Google Core Updates: What They Are and What to Do When One Hits
Updated: 5 days ago
By Spencer Capron, founder of Capron Media. Updated October 30, 2026.
A Google core update is a broad change to the systems Google uses to rank search results. Google runs several a year and announces the broad ones on its Search Status Dashboard. A core update is not a penalty and does not target any one site. If your traffic dropped, wait for the rollout to finish before you change anything.
What is a Google core update?
A Google core update is a broad revision of how Google judges which pages best answer a search. It does not target specific sites or pages. Because the judgement changes, positions shift, and a page that has not changed at all can move up or down. Most sites will not notice one.
Google's own comparison is a list of the best restaurants in town written a few years ago. Rewrite it today and some places move down, not necessarily because they got worse, but because new places opened and others were rated again.
A core update is | A core update is not |
A change to how all pages are judged | A punishment aimed at your site |
About relative position: someone else may now answer better | About one single factor you can fix in an afternoon |
When it is a broad one, announced on Google's dashboard with a start date | Something with an appeal process or a message explaining it |
How often does Google release core updates?
Google releases a core update a few times a year. Counting Google's own Search Status Dashboard on 30 October 2026, there have been nine core updates since March 2024: four in 2024, three in 2025 and two so far in 2026. Most took between 12 and 24 days to roll out.
Core update | Started | Rollout took |
May 2026 core update | 21 May 2026 | 11 days, 21 hours |
March 2026 core update | 27 March 2026 | 12 days, 4 hours |
December 2025 core update | 11 December 2025 | 18 days, 2 hours |
June 2025 core update | 30 June 2025 | 16 days, 18 hours |
March 2025 core update | 13 March 2025 | 13 days, 21 hours |
December 2024 core update | 12 December 2024 | 6 days, 4 hours |
November 2024 core update | 11 November 2024 | 23 days, 13 hours |
August 2024 core update | 15 August 2024 | 19 days, 4 hours |
March 2024 core update | 5 March 2024 | 45 days |

What was the latest Google core update?
The latest Google core update is the May 2026 core update. It started on 21 May 2026 and took 11 days and 21 hours to roll out, according to Google's Search Status Dashboard as read on 30 October 2026. Google has run three spam updates since then, which are not core updates.
When the next core update starts, it will appear on the dashboard first.

How do I know if a core update hit my site?
To check whether a core update hit your site, wait until Google's dashboard shows the rollout finished. Then wait at least one more full week. In Google Search Console, compare that week with a week before the rollout started, and look at which pages and searches lost clicks and position.
Confirm the update finished, and note its start and end dates.
Wait at least a full week after it ends.
In Search Console, open Performance and compare the week after with a week before the start.
Judge the size of the drop. Google's own example of a small drop is a page moving from position 2 to 4, which needs no drastic action. A drop from position 4 to 29 needs a closer look.
Check web, image, video and news results separately, because they can move differently.
Was it the core update, or something else?
A traffic drop during a core update is not always caused by the update. Before blaming it, rule out the ordinary causes: pages accidentally blocked from search, a broken redirect, a site problem, a recent rebuild, or the normal seasonal dip for your business.
If the drop followed a site rebuild rather than an update, the cause is more likely in the redesign mistakes that destroy search rankings.
How do I recover from a Google core update?
To recover from a Google core update, find out which pages lost, then make those pages more useful than the ones now above them. Read each one as a stranger would. Improve it, restructure it or rewrite it. Avoid quick fixes, and treat deleting a page as a last resort.
Wait for the rollout to finish. Positions move throughout it, so reacting mid-rollout means reacting to a state that has not settled.
Find out exactly what dropped: which pages, which searches. A site-wide decline and a decline on one section are different problems.
For a large, site-wide drop, use Google's self-assessment questions on helpful content across the whole site, not just one page. Ask someone you trust who has no stake in it to read the pages too.
Read the pages that now rank above yours. Do they answer the question faster, more completely, or from real experience?
Improve the page rather than delete it. Rewriting or restructuring keeps the address and its history.
Change one thing at a time where you can, so you can tell what helped.
How long does it take to recover from a core update?
Recovery from a core update can take months. Google says some improvements show within days, but it can take several months for its systems to confirm a site is helpful over the long term. If months pass with no change, you may need to wait for the next core update.
Google also says smaller core updates happen without an announcement, and they can lift content that has improved. That is one more reason to keep improving rather than wait for a date.
What not to do after a core update
After a core update, the fast moves are the risky ones. Do not make many changes at once, buy links, republish everything with a new date, or delete pages in a panic. Each one either hides what helped or creates a real problem where there was only a ranking change.
Do not make many changes at once. You will not know which one helped or hurt.
Do not buy links in response. It can turn a ranking drop into a real problem.
Do not republish everything with a new date. Changing a date is not an update.
Do not delete pages in a panic. The instinct is strong, and Google calls deleting content a last resort.
Is a core update a penalty?
No, a Google core update is not a penalty. A penalty, which Google calls a manual action, is applied to a specific site for breaking its spam policies, and it appears in the Manual actions report in Search Console. A core update changes how every site is judged, and sends no message.
If you dropped in a core update, nothing was done to you specifically. Someone else was judged a better answer for those searches.
How is a core update different from a spam update?
A core update changes how Google judges quality across all pages. A spam update strengthens Google's systems that catch pages breaking its spam policies, such as scaled content abuse, where many pages are made mainly to manipulate rankings. Both appear on the same Google dashboard, so read the name before you react.
Google introduced three spam policies alongside the March 2024 core update: expired domain abuse, scaled content abuse and site reputation abuse. Scaled content abuse is worth knowing now that making pages is nearly free.
Did Google say 40% of websites would be removed?
No. Google said the March 2024 core update, with its earlier work, was expected to reduce low-quality, unoriginal content in search results by 40%. On 26 April 2024 it reported 45% less of that content. That is a claim about what fills results pages, not about websites being removed.
This page used to carry a headline saying up to 40% of websites could be affected or removed. That was wrong. We corrected it rather than deleting it, and its old address now leads here, because that is Capron Media's policy: fix the page rather than delete it.
What to do between core updates
Between core updates, the steady work matters more than any reaction to one. Keep pages useful, current and clearly about one thing each, and read your Search Console data every month. What that looks like week to week is covered in Capron Media's guide to ongoing SEO.
