HubSpot has a Press Release Grader which could be a very helpful Internet Marketing tool. The Press Release Grader evaluates news releases and produces a report to help improve your PR program.
Thanks for mentioning Press Release Grader; we're so glad you find it helpful! I'd also recommend our Website Grader tool, which measures the marketing effectiveness of a website - http://website.grader.com.
Happy Holidays!
