This one is specific to Google Blog Search which is a separate one from the main Google Web Search. Via Steve Rubel, Google Operating System writes an explanation on how a blog post or blog entry is ranked:
Positive signals
* links from blogrolls (especially from high-quality blogrolls or blogrolls of “trusted bloggers”)
* links from other sources (mail, chats)
* using tags to categorize a post
* PageRank
* the number of feed subscriptions (from feed readers)
* clicks in search results
Negative signals (spam signals)
* posts added at a predictable time
* different content between the site and the feed
* the amount of duplicate content
* using words/n-grams that appear frequently in spam blogs
* posts that have identical size
* linking to a single web page
* a large number of ads
* the location of ads (“the presence of ads in the recent posts part of a blog”)
I’m surprised that feed subscription is part of the positive factors. Again, the number of ads that you put into your blog is also considered — now that’s a nice way of balancing content and advertising. We all know money is the single biggest reason why spam is still growing (could be a multi-million dollar industry).
