The main purpose of all Press release services is to promote something significant and specific, and to do so clearly. Beyond that, a press release is a document that adheres to a strict format and serves three marketing and promotional purposes:

To notify the media about an event in hopes that they will spread the word.

To share something about your business, hope a reporter will see a story in your press release and write an actual news article about it.

To promote your business' appearance on the internet via blogs, websites, and social networks.
