This is my first post here. I have an ecommerce site that's actually on a Wordpress platform. It's my first foray into ecommerce so I'm starting small. I'd like to try PPC for it but my history with PPC is spotty. I've done a few campaigns but feel like I just don't know enough about it to have the best ROI. Since money is tight, I'm asking for a resource that can help me make the most ROI.
Please don't waste my time. I am not interested in an ebook written by some "guru" or a PPC course or membership site. I am looking specifically for a good book that has up to date information on how to do PPC . Any recommendations would be appreciated.
