Searching for knowledgable PPC information online can be a challenge because there is so much noise out there.
The idea behind our tool 'Better PPC Search' is to help analysts cut through some of the noise when doing PPC related searching. It's a Google Custom Search Engine that only returns results from PPC related sites and sources. Even broad searches like 'Excel' display results that would interest a PPC analyst. Hopefully it helps cut through some of the noise.
