Google confirmed Wednesday on Twitter that it released a “broad core algorithm update” this week. This was after the search community noticed shifts in rankings and traffic earlier this morning. Google will release several algorithm updates per year that it may confirm, while many others are not confirmed or recognized by Google.

Here is the tweet:

This week we released a broad core algorithm update, as we do several times per year. Our guidance about such updates remains the same as in March, as we covered here: https://t.co/uPlEdSLHoX

The March update and April update from earlier this year were also “broad core algorithm updates.” Google said its advice to webmasters on these updates has not changed.

Google will continue to refine its algorithms in order to make its search results better for their users. Google is telling webmasters that there is nothing a webmaster can do to “fix” their pages to rank better after an update. Instead, try to keep making your website better over time, and Google may recognize those improvements over time, and your rankings may improve.
