I have to agree with justmark as well. Way to often, I see people trying to compete with the big directories or Amazon (in the ecommerce sector). The harsh reality is, you can’t. As a viewer though, this is good because people are finding them outdated and lengthy. Find the niche. Who exactly is your advertiser and who is your audience? Once you have that pinpointed down, you have a much better chance at using GD to it’s fullst extent.
