Google changes it algorithm frequently and it is a very difficult task for marketers to know the Google’s pattern of algorithm roll out.  Most of the updates released by Google throughout the year are minor updates which have lesser impact on search queries and affect lesser sites throughout the world. Google occasionally releases major algorithm updates which have a bigger impact on search queries causing rank decrease of many sites and even penalisation of some sites which go against Google policy.

It is surely a critical thing to know the pattern of Google’s algorithm updates and changes, but keeping the track of Google’s algorithm updates history can help you to get perspective on the rank fluctuations and organic website traffic, ultimately you can recheck your SEO strategies and improve search engine optimisation of your website.

To help you keep track of all minor and major algorithmic updates by Google, we had a deep research on this and documented the major and minor SEO updates and changes that was confirmed by Google. However, some for the changes were not confirmed by Google, but some webmasters noticed sudden drop in their website rankings and some experienced ranking fluctuations which made them sure there was some changes or updates done by Google behind the curtain.

Now, let’s go through all the major and minor Google algorithm updates.

People did see fluctuation in their rankings but in overall, nothing major effect were seen.

The next change is Penguin is now more granular. Rather affecting the whole website, it devalues the spam adjusting ranking based on spam signals.
