Ad platforms are happy to tell you about clicks and cost per lead. What they can’t tell you — and what actually matters — is which of those leads turned into revenue six weeks later.
Without that link, budget decisions get made on the metrics that are easy to see. The channel producing lots of cheap, unqualified leads looks like the winner over the one producing a handful that all close.
Closing the loop means connecting three things that usually live apart: the ad and campaign data, the lead capture, and the CRM outcome.
- Source capture at the point of entry — UTM parameters, referrer and campaign stored on the record itself, not just in a session.
- Consistent naming across channels, so campaigns can actually be compared. Unglamorous, and the thing that most often breaks the whole exercise.
- Persistence through the pipeline, so the original source survives a stage change and a record merge.
- Offline conversion feedback into Google Ads and Meta, so the platforms optimise toward revenue instead of form fills.
- Reporting that shows cost per qualified lead, cost per acquisition and return by channel, campaign and audience.
We’ll also be straight about the limits. Multi-touch attribution over a long sales cycle is directionally useful, not precise, and anyone promising exact numbers is selling something. The goal is to be confident enough about the big differences to move money.
