PitchEngine is a social platform to enable public relations pros to pitch their stories. Unlike traditional wire services, PitchEngine enables users to openly create and share their own content, while including images, videos and attachments .
You can try the service for free, but the basic plan is $39/month. Free would be much better.
Features of the tool include optimization for exceptional indexing in major search engines, ability to tag pitches with keywords, and ability to designate a tweet on each pitch.
I had the opportunity to look at the inner workings of this tool at the PRSA International Conference. The user interface was easy to use. It looks like a great tool to help get good visibility.
Other than the lack of a free basic package, the only other drawback I saw was the lack of metrics. I am told that this is in the works.
