It may not be anywhere near as simple as all this, but:

I was able to secure 3 PR7 and 4 PR4 links to my "call to action" page on my newest website about 2 weeks ago. Since then, I've taken spots 9 and 2 for my 2 best key words on Yahoo, but still am only Indexed, but not PR'd by Google or in the top 200 for those same keywords on Google or MSN.

Is there a logical progression of events I should look for, or could I conceivably get #1 respect from Yahoo for all my keywords without showing up (except for my domain name) in the other 2?

I.e., does showing up in the SERP's usually take place in a specific order for the big 3?
