Google, in a rare move, pre-announced that they are going to be rolling out a core update tomorrow. They are calling this Google search algorithm ranking update the June 2019 Core Update and sometime tomorrow,

Google will be rolling this update out.

Danny Sullivan of Google said this specific update isn't particularly big or special, he said it is "Nothing special or particular "big."" It is just one of their regular core updates. The only reason they pre-announced it was to be nice.

As expected, Google told us yesterday afternoon that the June 2019 core update has started to roll out. It may take several days to roll out to all of Google's data centers but the process has started yesterday afternoon.

On Sunday

Google pre-announced this, which was rare, but they said they will be doing an update this week - a core update to the search ranking algorithms.

The June 2019 Core Update

Google said "The June 2019 Core Update is now live and rolling out to our various data centers over the coming days."

It will take at least the rest of the week for this to settle down. I am sure we will see plenty of theories before then and even after. But for now, let it settle, you will see pretty soon if you were impacted by this update and then you can start theorizing.

Many are already saying, even before it launched, that this was a rollback of some sorts.
