PROBLEM · SOLVED BY AI & INTELLIGENCE · AUTOMATION & CRM · PAID ADVERTISING

No attribution loop. You're not flying blind — you're flying with someone else's instruments.

When you can't see what's working, the platforms decide for you. We close the loop with server-side events and CRM-back signal — properly.

Symptoms

If any of these sound familiar, this is your problem.

01

Three platforms each claim the same conversion

02

You've paused things that "didn't work" and revenue dropped

03

Last-click in GA4 disagrees with sales-team gut

04

Nobody can answer "which channel drove last month's £200k"

Why it happens

The root cause — in plain English.

Browser cookies were the spine of attribution and they've been quietly amputated since iOS 14, ITP, and consent mode v2. Most accounts still measure with 2019 plumbing — client-side tags, last-click models, no offline conversion uploads — and call the result "performance data". The platforms then show you what they want you to see, and you redirect budget on hallucinated data. Closed-loop attribution isn't optional anymore; it's the price of entry.
How we diagnose it

The first three things we check.

We rebuild attribution in three layers. Layer one: server-side tagging via GTM server container, so events fire from your domain not the user's browser. Layer two: send the CRM's won-deal events back to Google and Meta as offline conversions, so the algorithms train on real revenue not form fills. Layer three: a single source of truth dashboard that reconciles platform-reported numbers with CRM-reported numbers. Two weeks, three steps, no guesswork.
The cost of waiting

Without a closed loop, the platforms optimise toward the cheapest event they can find — usually a junk lead. You'll spend a year scaling spend on phantom performance before the cash flow tells you the truth.

First action this week: Run a single test: take last month's top "winning" campaign in Google Ads and ask sales how many of those leads became revenue. If they can't answer, you don't have attribution.
