What is a Google core update?
A core update is Google's name for a broad change to its core ranking systems, the technology that produces search results for every query. Google releases notable ones several times a year and posts their start and end dates on the Google Search Status Dashboard.
Core updates don't target sites or pages. Google describes them as reassessing content across the web as the web changes, so some pages move up and others move down without anything being "wrong" with the ones that fall. Its own analogy is a list of favorite restaurants written years ago: when you revise it, new places make the list and some old favorites drop down, even though they are still good.
What a core update is not
- Not a penalty. A drop after a core update isn't a manual action and has no reconsideration request. Search Console's Manual actions report will be empty.
- Not a spam update. Spam updates improve Google's spam detection and hit sites that break its spam policies; see spam update.
- Not the only change. Google says it also ships smaller core updates it doesn't announce, because they aren't widely noticeable.
- Not separate from helpful content anymore. Since March 2024, the systems Google used to call the helpful content system have been part of its core ranking systems.
Reading a rollout
Rollouts usually take days to a couple of weeks. Google recommends waiting until the update has finished, then waiting at least another full week before analyzing Search Console, and comparing a week after the update with a week before it started. Ranking movement during the rollout is often temporary.
Look at the size of the change. Google distinguishes small shifts, where it advises against drastic changes to pages that already perform well, from large, sustained drops that call for a closer review of the site as a whole. The step-by-step diagnosis lives in manual action vs algorithmic drop.
Responding well
Google's advice is to avoid "quick fixes" such as deleting page elements you read were bad for SEO, and to improve content in ways that help readers: rewriting, restructuring, adding first-hand detail. It calls deleting content a last resort. Recovery can take months, and some sites won't see it until a later core update. There's no guarantee any change brings rankings back, which is why the quality rater guidelines and E-E-A-T are useful lenses for a self-assessment.
Common questions
How often does Google release core updates?
Google says it makes notable core updates several times a year, alongside smaller core updates that aren't announced.
Can I recover from a core update?
Yes, but not with a quick fix. Improvements to content quality can take months to be reflected, sometimes only at the next core update.
Is a core update drop a penalty?
No. Core updates reassess content broadly. A penalty from a reviewer is a manual action and appears in Search Console.
