If you’re an AdWords user, you could do a lot worse than to check out the WordStream blog and this article entitled AdWords Experts Share the Secrets of Their PPC Success–part 14! (Don’t worry: Links to the first 13 parts are conveniently provided.)
I love this part:
“In general, manual campaign management requires more hard work but in the long term rewards you with greater ROI in comparison with campaign management using automated tools in all levels.”
(Ad)Word.
Takeaway for marketers: Whether you’re implementing or overseeing AdWords campaigns, these articles are well worth your time. Read them.
