Google often releases core updates to its algorithm in order to either address a problem or to improve the relevance and quality of search results for users. With Google changing how its search algorithm works so frequently, there can be some disruptions to SEO. But how, exactly, do core updates affect SEO and what can you do about it?

Do Core Updates Change SERP Rankings?

The short answer is that yes, an update can impact your rankings. It doesn’t always; in many cases, rankings may stay the same if your content still meets Google’s requirements for high quality. However, because the core update may reassess what Google considers to be top quality, rankings may decrease or even increase, depending on how your content matches up with the new qualifications.

What Does It Mean If Your Rankings Decrease After a Core Update?

Each core update just means that Google is adjusting how it ranks content in order to better match users with the best possible search results. In some cases, you may have ranked higher on a keyword that didn’t quite match your content as well and now you rank better for other, more suitable keywords. In other cases, you may need to revisit your content quality and update accordingly to meet Google’s standards.

What Can You Do If Your Rankings Drop After a Core Update?

Whether there’s something you can do or not will depend on the core update. If there’s a specific action you can take to restore your rankings to what they were before the update, Google will let you know. For example, when it switched to mobile-first indexing, optimizing for mobile devices first was something Google announced that you could do to improve your rankings. Sometimes, however, there’s nothing specific and Google will announce that along with the core update.

What Should You Do If There’s Nothing To Fix After a Core Update?

If Google has announced that there’s nothing to fix after a core update, then you should focus on improving the quality of your content and your website. This can mean focusing on EAT principles in your written content as well as improving the technical SEO on your website for things like loading speed.

Do Google Core Updates Cause Ranking Volatility?

It’s possible that a core update could cause volatility in the search rankings as the algorithm adjusts to the new criteria. Rankings may not stay static and may change multiple times during the weeks that the update is being rolled out. If in the immediate aftermath of an update, your rankings aren’t what you’d expect, don’t panic. It may take some time for the rankings to settle after the gradual rollout of the update.

Can You Anticipate a Core Update’s Ranking Changes?

There’s no real way to anticipate the changes that Google will make ahead of time. However, there are things you can do to future-proof your SEO. Focus on producing quality content that will benefit and engage your users. If users find your content genuinely useful and keep coming back to it, then your rankings may more easily recover or may not be affected at all by an update. You should also regularly revisit your technical SEO to make sure that your site is keeping up with current expectations for load speed.
