For each tracked keyword, the platform automatically builds a timeline of events that might have influenced its SEO performance. Following this timeline will help keep track of these events historically, as well as understand their correlation with the rank fluctuations of the keywords.
Here are the types of events already available in the timeline:
1. Landing page switches
Whenever a keyword's landing page changes, the event is registered in the timeline and most of the time it would also be followed by a rank fluctuation (the green circle in the image):

Landing page title or description changes are also displayed on the timeline:
Therefore you can A/B test with various versions of titles and/or descriptions and they will be automatically tracked in the timeline.
3. HTTPS migrations

4. Automatically discovered backlinks
Newly discovered backlinks in the Content Performance module are also marked on the timeline. Along the URL, you will also see the anchor text and the domain rating:
