Purchases claimed by the ad account against purchases backed by a paid click in the 90 days before. Counted in the shop backend, refunds deducted.
Up to 40% more conversions* reach your ad accounts — because ad blockers and Safari tracking protection can’t cut off the server route.
* Based on our own client measurements running in parallel with classic pixel setups; results vary by industry, traffic mix and consent rate.

64 % → 0 %
Orders with no origin
EU shop, ~250 orders a day: 48 hours after switching, every purchase had a trail again — clearly attributed orders rose from 26 % to 68 %.
30 % → 12 %
Unattributed orders
UK shop: the checkout stamp rescues purchases whose pixel never fired inside in-app browsers.
485 vs. 480
Claimed vs. sold
Four ad accounts together claimed more purchases than the shop had at all — including every organic one. That is exactly where budget decisions go wrong.
At first we didn’t believe the uncoverflow numbers ourselves, so we checked every single order in the shop. They were right. We plan our budgets off these numbers now, not off what the platforms claim.

Your ad accounts see only part of your sales — and bid on it.
Browsers block pixels, visitors decline cookies, in-app browsers drop the click. Google and Meta then optimise on an incomplete picture — and often credit themselves with sales they never brought.
PROBLEM 01
Browsers block the pixel
Ad blockers, Safari’s tracking protection, Brave and Firefox stop the Google tag and the Meta pixel before they fire. Those purchases never reach Smart Bidding — your CPA looks worse than your marketing really is.
PROBLEM 02
Declined cookies hide real buyers
Everyone who declines the banner drops out of your reporting — including the people who go on to buy. uncoverflow still counts them, cookieless and without accessing their device.
PROBLEM 03
Social sales disguise themselves as “direct”
The in-app browsers of Instagram, TikTok & Snapchat strip the click ID and referrer on the
jump to your shop. Your direct rate explodes and your best social channel looks
dead — so budget moves to the wrong place. Add bridge landing pages and it gets worse.
At a glance
Three layers a pixel doesn't have.
Plenty of tools can do server-side tracking by now. uncoverflow doesn't stop at forwarding:
it measures more, audits the platforms — and turns the truth into decisions.
The order everything here is built in.
LAYER 01 · MEASURE
Capture more, lose nothing
A first-party domain against ad blockers, cookieless measurement without consent, orders via webhook and as a safety net from the shop API. Every event is stored first, then delivered — and re-delivered when a platform API is down.
Click, call, booking, order and paid invoice in one journey — even after express checkout and payment redirects. Refunds are netted against the original conversion, double counts are detected, and a daily scorecard sets the platform numbers against your real revenue.
Return per channel down to contribution margin, budget recommendations with safety limits, audiences from real buyers straight into Google Customer Match, an AI weekly report and data chat — and, with the Copilot, prepared execution you approve with one click.
Every conversion with everything that came before it.
That is not an illustration — it is the page you see after logging in. Every row is one conversion, and underneath, one sentence says why that channel got the credit.
Sample data in the real backend layout. Times, pages and channels are an example — the reading underneath is the one you get.
If any of these sentences sound familiar, you're in the right place.
Online shops
“Orders come in, but in Google Ads I only see 60 % of them.”
The server-side webhook delivers the real order and subscription revenue — and, when
needed, recovers the campaign attribution from the order itself: even for Shop Pay and
express-checkout purchases or multi-domain funnels where classic pixels lose the click
ID. Including
recurring payments (Stripe), SEPA/Klarna, cancellation tracking, a gross/net toggle,
micro-conversions with cart value as a Smart Bidding signal, a correct new-customer share
and Customer Match audiences — across multiple shops and currencies.

Service businesses with lead generation
“Calls and forms bring in the clients — but Google Ads never hears about it.”
Form submissions, phone calls with dynamic tracking numbers, booked appointments and clicks
to external booking services (Shore, Treatwell, Doctolib …) land as real conversions
in your ad account — and the CRM close feeds the
order value back later.

“50 pixels per client — and Google Ads still shows fewer conversions than the CRM.”
One pipeline for all clients, one unified data model, one clean reporting layer.
Plus, per client: a read-only report link (ROAS + calls, no login, PDF-ready)
and, on request, a weekly white-label AI report straight to your client.

Runs alongside your existing tracking. Compare first, then decide.
You don't have to rebuild anything, switch anything off or risk anything: uncoverflow runs
as a second measurement alongside your pixels — and after 30 days the numbers show
in black and white what you've been missing.
Add it — replace nothing
One <script> tag next to your existing pixels —
WordPress, Shopify, Webflow, anywhere. Your running setup, your campaigns and
your Smart Bidding stay completely untouched. After that, a go-live
checklist in the dashboard tells you what is still missing — a tag that isn't
being served, a destination that isn't connected, a looming double count — each with the
link that fixes it.
5 minutes
Measure in parallel for 30 days
At first uncoverflow only collects — in observation mode nothing is sent to the
platforms. Then we compare: what we see, what GA4 and Google Ads
show, what's really in the shop or CRM. At the end you get the result as a finished delta report — in black and white, which conversions you've been missing.
0 risk
Switch over when the numbers convince you
Only now do we connect Google Ads, Meta & co. Our conversion actions
start as secondary actions (observation only) and are only
set to “primary” when you decide. No data chaos, no double counting —
a dedicated check reports if your existing tag and our upload would ever both count as primary.

How you become a customer
From the first call to the first invoice — no surprises.
No form jungle, no contract on trust: six steps, each with a time. You provide access, we set things up, you decide after 30 days.
The path to a running contract. Times are typical values from setups since 2026; the trial is available once per customer.
What you provide
Access to the shop admin — or to the website and the form plugin, plus your phone system for call tracking. Permission for Google Ads and Meta and a sentence about your cookie banner. About ten minutes, once.
What we do
Install the tracker, connect webhooks and pixel, create conversion actions, work through the ready-to-go checklist — and show you where to look.
How long it takes
Adding the snippet: 5 minutes. Setup by us: about 30 minutes per shop. Agencies: one workshop of around 90 minutes, then 20 to 30 minutes per additional client.
No contract on trust: you start in parallel operation and compare our numbers with your
existing setup. 30 days at €0, cancel any time — without cancellation the subscription starts
on day 31, and we remind you 7 days before. All prices net plus VAT.
30-day parallel run included
Full feature set in parallel operation: tracking, dashboard, weekly report, monitoring.
€0 for the 30 test days, no setup fee. You compare and decide —
if it doesn’t convince you, it was a free tracking audit.

Frequently asked questions
The questions everyone asks us first.
Do I still need a cookie banner?
Yes — server-side tracking doesn't change that, and we don't promise otherwise.
The uncoverflow tracker respects your banner: without consent it measures cookieless
and without accessing the device (§ 25 TDDDG) — that data stays in your own
reporting. Only what carries marketing consent goes to Google, Meta & co.
Server-side order and call conversions rest on contract performance or legitimate interest;
we supply the matching wording for your privacy policy (DPA under Art. 28 GDPR included).
Do I have to touch my existing tracking to run a test?
No — in fact that's the recommended path: uncoverflow runs alongside your
existing pixels, at first in observation mode (data is only collected, nothing is sent).
After 30 days we compare our numbers against GA4, Google Ads and your shop/CRM.
When you go live, our conversions get their own, initially secondary
conversion actions in Google Ads — your existing numbers and your
Smart Bidding stay cleanly separated until you deliberately switch over.
What does uncoverflow cost?
Tracking from €299/month, tiered by order volume — the first 30 days of
parallel operation are €0, with no setup fee during the trial. The Copilot starts at
€749/month including tracking. No billing per event, no lock-in,
cancellable monthly. Agencies get partner terms by individual agreement (as a guide 20–30 % below list) and invoice their clients themselves.
Where is the data hosted?
On German servers (netcup, Karlsruhe / Nuremberg). The Postgres database is located exclusively
in Germany, backups are encrypted. A DPA (Art. 28 GDPR data processing agreement) is part of the onboarding package.
Does it work with Shopify too?
Yes. Order and refund webhooks for Shopify are live — clean, deduplicated, with
a gross/net toggle. Every purchase is matched to
Google & Meta instantly via hashed email/phone (Enhanced Conversions & CAPI). For full
journey attribution — which ad drove the purchase — a small
tracker snippet also goes into the Shopify theme; done in about five minutes and described step
by step in the setup wizard.
Multiple shops, countries or currencies?
Yes. Each shop gets its own tenant, click IDs are passed across domain boundaries (say,
from the UK to the EU store, or from an ad landing page into the shop), and ad spend from
foreign-currency accounts is converted to euros at ECB daily rates. ROAS per channel stays
comparable — whatever currency the ad account bills in.
Measure in parallel for 30 days or talk for 30 minutes — your call.
In the trial, uncoverflow runs for 30 days alongside your current tracking on your shop or on one of your clients, with nothing switched off. In the call, we take a live look at one client and compare. No slides, no sales pitch either way.
