FAQ
Does "on both" mean the same seller?
Not necessarily — a domain can be listed on both marketplaces by the same publisher or different resellers. What's shared is the placement opportunity, which is what you dedupe before buying.
Is a bigger database always better?
No. Overlap, price spread, DR/traffic quality and geography decide value for a specific campaign. Comparing databases is how you buy the same link for less and find inventory a single platform can't offer.
