What is SEO for Firefox Measuring?

[Thomas L]

I've been using SEO for Firefox for a marketing assignment, but I've having some trouble understanding what some of the things that it's measuring actually mean and I can't find any resources on the subject. Specifically I need to know about "Traffic Value" and "Twitter". I'm guessing that they're rankings, but I just can't figure what they mean. Does anyone have any ideas?
Thanks,
Tom
