In probably the most important search ranking news in 2010, Ben Hendrickson of SEOmoz announced his findings yesterday at the SEOmoz PRO conference in Seattle.

He's discovered that LDA for a page vs. the search keywords has a higher correlation with rankings in Google than the number of unique IP addresses or unique domains linking to the page.

LDA (Latent Dirichlet Allocation) is a measure of how relevant a page is to a given search phrase by analyzing how often the search phrase is seen in documents that also contain elements of the text on the target page.  

This is earth-shattering news for the SEO community, as his findings indicate that real relevance of the on-page text to the search phrase is more important in the Google search ranking algorithm than links or anchor text.
