How easy/hard is it to get started with PPC? I want to try to promote my site on PPC and hope to get some targeted traffic. Are their any 'smarter' yet inexpensive ways of going about it? How about those Bing and Adwords coupons? Is it possible to be sneaky and just keep on using them? I've been reading around and it seems like it's quite difficult to do Adwords/Bing PPC now as they keep closing the accounts. Is that true?
