Thankfully there are many of great eBooks out there that focus solely on SEO. These eBooks are all top sellers on Amazon and even checking out a few of their ‘Look Inside’ features and going over the first few pages could be a big help to you. And of course you can always pick up a copy of Write to the Top: How to Write Website Content that Google Loves. Alright, now that the shameless plug for my own book is over, let’s see what 5 other great SEO eBooks look like.
SEO 2013 & Beyond

It’s more targeted toward beginners, so if you’ve been in the business awhile you’ll want something a bit more meaty. The book clocks in at 88 pages, which is pretty short. Still, you’ll be getting quite a few new ideas, things that could give your site more traffic. And at just $3.99 you’re getting a pretty good deal.
SEO Made Simple

Michael Fleischner has been doing SEO for more than 15 years so it’s probably a good bet that he knows what he’s talking about. He’ll discuss the latest changes involving the Google algorithms as well as some good tips and tricks. Still, the book does contain several spelling and grammatical errors, and is primarily targeted at people new to SEO. If you’ve been doing it as long as the author has, you’ll probably want something else.
SEO Black Book

The book focuses a lot on white hat SEO and black hat SEO and how you can avoid the latter. It goes into detail on the Search Engine Results Page (SERP), as well as on what you need to do to give your site value besides just having products on it. A great SEO site can make you money just from your advertising content if you’ve got great content and great SEO. This book will help explain why and how to do that.
Search Engine Optimization Secrets

The book does a good job covering all of the SEO bases, and many reviewers agree that it’s one of the best. It’s a bit dated, having come out in March, 2011, so some of the information might not help you with the constant changes that Google is making. Still, if you’re looking for new ideas or a fresh take on old ones, this is a good book to check out.
SEO 2013

The book is good at grabbing your attention and keeping it, and with 112 pages priced at just $4.99, you’re really getting a good deal. SEO can be hard to understand at times even for someone who’s read these five books, but like anything in life, the more you practice, read about it, and implement it the better you’ll be. This book will do a lot in making you realize how you can do it.
