The timestamp matters more than the speculation. Google has confirmed a new spam update, but it has not said which sites or tactics this release will affect.
The Google Search Status Dashboard records the start of the September 2026 spam update at 9:15 a.m. Pacific time on September 24. Google says the change applies globally, covers all languages and may take up to two weeks to finish rolling out. At the time of this draft, the dashboard lists the rollout as in progress.
What Google has—and has not—said
Google’s general spam update guidance says its automated systems continually detect search spam and that named updates are notable improvements to those systems. It advises sites affected by an update to review the company’s spam policies. It does not say this September release is specifically about AI-written content, links, expired domains or any other single tactic. Claims that it targets one of those practices would go beyond the announcement.
The distinction matters for publishers. A change in clicks on the same day as the rollout is a signal to investigate, not a diagnosis. Search traffic also moves because of demand, competing pages, technical faults and ordinary reporting variation. Google’s own estimate allows the rollout to continue for as long as two weeks, so the first few hours are an especially weak basis for sweeping conclusions.
A measured way to watch the rollout
Record the start date, then compare Search Console performance by page group, query and country against a comparable pre-update period. Keep brand queries separate from non-brand queries. Check whether any apparent loss is concentrated on a small set of URLs or occurs across an entire section. Before rewriting or deleting content, rule out indexing changes, server errors, accidental noindex tags and a recent redesign.
The new multimodal Search Console filter is also rolling out on September 24. Keep that reporting change separate from the spam update when you compare traffic: a newly visible slice of searches is not proof of a ranking gain or loss.
If a site does appear affected after the rollout, review the relevant Google spam policies against actual pages and practices. Google’s guidance says improvements may take months for its automated systems to recognize; it does not promise that a quick edit will restore previous positions.
For MustHave.ai and other large directories, the practical lesson is to assess thin, duplicative or outdated pages against the policies and the value they offer readers. That is a quality audit to perform on its own merits, not a claim that this update specifically targets directories. Until Google publishes more detail, the dashboard is the reliable source for the rollout’s timing and completion.
Our earlier guide to what Google still punishes in AI-assisted SEO covers the lasting policy issues. The September update does not change the need to judge each page by its usefulness rather than by whether AI helped draft it.
