Google Core Update History — Every Update and What Each One Changed

The latest confirmed Google core update is the May 2026 core update, which rolled out from May 21 to June 2, 2026. The most recent algorithm update of any kind is the September 2026 spam update, which began on September 24, 2026. Google confirms both on its Search Status Dashboard.

Key takeaways

• Google has run two core updates in 2026 so far (March and May), plus a Discover-only core update in February and four spam updates.
• 2025 had three core updates: March, June and December. Recent rollouts have taken roughly 12 to 18 days.
• Core updates reassess content quality across the web. They don't target specific sites, and there's no single fix for a drop.
• Google says to wait at least a week after a rollout ends before judging the impact, then compare before and after in Search Console.

This page is my running record of every Google core update, with dates taken from Google's own Search Status Dashboard. I update it whenever Google confirms a new ranking update, and each entry links to my full analysis where I've written one.

Latest update (kept current)

Latest core update: May 2026 core update. Started May 21, 2026; finished June 2, 2026 (about 12 days).

Latest algorithm update of any kind: September 2026 spam update. Started September 24, 2026, released globally in all languages. Google said it could take up to two weeks to complete.

Last checked: September 29, 2026.

Between confirmed updates, you'll still see volatility. The most talked-about example this year was the unconfirmed shake-up around July 11, 2026, which the SEO community nicknamed the "7-Eleven" update. Google didn't confirm it. I covered what I saw in my 7-Eleven update analysis.

What is a Google core update?

A Google core update is a broad change to the systems Google uses to rank search results. Google describes it this way: "Several times a year, Google makes significant, broad changes to our search algorithms and systems." It adds that these updates "don't target specific sites or individual web pages" (Google Search Central).

That distinction matters. A spam update targets specific policy violations like link spam or scaled content abuse. A core update re-evaluates how well pages meet searchers' needs across the whole index. Your pages can drop in a core update without breaking any rule, simply because Google now judges other pages as more useful.

Google also runs smaller core updates that it doesn't announce, because "they aren't widely noticeable". So not every ranking change you see has a name.

Here's how the main update types compare:

2026 timeline: every Google core update 2026 so far

These are the confirmed ranking updates for 2026, with dates from the Search Status Dashboard.

February 2026 Discover core update

This was the first core update Google announced for Discover alone. It launched for English-language users in the US, with Google saying it would expand to all countries and languages in the coming months. Google said the update aimed at "showing users more locally relevant content from websites based in their country", "reducing sensational content and clickbait" and "highlighting more in-depth, original, and timely content from sites with demonstrated expertise".

I covered that update in my February 2026 Discover core update guide.

March 2026 core update

Google's announcement used its standard description: "a regular update designed to better surface relevant, satisfying content for searchers from all types of sites." It rolled out in just over 12 days, one of the faster core rollouts in recent years.

May 2026 core update

Google used the same wording again and said it could take up to two weeks. It finished in about 12 days, with the biggest ranking swings reported by tracking tools around May 23 and May 30. I've covered the winners, losers and recovery steps in my May 2026 core update guide.

2026 spam updates

Four spam updates so far this year, most of them short. Spam updates are separate from core updates, but when they land close together it's easy to confuse which one moved your traffic. Check the dates in the table above against your own data before drawing conclusions.

For the most recent example, see my August 2026 spam update breakdown.

2025 and earlier: the full history

2025

All three 2025 core updates came with the same one-line description from Google about surfacing "relevant, satisfying content". What changed was pace: a long gap from June to December, then an 18-day December rollout that ran through the holidays. My December 2025 core update analysis goes through what moved.

2024

2024 was the most significant year for core updates in a long time.

March 2024 was the big one. Google folded its helpful content system into core ranking, and said the update and related work reduced "low-quality, unoriginal content in search results" by 45%. It launched alongside three new spam policies: scaled content abuse, site reputation abuse and expired domain abuse (Google). The 45-day rollout is still the longest on the dashboard.

August 2024 responded to complaints from smaller publishers hit in 2023. John Mueller said it took "into account the feedback we've heard from some creators", and Google said it wanted to connect people with high-quality sites "including 'small' or 'independent' sites".

November and December 2024 came back to back. The December update finished in about six days, the shortest core rollout listed on the dashboard.

2023

2023 also had the September 2023 helpful content update (Sep 14–27), which hit many independent content sites hard. Several of those sites are still the reference point in debates about whether later core updates "fixed" it.

2022

The first helpful content update also launched in August 2022.

2018–2021

Before the Search Status Dashboard started listing them in late 2021, Google announced core updates mostly through its Search Liaison account on X (then Twitter), and often didn't give completion dates. The confirmed broad core updates in this period were:

• 2018: March, April and August. The August 2018 update was nicknamed "Medic" because health sites saw big swings.
• 2019: March, June and September. June 2019 was the first core update Google announced in advance.
• 2020: January, May and December.
• 2021: June (Jun 2–15), July (Jul 1–12) and November (Nov 17–30).

What core updates reward

Google doesn't publish a changelog for core updates. What it does publish is guidance on what its ranking systems look for, and it points site owners hit by a core update to that guidance every time.

The core of it is Google's page on creating helpful, reliable, people-first content. Its self-assessment questions boil down to a few themes:

Original value. Does the content provide original information, reporting, research or analysis? Does it add something beyond rewriting other sources?

Experience and expertise. Is it clear who wrote it and why they're qualified? Does it show first-hand experience with the product, place or problem?

Satisfying the searcher. After reading, does someone feel they've learned enough to reach their goal, or do they need to search again?

Made for people first. Would your audience find it useful if they came to your site directly rather than from search? Content written mainly to attract search visits, especially at scale across topics you don't normally cover, is what Google's systems try to demote.

Presentation and trust. Is the page free of obvious errors, distracting ads and exaggerated headlines? Is it presented in a way that makes you want to trust it, with clear sourcing and evidence of expertise?

Looking across the history above, a few patterns hold:

• Google's own statements since March 2024 have focused on demoting unoriginal content and content produced at scale mainly to rank.
• Forums and first-hand discussion have gained visibility, with Reddit the most cited example in industry visibility data. SISTRIX data shows reddit.com's Google visibility rising sharply through 2024 and 2025 before peaking in October 2025.
• Recovery rarely happens mid-cycle. Many sites that dropped in one core update saw partial recovery only at a later one.

That last point is worth taking seriously when you plan your response.

The first 2 weeks after a core update: what to do

Every rollout brings a wave of "did anyone else get hit?" threads on Reddit. That instinct is understandable, but most of what people do in the first two weeks makes things worse: rewriting pages mid-rollout, deleting content in bulk, or buying links to "recover".

Here's what I do instead while an update is still rolling out:

• Week 1: observe. Annotate the start date in your analytics. Check the Search Status Dashboard daily. Don't change anything significant.
• Separate the signals. Check whether a spam update or a technical issue overlaps with the core update. A drop caused by accidental noindex tags or server errors looks similar in the traffic chart.
• Week 2: segment. Which pages, directories or query types moved? A site-wide drop is a different problem from one section falling.
• Wait for completion. Google says to wait "at least a full week after a core update completes" before analysing in Search Console.
• Write it down. Note what you see so you can compare with the next update.

How to recover from a Google core update

If you've waited for the rollout to finish and still see a significant drop, work through this in order:

1. Confirm it's the core update. Line up the drop with the rollout dates. Rule out technical causes with the Page indexing report and URL Inspection. My guide on why a website isn't showing on Google covers the checks.
2. Compare before and after in Search Console. Use the Performance report with a date comparison: the week after completion versus a similar period before the start.
3. Judge the size of the drop. Google's guidance says small moves (position 2 to 4, for example) need no drastic action, while big ones (position 4 to 29) deserve a proper review.
4. Find the pages and queries that lost most. Sort by click difference. Look for patterns: content type, template, author, topic, age.
5. Look at who replaced you. For your biggest lost queries, study the pages now ranking. What do they offer that yours doesn't: first-hand detail, better structure, fresher data, a different format?
6. Improve or remove weak content. Rewrite pages with genuine expertise and original detail. Consolidate thin pages that overlap. Remove content that exists only to catch search traffic.
7. Fix trust signals. Clear author information, about pages, sources for claims, fewer intrusive ads.
8. Be patient and keep publishing well. Google says changes "can take effect in a few days, but it could take several months", and you don't necessarily have to wait for the next core update. Track progress monthly with the SEO KPIs that matter for your site.

What not to do: mass-delete content without checking what it earns, change your whole site design in a panic, or buy links. None of those address what a core update measures.

Frequently asked questions

What is the latest Google algorithm update?

The latest confirmed update is the September 2026 spam update, which began on September 24, 2026. The latest core update is the May 2026 core update, which ran from May 21 to June 2, 2026. Google lists every confirmed ranking update on its Search Status Dashboard.

How to recover from a core update?

Wait until the rollout finishes plus a week, then compare Search Console data before and after. Find the pages and queries that lost the most, study what now outranks you, and improve or consolidate weak content. Recovery can take months and often shows at a later core update.

How often does Google release core updates?

Google says it makes broad core updates several times a year. Recently that has meant two to four announced core updates per year: four in 2024, three in 2025 and two so far in 2026. Google also makes smaller, unannounced core updates throughout the year.

How long does a Google core update take to roll out?

Core updates in 2025 and 2026 took roughly 12 to 18 days. The March and May 2026 core updates each finished in about 12 days. The longest on record is the March 2024 core update at 45 days, and the shortest recent one was December 2024 at about six days.

Is a traffic drop during a core update a penalty?

No. A core update isn't a penalty and doesn't target specific sites. It re-evaluates how useful pages are compared with others. Manual actions are separate and appear in Search Console's Manual actions report. If you have none, treat the drop as a relative quality issue.
