Google Algorithm Updates: Timeline & Recovery

Google's algorithm changes can make or break your organic traffic overnight. This continuously updated guide tracks confirmed Google updates, analyzes their impact, and provides actionable recovery strategies for sites affected by ranking changes.

This page is a maintained hub: we review and update it quarterly as Google confirms new algorithm changes.

Google Algorithm Update Timeline

Every entry below is a ranking update listed on Google's Search Status Dashboard, with the start date and rollout duration the dashboard shows (checked 31 October 2026). Google does not publish a detailed changelog for core or spam updates, so this page lists only what Google has confirmed.

2026

Update	Started	Rollout duration
September 2026 spam update	2026-09-24	13 days, 16 hours
August 2026 spam update	2026-08-18	2 days, 16 hours
June 2026 spam update	2026-06-24	2 days, 1 hour
May 2026 core update	2026-05-21	11 days, 21 hours
March 2026 core update	2026-03-27	12 days, 4 hours
March 2026 spam update	2026-03-24	19 hours, 30 minutes
February 2026 Discover update	2026-02-05	21 days, 17 hours

2025

Update	Started	Rollout duration
December 2025 core update	2025-12-11	18 days, 2 hours
August 2025 spam update	2025-08-26	26 days, 15 hours
June 2025 core update	2025-06-30	16 days, 18 hours
March 2025 core update	2025-03-13	13 days, 21 hours

Earlier versions of this page listed a May 2025 "Page Experience Update", a May 2025 "Reviews Update", an April 2025 spam update, a February 2025 helpful content update and a January 2025 link spam update, and dated the March 2025 core update to 12 March. Google's dashboard lists none of those five updates and starts the March 2025 core update on 13 March, so the entries have been removed or corrected. There is also no longer a separate helpful content update: in March 2024 the helpful content system "evolved and became part of our core ranking systems" (Google's ranking systems guide).

Understanding Google Update Patterns

Core Updates vs. Spam Updates

Core updates are broad changes to ranking. Google says it makes them "several times a year" (Google Search Central). The dashboard lists four in 2024, three in 2025 and two so far in 2026. Since 2025 they have taken between 11 days, 21 hours and 18 days, 2 hours to roll out.

Spam updates target Google's spam policies. Their rollouts vary much more: from 19 hours, 30 minutes (March 2026) to 26 days, 15 hours (August 2025).

What the Record Shows

1. Spam updates became more frequent: one in 2025, four in the first nine months of 2026.
2. Core updates now finish in roughly two weeks; the March 2024 core update took 45 days.
3. In February 2026 Google listed an update for Discover rather than for Search results.

Algorithm-Specific Recovery Strategies

Google gives no fixed recovery timeline.

Earlier versions of this page gave a recovery time and a success rate for each update type; they had no source and have been removed.

FAQ: Common Update Questions

Q: How long do updates take to fully roll out? A: It varies. On the Search Status Dashboard, core updates since 2025 took between 11 days, 21 hours and 18 days, 2 hours, and spam updates between 19 hours, 30 minutes and 26 days, 15 hours.

Q: Can I recover from an algorithm hit? A: Often, but Google makes no promise: it says there is "no guarantee" that changes will have a noticeable impact, and recovery can mean waiting until the next core update (Google Search Central).

Q: Should I make changes during an update? A: No, wait until the update completes to accurately assess impact.

Q: How do I know if I was hit by an update? A: Check Google Search Console for sudden traffic changes coinciding with update dates.

Q: Do all updates affect all sites? A: No, updates often target specific quality issues or site types.

When reviewing a site after a core update, Google's E-E-A-T framework is a useful lens for judging how helpful and trustworthy its content is.
