I have added a link to a new, free SEO ebook that is quite good to the list of SEO Scoop tools that you see in the navigation to the right of this page. Brad Callen wrote the ebook, and it is 90 pages of good solid information. It is especially helpful to newbies, but even an experienced SEO might pick up a tip that he or she hadn't thought of. It's totally free, so it's worth taking a look at.
One thing I noticed is that some people will get an error when clicking on the link that says "Error reading linearized hint data". If you get the error, you need to open your Adobe reader, go to Edit / Preferences, and find the Internet section. Uncheck the box that says "Allow fast web view". Close the reader and click on the link again, and your browser should open the ebook with no problem. Or, the other option is to just right-click the link and save the ebook to your computer.
