For some reason I am not ranking high for any keywords. 2 weeks ago I was ranking high for 1000's of keywords and I was getting 15,000 visitors a day. A week ago I noticed my ranks had decreased and I was getting about 10,000 visitors a day. Then just before the weekend my rankings have completely dropped off and I am getting just under 5000 visitors a day. I have not done any SEO changes / work at all and I cant believe my site is down by 10,000 visitors a day. Any ideas??
PR is just a Ranking status of the search engines it will be ranked according Content,Check your Bounce rate.Do you find any loss in Backlinks then your should really think serious.
Your sites need to being submit in all submission site continously and also keep watching in your compititors activities and it's back links SEO is the work in which you have to do it continousoly and do it smartly. You just start to increase the submission and grow of back links via link exchange. OR may be this happen by google dance.
