These answers cover measurement and frequency.

Frequency is planned: each week we buy enough ads aimed at your market for it to see you that many times on average. Some of every channel's audience sits outside your market, and the weekly report shows what each channel delivered against the plan.

It shows what each channel delivered at the level that channel counts: places and times for billboards and screens, households for streaming TV, downloads for podcasts, and impressions and clicks for ChatGPT ads. None of them tells you who the person was, so the report can't name who saw you.

In aggregate, rather than sale by sale. A billboard has no click and a podcast download carries no buyer's name, so the routes are your own numbers, what new leads tell you, and a geo-lift test when your numbers can support one. ChatGPT ads count clicks and conversions, for that channel only.

Make sure you can see searches for your company name and direct visits in your own tools, and start asking every new lead where they first heard of you. A few weeks of those numbers before your start date give you something to compare the campaign weeks against.

The engine, its power check and both refusals are built, and today they run on labelled sample data. No media has been bought through AdBuyMCP yet, so the first live result will come from the first campaign whose numbers can support a test.

A brand-lift study asks a panel whether they recall you, comparing people who saw the ads with people who didn't. The product can scope and quote one through Cint, a research panel company, but no Cint contract is signed yet, so brand lift isn't part of a plan today.

Frequency is planned: each week we buy enough ads aimed at your market for it to see you that many times on average. Some of every channel's audience sits outside your market, and the weekly report shows what each channel delivered against the plan. No UK service de-duplicates frequency across channels, so the report shows each channel in its own units. Out-of-home: proof of play from the screen, and Route's modelled reach, impacts and frequency. Streaming TV: impressions and completed views, with reach and frequency by household within each seller. Podcasts: downloads and ad deliveries, counted from server logs to the IAB Tech Lab standard. ChatGPT ads: impressions, clicks, spend, click-through rate, cost per click, CPM and conversions. OpenAI reports no reach or frequency.
