If you want to see a writer's great web site, check out particiacornwell.com. To be honest, I'm not a fan of forensic crime novels (too gory for my taste), but I do admire this site! As you'll see, obviously a lot of money has gone into it, but I think there are some elements that those of us who don't have a huge budget for a site could learn from.
One is her 'forensic challenge'--is there a way to make your site interactive?
Another is the variety of clips of her being interviewed or speaking. OK, these look like they were professionally recorded, but if what you are saying is interesting, even something recorded on a webcam can help attract people.
I'm in the process of designing the site for my forthcoming "Your Writing Coach" website, and I'm going to try to learn something from this site--have a look for yourself, you might find some inspiration there, too.
