PageRank
PageRank is an important consideration in SEO, however don’t get caught up in it.
PageRank is just one small piece of the SEO puzzle, being a Google-specific link analysis algorithm in its own right.
Google explains PageRank in their Technology Overview, as well as the life of a Google Query. This makes for great reading, and will help you grow your SEO understanding. I highly recommend checking it out.
So yes, PageRank is a factor in your SEO efforts, but it’s definitely not everything. Understand what it is – perhaps even track it – and then move on, to more important on-page and off-page SEO factors.
