i am running a weight loss pills review site at http://www.blemos.com. i am targeting for the keyword "Weight Loss Pills". So i started getting backlinks and my site got 160th position for the keyword "weight loss pills" 1 week before. for last 3 days i got more than 10 High Page Rank backlinks. But there is no increase in my site rank, it got decreased and now it is in 180th position. I even submitted the pages which i got backlinks to digg, but also my rank won't got increased. what is the problem ?????
Probably the high page backlinks you got were not yet indexed by Google - this usually happens if you sent the links to directories and such: a longer period of time passes until the link back is recorded.
pages submitted in digg will get indexed faster ( within 4 hours ). i submitted the pages where i have got links in digg and even in delicious. so i think it will get indexed, but i don't know really weather it got indexed or not.
