SnapchatWhen someone visits your site, clicks "add to cart" or buys, a message should travel to your tools - Google Analytics, Google Ads, Meta - saying "here's what happened." Those messages build your reports, and the ad platforms use them to learn who to show your ads to.
The problem: those messages are often sent with errors, or not sent at all - and it doesn't show. The ads keep running, the money keeps going out, but the signal they're supposed to optimise on isn't there. duckmetric shows you exactly which messages arrive correctly and which quietly go missing.
duckmetric reads your site the way the ad platforms read it - then tells you, in plain language, where the money leaks.
A real browser opens your pages and watches what each platform actually fires - not just whether a tag exists.
The whole journey to purchase, server-side tracking and whether the right purchase values are sent - the part a free check can't reach.
Every event × every platform in one matrix. Spot the gap where you pay for ads but the signal never arrives.
Catch tags firing before consent and broken Consent Mode v2 - real liability in the EU.
Know the same day an update breaks your tags - alerts via email, Slack or Teams.
Confirm your funnel fires for real visitors in production, not just in a test scan.
A clear tracking health report: which platforms fire, which events are missing, what duplicates, where consent is broken, and what to fix first. Written so a founder, marketer, agency and developer can all act on it.
Here's what the expensive gap we most often find looks like.
A store spends €3,000/month on Meta ads. The Meta Pixel is installed, PageView fires - everything looks fine.
But the Purchase event never reaches Meta.
So Meta sees zero conversions, optimises the ads blind, and the ROAS in your reports is fiction. Months of budget spent on data that isn't there. duckmetric flags that one empty cell in seconds.
