In practice
The marketplace’s product is inventory: a searchable list of sites claiming metrics, priced and placeable in minutes — and its economics reflect that: the same inventory is sold to every bidder, the metrics are self-reported or tool-scraped without verification, the “relationship” is a ticket system, and the buyer inherits full responsibility for quality control.
That route can work for a team with its own vetting capacity buying commodity placements knowingly; what it cannot produce is the advantages that come from the direct route: publishers verified by a person who has read the site, prices negotiated against actual value, positions and anchors that get considered rather than accepted from a form, and — the compounding part — relationships that improve every subsequent placement (faster answers, better pages, honest rejections that save the pitch).
The risk profile differs too: marketplace inventories concentrate in exactly the sites that sell to everyone — the neighbourhood the guidelines’ pattern systems read — while a direct book of relationships is by construction more diverse and more defensible. The hybrid is honest where it appears: a team using marketplaces for discovery (finding candidate sites) but qualifying and negotiating directly (a person reads the site, a person makes the deal). The buyer’s diligence question: where does your publisher list come from, and who has actually read these sites — because the answer determines whether the campaign buys placements or buys listings.
