Want to know how to evaluate an agent based on his website? Writer Victoria Strauss does it by picking apart the website of an actual, new agent:

Under Most Recent Sales/Forthcoming Books, Mr. Santsaver lists two books and two screenplays, none of which can be found on Amazon.com, on publishers' lists of forthcoming books, in recent sales reports from sources like Publishers Lunch--or anywhere else. Sales that can't be verified are pretty much the same as no sales at all. (And yes, Mr. Santsaver's agency does appear to be new, and new agencies take a little while [though not longer than a year] to start making sales--but that brings us back to the need for a relevant professional background.)

It's fun and educational!
