How to Track Google Search Engine Result Changes

There are many services that track changes in search engine algorithms. Most track Google, some track Bing and Google or other search engines. Below are the top SERP fluctuation trackers.

This is an often updated list of Google algorithm updates with explanations about them, who was most likely affected, and other details. It's not a detailed chart that shows SERP fluctuations as you'll see in other trackers below. If you are looking to understand the major algorithm updates in detail then this is a good place to start.
