Hello Webmasters, I have been the webmaster of a blog http://tech2auto.in/. The site is 7 months old. It was getting 6-7k UV per day since last three months. No Black hat method, simply published original content, built few genuine back links. Not too much of SEO done. In past seven days traffic dropped significantly. All the keywords driving traffic suddenly disappeared. Traffic dropped 66%. Consistently loosing SERP. New posts are getting indexed in no time but nothing improving as per as SERP is concerned. It was getting 75% search traffic but now it's dropped to 70%. Major keywords are all gone. Posts are original and targetted to a specific audience. What should I do at this point of time? Is there any flaw you have figured out? Any idea is highly appreciated. N.B. Please don't post reply here just to increase your post count.
