The best ways or medias that you have found to get the sit out there or get the buyers or sellers to view your site.

thats a great question. Seen agents spend zillions on sites just to have zero results. MANY of the sites agents make are for the sake of 1) doing because everyone else is 2) ego 3) because someone sold them. All of us are guilty to some extent.
Most agents would do just fine with just using whatever site their broker has. Beyond that the basic and enhanced realtor.com sites seem to offer some value.
Blogs will probably replace static sites for agents. A blog (like this one) gives value (hopefully) and motivates people to return to read whats new. A static agents site does not. Everyone offers buyers free home listings, everyone offers sellers free cmas. Blogs are perhaps the next step.
Here are things agents have done with some success to promote their sites. Not saying these things work but,.....here you go
1) google SEO or search engine optimization.
2) post cards
3) Signs of their for sale signs.
4) ads in general.
5) PPC and the like.

I have found the best way to drive traffic is thru targeted email blasting.

Hello,

The best way we ever came across to drive people to our site was simply having tons of listings.
Tons of listings = tons of buyer interest.

Most effective to least effective;
Most: On the for sale sign, part of the IVR recording, email blasts to agents who showed any of our listings in the past 24 months...they would often forward to their buyers, part of a just listed/ sold mailer, site url advertised on our past client mailings, url marketed on brochure box flyers for our listings. A GREAT place was craigslist.com, locally oriented websites (chamber site, community site)

For a while PPC was great, not so much now.

Least effective; PPC, adsense, any place we paid to have the link.

Hope this helps!
See you in San Fran at the Top Producer event!!
