Plenty of tools tell you a pixel is "installed". That's the easy part - a plugin can do it. duckmetric opens your site in a real browser and watches the network: what each platform sends, when it sends it, and whether the data inside is correct.
The free scan runs in seconds. Here's what happens behind it.
Not a source-code grep. We render the page like a visitor's browser would, so tags injected by GTM, consent managers or your CMS all load the way they really do in production.
GA4, Google Ads, Meta, TikTok, Pinterest, Snapchat, Bing, LinkedIn - we capture the calls each one makes. A script can be on the page yet never fire an event. We show you which is which.
A purchase without value, currency or transaction_id is broken even if it "fires". We check parameters, duplicates, consent timing and server-side dedup (CAPI event_id).
A clear report with a score, issues ranked by severity, business impact and technical recommendations you can hand to a developer, agency or internal team.
We'd rather be honest about the limits than pretend a free crawl sees everything.
Page views, product views, category/list views, search, consent timing, config quality and presence across every platform - the surface and the start of the funnel.
Add-to-cart and begin-checkout by simulating clicks - best-effort, because every shop's buttons differ.
Purchase and add-payment-info need a real transaction or a connected ad/analytics account. That's the full audit.
