On the marketplace, Amazon already knows. Everywhere else, nobody does.

A large part of what this platform sells is advertising that ends in a purchase on the marketplace, where the platform observes the transaction itself.

There is nothing useful to add there, and a page claiming otherwise would be selling a solution to a problem that does not exist.

What it cannot see is the campaign that sent somebody to your own site, your showroom or your phone line, because the sale then happens in a system it has no access to.

That gap is the only thing this page is about, and being specific about it is more useful than implying the tool covers the whole account.

An advert seen during a programme is closer to television than to search: nobody clicks, and the effect appears days or weeks later as somebody arriving by name.

Measured on click-through behaviour, that inventory reports almost nothing, in the same way television always has.

Matching enquiries to sales over a longer window at least puts the revenue in the right period, and the report groups by when the enquiry arrived rather than when the money did.

It will not manufacture a link for somebody who never identified themselves. What it will do is stop the revenue being credited to whichever channel they used to reach you afterwards.

This is the one channel in this catalogue where the lead file cannot come from the advertising platform at all, because the platform does not hand over contact details.

A distinct landing page, a distinct tracked number, or a campaign parameter written onto the enquiry record — any one of those creates the file. None of them is expensive.

Where none exists, every enquiry this channel produced lands in Direct / Unknown, and the report will say so rather than distributing it across the channels that do have data.

That statement is itself the finding for a lot of accounts, and it is worth having before the next budget rather than after it.

The two have different margins, different data and different strategic value: one builds a relationship you own and the other builds one the marketplace owns.

Adding them produces a total that flatters the channel and answers no question anybody is actually asking.

The report covers only the second, and says so on every figure, so the number can sit beside the platform's own marketplace reporting without pretending to replace it.

Two clear numbers with different scopes are more useful than one blended number whose scope nobody can state.
