Google is updating the way they generate web page titles – Tuesday, August 24, 2021.

Google announced a change to their system in the way they will generate and consider title tags for their users on August 24th 2021.

Previously, Google Search Console would generate title tags based on the users query in a search engine. This is no longer the case.

Google states:

How titles are generated 

Last week, we introduced a new system of generating titles for web pages. Before this, titles might change based on the query issued. This generally will no longer happen with our new system. This is because we think our new system is producing titles that work better for documents overall, to describe what they are about, regardless of the particular query.

Also, while we’ve gone beyond HTML text to create titles for over a decade, our new system is making even more use of such text. In particular, we are making use of text that humans can visually see when they arrive at a web page. We consider the main visual title or headline shown on a page, content that site owners often place within <H1> tags, within other header tags, or which is made large and prominent through the use of style treatments.

Other text contained in the page might be considered, as might be text within links that point at pages.
