What is an evidence ledger?
Free, with no card. We read your homepage, draft who buys from you and show your monthly price before you join the waitlist. Nothing is bought until you've approved the plan and the ads.
what it means here
Here is what the term means for a UK buyer
The definition above holds anywhere. Buying media in the UK adds the detail below, including where AdBuyMCP does something different.
It lets anyone check AdBuyMCP's supply claims connector by connector. A client that has been written shows that the code exists, and says nothing about whether a vendor accepted a request, spent money or returned real delivery, which is why each grade is set by what the vendor has done. Of the 26 registered connectors, 22 are client-built, 3 are stubs that make no vendor call at all, and 1 has had read-only calls accepted by a live vendor. Nothing has reached spend-tested or report-verified, and the ledger keeps those two grades empty until a connector genuinely earns them.
Type your company website or work email to see who we think buys from you and what reaching them 3, 5 or 12 times a week would cost.

These terms sit next to this one
Most confusion in media buying comes from two adjacent terms being used interchangeably, so these are the neighbours worth reading next.
Evidence provenance
A label attached to a number recording how it was produced, so anyone reading the number can see how strong the evidence behind it is. The number may be reported by the seller, observed on your own property, estimated by a model, or established by a powered experiment.
Insertion order (IO)
A contractual document committing an advertiser to buy specified advertising from a specified seller at agreed terms. The mechanism by which media that is not bought programmatically is bought instead.
Programmatic advertising
Buying advertising through automated systems that decide, impression by impression, whether to bid and how much to pay for it. It describes the transaction mechanism rather than a channel: CTV, audio, DOOH and display can all be bought programmatically.
