Google Panda was initially launched in February 2011 as Google’s algorithmic response to poor quality and duplicated content sites which had gained high rankings in the search results.

Due to this Panda algorithm the small businesses were particularly the most affected. It greatly decreased their search visibility when compared to larger or well-known brand sites which Google seemed to favor more. One such example is for product related searches where sites like eBay and Amazon or other large retailers dominate the search results and smaller sites from the same niche can’t compete even if they offer good prices or better services.
