The weighting of back links appears to have been reduced while the weighting of on page factors appears to have been increased. Many agree that Google has been using Latent Semantic Indexing (LSI) in it’s algorithm for quite some time, but in this recent change LSI appears to play more of a role in relevancy scoring. In general terms LSI allows for a better understanding of keywords within the larger collection of content on the page.

The use of the Page Critic module in WebPosition has become even more important with this apparent ranking algorithm change.
