Google announces June 2019 Core Update – rolling out now

In an unusual move, Google has pre-announced a broad core update to its ranking algorithm which is rolling out this week.

Previous 'broad core' updates have only been confirmed by Google after they were rolled out, such as in March and April this year.

However, Google opted for a change with this new update - deciding to pre-announce it on Twitter along with their previous advice about their algo updates:

They then confirmed yesterday that the update was rolling out:

Following speculation in the SEO industry that the June 2019 Core Update must be a big one if Google had chosen to pre-announce it, Google Search Liason Danny Sullivan said on Twitter:

However, that has not stopped the SEO industry from speculating about this update - both on how big of an impact it will have on the SERPs and what it will target.

Some early reports have suggested the June update may be a rollback of sorts on the March broad core update, while others have said they are seeing some recoveries on sites that were previously hit by the Medic update.

As the June core update has only just started rolling out, it is far too early to say for sure exactly what has changed.
