Why would I hire a specialist just for tracking?

Because every campaign optimizes toward the conversions it is told about. If that signal is wrong, bidding is confidently wrong at scale, so getting measurement right is often the highest-leverage fix on an account.

Is this a full-time role or a project?

Often it starts as a project, the implementation, then becomes ongoing monitoring. Many businesses use an agency or freelancer to build it and only hire in-house when the volume of change justifies it.

How do I test a conversion tracking specialist?

Ask how they would confirm a GCLID survives from click to CRM record, and how they reconcile platform conversions against backend revenue. Both reveal whether they work at the level where tracking actually breaks.

Role

Hire a conversion tracking specialist: agency, freelancer, or in-house?

TL;DR

A conversion tracking specialist is the person who makes sure the numbers every campaign optimizes toward are actually true. Their job is the plumbing: Consent Mode, Enhanced Conversions, server-side tagging, the Conversions API, and offline imports, reconciled against a source of truth. The figures below are illustrative US market ranges.

In-house salary

Illustrative 85K to 150K USD

Agency retainer

Illustrative project or 1.5K to 4K USD/mo

Freelancer

Which hiring option wins?

agency

Pros

Has built the full measurement stack many times and knows the failure modes
Owns server-side infrastructure and CAPI setup rather than leaving it half done
Brings reconciliation discipline against source-of-truth revenue
Can act as a fractional resource, since this is often project work

Cons

May hand off to your team after implementation
Needs access to your systems, which takes coordination
Ongoing monitoring can lapse if scope is only the build

freelancer

Pros

Deep hands-on implementation skill for a defined project
Direct contract without agency margin
Cost-effective for a one-time setup

Cons

Often leaves once the build is done, with no ongoing ownership
Quality varies widely and is hard to verify before hiring
May not stay for the monitoring that catches silent breakage

in-house

Pros

Owns the measurement stack continuously, catching breakage fast
Knows your systems and data flows intimately
Available whenever a site change threatens tracking

Cons

A full-time measurement hire is only justifiable at scale or complexity
The skill set is rare and expensive to retain
One person can become a single point of failure for all measurement

When to upgrade

Most businesses start with an agency or freelancer for the implementation, then decide whether ongoing measurement volume justifies an in-house hire. Bring it in-house when frequent site changes, multiple properties, or complex data flows mean tracking needs constant vigilance. For a single stable site, a periodic agency audit plus a solid initial build is usually enough.
