How long on average before a backlink is counted on Google, I have over 200 links in MSN, however only 13 on google.
Your 200 backlinks might have been already indexed by Google but ... Google doesnt show all the backlinks. For example i got 40k BL's on Yahoo but only 3030 BL's on Google.
It is hard to say,you should add more high pr site links,maybe your site will be update by g about 1 month.
Has nothing to do with it. They will use the new backlinks shortly after they find them. And as Crazyhorse mentions, they only report a sample publicly so don't think the rest isn't being used yet. Normally, when I make a new Co-op ad I will rise in rankings in G within a week.
