Proven know-how
From Samsung to Hyundai Motor, the problems we kept running into across these brands' GA4 and Tag Manager setups are exactly what the diagnosis now checks for.
How GA4 is actually collecting, gathered into one diagnosis.
Thirty items across six areas — event collection, conversions, parameters, property settings, tagging, and integrations — read straight from the GA4 Admin and Data APIs. It catches duplicate event pairs, conversions never marked as key events, and purchases arriving without value or currency.
Every check lands on pass, warn, or fail, weighted into one total. A single critical failure — the kind that throws off revenue entirely — caps the grade at C no matter how good the rest looks. Each verdict shows the numbers behind it.
The detailed report says what is wrong on each item, which metric it distorts if left alone, and exactly which GA4 menu to fix it in. Early orders also come with a human-reviewed priority plan.

What it found
FailCV-02Conversions not collecting
A conversion that is registered but never collected reads as zero. You end up switching off a campaign that was selling perfectly well.
FailPR-02Parameter missing rate
When a field often arrives empty, every breakdown built on it is distorted. "(not set)" takes the top row and you cannot tell which segment is actually performing.
FailCV-03Conversion value collection
Without the purchase amount, you cannot judge performance by revenue. ROAS and revenue-by-campaign cannot be calculated at all, so budget gets split on conversion counts alone.
The detailed report takes every item through what went wrong, what you can no longer see because of it, and how to fix it — down to the GA4 menu path.
