Collect on your domain
Requests land on a subdomain you own. Browsers treat them as first-party, so tracker blocklists and third-party cookie rules don't touch them.

Server-side tracking
Server-side tracking that catches the conversions your browser pixel misses.

The definition
What is server-side tracking?
In short
Server-side tracking means your conversion events are sent to ad platforms and analytics tools by a server you control, rather than by scripts running in each visitor's browser. Collection happens on a subdomain of your own site, so blockers, Safari's cookie caps and failed pixels stop dictating which results Meta, Google and your CRM ever hear about.
Write it on the server
The event exists as soon as the request arrives. Whether a browser script finished loading no longer matters.
Deliver server to server
Events reach each platform's conversion API with an event ID, so the copy your pixel also sends is dropped automatically.
Keep the identity attached
An anonymous count is of limited use. The click ID stays with the contact until the deal closes, then the result is reported back.
The problem
Your pixel lives in the browser, the place built to block it.
Before a browser pixel can register anything, it has to get past blockers, consent prompts, Apple's privacy features and its own loading quirks. Combined, these can hide up to four in ten conversions.
- ×
Blockers kill the script on load. Many business visitors run one, so for them the pixel simply never fires and their conversions never show up.
- ×
Safari limits cookies to a week. Someone who clicks today and converts ten days later appears as a brand-new, unattributed visitor.
- ×
Consent prompts hold the pixel back. Visitors who decline or ignore the banner are never counted by browser tags.
- ×
iOS opt-outs leave Meta guessing. An iPhone that declined tracking gives the platform nothing to connect back to the ad.
- ×
Third-party calls fail without a trace. Slow scripts, strict security policies, extensions or flaky networks each drop events silently.
- ×
Surviving events arrive thin. With identifiers stripped, match quality drops, so even counted conversions only earn partial credit.
The platform under-reports and optimizes on the subset it saw. A rising CPA is often a measurement issue, not a creative one.

How the data moves
Clicks arrive first-party. Conversions leave server to server.
Browsers talk to your own subdomain, so events are stored before a blocker or cookie limit gets involved. From there they're deduplicated, linked to the CRM contact and returned through each platform's API.

A tracking domain of your own
Collection runs on a subdomain like t.yourbrand.com. Browsers see a request to your own site, which is why blocklists and third-party cookie limits don't apply.
<script src="https://t.yourbrand.com/aa.js" async></script>
Events stored on the server
Each event is saved when the first-party request lands, together with the visitor's consent status, so a failed script never erases a conversion.
Conversions API for each platform
Delivery runs through Meta CAPI, Google Enhanced and offline conversions, LinkedIn CAPI and Microsoft offline conversions. No per-event tag building.

The pixel needs a loaded script plus a surviving cookie. The server layer only needs a first-party request.
- Consent given: full event, deduplicated
- Consent declined: anonymous first-party event

What changes
What improves once conversions are counted server-side.
More conversions visible
Leads, demos and orders the pixel dropped reach the platforms through their APIs, so bidding learns from the full picture.
Higher match quality
Hashed contact details and click IDs on every event raise the match score, and matched events are the ones that get credit.
Lower cost per result
More signal per euro means faster learning and sharper targeting, which is usually where a cheaper lead comes from.
Reports that match the CRM
Ad platform, dashboard and pipeline count the same events, so meetings are about decisions, not reconciling numbers.
No servers to babysit
No container, no cloud invoice, no tag updates queued for engineering. The layer is managed and the subdomain stays yours.
Procurement-ready
EU hosting, first-party collection and a signed DPA answer legal's first questions. Our security page covers the rest.

FAQ
Server-side tracking, common questions
What teams usually ask before moving conversions off the browser.
How is server-side tracking different from server-side tagging?
Server-side tagging usually refers to running a Google Tag Manager container on a server you manage. Server-side tracking is the wider idea of capturing events on a server and forwarding them to platforms. A self-hosted container is one route; a managed layer like Arctic Aura is another, with CRM matching and reporting built in.
Does it work around cookie consent?
No. It improves reliability, not permissions. Arctic Aura collects first-party and stores no personal data until consent is given, so a declined banner stays declined.
Do I need a developer or a GTM server container?
No. You add a DNS record for a subdomain, paste one script and connect accounts via OAuth. There's no container to run or cloud bill to pay. Most teams finish in about 20 minutes.
Will conversions be counted twice alongside my pixel?
No. Browser and server events share an event ID, so the platform keeps one copy. The pixel stays on, and the server fills the gaps.
Why does a first-party subdomain matter?
Blockers rely on lists of known third-party domains, and browsers restrict third-party cookies. A subdomain of your own site avoids both, and identifiers set server-side last months instead of days.
Which platforms receive the events?
Meta via the Conversions API, Google Ads via Enhanced and offline conversions, LinkedIn via its Conversions API and Microsoft Ads via offline conversions. CRM stages can be sent as their own events.
Will it work on my website builder?
Yes. The script sits in the site header, so WordPress, Webflow, Shopify, Wix and custom builds all behave the same, with or without a tag manager.
