These answers cover using the guides.

About the channels and the methods, with AdBuyMCP as the worked example. Each guide is written so that a buyer using a different platform, an agency or a sales house directly still gets the useful part: what an audience pack is, why a power calculation has to happen before the flight, what a venue type claims and what it does not. Where the product's own behaviour is the point (an empty screen ranking, a refusal to report an underpowered lift), the guide says which behaviour belongs to this platform rather than to the channel.

Three places, and every guide names its own. Figures this site already publishes elsewhere (the plan's rate and entry prices, the fidelity bands, the supply grades) are quoted from the page that owns them. Mechanisms are described from what AdBuyMCP's software does. And market facts such as rate cards, minimums, clearance fees, market sizes and survey figures link to the page that published them, beside the claim, with the date each link was opened. A claim we could not find on its source was taken out.

They describe how each channel works and what AdBuyMCP does with it, so no figure in them is a campaign result. No media has been bought through AdBuyMCP yet. The supply page shows how far buying through each seller has been tested. The day counts in the lift-test guides are design inputs worked out from a formula, and the prices are worked examples from AdBuyMCP's plan pricing.

Yes. Nothing in them requires us: the geo-lift arithmetic works in a spreadsheet, the cinema calendar applies whoever books it, and the questions to ask an agent-operated media platform are worth asking of any vendor including this one.
