Google confirms roughly 8 to 12 named updates a year and makes thousands more it never announces.
This is a maintained record of the ones that matter, what each targeted, and how to tell whether one affected your site.
How Often Google Updates Search
Google has confirmed 25 named updates since the start of 2023, when it began publishing rollouts on its Search Status Dashboard. Broad core updates now arrive roughly every 3 months, up from about twice a year historically.
Rollout length varies enormously. The March 2026 spam update completed in about 19.5 hours, the fastest on record. The March 2024 core update took 45 days, the longest. Most core updates land somewhere between 12 and 20 days, and rankings can move in both directions repeatedly during the window before settling.
Every Confirmed Update in 2026
Five confirmed updates so far this year: 2 core, 2 spam, and 1 specific to Discover.
June 2026 spam update
Ran June 24 to 26, completing in about 2 days. Google described it as a normal spam update applying globally and to all languages, and confirmed it did not specifically target link spam or the site reputation abuse policy.
Sites demoted by a spam update should expect recovery, if earned, to take months rather than days.
May 2026 core update
Ran May 21 to June 2, taking 11 days and 21 hours.
Trackers reported heavy volatility around May 23, May 30 and the final 24 hours, which is a normal pattern rather than 3 separate events.
March 2026 core update
Ran March 27 to April 8. Third party analysis suggests it moved rankings on a majority of tracked sites and that pages relying on templated AI content for long tail queries lost the most ground, while pages with named authors, original research and first-hand experience gained.
Some analysts also reported that Core Web Vitals began being scored as a combined performance signal rather than 3 separate metrics. Google has not confirmed either characterisation.
March 2026 spam update
Ran March 24 to 25, completing in roughly 19.5 hours.
The fastest confirmed rollout on record.
February 2026 Discover core update
Specific to Google Discover rather than web search. Relevant mainly to publishers who get significant traffic from the Discover feed.
The Updates That Still Shape Rankings
Most of the famous named algorithms no longer run as separate updates. They were absorbed into the core algorithm, which is why you rarely hear their names now and why chasing them individually is a waste of time.
Panda, 2011
Targeted thin and low quality content. Folded into the core algorithm in 2016. Its logic is still the reason a page of 300 generic words does not rank.
Penguin, 2012
Targeted manipulative link building. Became part of the core algorithm and real time in 2016, which means link-based demotions now happen continuously rather than at update time.
Hummingbird, 2013
Shifted Google from matching keywords to understanding meaning. The reason writing naturally now beats repeating an exact phrase.
Mobile-friendly, 2015
Made mobile usability a ranking factor. Now simply assumed. Google indexes the mobile version of your site by default.
RankBrain, 2015
Google’s first machine learning ranking component, used to interpret queries it has never seen before.
BERT, 2019
Natural language understanding applied to the relationships between words in a query, particularly prepositions that change meaning entirely.
Page Experience and Core Web Vitals, 2021
Introduced loading, interactivity and visual stability as measurable ranking signals. Google has since replaced First Input Delay with Interaction to Next Paint. If you want to check where your site stands, our list of website speed test tools covers how.
Helpful Content, 2022
Targeted content written for search engines rather than people. Ran as a separate system until March 2024, when Google folded it into the core algorithm. This matters: there is no longer a standalone helpful content update to recover from, because the signal is now part of every core update.
Site reputation abuse policy, 2024
Aimed at third party content published on an established domain to borrow its authority, sometimes called parasite SEO. Enforced as a spam policy rather than an algorithm, which means it can be applied manually.
What Google Targets in Spam Updates
Core updates re evaluate quality broadly. Spam updates are narrower and enforce specific policies, usually through SpamBrain, Google’s AI-based spam detection system.
The recurring targets are scaled content abuse, meaning mass-produced pages with little value regardless of whether a human or a machine wrote them, expired domain abuse, where an aged domain is bought for its backlinks and repurposed, link schemes, and site reputation abuse.
The practical difference matters for recovery. A core update demotion usually means your content was judged less useful than a competitor’s, and improvement can show at the next core update.
A spam demotion means a policy was broken, and recovery typically takes months even after the problem is fixed.
How to Tell if an Update Hit You
Traffic drops for many reasons and most of them are not algorithm updates. Work through this before assuming.
- Check the date against the Search Status Dashboard. If your drop started on a day when nothing was rolling out, it was not an update.
- Check whether the drop is site wide or page specific. Core updates usually move a whole site or a whole content type. A single page dropping is more often a technical issue or a competitor improving.
- Check impressions, not just clicks, in Search Console. Falling impressions means ranking loss. Stable impressions with falling clicks means something changed in the results page around you, such as an AI Overview appearing above you.
- Check whether it is seasonal. Compare to the same period last year before panicking.
- Wait for the rollout to finish. Rankings fluctuate during a rollout, and acting in the middle of one means responding to a number that is not final.
If the answer is that no update was running, the cause is somewhere else. Our guide to why a website is not ranking on Google covers the more common explanations.
What to Do During a Rollout
Very little, which is the hardest advice to follow.
Rankings move up and down repeatedly during a rollout, so a drop on day 3 tells you nothing about where you will land on day 15. Making changes mid-rollout means you cannot tell afterwards whether the recovery was the update settling or the change you made.
Record what happened instead. Note the start date, take a Search Console export of your top pages before and after, and wait for Google to mark the rollout complete. Then compare. That is the only version of this that produces usable information.
Recovering After a Core Update
Google’s own guidance on core updates has been consistent for years: there is nothing to fix in the sense of a penalty. A core update is a reassessment of which pages best serve a query, so a drop means other pages were judged more useful, not that you did something wrong.
Which means the recovery path is not a checklist. It is improving the pages themselves, and the improvement usually only becomes visible at the next core update rather than immediately. That is 3 months of patience on the current cadence.
What consistently gains ground across recent updates: content with a named author who has real experience of the subject, original information rather than a rearrangement of what already ranks, and pages that answer the question they were written for without padding. What consistently loses: templated content produced at scale for long-tail queries with no expertise behind it.
Updates You Can Safely Ignore
Trackers report ranking volatility constantly, and most of it is not a confirmed update. In August 2026, third party tools showed a spike on the 12th and 13th while Google confirmed no update had run since June.
Unconfirmed volatility is worth noting and not worth acting on. Google makes thousands of unannounced changes a year and normal fluctuation looks identical to a small update in a tracking tool. If it is not on the Search Status Dashboard and your own Search Console data does not show a sustained change over 2 weeks, treat it as noise.

Frequently Asked Questions
Google confirms roughly 8 to 12 named updates per year, including core updates, spam updates and occasional feature specific updates. On top of that it makes thousands of unannounced adjustments annually. Only the confirmed ones appear on the Search Status Dashboard, and only those are worth diagnosing against.
The most recent confirmed core update is the May 2026 core update, which ran from May 21 to June 2 and took 11 days and 21 hours. It followed the March 2026 core update, which ran from March 27 to April 8. Core updates currently arrive about every 3 months.
Usually 12 to 20 days, though the range is wide. The March 2024 core update took 45 days, the longest on record, while the March 2026 spam update finished in about 19.5 hours. Rankings fluctuate throughout, so wait for Google to mark the rollout complete before drawing conclusions.
For a core update, there is no penalty to lift. Google’s guidance is to improve the content itself, and improvements typically only surface at the next core update, roughly 3 months later. For a spam update, identify which policy was breached, fix it, and expect recovery to take months rather than days.
Not as a separate system. Google folded the helpful content signal into its core algorithm in March 2024, so there is no longer a standalone helpful content update to be hit by or recover from. The same judgement now happens inside every core update.
No. Google confirms the significant ones on its Search Status Dashboard and makes thousands of smaller changes without announcement. If a tracking tool shows volatility and Google has confirmed nothing, it is usually normal fluctuation rather than something to respond to.
The Practical Takeaway
You cannot optimise for a specific algorithm, and every attempt to do so ages badly. Panda, Penguin and Helpful Content all became part of the core, which means the tactics built around gaming them stopped working while the underlying principle stayed the same.
What survives every update is the same thing it has been since Panda in 2011: pages that genuinely answer what someone searched for, written by someone who knows the subject, on a site that loads and works. Everything else is a tactic with an expiry date.
