Google algorithm updates in 2026: what changed and what your content needs now

Between November 2025 and October 2026, Google confirmed eight Google algorithm updates on its Search Status Dashboard: three core updates, four spam updates and one update aimed only at Discover. It also quietly changed several of its spam policies and guidance documents. This guide sets out the confirmed timeline for 2026 so far, explains what Google actually said about each update, and turns Google's own documentation into practical guidance for anyone publishing content.

We've only included updates Google confirmed. Ranking tools and SEO forums report plenty of unconfirmed "volatility" in any given month, but without confirmation from Google it's guesswork, so it's left out. Dates are as Google lists them on the dashboard, in US Pacific time.

Every confirmed Google algorithm update: the timeline

Here is every ranking update Google listed on its Search Status Dashboard during the period. Rollout times are the dashboard's own figures.

Google keeps the official list on its ranking updates release history page. For day-by-day coverage of each rollout, Search Engine Land and Search Engine Roundtable reported every one. Examples include the December 2025 core update, the March 2026 core update, the May 2026 core update and the September 2026 spam update.

The three Google core updates

Google describes core updates as "significant, broad changes to our search algorithms and systems", made several times a year. They "don't target specific sites or individual web pages". For all three core updates in this period, Google used the same description: "a regular update designed to better surface relevant, satisfying content for searchers from all types of sites". It didn't publish any new update-specific guidance.

That doesn't mean the updates were mild. Search Engine Land reported significant ranking volatility during the May 2026 rollout, with big movements on several days rather than just at the start. Search Engine Journal made the same point: a site that moved early in a rollout may need a different explanation from one that moved on the final day.

How Google says to assess a core update drop

Google's core update documentation gives a fairly specific process:

• Wait until the rollout is complete, then wait "at least a full week" more before analysing Search Console. Compare that week with a week before the update started.
• Separate small drops from large ones. For a small drop (Google's example is position 2 to 4) it says there's "no need to take drastic action". For a large drop (4 to 29), assess the site more deeply against its helpful content self-assessment questions.
• Avoid quick fixes. Google warns against removing page elements "because you heard it was bad for SEO", and calls deleting content "a last resort".
• Expect recovery to take time. Some changes take effect in days, but it "could take several months" for Google's systems to recognise site-wide improvements.

One useful addition came on 9 December 2025, just before the December update. According to Google's documentation changelog, the core updates page now explains that Google also releases smaller core updates that aren't announced. If you've improved your content, you "don't necessarily have to wait for a major core update" to see the effect.

The February 2026 Discover core update

This was the first core update Google has announced for Discover alone. In its Search Central blog post, Google said it would improve Discover by:

• "Showing users more locally relevant content from websites based in their country"
• "Reducing sensational content and clickbait in Discover"
• "Showing more in-depth, original, and timely content from websites with expertise in a given area"

Google also explained that expertise is judged "on a topic-by-topic basis". In its example, a local news site with a dedicated gardening section could have established gardening expertise, but a movie review site that wrote a single gardening article "would likely not". The update covered English-language users in the US, and Google said it would expand to other countries and languages later. We couldn't find any confirmation that this has happened yet. At the same time, Google revised its "Get on Discover" guidance, which now names clickbait and sensationalism explicitly and recommends a good overall page experience.

The four Google spam updates of 2026

Google runs automated spam detection all the time. A spam update is when it makes "notable improvements" to those systems, such as its AI-based system, SpamBrain. None of the four 2026 spam updates came with a named target. Google described the March and August updates as a "normal spam update" (as reported by Search Engine Land and Search Engine Roundtable). The March update finished in under a day, while the September update took almost two weeks.

Google's documentation says three things that matter if you're affected:

• Sites that violate its policies "may rank lower in results or not appear in results at all".
• Fixing the problem can help, but only after Google's systems learn "over a period of months" that the site complies.
• For link spam specifically, any ranking benefit from spammy links that's been removed "cannot be regained".

Policy and guidance changes alongside the 2026 updates

Some of the most practical changes in the past year weren't algorithm updates at all. They were changes to Google's written policies, listed on its documentation updates page:

What your content needs after the 2026 Google updates

None of these updates changed the basic test. Google's helpful, reliable, people-first content page is still the document it points site owners to after a core update. Read together with the newer AI optimisation guide, it suggests six priorities.

1. A people-first reason to exist

Google calls "why" content was created "perhaps the most important question". The answer should be that it's "primarily to help people". A good check from the same page: would your existing or intended audience find the content useful if they came to you directly, not through search?

2. First-hand experience and real expertise

One of Google's self-assessment questions asks whether content "clearly demonstrate[s] first-hand expertise and a depth of knowledge". Its framework for this is E-E-A-T: experience, expertise, authoritativeness and trustworthiness. Google says trust is the most important of the four. It also says E-E-A-T "itself isn't a specific ranking factor", but that its systems give even more weight to it on "Your Money or Your Life" topics such as health, finance and safety.

3. Original, non-commodity insight

The 2026 AI optimisation guide introduced the idea of "non-commodity content". Google contrasts a generic article like "7 Tips for First-Time Homebuyers" with an experience-led piece like "Why We Waived the Inspection & Saved Money: A Look Inside the Sewer Line". It also advises: "Don't just recycle what others on the internet have already said, or could easily be produced by a generative AI model." This is the same idea behind the Discover update's emphasis on "in-depth, original" content.

4. Clear, honest authorship

Google encourages accurate bylines where readers would expect them. It also warns that fabricated creator profiles, such as "AI-generated headshots, made-up names, or false credentials", are deceptive and make a page untrustworthy.

5. Accuracy, especially if you use AI

Google doesn't ban AI-assisted content. It says generative AI can be useful for research and for adding structure to original content. But it tells publishers to "manually factcheck and review all AI-generated content", including titles, meta descriptions, structured data and image alt text. Where readers might reasonably ask "How was this created?", Google suggests explaining how automation was used.

6. Honest titles and a readable page

Google's self-assessment asks whether a page title is a "descriptive, helpful summary" that avoids "exaggerating or being shocking", and the Discover changes point the same way. It also recommends clear headings, relevant images and video where they help, and a good page experience across devices.

What Google treats as spam

These are the practices most relevant to content publishers, as defined in Google's spam policies for Google web search. Sites that violate them can be demoted by automated systems or receive a manual action.

Warning signs that aren't spam but still hurt

Google's helpful content page also lists signs of "search engine-first" content to rethink. Examples include writing to a set word count ("No, we don't" have a preferred one), mainly summarising what others say, covering trending topics outside your expertise, and changing a page's date to look fresh when the content hasn't substantially changed.

What you can ignore for AI search

The AI optimisation guide is just as clear about what doesn't work in Google Search. You don't need an llms.txt file because Google Search ignores it. You don't need to break content into tiny "chunks" or rewrite it in a special style for AI. And seeking "inauthentic mentions" across the web "isn't as helpful as it might seem".

A practical checklist for your next post

• Can you say in one sentence who the post is for and how it helps them?
• Does it include something only you could say: a real example, result, process or opinion from your own work?
• Is it clear who published it, and is every factual claim accurate and, where useful, linked to its source?
• If AI helped, has a person checked every fact, title and description?
• Does the title describe the post honestly, without exaggeration?
• Are you publishing because your audience needs it, rather than to cover every keyword variation?
• Are any paid or sponsored links marked correctly, and do any guest articles stand on their own merit rather than just carrying a link?
• After any update, did you wait for the rollout to finish and a further week before judging the impact in Search Console?

Final thoughts on Google's 2026 updates

The past 12 months brought frequent Google algorithm updates but no change in direction. The core updates kept rewarding "relevant, satisfying content". The spam updates and policy changes kept targeting scale without value, borrowed reputations and manipulative links. The new AI guidance repeated the same advice: be original and people-first.

For most businesses, the most reliable source of first-hand content is the expertise they already share every day. If you regularly explain your work on camera, those videos already contain the experience Google's guidance describes, and writing them up as well-structured articles is one way to put it on your website.
