For those of you who aren’t familiar with it, I suggest taking a look at Grader.com, a tool provided by web marketing gurus HubSpot.
Their website grading tool provides a host of useful information that can help you fine-tune your site.
I’ve been playing around with their tools for the past few months, and they’ve been extraordinarily useful in terms of tweaking things to make them more search engine friendly. Also useful is their Twitter profile grader.
