Features

BlogPulse permits searching of the past six months of blog posts. Beyond the searching, there are some useful tools here:
As a blog search engine, BlogPulse can be used to do a search of just blog posts. Bloggers can ensure their posts are being indexed and find out how they rank against other bloggers. Public relations or media relations practitioners can use BlogPulse to learn about the buzz around any brand or company they represent. It is also an effective research to find out what trends people are paying attention to.
