Backlinking in prep for PPC?



Yes this is a good idea. I helped a client set up a marketing campaign via PPC. The site was around for a while and had a PR score of 5. The QS got a big bump because of this (relative to them starting up anew).

I think nickycakes talks about this in his post about getting affiliate product blogs made.
 
Yes, it helps, but it's not gonna get you a .05 click, even at a Pr5...

Hint for high Adwords QS: The page the users go to when they click the ad should be 100% targeted to that specific ad. If your title says "Buy Discount TV's" and the LP doesn't have "Discount TV's" on it anywhere....

G rewards LPs that serve information equal to exactly what the ad copy says.
