Your e-shop is measuring wrong: 5 signs your analytics are losing sales

We audit the analytics of every e-shop we take on. In most we find the same issue: GA4 shows fewer sales than actually happened. That's not a rounding error — it's lost signal that taxes every advertising euro. Here are the five most common signs.

1. GA4 shows 20-40% fewer orders than your back office

Compare a month of orders in your store admin with purchases in GA4. Up to ~10% gap is normal (ad blockers, consent). 20-40% means broken tracking — usually purchases lost on redirect payments (card, PayPal) where the customer never returns to the thank-you page.

2. Google Ads shows zero conversions while you have sales

Classic and sneaky: GA4 records purchases but Google Ads shows 0 conversions. Usual cause: a broken GA4 → Ads import, or purchases recorded without the click ID (gclid). Result: Smart Bidding optimizes blind and your cost per sale climbs.

3. Sales show up as Direct / Unassigned

If your biggest sales channel in GA4 is "Direct" or "Unassigned", the system doesn't know where customers came from. You pay Google and Meta but the credit goes… nowhere.

4. GA4 revenue never matches reality

Duplicate purchases from two sources, wrong currencies, values sent without VAT or shipping. If the numbers don't reconcile with accounting, no report can be trusted.

5. Nobody ever re-checked the tracking after setup

Tracking breaks silently: a theme update, a new checkout plugin, a consent banner change — and events stop. Without systematic monitoring you find out months later, after it has already cost you.

What we do differently

On the e-shops we manage we run a double net: client-side measurement for correct campaign attribution, plus server-side capture so no order is ever lost — even if the site breaks. On top, automated alarms fire when a campaign spends without recording conversions. Suspect your e-shop measures wrong? Ask us for a free audit — we'll show you exactly what's leaking and where.
