Core updates
Short answer: A core update is a broad change to Google’s search systems released several times a year; Google says it does not target specific sites, that most sites need not worry, and that a drop does not necessarily mean anything is wrong with the content. [1][2]
What is a core update?
Google says it makes significant, broad changes to its search algorithms and systems several times a year and calls them core updates. They are designed to deliver helpful and reliable results overall, and they do not target specific sites or pages.[1] It also says a page that moves down is not necessarily bad; there may simply be other pages that fit better.[1]
Which updates has Google recently announced?
Google keeps a dashboard of ranking updates. The entries below were listed when this page was written; the live dashboard is authoritative.[3]

How do I check whether an update caused my drop?
- Confirm the update has finished rolling out on the Search Status Dashboard and note its start and end dates.[1]
- Wait at least a full week after it completes, then compare a week of data with a week before it started.[1]
- Look at your top pages and queries. A small drop in position needs no drastic action; a large one calls for a deeper assessment.[1]
What if the drop is large?
Google recommends assessing the site as a whole, asking people unaffiliated with the site to help, and looking at the pages that were affected most. It warns against quick fixes, advises meaningful improvement of content, and says deleting content is a last resort.[1] If the page is hit by a spam update instead, the relevant material is on spam policies.
Do I have to wait for the next update?
Not necessarily. Google says improvements can show effect in a few days, but that it can take several months for its systems to confirm that a site as a whole is now helpful; if there is no effect after a few months, it may mean waiting for the next core update. Smaller core updates also run continuously and are not announced.[1] See recovery timelines.
Frequently asked questions
Is a core update a penalty?
Google describes core updates as broad changes to its systems, not actions against particular sites. A manual action is a different thing. [1][4]
Where does a spam update fit?
The dashboard lists spam updates separately from core updates. Google’s spam policies are what automated spam systems, including SpamBrain, enforce. [3][5][6]
