Google changes its algorithm frequently and it is a very difficult task for marketers to know Google’s pattern of algorithm rollout.

Most of the updates released by Google throughout the year are minor updates that have a 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 decreases of many sites and even penalisation of some sites which goes against Google policy.
