sure Google can access the pages: no login wall, no paywall and no robots.txt block. Next, test a few sample URLs with the URL Inspection tool. According to Google, most reviews take several days or weeks, although link related requests can take longer. You receive email updates throughout.

How long does recovery from a spam update take?

The honest answer: not quickly. Google says that changes may help a site improve if its automated systems learn over a period of months that the site complies with the spam policies. The word "months" comes from the official page, not from my estimate.

Manual actions work a little differently. Once Google accepts your request, the action disappears. Still, rankings may not return to their earlier level. Positions that paid links built will not come back, because the value of those links already reset to zero.

That is why I plan recovery on two layers. The first layer removes the violation. The second layer builds the site's own strength: original content, real references and natural links. Keeping content current also belongs here, as I explain in my piece on content freshness. During the waiting period, avoiding new violations matters as much as the cleanup itself.

Which checks protect you from the next Google spam update?

Regular audits are the cheapest protection. My team and I run this list on client sites every quarter:

• Review pages published in the last three months: does each one offer something new?
• Spot page groups that come from a single template and merge them where needed.
• Find unnatural repetition in titles and copy; a keyword density check helps here.
• List every third party script on the site: ads, chat, analytics plugins.
• Clean spam from comments and forum areas.
• Check the attributes on guest posts, sponsored content and outgoing links.
• Open the Manual actions and Security issues reports in Search Console.

This list is not glamorous, but it works. Most problems do not come from bad intent; they come from old decisions nobody revisited. Also, a regular audit shortens diagnosis time when the next spam wave arrives.

Why are expired domains and doorway pages risky?

Expired domain abuse means buying an old domain and filling it with unrelated, low value content mainly to exploit its past reputation. For example, a domain that once belonged to a charity suddenly hosting casino or product comparison pages fits this definition. Google therefore lists the tactic as spam.

That does not mean buying an old domain is forbidden. If you use it for a real brand with your own original content, there is no problem. The problem is exploiting the domain's past strength for a different purpose. So check the domain's history before you buy; the website history tool helps with that.

Doorway pages target similar searches and funnel users to a final destination. Service pages for every district with nearly identical copy are a typical example. Users find nothing new on them, so Google may treat them as doorways. If you create local pages, give each one genuine information specific to that area.

How can you spot cloaking and sneaky redirects?

Cloaking means showing different content to search engines and to users. A sneaky redirect sends users to a page other than the one search engines see. Site owners rarely do either on purpose; in my experience they usually point to a hacked site.

The symptoms tend to look like this: a page opens normally on desktop, but a click from Google on mobile leads somewhere else entirely. Alternatively, the content you see in the URL Inspection tool differs from what your browser shows. You can test this difference yourself.

A few steps are enough. First, run a live test on key pages in URL Inspection and compare the screenshot with your browser. Then open the pages from Google results on different devices. Finally, review redirect chains. If you find an unexpected destination, check your server configuration and the .htaccess file, and switch plugins off one by one to narrow down the source.

How do you prevent hacked content and user generated spam?

Two items on the policy list can happen outside your control: hacked content and user generated spam. Hacked content is code, pages or redirects that someone places on your site without permission through a security hole. Google sees it as both a danger to users and a ranking manipulation tool.

The foundation of protection is updated software, strong passwords and strict access rights. Specifically, old plugins and exposed admin panels are the most common entry points. For your technical team, the article on OWASP Top 10 vulnerabilities offers a practical checklist.

User generated spam arrives through comment sections, forums and profile pages. Set up moderation, add rel="ugc" to user links and filter automated sign ups. Also, if your site suddenly gains impressions for keywords you never targeted, treat that as an early warning. It is often the first sign of injected pages.

Does manipulating AI answers count as spam?

Yes. On 15 May, Google clarified in its documentation that the spam policies also apply to generative AI responses in Google Search. The introduction of the policy page now defines spam as techniques that deceive users or manipulate Search systems, including attempts to manipulate generative AI responses.

This means hidden instruction text, fake comparison pages or scaled "best of" lists built to appear in AI Overviews carry the same risk as classic spam. There are legitimate ways to show up in AI answers, and I cover them in my guide on writing content for AI Overviews.

In short, the rule has not changed; only its scope has widened. A tactic banned in classic results is banned in AI answers too.

How do my team and I run a spam audit?

When a site loses traffic after a spam wave, my team and I look at data first and form hypotheses second. On day one we bring together Search Console, dashboard dates and server logs. Next, we match affected page groups with violation types. Then we order the fix plan by impact and cost.

The biggest time saver is asking the right question. "Which update hit us?" is not enough on its own. "Which pages dropped, and because of which features?" leads to an answer. Seeing how competitors moved in the same period adds context too; for that we use the method in SEO competitor analysis.

If your site has seen a similar drop and you want an independent view, my team and I can run this audit with you as part of our SEO consulting. Our aim is not a quick rescue but a site that stays standing through the next update as well.

What is the safest long term strategy against spam updates?

My conclusion after many years is simple: the safest strategy is not to chase updates. Each new wave makes rule breaking tactics a little less effective. A site that stays within the rules is usually unaffected, and it often climbs as competitors fall.

So put your budget into lasting value rather than shortcuts. Content with real experience, naturally earned links, clean technical foundations and a safe user experience carry the lowest risk over time. Also build the habit of checking the Search Status Dashboard after every major wave.

When the September completion note arrives, measure the effect; if you see a drop, follow the diagnosis steps in this guide in order. Put simply, method beats panic every time. For the next Google spam update, use the same sequence: date, reports, page groups, and only then the fix.
