CornerstoneServer-side attribution: the post-iOS14 playbook for agencies
Browser tracking is breaking down, and with it your ability to prove the ads worked. This guide walks through first-party measurement, identity resolution, and server-side CAPI to Meta, Google, LinkedIn, and TikTok, the way attribution has to work after iOS 14 and the end of third-party cookies.

- How a first-party pixel keeps the click ID that browser pixels lose.
- How an anonymous click resolves to a named lead and a won deal.
- How server-side conversions get sent back so platforms optimize toward revenue.
Guides
Pillar guides, written to be useful before you ever talk to us.
The long reads. Each one is the honest version of a topic agencies keep getting sold hype about.
Server-side attribution: the post-iOS14 playbook for agencies
What changed, why your dashboards stopped reconciling, and how first-party server-side measurement fixes it.
How to consolidate your agency tool stack without breaking delivery
A practical order of operations for replacing roughly ten disconnected tools with one connected system, one phase at a time.
AVG-compliant tracking: consent-first measurement for Dutch agencies
Deny-by-default consent, IP truncation, and what company-level versus person-level data actually means under the AVG.
Compare
The honest side-by-side.
No straw men. Here is where a stack of point tools or a general agency suite genuinely makes sense, and where one connected system does.
Metiva vs a stack of point tools
Chat, CRM, contracts, invoicing, and a project board that do not share a record. Where the stack wins, and where the reconciliation tax adds up.
Metiva vs a general agency suite
Teamleader, Simplicate, or Gripp bundle the admin, but were built for generic SMBs. What a system configured for Dutch agencies, with the attribution wedge, adds.

Glossary
The vocabulary of server-side attribution, defined plainly.
Every term we use on this site, with a one-line definition and a deeper page. No jargon left unexplained.
- Server-side attribution
- Measuring which ad click produced a sale on your own server, using first-party data tied to a real deal, instead of relying on a browser pixel the platform can no longer reliably see. It is what lets a report reconcile to a client's actual revenue after iOS 14 and the end of third-party cookies.
- First-party pixel
- A tracking snippet served from a domain you control and processed on your own server, so it preserves the ad click ID, UTMs, and referrer that third-party browser pixels increasingly lose to cookie restrictions and ad blockers.
- Server-side tracking
- Recording conversions on your own server rather than in the browser, so they survive cookie loss and blocking. It is the foundation that server-side attribution and CAPI are built on.
- CAPI (Conversions API)
- The server-to-server channel that sends a conversion back to an ad platform with the original click ID, instead of depending on the browser. Metiva has real adapters for Meta CAPI, Google, LinkedIn, and TikTok.
- Click ID
- The identifier an ad platform attaches to a click (fbclid, gclid, ttclid, li_fat_id, and others) that ties a visit back to a specific campaign. Captured at the source by a first-party pixel and preserved for later server-side upload.
- Identity resolution
- Linking a known, consented visit to one canonical person record using hashed identifiers such as email and phone, and folding earlier anonymous click IDs onto that person. It is the bridge that lets a weeks-old anonymous click be attributed to a named lead and a won deal.
- Company-level de-anonymization
- Identifying the company or account behind a visit when person-level consent is not present. Metiva resolves to a named individual only when that person consents through a form capture; person-level tracking is the consented case, not the default.
- Event Match Quality
- Meta's score for how well the data you send with a conversion matches a real person. Higher match quality means the platform can optimize toward the right people. Metiva monitors it hourly.
- Enhanced Conversions
- Google's method of improving conversion accuracy with hashed first-party data. Metiva supports Enhanced Conversions for Leads alongside Offline Conversion Import.
- Consent Mode v2
- Google's framework for adjusting how tags behave based on a visitor's consent choices, deny-by-default in the EU. It pairs with Metiva's consent-first, AVG-aligned tracking posture.
Case studies
Customer stories, when they are real.
We will publish named case studies only once our first Dutch agencies are live and have something specific to say. Until then, the honest proof is the product itself and the founders behind it.
We are onboarding a small group of launch partners now. No fabricated logos, no invented metrics. We would rather show you the system than dress up an empty case-study page.
When a partner is live and has a specific workflow win to talk about, this is where their story will go, with a real screenshot and a named agency.
