I know that blogs are becoming a very popular traffic generating method, so perhaps I should reconsider and just offer them. I'm sure this marketing tool would work very well if you updated your tours regularly and created a blog entry with every update. I'm thinking you would be wasting your time if you were making blog entries and the pics used weren't even on the tour.
Becky,
I don't think the pics used need to be in the tour for it to convert. It will help if they see the same model, so they know the model they like from the blog is on the site, but showing the same exact pics would be overkill IMO. We do plan to correspond blog updates in our affiliate program with site updates.
