Google Spam Update, August 2026: Has Your Website Been Affected? Here’s How to Tell—and What to Do About It

On Monday morning, the business owner opens Search Console and can’t believe his eyes. Traffic from Google is down by a quarter over the weekend. Yet no one made any changes to the website; no one added content or modified the code. The only thing that happened was that he happened to wake up to a week when Google launched another spam crackdown.

Between August 18 and 21, 2026, the third anti-spam update targeting search results this year took place. For the vast majority of legitimate company websites and online stores, this is no cause for panic. Still, it’s worth knowing how to recognize a drop in traffic, what exactly Google has removed, and what to do if it affects you.

What Actually Happened Between August 18 and 21, 2026?

Between August 18 and 21, 2026, Google rolled out a so-called "spam update"—an algorithm update whose sole purpose is to remove websites that violate anti-spam rules from search results. According to the official Google Search Status Dashboard, the rollout took 2 days and 16 hours and affected all languages and countries simultaneously, including the Czech Republic.

This was the third such update in 2026, following the previous one in June. Google performs these cleanups regularly—usually several times a year—and their purpose differs from that of the classic Core Update, which comprehensively reassesses a website’s quality. A spam update doesn’t address whether your content is useful enough. It addresses whether you’re violating specific, clearly defined rules.

The frequency of these purges is increasing in tandem with how easy it is today to generate large amounts of text using artificial intelligence. Whenever a new tool emerges that makes content creation cheaper, within a few months a group of websites will be found that abuses it to flood search results with junk. Google responds to this with exactly this type of update—not by penalizing AI-generated text across the board, but by specifically removing websites with no real value, which, unfortunately, AI-generated text often is in practice.

A spam update, or something else? You can tell by the shape of the drop

Not every drop in traffic in August is necessarily caused by this particular update. The best way to distinguish a spam update from other algorithm changes is by looking at what the drop looks like on the graph and what specifically was affected.

If you see a sharp drop in rankings exactly between August 18 and 21 or shortly thereafter, and specific subpages have dropped—rather than the entire site dropping evenly—this indicates a spam update. A gradual decline over the course of several weeks usually means something else—most often increasing competition or a technical error. We also see a similar, albeit slower, decline after a poorly executed website migration, when old URLs are removed without being redirected.

How to Find Out If the Downturn Affects You

The quickest way to find the answer is Google Search Console, a free tool directly from Google that shows how your website is performing in search results. If you haven’t set it up yet, this is the first step every business website should complete upon launch.

1. Check the timeline. In the "Performance" section, compare impressions and clicks over the last 30 days. Search for the exact time period August 18–21. Compare the 14 days before and the 14 days after. A sudden drop is the main sign of algorithmic intervention; a gradual decline over several weeks is more likely to indicate a different cause.
2. Compare the date with Google's official calendar. The Google Search Status Dashboard publicly displays the exact dates of each update. If your drop coincides with the rollout period, that’s a strong indication.
3. Check the "Security and Manual Interventions" section. An empty list means you were flagged by an automated algorithm, not a real person at Google. Fixing this is more complicated in this case, because you won't receive a specific explanation of what Google didn't like.
4. If you don't have Search Console, third-party tools can help. Ahrefs, SEMrush, and similar tools display a graph of organic visibility and often plot vertical lines directly on it to indicate the dates of individual updates.

Who Has Google Removed, and Why the Update Usually Doesn't Affect Reputable Companies

The spam update did not target ordinary websites run by small business owners, e-commerce sites, or B2B companies. Instead, it focused on specific types of fraudulent practices that Google has long classified as spam:

• Websites that automatically generate hundreds of articles using AI without any human oversight or editing
• so-called "content farms"—that is, websites that exist solely to generate as many clicks as possible from search results, without providing any real value to readers
• purchased or otherwise fraudulently obtained backlinks—that is, links from other websites intended to artificially boost a site's authority
• expired domains that someone bought solely because of their history and filled with third-party content

If your website honestly describes what you do, is written by you or your team, and you’ve never bought links, the update has most likely helped you. Google has removed some competitors from the results who got there by taking a shortcut, and websites with genuine content have moved up in the rankings. We discuss more about how bought links work and why it pays to avoid them in our article on link building.

In practice, it looks like this: a cabinetmaker who writes a short article once a month about how to choose wood for kitchen cabinets and illustrates it with photos of his own work has no reason to worry. A website full of generic articles about carpentry—articles that were never written or signed by anyone on the editorial staff, and to which a hundred links purchased through a link marketplace lead—is exactly the type of site the update was targeting.

Special Case: E-commerce Sites and Parasitic SEO

E-commerce sites often have a specific vulnerability that the spam update most commonly addresses: so-called parasitic SEO. This refers to a situation where an unauthorized third party, without the owner’s knowledge, creates pages with completely different content—typically related to casinos or pharmaceuticals—on the owner’s domain or subdomain, thereby exploiting the owner’s authority for their own promotion.

If you run an online store, it's worth doing this kind of update Go through the complete list of indexed pages in Search Console and check to see if there are any URLs among them that you never created. The second risk area consists of forgotten subpages from old campaigns or test versions of the website, which unnecessarily waste the crawl budget—that is, the limited capacity Google allocates to them during crawling—on content with no value, rather than on the product pages you want to sell.

What to Do If This Affects You

There’s no quick fix. Google itself has long stated that recovery from such an update takes months rather than days. However, there are a few steps you can take to speed up the recovery process and, more importantly, prevent you from being affected by the next purge.

1. Find out which pages have dropped in rankings. In Search Console, you'll see exactly which specific subpages have dropped the most. Start fixing them first—don't try to fix the entire site at once.
2. Rewrite or delete the blank pages. If a page offers readers nothing of value, it does more harm than good. Either completely revamp it or remove it and set up a redirect. The redirect must lead to a page with similar and more useful content, not just the homepage.
3. Do not copy AI-generated text without reading it first. Artificial intelligence is a useful tool for writing, but you need to review the results yourself and supplement them with real-world experience. If you don't even read the text yourself, sooner or later Google will notice.
4. Write about what you really understand. One well-written article based on personal experience carries more weight with Google than ten average articles generated solely to make the website appear active.
5. Verify that the entire website remains indexable. Sometimes a drop in traffic isn't due to spam, but rather a coincidence with a technical error that occurred during the last update to the website. How to Web indexability We describe how to verify this in a separate article.

Our Approach: How to Write Content So the Next Update Will Only Boost Your Rankings

The August update only confirmed the direction Google has been taking for some time. It rewards websites run by real people with genuine experience and is becoming increasingly intolerant of content created solely to fill space in search results. We described this trend in detail in an article about, How to Stay Visible in the Age of AI Search.

Artificial intelligence, however, is not a problem in and of itself. The problem is content that is created without oversight and without adding value. We discuss the difference between when blogging still makes sense and when it’s just a waste of time in an article about blogging in the age of AI. Consistency and authenticity usually last longer than any algorithmic trick. If you want to be successful in the long run, publish content that no one else can write—such as case studies from your company, specific experiences, and so on. If you include your own data in an article, you’re halfway there.

Frequently Asked Questions

How can I tell if I've been affected by the Google Spam Update?

Open Google Search Console and, in the "Performance" section, compare traffic from around August 18 to 21, 2026, with the same period one month earlier. A sudden drop in impressions and clicks during this exact time frame is the main sign that you’ve been affected by this update.

How does a Spam Update differ from a Core Update?

A spam update targets specific fraudulent practices, such as purchased links or automatically generated content, and the drop in rankings tends to be sharp and affects specific pages. A core update, on the other hand, reassesses a website’s overall quality and relevance to the search intent, and its impact is usually more gradual.

Can AI-generated blog posts harm me?

Using AI to write isn't a problem in and of itself. The problem arises when the text is published without human review, editing, and the input of human experience. Google penalizes content that lacks value, not the specific tool used to create it.

How long does it take to recover after an update?

Google has long stated that recovery from a spam update is a matter of months rather than days or weeks. The fastest way to return to your original rankings is to quickly revise or remove the problematic pages and stop generating unchecked content.

Which metrics in Search Console should I monitor after the update?

The most revealing metrics are page views and clicks over time, broken down by individual pages, not just an aggregate number for the entire website. If your average ranking for key search terms has also dropped, this is a stronger signal than just a decline in traffic, which may be due to seasonal factors. We describe which metrics are worth tracking over the long term in our article on the topic, What metrics should you track on your website?.

Summary

The August anti-spam update targeted websites with purchased links, content farms, and unmoderated AI-generated text. A legitimate business website written by a real person usually has nothing to fear, and for many of them, the update actually helped by weeding out the competition. If you’ve still been affected by the drop in rankings, the key is to find the specific affected pages in Search Console and fix them—don’t wait for the situation to resolve itself.
