In looking around I'm seeing those hippo vendor type advert boards you can rent and see one down side, showing in search. It doesn't. While seeing your ad on one of these boards and knowing the general public sees it, but ignores them for the most part, I have to ask.
Would it not be more beneficial to simple rent a 1 prim spot on peoples land to post your landmark giver and have it set to search? Would that not also count as an inbound link?
