The OpenX alternative for vendor and marketplace directories
OpenX is a programmatic supply-side platform for large publishers. For vendor and marketplace directories selling to the listed vendors themselves, DirectoryAdServer is a directory-first ad server with sponsored listings, ad-buy packages, and flat-fee pricing that lets you keep every dollar of ad revenue.
The gap
Why OpenX isn't built for vendor & marketplace directories
OpenX is an auction-based exchange built for programmatic scale — it is the opposite of selling a handful of placements directly to local sponsors, and it takes a share of the demand it brokers.
A vendor directory turns its own vendors into recurring sponsors, so it needs scarcity — capped featured slots and waitlists — to drive upgrades and renewals. A directory serving buyers comparing vendors needs to sell featured vendor slots, category-top placements, and waitlists — and OpenX runs on revenue share on auctioned programmatic demand, which works against a directory selling placements directly to the listed vendors themselves.
