I have a new site (just over 3 months old) and after a month or so, it started ranking for some searches in Google.Then suddenly after 2 months, boom, no traffic coming from search other than when people search for the name of the site.My question is whether this is something common? I was doing some link-building, but nothing too out of whack. I did 2 guest posts on some blogs. 
Site got taken out of the search engines almost entirely
