I am noob in seo and also not in a position to spend money on some tools, so i wrote a shell script which monitors top 200 sites on a specific keyword for sserp rankings. So everyday i could see how each site was doing. I have site on that niche on 2nd page. Then one morning i found a completely new site appearing just below me, It wasnt on top 1000(a did a second check). After analyzing that site i was simply dumbfounded that it had only 7-8 backlinks and a few social likes, not a great site either.And now he ranks on 1st page. No updates seemed to affect him, any views ???
