nice software , i tested it with a clients site and i would say its 90% correct , apart from the unique visitors search result. Apart from that looks good
I love it! I was wondering however how the algorithm calculates a website grade. I know math and numbers do not lie, but when I entered google and facebook they both showed a 67% grade. However, Twitter shows 70%. I am not sure if twitter is more effective than google as a marketing tool... or is it? If I get campaigns going on AdWords today, I can advertise to millions as long I have a budget to blow. On Twitter however, unless I have decent amount of followers (in the tens of thousands) I won't reach anybody whatsoever. And to get those followers it may takes months.
