2, blog posts how old and the latest message situation. If this blog post is three years ago, and a year without new messages, suddenly a large number of messages, suspicious.

3, message relevance. Search engine can judge the relationship between the message and the blog post through Semantic analysis. For example, my blog, in the Wandering blog management backstage There are a lot of such unrelated messages.
