Want to see Google Algorithm Updates on Search Console data?
SEOTesting now displays them on the main site dashboard, page and query level.
On the main site dashboard GSC data can be grouped into weeks/months which can help show significance of updates.
Page/Url details view displays the updates as well
As does the query details view
There's a setting at website/user level whether to display these annotations by default, and you can then toggle them on/off each time.
