So far, 2015 has been a challenging year for the search engine optimization industry. Two major updates were released this year one is mobile friendly update on April 21, 2015 and the slowly rolling out Panda 4.2 update released on 18 July 2015. Both of these updates have caused damage to some websites that lack mobile version or duplicate content. In addition, those websites that had reviewed and improved their On-page strategy after Panda 4.1 had a spike in organic traffic. Similar is the case with mobile friendly update.
