Google is releasing a broad core algorithm update later today on June 2, 2021.
This will be followed by another core update in July.
Google offers the following information:
“Some of our planned improvements for the June 2021 update aren’t quite ready, so we’re moving ahead with the parts that are, then we will follow with the rest with the July 2021 update. Most sites won’t notice either of these updates, as is typical with any core updates….
Of course, any core update can produce drops or gains for some content. Because of the two-part nature of this release, it’s possible a very small slice of content might see changes in June that reverse in July….
As a reminder, nothing in a core update is site-specific. Those who seek to perform well with search generally, including with core updates, should look to our guidance here.”
In addition, Google has published a blog post with details on how search is updated thousands of time per year with changes meant to improve the experience and quality of results.
