Conversion tracking numbers don't add up: dashboard and orders don't match, how do we find what's broken?

If your payment flow redirects to an external bank portal, UTM tags and click ID parameters might be getting dropped on the return URL. Also make sure your cookie banner setup is configured to send pings via advanced consent mode instead of blocking tags outright when consent is denied.

We had the exact same massive gap on our leather bag shop in Florence. Out of 50 orders, only 18 showed up in the ad account. When we dug into it, we realized about 40% of Italian visitors flat out rejected the cookie banner. Once we switched to server-side tracking, our drop-off rate fell from 60% down to around 12%.

Open your browser right now, go incognito, reject the cookie banner, and buy a 1 EUR test product. Watch your tag checker extension when you land on the thank-you page to see if the conversion pixel fires. Dollars to donuts it won't fire at all.

There are four critical points you need to check: 1) A redirect delay when returning from an external payment gateway. 2) The ad platform and store dashboard using different time zones. 3) Failure to pass a transaction ID to deduplicate multiple visits to the thank-you page. 4) The conversion attribution window in the ad platform being set to just a single day.

if you're redirecting to paypal or affiliate pages users pay and then just hit the x and close the tab without clicking 'return to merchant'. most orders get left hanging because of this.

Which payment gateway are you using? Do customers enter their credit card info directly on your site, or are they redirected to an external checkout page? Do all 24 missing orders belong to a specific payment method?

We got into a huge fight with our ad agency last year over this. I kept saying "we spent 1.500 EUR and only got 5 orders," but it turned out we had 30 orders at checkout. Turns out the cookie banner we updated for the Italian Garante regulations wasn't firing any tags before consent was given. Once we fixed the cookie setup, the numbers lined up much better.

I agree, and I'd like to emphasize that. A page that answers one question works better than one touching on five topics.

I'm also curious if anyone does it differently.

If you're going this route, sort this out first. A competitor's ranking might come from years of accumulation, not just their content.

If you post the result here it will help others too.

I was thinking the same thing. A competitor's ranking might come from years of accumulation, not just their content.

When making decisions write down the worst-case scenario too, not just the best. This is my opinion I'm not claiming it's absolute truth.

Exactly like that. The real issue isn't the number, but what it's based on.

Let me summarize the topic, since several different answers were given. Processes without records never improve because you don't know what to fix.

correct.

Three different views emerged, they all complement each other. Don't trust anyone who gives guarantees; there are no guarantees in this business.

Good call starting this thread.

Thanks this was very helpful. If you don't write this down from the start it leads to arguments later.

That's all sorry if I went on too long.

we need to take it step by step and when making decisions write down the worst-case scenario too, not just the best.

taking notes for two weeks yields better results than a six-month estimate. if you post the result here, it will help others too.
