Ad spend leak detection
Know when your ads are sending traffic into a broken funnel.
Ads Sentinel scans your ad destinations end-to-end — redirects, tracking, product availability, Add to Cart — and proves what's broken with reproducible evidence, not guesses.
For D2C brands, performance marketers, and agencies who can't afford silent funnel breakage.
The problem
Your ad can be live while the conversion path is broken.
200 OK, broken UI
The server responds fine. The page a visitor actually sees can still fail.
Add to Cart disabled
The button renders. Clicking it does nothing.
Wrong destination
The ad points somewhere other than the landing page you built.
Missing pixel
Meta Pixel, GA4, or Google Ads never fires — spend flows in the dark.
Attribution stripped
UTM and GCLID parameters vanish somewhere in the redirect chain.
Product unavailable
The destination is live. The product it sells is out of stock.
Redirect to homepage
A broken link quietly sends traffic to your homepage instead.
Tracking blocked
A consent layer or script error silently prevents measurement.
How it works
Discover → Scan → Verify → Prove → Alert
Discover
Identify the store, its products, and the destinations paid traffic actually lands on.
Scan
Check the destination the same way a visitor would — HTTP, browser, and interaction.
Verify
Re-check every critical failure independently before calling it real.
Prove
Every verdict ships with evidence: screenshots, redirect chains, network observations.
Alert
Get notified only when something meaningfully changes — not on every scan.
Evidence, not opinions

Every verdict is reproducible. Here is the shape of a real result \u2014 the layout below is illustrative and does not reflect an actual customer scan.

Checks
UTM preservation
All UTM parameters survived the redirect chain unchanged.
Meta Pixel
Unable to verify \u2014 a consent layer prevented a reliable observation.
Add to Cart
The Add to Cart button was visible but disabled.
Who it's for
Built for the people paying for traffic.
D2C founders
Know your ad spend is landing on a funnel that actually converts — without watching every campaign by hand.
Performance marketers
Rule out destination and tracking failures before you start second-guessing creative or bids.
Agencies
Prove to clients, with evidence, that the funnel you're sending spend to is healthy — or exactly why it isn't.
Ecommerce operators
Catch broken Add to Cart, stock, and redirect issues before they quietly burn a day of spend.
FAQ
Questions we get asked
Does Ads Sentinel replace Meta Ads Manager or Google Analytics?+
No. It doesn't measure performance or attribution. It verifies that the destination and conversion path your ads point to actually works.
Do you complete real checkouts or purchases?+
No. We stop at a safe checkout boundary. We never place real orders, enter payment details, or create accounts on your store.
What happens when you can't determine something?+
We say so directly — “unable to verify” — rather than guessing. Every verdict is backed by evidence you can review yourself.
Is my evidence data private?+
Screenshots and scan evidence are stored per organization and only reachable through authenticated routes scoped to your workspace.
Which platforms do you support today?+
Any HTTP(S) destination for redirect, tracking, and attribution checks, with deeper product/catalog checks for Shopify stores today.
Check your first destination.
Create a workspace, add a store, and run a real scan with evidence in a few minutes.
