1. What is rel=nofollow, and should I add it to my links?
The nofollow tag (as it's commonly referred to), is an HTML attribute proposed by Matt Cutts of Google and Jason Shellen of Blogger.com in 2005. It is a recommendation on behalf of search engines to add a special identifier to links that shouldn't be counted towards search results. For instance, unmoderated blog comments might be a candidate for nofollow attribute. Read my post on nofollow

2. What are search engine friendly URLs?
Search engine friendly URLs, or tidy URLs as I prefer to call them, are well-formatted URLs. Tidy URLs are human-readable, easy for search engines to interpret, use minimal dynamic URL parameters, generally contain related keywords, and should be designed to be permanent whenever possible.
