One of my pages is lagging in the Google and Yahoo SERPS. I'm about to buy three text link ads. Two of them are from PR6 sites. They're both going to be pointing to:
http://www.preciousbedding.com/olymp...eets-c-28.html
The page with the "Olympic Queen Sheets" link is coming from a PR6 gamer's cheat-sheet page that has the word "sheet" written on it 100 times. The "Olympic Queen Bedding" link will be coming from a PR6 page that is covering news about the olympics, so it has the word "olympic" on it alot.
I'm also buying a PR4 link that's going to point to my main domain. That's also going to have the phrase "Olympic Queen Sheets" and is coming from another page with info about the Olympics.
So here's my questions:
How much should these links help me?
Is it going to help that the links are coming from the "Olympics" and "Cheat Sheet" pages instead of some page that's not related at all?
Does Yahoo have a system like PageRank for factoring the importance of a page and the importance of a link?
