There are countless Google algorithms that have been introduced in the last year or so, but a few of them have changed the landscape of SEO forever. The aim of Google is to update its search algorithm thousands of times during a year. In most cases, the algorithms of Google are too small to notice. But once in a while, Google introduces a change so fundamental that disrupts the manner by which we do SEO forever.
Core updates( 2017- till present)
Since 2017 Google starting referring to bigger updates as core updates of Google. Since that juncture, there is less transparency about what are those updates and which aspects of the search they intend to improve. It is very unlikely that the Google core updates are just improvements over the previous Google updates or the smaller updates aligned together.
As the effects of Google core updates are unknown, a thing that can be done is to track down the SERP history for the keywords you are targeting. The moment an update happens you can check with your competitors whether they have moved up or down in rankings and an educated guess can be made about the contributing factors.
For tracking your SERP history you may launch a rank tracker and go to targeted keywords.
