About this site

Who

Built and maintained by Oliver Wakefield-Smith, founder of Digital Signet. One author, one desk, accountable for every figure.

Why it exists

Every CPV calculator we could find quoted uncited $0.01-$0.30 ranges; every benchmark post had no calculator. This site fuses the two: solvers whose defaults and verdict bands read from a single sourced ledger, so the tool and the evidence cannot disagree.

The no-naked-numbers rule

No figure renders anywhere on this site without a source, a URL, and a data vintage, enforced by construction: the calculators and the Benchmark Ledger read the same JSON file. Ad platforms price by auction and publish no rate cards, so platforms without a sourced band are labeled exactly that, never given an invented rate. Assumptions in worked scenarios are labeled as assumptions.

Refresh cadence

Bands are re-verified quarterly against their live sources, and the verification date on each ledger row is updated only when the source has actually been re-checked. Video pricing moves; a benchmark without a date is a rumor.

Corrections

Found a figure that does not match its source, or arithmetic that does not check out? Contact Digital Signet via www.digitalsignet.com. Corrections ship with a note in the ledger's refresh log.
