Extend Attribution Beyond 7 Days
Longer sales cycles — enterprise deals, considered purchases, multi-session journeys — stay attributable.
FIRST-PARTY DOMAIN TRACKING
Set server-side cookies from your own domain. Keep every shopper and lead identified.
Browser cookies expire in 7 days. Click IDs disappear. Returning visitors look like strangers. Server-side cookies from your domain fix that.
CNAME setup on your domain. Cookies set server-side. Identity persists across sessions. EMQ and attribution improve.
WITHOUT THIS
Your cookies expire in 7 days. Your attribution breaks with them.
Safari and Firefox cap third-party and client-side cookies at 7 days. A shopper who clicks your ad Monday and buys Saturday is already a stranger.
01
Click IDs disappear
fbclid and gclid are stored in cookies. After 7 days, they're gone. The conversion can't match the click.
02
Returning visitors reset to anonymous
A customer visits three times before buying. Each visit looks like a new person. Your retargeting audience is inflated with duplicates.
03
EMQ drops without identity context
Thin cookies mean thin identity. Meta can't match events to users. EMQ stays at 3-4.
Why CustomerLabs wins here
CustomerLabs sets cookies server-side from your own domain, so identity persists beyond browser ITP limits. Most CAPI tools send events server-side but still rely on client-side cookies that expire in 7 days.
HOW IT CONNECTS
Your domain → CNAME → server-side cookies → persistent identity
1PD Ops tracks ALL purchases (online & offline) across systems and builds custom events for analysis. It even generates attribution reports for offline purchases, helping optimize marketing spend. 1PD Ops have zero limitations in tracking or customizations. Life made easy!
HOW IT WORKS
Add a CNAME record. Cookies set from your domain automatically.
One DNS change. No code. Identity persists from day one.
Add CNAME
Point a subdomain (e.g. cl.yourdomain.com) to CustomerLabs. One DNS record.
Verify
CustomerLabs confirms the CNAME is active. Takes minutes.
Cookies activate
Server-side cookies are set from your domain on every visit. Lifetime extends to 1 year.
Identity persists
Click IDs, browser IDs, and user identity survive across sessions. EMQ and attribution improve.
COOKIE PERSISTENCE
Identity survives beyond browser limits
Server-side cookies from your domain last up to 1 year.
Bypass ITP 7-day cap
Safari and Firefox cap client-side cookies at 7 days. Server-side cookies from a first-party domain are not affected.
Click IDs stay alive
fbclid and gclid persist on the cookie. When the purchase happens days later, the click ID is still there.
Returning visitors stay identified
A shopper who visits three times is one person, not three anonymous sessions.
SIGNAL TRUST
Events arrive from your domain, not a third-party
Ad platforms trust first-party signals more.
Higher domain trust score
Meta and Google give more weight to events from your own domain. Third-party domains are deprioritized.
Better EMQ from stronger identity
Persistent cookies mean richer identity on every event. More identifiers = higher match confidence.
Attribution stays connected
The ad click, the return visit, and the purchase all share the same identity. No broken attribution windows.
WHAT THIS UNLOCKS
With first-party domain tracking, you can:
Persistent identity changes what your campaigns can measure.
Improve Event Match Quality
Dundas Life did it. Persistent cookies + full identity + server-side delivery.
See Conversions API
Reduce Duplicate Profiles In Audiences
One cookie = one person. Retargeting pools shrink to real unique users.

FAQ
Common questions about first-party domain tracking
Direct answers first.
What is first-party domain tracking?
Setting cookies from your own domain (via CNAME) instead of a third-party domain. Server-side cookies bypass browser ITP limits that cap client-side cookies at 7 days.
How does the CNAME setup work?
Add one DNS record pointing a subdomain (e.g. cl.yourdomain.com) to CustomerLabs. That's it. No code changes.
Does this bypass ITP?
Yes. Safari's ITP caps client-side cookies at 7 days. Server-side cookies from a first-party CNAME domain are not subject to this limit.
How does this improve EMQ?
Persistent cookies mean richer identity on every event. More identifiers per event = higher match confidence on Meta.
Do I need this if I already use Meta CAPI?
Yes. CAPI sends events server-side, but if your cookies expire in 7 days, the identity on those events is still thin. 1P domain tracking fixes the cookie side.
Does this work with Shopify, WooCommerce, and other platforms?
Yes. The CNAME is a DNS-level change. It works regardless of your ecommerce or website platform.
