I recently heard about this cool little website, www.pressreleasegrader.com. According to them:
HubSpot’s Press Release Grader evaluates your press release and provides a marketing effectiveness score. This score is based upon basic factors from public relations experts including the language and content of the release, plus advanced factors from Internet marketing experts such as links and search engine optimization characteristics.
Also, it tells you if you have dumb marketing-speak words in the release that turn reporters off by offering a cool tool called Gobbeldygook Word Analysis. It automatically scans your press release for meaningless terms.
