Ranking in Google Blog Search

In a thread in the Cre8asite Forum, they were looking at positive and negative things that can have an affect on your Google Blog Search Rankings. Among the positives he included were:

• Number of RSS subscriptions
• Clicks on SERP post links
• Blogrolls
• number of “high quality” blogrolls the blog is in
• ability for visitors to tag posts
• whether or not people are tagging them
• References to the blog by sources other than blogs
• Pagerank

Some negatives he mentioned:

• if posts come in short bursts or predictable intervals
• if post content differs from feed version
• If content includes a lot of spammy words
• duplicate content
• if posts are the same size
• Link distribution
• If posts mostly link to one site
