While many PPC Podcasts are in interview format, we'll be taking more of an investigative look at key themes in the world of Digital Advertising in our Core episodes. Episodes will be split into Core episodes with a journalistic approach and production, and Bonus episodes with an interview format of the experts used in each Core episode. Taken from the chapters of Kirk Williams' (PPCKirk) book: Ponderings of a PPC Professional, much has already shifted in the PPC landscape, and we'll interview smart PPCers and dig into themes in a fresh way to give you an insightful and interesting look at the changing world of PPC Marketing.
