I’m an old fart when it comes to landing pages. I started working with them way back in 2000 or so (gasp). So I can be a bit hard to impress.
MarketingSherpa’s Landing Page Handbook managed, though. It’s absolutely crammed with useful tips, factoids, research and best practices.
I didn’t quite sleep with it under my pillow, but it did end up on my nightstand for a few days.
The book covers the basics, such as landing page design best practices. It then moves on to more advanced testing techniques and provides a list of resources for landing page addicts like me.

A disclaimer: MarketingSherpa was kind enough to give me a copy for free. But that’s all they did. I get lots of stuff for free, like AOL subscriptions, catalogs, etc.. I’m not giving any of them a ‘thumbs up’ review. Trust me. This book is terrific.
