Google Core Updates: What They Are, How to Check Impact, and How to Recover
Most sites don’t need to do anything after a core update. Here’s how to tell if yours does.
Several times a year Google makes significant, broad changes to its search systems, which it calls core updates, and announces them on its list of ranking updates. Google says they don’t target specific sites or pages, and most sites may not even notice one.
If your traffic changed around the same time, Google publishes guidance on how to assess it and what to do.
Short answer: Core updates are broad changes to Google’s ranking systems that happen several times a year. To check impact, wait until the rollout is finished and at least a full week has passed, then compare a week after with a week before in Search Console. Small position drops (e.g. 2 to 4) need no drastic action. For large, sustained drops, honestly assess your site as a whole against Google’s helpful content questions and improve content meaningfully; recovery can take months and sometimes another core update.
Key Takeaways
- Core updates are broad and don’t target individual sites.
- Wait a full week after the rollout ends before analyzing.
- Small drops: avoid changing pages that already perform well.
- Large drops: self-assess the whole site, not just a few pages.
- Avoid quick fixes; deleting content is a last resort.
How core updates work
Google compares a core update to revising a list of favorite restaurants: new options appear and some move up, so others move down without necessarily being bad. Rankings change because the systems reassess the web as a whole.
How to check if an update affected your site
- Confirm the update has finished rolling out on Google’s Search Status Dashboard, noting start and end dates.
- Wait at least a full week after it completes.
- In the Performance report, compare the week after with a week before the rollout started.
- Review top pages and queries: was the drop small or large?
- Look at web, image, video and news search types separately.
Small drop vs large drop
| Small drop | Large drop | |
|---|---|---|
| Example (Google’s) | Position 2 to 4 | Position 4 to 29 |
| What to do | No drastic action; avoid changing pages that perform well | Deeper assessment of the whole site |
Assessing a large drop
- Review the site as a whole against Google’s helpful content questions, as objectively as you can.
- Ask people you trust who aren’t connected to your site to assess it too.
- Look closely at the pages that were hit hardest. Are other pages doing a better job for those searches?
Making changes
- Avoid quick fixes like removing page elements because you heard they’re bad for SEO.
- Improve content in meaningful ways: rewrite, restructure, add first-hand detail and clearer answers.
- Treat deleting content as a last resort for content that can’t be saved. Google says needing to delete whole sections suggests they were made for search engines first.
How long recovery takes
Google says some changes take effect in days, but it can take several months for its systems to confirm a site is producing helpful content in the long term, and sometimes the effect shows only with the next core update. Smaller, unannounced core updates also happen. There’s no guarantee of recovery.
Frequently asked questions
How often does Google release core updates?
Google says several times a year, and lists them on its ranking updates page.
Did I get a penalty from a core update?
No. Core updates aren’t penalties; manual actions appear separately in Search Console.
Do I have to wait for the next core update to recover?
Not necessarily. Google says improvements can show sooner, including through smaller unannounced updates.
