No Core Update in September. But There Was a Change That Does Affect You.
Google confirmed a spam update in August 2026 and changed its site reputation abuse enforcement in Europe. What each one means for an SME.
In August 2026 two different things actually happened, and it is worth not mixing them up. The August 2026 spam update rolled out on 18 August and completed in two days and sixteen hours, aimed at “scaled content abuse” (mass-produced, low-value content). Separately, days later, Google changed how it enforces its “site reputation abuse” policy in Europe only — a regulatory decision, not an algorithm update.
What exactly is the August 2026 spam update?
It is a SpamBrain update aimed specifically at scaled content abuse — pages produced en masse with little real value for the reader — together with deceptive freshness and hidden text. Google explicitly confirmed that this update was not aimed at link spam or at site reputation abuse.
The rollout began on 18 August 2026 and completed at 4:51 am (US Eastern Time) on 21 August — two days and sixteen hours, one of the fastest rollouts of the year, a long way from the 27 days the August 2025 spam update took.
What “site reputation abuse” is and why it is now enforced differently in Europe
Site reputation abuse (also called “parasite SEO”) is publishing third-party content on an established site to take advantage of its ranking authority. On 27 August 2026, Google announced it was no longer applying manual actions for this practice in the European Economic Area, with effect from 30 August.
The change came after publishers complained to the European Commission that the policy penalised news media for including content from commercial partners, and after an investigation was opened under the Digital Markets Act that could lead to a fine of up to 10% of Google’s global turnover. Outside the EEA, the policy remains exactly the same.
How to tell whether a traffic movement is this update or just normal noise
SE Ranking’s analysis of 100,000 keywords across 20 sectors shows that, during the update, 16.71% of URLs that were in the top 10 fell beyond position 100 — compared with 9.2% in a quiet reference period. That is an 82% increase.
If your page dropped from the top 10 to, say, position 25, that is normal movement for any update. If it suddenly dropped beyond position 100, that is a different category of event and far more likely to be directly linked to this spam update rather than routine fluctuation.
Which practices are definitively off the table after this change
Since 15 May 2026, the definition of scaled content abuse has been broadened to also cover manipulation of AI answers: fabricating content designed solely to influence what a generative model says is now considered spam, not just manipulating classic rankings.
That includes pages generated in volume with little added value, changing publication dates with no real change to the content (“deceptive freshness”), and hidden text intended only for crawlers. The question to ask before publishing is no longer just “does this help the ranking?” but “does this also help an AI model cite me accurately?”.
Why not every ranking movement is a new algorithm
Volatility in this update varied widely by sector: from 74.64% in real estate to 85.55% in fashion and beauty, with YMYL categories such as health and real estate among the most stable. Not every traffic drop in September has anything to do with this particular update.
Before assuming a new algorithm has penalised you, it is worth ruling out the obvious: recent technical changes to the site, seasonality in your sector, or a loss of backlinks that has nothing to do with SpamBrain. Attributing every drop to “the latest Google update” without checking leads to fixing the wrong problem.
What to do (and what not to do) if you notice drops right now
- Check the real size of the drop. Top 10 to top 100 is not the same as top 10 to outside the top 100.
- Check whether there is content produced in volume with little added value in the part of the site that has dropped.
- Don’t react in the heat of the moment by rewriting everything. Google indicates that recovery from these updates can take a period of several months, not days.
- Don’t confuse this update with site reputation abuse. Google explicitly confirmed that this August update was not targeting that practice.
Table: the two things that happened in August 2026, kept separate
| Spam update (18–21 Aug) | Site reputation abuse change (27–30 Aug) | |
|---|---|---|
| What it is | Algorithm update (SpamBrain) | Enforcement change under regulatory pressure |
| Who it affects | Everyone, globally | Only sites operating in the EEA |
| Target | Scaled content abuse, deceptive freshness | “Parasite SEO” — not the target of the spam update |
| Rollout duration | 2 days, 16 hours | Not applicable (policy change, not an algorithmic rollout) |
How we work on this at Impactiq
We review every spam update by separating noise from real signal, and we check whether our clients’ content follows the practices Google has considered spam since May 2026 — including manipulation of AI answers. You can see how we apply this discipline in our coverage of the December 2025 Core Update or on our SEO services page.
If you have noticed a traffic drop in recent weeks and don’t know whether it is this update or something else, we’ll review it with you in 30 minutes, without assuming it is “the algorithm” before checking.
There was no core update in September. But there was something that does affect you.
We check whether your traffic drop is related to the August update or is something else, before you rewrite content that didn’t need it.

Frequently asked questions
What is Google’s August 2026 spam update?
A SpamBrain update against scaled content abuse, deceptive freshness and hidden text. It rolled out on 18 August and completed in two days and sixteen hours.
Is it the same as the “site reputation abuse” change in Europe?
No. Google confirmed that the August update was not targeting site reputation abuse. The change to that policy, for the EEA only, was a separate regulatory announcement, on 27–30 August.
Why did Google change its site reputation abuse policy in Europe?
Under pressure from the European Commission following complaints from publishers, and to avoid a possible fine under the Digital Markets Act of up to 10% of its global turnover.
How do I know whether my traffic drop is due to this update?
If your URL dropped from the top 10 to beyond position 100 during 17–22 August, it is more likely to be linked to the update. Moderate drops are usually normal fluctuation.
Is manipulating AI answers already considered spam?
Yes, since 15 May 2026 Google has broadened the definition of scaled content abuse to also cover content fabricated to influence generative AI answers.
