The original announcement was made via the official Google SearchLiaison Twitter account the day before, on Sunday, June 2, 2019.

This is the official announcement of the Google Core update made the day before it went live:

“Tomorrow, we will be releasing a broad core algorithm update, as we do several times a year. It is called the June 2019 Core Update. Our guidance on such updates remains as we have covered previously.

The Google search link then linked to a tweet from October 11, 2018, called Update on Updates. In it, Google advises that there is nothing to fix in general updates.

Here's the important part of that multi-tweet guide:

“Sometimes we make broad changes to our core algorithm. We report on them because the helpful advice is that there is nothing in particular to “fix” and we don’t want content owners to mistakenly try to change things that aren’t problems…”

The reason they say there is nothing to fix is ​​that core algorithm updates may not typically be dj email list about specifically targeting low-quality content, but rather about improving relevance.

When you talk about content quality, you talk about spam. But showing users relevant results is about understanding search queries and understanding the content that excludes spam.

Broadly speaking, these types of updates are intended to improve the way Google understands search queries, improve the way Google understands web pages, and bring the two together to provide more relevant search results.

A side note on the “Penguin algorithm”
The Penguin real-time algorithm is a part of Google’s core algorithm. The “Penguin algorithm” deals with links.
