It applied globally and to all languages. Google published no blog post or impact figures, and the March 2026 core update began two days later. ## Key takeaways - The Search Status Dashboard dates the rollout from 24 March 2026 to 25 March 2026, about one day. - Google said the update applies globally and to all languages and may take a few days to complete. - Google published no Search Central blog post and no impact figures for this update. - The March 2026 core update started on 27 March, two days after this rollout completed. - Sites hit by a spam update should review Google's spam policies, as recovery can take months. ## What Google changed Google's only announcement was the Search Status Dashboard entry: "Released the March 2026 spam update, which applies globally and to all languages." It published no Search Central blog post and did not say which type of spam the update addressed. Google's spam updates page explains the general mechanism. Its automated spam detection runs constantly, and a spam update is a notable improvement to how those systems work. It names SpamBrain, its AI-based spam-prevention system, as one system it improves "to help ensure it catches new types of spam." ## When it rolled out The [Google Search Status Dashboard](https://status.search.google.com/incidents/VbnSXAH4SmEcxPtx4YSD) logged the release on 24 March 2026 at 12:18 PDT with the note that "the rollout may take a few days to complete." Google posted on 25 March 2026 at 07:39 PDT that "the rollout was complete as of March 25, 2026," about one day after release. The March 2026 core update started two days later, on 27 March 2026. The rollouts did not overlap, but they sit close enough that a weekly chart blends them. Read daily data before deciding which one moved your traffic. ## What is known about its impact Google did not publish any impact figures for this update. Its spam policies state that "sites that violate our policies may rank lower in results or not appear in results at all," but Google gave no count of affected sites or queries. Treat any percentage you see attributed to this update as a third-party estimate, and check its method. ## What site owners should do Google's guidance for spam updates is short: - Review your site against Google's spam policies, which cover practices such as cloaking, link spam, scaled content abuse, scraping and expired domain abuse. - Remove or fix anything that breaks them. Google detects violations through automated systems and, where needed, human review that can lead to a manual action. - Check the Manual actions report in Search Console, since a manual action is separate from an automated spam update. - Expect a slow recovery. Google says changes may help once its systems learn, over a period of months, that the site complies. ## How to check whether it affected you In Search Console, open the Performance report with a daily view spanning mid March to early April 2026. A spam update effect should begin between 24 and 25 March; a change that starts on or after 27 March is more likely tied to the core update. Compare daily clicks for the week before 24 March with 25 and 26 March, before the core update began. The [Google Algorithm Updates timeline](/updates) lists every confirmed update with its dates. ## Related updates - The [August 2025 spam update](/updates/august-2025-spam-update) was the spam update before it. - The [June 2026 spam update](/updates/june-2026-spam-update) was the next one. - The [March 2026 core update](/updates/march-2026-core-update) began two days after it finished. ## Frequently asked questions ### When did the March 2026 spam update start and finish?
