Google Algorithm Updates: Latest News and Full History

This page exists because Google names some of its ranking updates. It is useful to know what Google thinks that naming is for.

On 27th Aug, SEO consultant Shahram Rahbari asked John Mueller on Bluesky whether naming an update publicly is "meant to give site owners any actionable signal at the page or site level, or is it purely a timing/transparency notice with no specific action expected from webmasters?"

Mueller answered the same evening: "This is primarily transparency for site owners. If there's something actionable for site owners to do, we'll publish that in our policies, help center, documentation, and blog independently -- usually well in advance of any changes in our systems."

Two things follow for anyone reading a dashboard row. A named update is a timing notice.

It tells you when to look at your analytics, and nothing about what to change.

And the instruction, when there is one, comes through a different channel and lands first. The site reputation policy change for the EEA the day after Mueller's post is the shape.

It arrived as a blog post, a documentation change and advance notice, all separate from any dashboard entry.

That ordering is the practical part. If you wait for a named update to tell you what to do, you are late.

The guidance has already been published somewhere else, usually weeks earlier.

One claim in the coverage is not Google's. Search Engine Roundtable's write-up adds that "Google does not announce all updates, not even smaller core updates".

Mueller's post does not say that. Google's own core-update documentation says the reverse for core updates: "Several times a year, Google makes significant, broad changes to our search algorithms and systems. We refer to these as core updates, and we give notice when they happen on our list of Google Search ranking updates."

The wider point underneath it is not in dispute. Google has always said it makes many ranking changes it never names.

That is why unexplained ranking swings with no dashboard row stay unpublished on this page.

Hover a result in Google Search and the status bar may now show a google.com/goto address. It is no longer the address of the page you are about to visit.

A server-side redirect now sits between the results page and the destination. Search Engine Roundtable reported on 26th Aug that Google has confirmed the change is rolling out.

A Google spokesperson gave that site a short statement. It does not name what Google is defending against: "We have a long history of deploying technical measures against evolving forms of abuse, and we regularly take steps to protect our services and users."

Search Engine Land, carrying the same confirmation, describes the link shape. The click goes to google.com/goto?url= plus a hashed form of the destination URL.

The redirect then delivers the page.

The measurement side is where this lands for anyone doing SEO. That evidence comes from a provider rather than from Google.

Derek Perkins of the rank-tracking firm Nozzle posted on 26th Aug. Google has been testing "anti-bot measures that eliminate all client side links" in favour of the goto redirects.

The first major test was widely reported in the first week of August. By that morning he was seeing "near 100% rollout across several residential ip providers".

His chart covers roughly four months of the test. Nozzle has been discarding the affected results pages "so that our customer data isn't polluted with opaque links".

The practical problem he describes is one of cost rather than possibility. "The goto links can't be decoded, so providers will have to follow the redirect links", which works at small scale, and "each SERP will have hundreds of links to decode".

He compares it to the num=100 change of autumn 2025. That is the closest precedent for a Google change that broke third-party rank data without touching rankings.

Two things are not established, and both matter before anyone acts on this.

Google's confirmation names abuse and nothing else. The widely repeated reading that this targets AI companies scraping results is other people's inference, not Google's stated reason.

Search Engine Land draws that inference in its own voice. It writes that the change "should make it harder for third-party tools, services, scrapers, and AI engines to scrape the Google search results".

It also points at SerpAPI, a scraping firm it notes Google sued and recently lost a motion against. That is the outlet's technical reading, and Google has not said it.

We have also seen no evidence on whether links inside AI Overviews and AI Mode are affected. The same goes for whether anything changes in the referrer a site receives.

Neither the statement nor the rollout reports address either question.

Search Console is the same kind of open question. Search Engine Land writes that "you have to assume" its data is unaffected, and an assumption is all that is.

Google marked the August 2026 spam update complete on the Search Status Dashboard on 21st Aug 2026. The time was 08:49 UTC, about 4:50 am US Eastern.

Measured from its 16:27 UTC start on 18th Aug, the rollout ran 2 days, 16 hours and 22 minutes. Google's own wording on the incident is simply "The rollout was complete as of August 21, 2026."

That is the longest of the three spam updates Google has shipped in 2026. It beat the June update's 2 days 1 hour by roughly 15 hours.

The March update's 19 hours 30 minutes is still the fastest rollout the dashboard has ever recorded.

It is nowhere near the longest on record. The August 2025 spam update took 26 days 15 hours.

So the 2026 pattern still holds: spam updates now land inside a few days rather than a few weeks.

What "complete" does and does not mean is the part to get right before you read your analytics.

It means the rollout Google announced has finished deploying. Ranking movement caused by this update should have settled.

It does not mean the systems behind it have stopped. Google told Search Engine Roundtable that it will run periodic refreshes of the spam update.

Those refreshes can move rankings again without any new announcement.

Google also repeated its standing position that recovery from a spam demotion can take many months. There is no reconsideration request for an algorithmic demotion.

If you lost rankings between 18th and 21st Aug, the useful next step is narrower than a general content audit. Google ruled out two suspects when it released this one.

It does not target link spam, and it has nothing to do with the site reputation abuse policy.

That points at the rest of the spam policies. Hacked or scraped content, doorway pages, expired-domain abuse and scaled content abuse are the categories that catch otherwise legitimate sites.

Our page on this update carries the full rollout timeline.

Google released the August 2026 spam update on 18th Aug 2026 at 16:27 UTC. It was Google's first confirmed ranking update since the June spam update completed on 26th Jun.

The Search Status Dashboard entry reads: "Released the August 2026 spam update, which applies globally and to all languages. The rollout may take a few days to complete."

Google's own announcement calls it "a normal spam update". It finished rolling out on 21st Aug at 08:49 UTC, after 2 days 16 hours.

That makes it the longest of the three spam updates Google has run in 2026.

Many people reported ranking swings in the days before the announcement. John Mueller settled the question on LinkedIn: "We don't roll them out beforehand. We try to get the announcement as close as possible to the actual "button-pushing" (which is sometimes challenging due to time-zones)."

Search Engine Roundtable collected the reply and adds the qualification that matters. Google does run smaller core updates without announcing them.

So movement before 18th Aug was real, it just was not this update.

Google told Search Engine Roundtable that the update targets sites violating some of its search spam policies. It also confirmed two things the update does not do.

It does not target link spam, and it is unrelated to the site reputation abuse policy.

Google declined to say what share of queries or searches the update affects. It also said it will run periodic refreshes of the spam update.

Google repeated its standing guidance that recovery from a spam demotion can take many months.

This is the third spam update Google has announced in 2026.

If your rankings moved from 18th Aug onwards, treat it as a spam-policy question rather than a content-quality one. Work through Google's spam policies first.

Look for hacked or scraped content, doorway pages, expired-domain abuse and scaled content abuse before assuming a core-update-style problem. Our full page on this update carries the day-by-day rollout timeline and the completion date.

Google released the June 2026 spam update on 24th Jun and marked it complete on 26th Jun. The 2-day, 1-hour rollout continues the much faster spam deployments Google has shipped since March.

Google described it as "a normal spam update" applying globally and to all languages. It confirmed the update does not specifically target link spam or the site reputation abuse policy.

Sites that were demoted should expect recovery, if earned, to take months rather than days.

The May 2026 core update began on 21st May and completed on 2nd Jun after 11 days and 21 hours. Search Engine Roundtable called it "a big one, causing a lot of search ranking volatility".

Tracker spikes came around 23rd May, 30th May and the final 24 hours of the rollout.

It was a standard broad core update, the second of 2026. Google pointed to its usual guidance on core updates rather than any specific target.

The March 2026 core update began on 27th Mar, three days after the March spam update completed. It finished on 8th Apr, after 12 days and 4 hours.

During the rollout, Google's John Mueller addressed why ranking swings come in waves: "We generally don't announce 'stages' of core updates... sometimes they have to work step-by-step, rather than all at one time". He added that there is no single "core update machine" being switched on.

Google's March 2026 spam update completed in 19 hours and 30 minutes. That is the fastest rollout of any update documented on the Search Status Dashboard since it launched.

For comparison, the August 2025 spam update took over 26 days.

The speed was widely read as evidence that Google's spam systems can now deploy globally in a single push. In 2024 and 2025, spam rollouts took weeks.

Google completed the February 2026 Discover core update on 27th Feb after roughly three weeks.

It is the first core update scoped to Discover rather than Search. Per Google, it was "released... for English language users in the US (will look to expand it to all countries and languages in the future)" and "is designed to improve the quality of Discover overall."

As of early July 2026 Google has not announced an expansion beyond US English.

The December 2025 core update rolled out from 11th Dec to 29th Dec, 18 days and 2 hours. It closed a year with three core updates (March, June, December) and one spam update (August).

Google flagged at release that the rollout "may take up to 3 weeks", and it nearly did.
