Google released the September 2026 spam update this morning, and the phrase that stands out on the Search Status Dashboard is the last one: “The rollout may take up to two weeks to complete.”
This year’s three earlier spam updates were quick. By the dashboard’s own records, March’s took 19 hours and 30 minutes, June’s 2 days and 1 hour, and August’s 2 days and 16 hours. Search Engine Journal notes that Google gave each of those a window of “a few days.” John Mueller confirmed to Search Engine Roundtable that two weeks was not a typo: “Yes, it’s likely to take longer than some of the previous ones.” Beyond calling it “a normal spam update,” Google has not said what it targets.
The dashboard’s history is a useful case file for what a longer window means.
What longer spam rollouts have looked like
Long spam updates are not new. They were simply absent this year. The October 2023 spam update ran about 15 and a half days. March 2024’s ran almost 15, alongside a core update that took 45. The August 2025 spam update ran 26 days and 15 hours.
SEJ makes the right caveat: an estimate of up to two weeks does not mean it will take the full two weeks. What the history does show is that the length of a rollout tells you how long the ground may keep moving, not when any particular page will feel it. Effects can arrive early, late or in more than one wave. Any single day’s snapshot during the window is a partial reading.
Why this matters beyond SEO teams
Spam updates are usually discussed as a site-owner problem. Did my traffic drop? For reputation monitoring the more relevant question is what happens to the pages around you. Spam systems act on manipulative and low-value pages, and in name and brand searches those are often third-party pages: scraped profiles, thin “review” sites, auto-generated comparisons, pages built to capture an executive’s name. When they move, everything else on the page moves with them, including the pages a company wants seen and the critical coverage it would rather were not.
The same pages can feed answer engines that retrieve from the open web. When a spammy page drops out of results, it may stop being cited, or it may linger in systems that refresh on their own schedule. Two weeks of change underneath the results can mean two weeks of shifting summaries on top of them.
A routine for the next two weeks
First, record what you see today for priority name and brand queries, including any AI Overview, and date it. That is the only pre-update baseline you will get.
Second, keep a log of everything else that happens during the window: news coverage, executive moves, Wikipedia edits, pages you publish. A shift that coincides with a news cycle should not be blamed on a spam update, and the reverse is also true.
Third, hold conclusions until Google marks the rollout complete. A low-quality page that disappears on day three can return. A critical article that slips may recover. Reporting either one to leadership as settled on day two means delivering the wrong answer with confidence.
Fourth, after completion, compare against the baseline and ask a specific question: which third-party pages left or entered the first page, and did the sources that answer engines cite change with them?
In 2024 I wrote that cited answers could become the new homepage. When the homepage is assembled from sources, the quality of the sources around you becomes part of your reputation. A spam update is one of the few occasions when Google announces in advance that those sources are about to be reshuffled. This time it also told everyone to be patient.
