Hey. I've been reading around about PPC spying tools, but I can't make a decision on which is best to buy. I've looked at ones like SpyFu, PPC Bully, and a few others, but I'm not really sure which will give me the best results - I've read mixed reviews about each here, some saying that the keywords were innacurate, others saying they weren't, etc. I was wondering if any of you guys could recommend one that you have had success with in the past? Thanks!
