Why do blogs perform so well in the search engines?
Blogs perform well in the search engines for several reasons. First of all, blogs are updated regularly with fresh keyword rich posts. The posts tend to be centered around just a few major themes, making the entire blog strongly themed for those keyword phrases. Incoming links from the vast majority of other blogs and websites share that same theme, providing the blog with the full power of their link popularity boost and Google PageRank transfer. Links from within the posts on other blogs are not only powerfully theme related, but often contain some desirable keyword laden link anchor text.
