What Is a Free Ad Network?

In programmatic advertising, an advertiser's money passes through intermediaries such as DSPs, exchanges and SSPs before it reaches the publisher. In 2020, ISBA and PwC traced a UK programmatic supply-chain sample covering 15 advertisers and 12 publishers: 51% of advertiser spend reached publishers and 15% could not be attributed to any step.^[1]

An independent site is too small to have leverage in that chain, as an advertiser or as a publisher. The free-ad-network approach is not to negotiate the take rate down but to remove the cash flow entirely. With no money moving there is no margin to split, no payment to settle and no minimum payout to clear. What you pay with instead is ad space on your own site.

If anyone could post infinite free ads, a network would rapidly collapse into spam. The foundation of a trustworthy barter network is a rigorous, balanced double-entry ledger.

In ADisAD, every single ledger posting must sum exactly to zero. You only earn exposure when your site contributes genuine Qualified Views, mathematically preventing fraud and inflation.

Mainstream ad networks track and profile individual web history across the entire internet. ADisAD operates with zero tracking cookies and uses salted, per-site fingerprint hashes, making cross-site identity tracking impossible. It matches strictly by context, not identity.
