Andrew Goodman discusses the second edition of his book "Winning Results with Google AdWords" with Aaron Wall. Topics include what prompted the switch from publishing ebooks to print.
About halfway through the post, Wall starts asking about search-related subjects, such as when it make sense to create ads that get a high click-through rate, to predicting failed business models and staying competitive in pay-per-click for the long term. Goodman also divulges a PPC secret not shared before in a public interview.
