There are some really great books on seo available today, but there are not many on the single topic of Froogle. Froogle is Google's search shopping engine, it allows you to find products for free and list products for free. Froogle is not the most popular shopping search engines but its an important one to be a part of because of Google's current grasp of the search market and because Google has been featuring Froogle on many of its pages.
I had the opportunity to review an e-book named Froogle Maximizer. This is the first e-book, that I have seen, that discusses Froogle exclusively. Let me tell you that this e-book is a very comprehensive but easy to read book. It takes you through what Froogle is and is not and it then tells you what you need to sign up to Froogle. After you sign up, it takes you through the steps of setting up a feed and ensuring that feed works correctly - I learned a few things here that I did not know before reading this book. It even gives you detailed tips on how to optimize your feeds to rank in the top positions in Froogle, which is very important. If you can achieve on of the top three positions, you will most likely see a lot more traffic and transactions then from position four. This is because Google features the top three products from Froogle in the Google search results page when it matches a Froogle like search query.
I recommend taking a serious look at this e-book if your in the shopping search field. Find the e-book at http://www.frooglemaximizer.com/.
