PR Filter from Realwire finds press releases for journalists and bloggers based on the content that they’ve published online. It’s a bid to kill PR spam.

When I log in a web page displays relevant press releases from all the major wire services (BusinessWire, Marketwire, Realwire and Sourcewire etc) and major media and technology web pages.

This week PR Filter added a search function to the platform to enable anyone to search its firehouse of 15,000 press releases per week.

I caught up with Realwire boss Adam Parker (@aparker) today and asked him what lay behind this development behind this development.

“The feedback we got from the initial test phase of the personalised filtering was that many people needed to first be comfortable with the sort of results the system could provide.”

“Also the need to be registered with the site, though clearly necessary in order to produce personalised results, was unintentionally restrictive.”

“The public search functionality removes these barriers so everyone can gain an understanding of how PR Filter could potentially assist both the PR and media communities to find relevant stories.”

The public search function could help journalists and bloggers to find relevant stories but could also be a useful research tool for PRs as well to see what press release content companies are pushing out on a topic on any given day.
