Welcome to the Q&A Forum

I've endorsed Ryan's answer but just a quick note about PageRank. We encourage folks not to use PageRank as an indicator of ranking strenght, as "PageRank has a relatively low correlation to how well things actually rank." - Rand Fishkin PageRank is good for a couple of things, such as a raw indication of link popularity, or as Ryan mentioned to determine a penalty. PageRank data is historically inaccurate, Google doesn't update it regularly enough to be useful and finally Google has asked us politely not to scrape PageRank data, and SEOmoz honors that request. So those are a few of the reasons we don't include it in the MozBar (SEO Toolbar) and other places. Rand discusses the subject in depth in this WBF http://www.seomoz.org/blog/what-is-googles-pagerank-good-for-whiteboard-friday

Great suggestions, thank you!
