Why don't you do some google searches for Realtor's in the area you are looking in. That should pull up those websites. You can take a good look at the sites and decide for yourself who to interview for the position of selling your home. Point blank ask them what their marketing campaign for selling your home is.
If you like I can give you a referral to a top agent in your area through the Realogy network. You can see all our brands and network. Only the top trained and certified agents can take referrals. So if you need one to add to your list of possibles just drop me a line.

Just know that most of the time the buyer first sees your home with a Realtor, so although Internet marketing is important, I would say on a scale of 1-10 it is a 7. There are a few things much more important that you should be looking for and asking about.
