We know Trada’s readers are rabid for PPC knowledge. That’s why we gave everyone 10 PPC Experts to Know. Now we’re dropping a large blog directory so readers can gain additional PPC knowledge. The following blogs discuss pay-per-click (PPC) strategies of all levels from beginner to advanced, they offer breaking industry news, present case studies, track pay per click trends and more. Topics covered include ways to optimize Google AdWords, Bing, Microsoft Advertising, Facebook … and the list goes on.

Never-ending Blogosphere of Information
Blogs included here are all are updated relatively frequently and provide invaluable information about various aspects of pay-per-click advertising. Some of the PPC blogs listed may cover other topics as well as PPC, but their pay-per-click contribution is worth noting.
