Core Algorithm Update
For the first time, Google has informed via Twitter in advance that on June 3, 2019, the major Core Algorithm Update will be rolled out for June. A core algorithm update is run by Google a couple of times a year, but this time site operators were notified in advance.
Usually, Google updates without notice and then responds to requests from webmasters. Only in hindsight will the change be confirmed. It seems to be a response from Google on transparency requests from the community, that the group has now announced the date of the update in advance.
This also confirms Danny Sullivan of Google on Twitter:
Here’s an update about updates — updates to our search algorithms. As explained before, each day, Google usually releases one or more changes designed to improve our results. Most have little noticeable change but help us continue to incrementally improve search….

At what time is the Core Algorithm Update coming?
An exact time Google has not yet announced. If you want to stay up-to-date on the upcoming update at any time, you can keep an eye on the Google SearchLiaison Twitter account. If there is something new, it will probably be tweeted there first.
But what brings page operators now that they know about an update before? First of all, not much. The performance on Google with any changes can not be so easily influenced anyway. Only changes in the ranking behaviour or the visibility of a page can then be attributed to the Google Core Algorithm Update.
But no matter if there is a Google Update or not, for the SEO performance of every website, only constant optimization to the needs of Google is the key to long-term success. Only in this way can the top positions in the search engine be secured.
