Why my site is droping in google just for 2-3 keywords .Did i do something wrong or google puting my site in objective place because is just 4 month old site and domain...thanks
its hard to say why your site is dropping in ranking. there could be many reasons but if you build a site and did some link building at the beginning, then stopped building links, that could be the reason. when you develop a site and build some backlinks, your site gets an initial boost in ranking due to fresh content. this initial boost in ranking however dont last long and you will find your site dropping in ranking within weeks. maybe thats whats happening. in order to prevent that from happening, you will need to keep up with the link building and don;t stop building links till you get a stable ranking without any google dance.
Well, the site is 4 months old, so its away from Google probationary period, now getting the result for your SEO. Better is update the site with unique and rich content frequently if possible daily. Also try to make some BL from quality sites.. check your site quality and make error free, for this can use Google webmaster tool and also many other SEO tools available...
It can be several factors, or another competitor trying to rank in that keyword has done more backlinking to out rank you.
