Google announced it on the Search Status Dashboard only, with no blog post or impact figures. It began two days after the March 2026 spam update completed. ## Key takeaways - The Search Status Dashboard dates the rollout from 27 March 2026 to 8 April 2026, a 12-day run. - Google said at launch that the rollout may take up to two weeks, and it finished inside that window. - Google published no Search Central blog post and no impact figures for this update. - The March 2026 spam update finished on 25 March, two days before this rollout began. - Google's core update guidance applies: wait a week after completion, then compare like-for-like weeks. ## What Google changed Google's only announcement was the Search Status Dashboard entry: "Released the March 2026 core update." It published no Search Central blog post and named no specific system or change. Its standing documentation describes core updates as "significant, broad changes to our search algorithms and systems" that "don't target specific sites or individual web pages." ## When it rolled out The [Google Search Status Dashboard](https://status.search.google.com/incidents/7eTbAa2jWdToLkraZj5y) logged the release on 27 March 2026 at 02:14 PDT with the note that "the rollout may take up to 2 weeks to complete." Google posted on 8 April 2026 at 06:12 PDT that "the rollout was complete as of April 8, 2026," a total of 12 days. The March 2026 spam update ran just before it, from 24 March to 25 March 2026. The two rollouts did not overlap, but they are two days apart, so a weekly chart can blend them. Check daily data around 24 to 27 March before attributing a change to either one. ## What is known about its impact Google did not publish any impact figures for this update. Its documentation says most sites "don't need to worry about core updates and may not even realize one has happened," and that pages which move down "aren't necessarily bad"; other pages may simply serve the searcher better. 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 standing core update guidance sets out the steps: - Wait until the rollout has finished, then at least one more full week. - Compare the week after with a week before the update began, not with the rollout window. - A small drop (position 2 to 4) needs no drastic action; a large, sustained drop warrants a site-wide self-assessment against Google's helpful, reliable, people-first content questions. - Avoid quick fixes. Improve content in ways that help readers; delete content only as a last resort. - Recovery can take months, though Google says smaller, unannounced core updates can also reflect improvements before the next major one. ## How to check whether it affected you In Search Console, set the Performance report to a range spanning March to April 2026 and compare clicks for the week before 24 March, which predates both March updates, with the week starting 15 April. Look at Web, Image, Video and News search types separately, as Google recommends. The [Google Algorithm Updates timeline](/updates) lists every confirmed update with its dates, so you can separate this rollout from the spam update that preceded it. ## Related updates - The [December 2025 core update](/updates/december-2025-core-update) was the core update before it. - The [May 2026 core update](/updates/may-2026-core-update) was the next one. - The [March 2026 spam update](/updates/march-2026-spam-update) finished two days before it began. ## Frequently asked questions ### When did the March 2026 core update start and finish?
