Hi, 3 months ago my site is ranking in top 10 for my domain name. but now it is not seen in top 30 results. Let us explain it with example:- suppose my domain is abc.com. And i search my site writing "abc" it is no where in 30 results. Don't know why this happens. As my domain is "5 years old" and have good "PR & Backlinks". Right now i am not checking for other keyphrases for my site. I just want to come on my domain. I have modified my meta tags. added fresh content. But, no change. Too much worried. Need helpful suggestions..
