Move your conversions off the browser and onto infrastructure you own
Server-side tracking doesn't remove the browser — it moves the decision about what leaves your site out of a browser that iOS, ad blockers and consent banners are all working against, and onto a first-party container on your own subdomain. Your money events get sent from your order records instead, so the conversion arrives whether or not the customer's browser cooperated. We reconcile it against your own orders and put 95%+ accuracy in writing.

Server-side tracking · what breaks
What this is actually for — Server-side tracking
- 01
Reported conversions well below your order count
The gap that server-side is built to close — though it should be measured before it's assumed.
- 02
Safari and iOS a large share of your traffic
Where the seven-day cookie cap does the most damage.
- 03
Attribution collapsing on longer consideration cycles
Anyone who takes more than a week to buy returns as a stranger.
- 04
Purchases lost when checkout redirects
Wallets and hosted payment pages that can be abandoned after the money moves.
Server-side tracking · the fix
What you get out of it — Server-side tracking
Money events sourced from the order record
So they arrive regardless of what the browser did.
First-party cookies with a real lifetime
Set in an HTTP response, so not subject to the cap that applies to JavaScript-set cookies.
Consent enforced at the container
A denied destination receives nothing, rather than being trusted to ignore a flag.
Match quality that supports delivery
Hashed customer identity attached server-side, where the browser had none.
Server-side tracking · architecture
Why the numbers were wrong before you got here — Server-side tracking
Worth understanding before buying anything, because it decides which tier you need — and for some readers the answer is that you don't need us yet.
- 1
The browser is the weakest link, and it is getting weaker on purpose
Every browser-side tag has to survive the page loading, the visitor staying, the script running and the request leaving. All four are now contested. The order in your database is certain; the browser event reporting it is not.
- 2
Safari caps the cookie your attribution depends on
Intelligent Tracking Prevention limits JavaScript-set cookies to seven days whatever expiry you set, so a customer who takes longer than a week to decide returns as a stranger. A cookie your own server writes in an HTTP response is not capped — the single largest practical difference between browser-side and first-party server-side.
- 3
Ad blockers remove the tag with no error
A blocked pixel does not warn anyone. The customer buys, the order lands, and no platform hears about it. First-party events from your own subdomain are not a third-party request and are not filtered the same way.
- 4
Consent is enforced by hope, not by architecture
Client-side consent means trusting each vendor script to honour a flag. A server container decides at the container: a denied destination receives nothing. That is a materially stronger position, and it also stops the over-blocking that discards data no law required losing.
- 5
Checkout can end where your tag isn't
Wallets and hosted payment pages can be abandoned after the money moves. Sending the purchase from the order record means it arrives whether or not anyone came back.
Server-side tracking · diagnose
How we scope the server-side build
Before quoting. Each step narrows what the work actually is, so the price reflects your account rather than an average.
- 01
Measure the real gap first
Reconcile before deciding. A small gap means this isn't your problem.
- 02
Segment by browser
Safari versus Chrome tells you how much of the gap ITP actually explains.
- 03
Check the browser events are even correct
Moving a broken event to a server produces a broken server event.
- 04
Inventory every existing firing path
All of them keep running after the container goes live unless removed.
- 05
Confirm backend order data is reachable
A webhook or API. Without it, a server container is only a proxy.
- 06
Decide hosting before building
Cost, data residency and who holds the keys — easier before the tags exist than after.

Source of truth
Your backend order records, segmented by browser
- The tagging subdomain resolving on your own certificate, with no mixed-content warnings.
- First-party cookies set in an HTTP response, confirmed persisting past seven days in Safari on a real device.
- Purchase events within a few percent of backend orders for a closed week, matched on order ID.
- Deduplication confirmed at every destination that supports it.
- Consent verified by denying it and confirming nothing leaves the container.
- Reconciled over a fully closed window, matched on ID rather than on totals — totals hide equal and opposite errors.
- Payload evidence captured from real transactions, saved to your own records.
- The same reconciliation repeated 30 days later, because a setup that works once and drifts is the harder failure.

Server-side tracking · when not to buy
When you shouldn't buy this — Server-side tracking
We would rather say it now than three weeks into an engagement.
- You spend under roughly $5,000 a month across all paid channels. Hosting and build will outrun the recovered signal.
- Your client-side tracking has never been audited. Fix and verify that first — a meaningful share of accounts need nothing more.
- Almost none of your traffic is Safari or iOS. The main mechanism this defeats barely applies to you.
- You have no backend order source a container can read. Without it you get a proxy, not a source of truth.
- Nobody on your side will own it. A server container is infrastructure and needs someone who notices when it breaks.

Pricing
Pick the package that fits your ad spend
Browser-side starter
$400One-time fee · lifetime ownership
The correct browser-side build, done properly and verified on a live transaction. Honest about its ceiling: it will not survive Safari's cookie cap, an ad blocker, or a checkout that ends somewhere your tag isn't. If you spend $1K+/month on paid media, start one tier up.
- Correct events, correct parameters, correct values
- Verified on a live transaction, not in preview
- Reconciled against your own order records
- Written handover you keep
1st-party server-side
Recommended$800One-time fee · most popular
The tier that changes the outcome rather than patching it. Your money events stop depending on the browser: they are sent from your order records through a first-party server container on your own subdomain, so iOS, ad blockers, consent banners and interrupted payment redirects can no longer take them away. Built in 2–4 days. You own the stack outright, with no monthly SaaS.
- First-party server container on your own subdomain
- Money events sent from your order records, not the browser
- Meta, Google, TikTok, Microsoft and LinkedIn all fed server-side
- Deduplicated on a shared event ID, verified at every destination
- First-party cookies beyond Safari's 7-day cap on JavaScript-set cookies
- 95%+ conversion accuracy and 8+ Meta EMQ, guaranteed in writing
Full 1st-party stack
$1,800One-time fee · lifetime ownership
Every paid-media channel server-side, plus the offline loop that connects closed revenue back to the click. For advertisers whose spend makes an attribution leak more expensive than the build.
- Everything in 1st-party server-side
- Pinterest, Snapchat, Reddit and LinkedIn CAPI
- CRM and offline conversion loop, so closed revenue reaches bidding
- Refunds and cancellations reversed at every destination
- Klaviyo identity stitching, BigQuery and Looker Studio
- Monitoring, so the next break surfaces in days rather than a quarter
FAQ
Server-side tracking questions, answered
No, and anything sold that way should worry you. It enforces consent decisions more reliably than client-side gating, but it does not reduce your obligations.
No. It recovers the part lost to cookie caps, blockers and interrupted redirects. Consent-denied users and genuinely unattributable orders stay unattributable, and should.
Hosting is a recurring cost whether that's Cloud Run, a managed provider or self-hosted. That recurring cost is exactly why the spend threshold exists.
For setup, usually not. For ownership, yes — something will eventually break and someone needs to be able to look at it.
Backend orders against platform-reported conversions over a fully closed window, matched on order ID. You can run it yourself, which is the point.
