Ask a business how their marketing is doing and you’ll usually hear about impressions, likes, or “brand awareness.” Ask which channel produced last month’s best customer and the room goes quiet. That silence is the most expensive sound in marketing.
Attribution is the discipline of answering one question: which pound brought which lead? If you can answer it, marketing becomes an investment with a measurable return — you put more into what works and kill what doesn’t. If you can’t, marketing is a cost centre running on vibes, and the loudest channel (usually the agency with the prettiest report) wins the budget regardless of results.
The mistake is treating measurement as something you look at afterwards. It has to be plumbed in first:
Impressions are how many people walked past your shop. Clicks are how many glanced in the window. Neither pays a salary. When the monthly report leads with reach and engagement, ask for the other numbers: enquiries by channel, cost per enquiry, revenue by channel. If those numbers aren’t in the report, they’re either bad or nobody’s measuring them — and both answers tell you what to do next.
None of this needs an enterprise analytics stack. It needs the tracking wired in before the spending starts, a definition of “conversion” everyone agrees on, and the discipline to read revenue instead of applause. Do that, and every marketing conversation changes from “we feel it’s working” to “this channel returned four to one; this one returned nothing; here’s next month’s plan.”
