PRFilter, said to be the first press release search engine, indexes thousands of releases each day and is designed to save journalists and bloggers time.

Results are ranked based on a combination of relevance to the terms searched for and the number of people PRFilter’s patent pending Active Interest Technology considers a release to be relevant to. So the more people PRFilter thinks a release could be relevant to, the higher it is ranked.

Adam Parker, chief executive of RealWire, the company that developed the application, said: “In a world where relevance is increasingly at a premium we need tools that focus on increasing the signal to noise ratio, not simply amplifying it. PRFilter seeks to do this in a human way by basing its automated predictions of relevance on the topics that journalists and bloggers write about the most.”
