Fix a conversion tracking problem
Problem-led diagnostics for specific failures. Each one starts from the symptom you can see, names the mechanism underneath it, and gives the diagnostic order that rules out a class of cause at each step — so by the last one there's usually a single explanation standing.
Search for your symptom rather than your suspicion. The cause is often not where people expect it.
Do I need server-side tracking
Do I need server-side tracking?
Server-side tracking is oversold. The specific conditions where it pays for itself, the ones where it doesn't, and how to measure your own case before spending.
booked calls to closed revenue
How do I track booked calls through to closed revenue?
Connect the ad click to the booking, the booking to the meeting held, and the meeting to the signed deal — with cancellations reversed.
Tracking qualified leads not form fills
How do I track qualified leads instead of form fills?
Optimising on form fills buys you junk leads. How to capture the click ID, send qualification back, and pick the stage that has enough volume to train bidding.
How much data am I losing

Nobody can tell you a percentage without looking at your account. The reconciliation that produces your real number, and what each component of the gap means.
ad blocker signal loss
How much conversion data are ad blockers costing me?
Blocked pixels don't error or warn. How to measure what your blocked traffic actually costs, and what first-party server-side recovers.

Should I import GA4 conversions into Google Ads?
Usually not, if you already track natively. Why importing duplicates, when it genuinely helps, and how to decide.
consent modelling misunderstood
What is consent modelling actually doing to my numbers?
Modelled conversions aren't fake and aren't observed. What modelling estimates, when it works, and why decimals appear in your reports.
Which conversion number to trust
Which conversion number should I trust?
Four systems, four numbers, none matching. Which one answers which question, why they can't agree, and how to pick a source of truth that settles the argument.
iOS attribution loss
Why am I losing attribution on iOS?
ATT and Safari's ITP are two separate changes that break different things. How to tell which is costing you, and what actually recovers it.
Google Ads cross-domain conversion loss
Why am I losing Google Ads conversions across domains?
Conversions lost when the journey crosses domains. gclid persistence, linker parameters and the redirects that strip both.
gbraid and wbraid missing
Why are gbraid and wbraid missing from my iOS traffic?
iOS app traffic uses gbraid and wbraid instead of gclid. Capturing only gclid loses a growing share of mobile attribution.
consent defaults missing
Why are my consent defaults missing?
No default state declared means Google never knows what the visitor chose before the banner loads. Why modelling fails and tags leak.
GA4 conversions counted incorrectly
Why are my GA4 conversions counted incorrectly?
Key event counts that don't match reality. Once-per-session vs once-per-event, duplicate firing and events marked as conversions by mistake.
GA4 ecommerce parameters missing
Why are my GA4 ecommerce parameters missing?
Events recording without currency, value or items. Why GA4 discards the payload silently and how to send it correctly.

The CRM has the lead and the ad platform doesn't. Blocked events, consent, deduplication and the click ID that was never captured.
Meta server events missing user data
Why are my Meta server events missing user data?
CAPI events arriving with no customer parameters. Where the data gets dropped, hashing errors, and why match quality stays low.
Platforms over-attributing revenue

Why are my platform reports under-attributing revenue?
Platforms reporting less than they earned. Which part is correct attribution and which part is a recoverable measurement loss.

Why are my purchases not showing in GA4?
Purchase events missing from GA4. Malformed items arrays, filtered internal traffic, consent blocking and reporting delays — how to tell which one you have.
Tags firing before consent
Why are my tags firing before consent is given?
Tags sending data before the visitor chooses. Load-order faults, hardcoded scripts outside the container, and how to prove nothing leaks.

server GTM not reaching GA4
Why aren't my server GTM requests reaching GA4?
Events arriving at the server container and never appearing in GA4. Client claiming, tag configuration, measurement ID and consent.
SPA route changes not tracked
Why aren't my single-page app route changes being tracked?
React, Next.js, Vue and Framer sites recording one page view per session. Why history-based navigation needs explicit tracking, and how to wire it.
call-to-sale attribution missing
Why can't I attribute sales back to the calls that produced them?
Calls become customers and nobody can trace it. The three links in the chain and where each one breaks.

Why does changing my attribution window change my results?
The same period reporting different numbers under different windows. What a window actually does, and how to pick one and stop moving it.

Both paths sending valid IDs that don't match, so nothing deduplicates. Where the second ID comes from and how to make one authoritative.
