The same conversion, wired once per platform, counted once per customer.

Each ad platform needs its own conversion tag. We configure those tags in GTM against the approved event, apply the required consent behavior, and check for duplicate firing. You end up with browser-side conversion tags that fire once under the required consent state, with platform-side evidence of receipt.

We use the approved conversion event consistently across every platform that needs it. We confirm the conversion list, configure tags, verify platform receipt, and test consent and duplicate scenarios.

How we hold ourselves to it

Map conversions to each platform's tag — We take your already-approved conversions and build the matching tag for Google Ads, Meta Pixel, LinkedIn Insight Tag, or whatever platforms you run.
Firing tags on the exact conversion moment — We fire each tag on the exact event that represents the conversion. An approximate page load can misfire, so we don't rely on it as a stand-in.
Does every platform respect the same consent signal? — We make sure each tag respects the same consent signal, since ad platforms and GA4 can otherwise end up with different rules for the same visitor.
Prevent double-counting — Where a value can be sent by more than one tag or platform, we add the checks needed so your reports don't inflate the number.

Confirm the conversion list
We start from conversions already defined in GA4 or your business systems. This isn't a new definition exercise. A person confirms no new conversion gets defined here.
Conversion list
Build the platform tags
We configure each ad platform's conversion tag in GTM with the correct trigger and value parameters. We configure the actual trigger and value parameters.
Tag configuration
Test with real and simulated conversions
We run test conversions through each platform's own verification tools to confirm they're received correctly. A person confirms the platform's tool shows it received.
Platform verification log
Check for duplicates and consent gaps
We confirm no conversion fires twice and that declined consent is respected consistently across platforms. We test declined consent on every wired platform tag.
Deduplication and consent report

One conversion, wired the same way to every platform that needs it

Automation pulls the agreed conversion list, maps each one onto the matching platform fields, runs a test conversion through every platform's own checker, and flags where the same value could fire twice. People hold the gates: no new conversion gets defined during implementation, and someone reads the platform's receipt rather than trusting GTM Preview.

Each tag is documented and verified with the destination platform's own diagnostic tools.

What to check the next time a new ad platform or conversion gets added.

We call it done when: each platform's own diagnostic tool shows the conversion arriving once, and a declined-consent run produces no request.

Already-approved conversions that just need wiring to ad platforms are the clearest sign this is the right task.

A good fit when

Your conversions are already defined and agreed, and now need to be connected to Google Ads, Meta, LinkedIn, or another platform's tags.
You're adding a new ad platform and need its conversion tracking built to match what you already have.
You suspect the same conversion fires more than once on some platforms, while other platforms receive nothing at all.

Better handled as other work when

You have not decided what counts as a conversion yet. GA4 Event & Conversion Tracking owns that definition inside GA4.
The problem lies in how GA4 measures the conversion rather than in the ad-platform tags. That also belongs to GA4 Event & Conversion Tracking.

If one of these is closer to your situation, start here instead: All Google Tag Manager Consulting tasks

We call it done when: the conversion list is closed and agreed, so implementation wires what already exists instead of inventing new definitions along the way.

Zeo designs measurement systems that connect a business decision to governed collection and reporting you can check. The people shown here work on the part of that system this page covers.

Plan conversion tags

Which platforms can you wire up?

Google Ads, Meta, LinkedIn, and most platforms that support a browser-side or GTM-compatible conversion tag. Tell us your ad mix and we'll confirm the specifics.

Will this conflict with GA4's own conversion tracking?

No. GA4 still owns which events count as conversions, and this task takes that already-approved list and connects it to your ad platforms. If the definition itself is still in question, GA4 Event & Conversion Tracking is the task that settles it. Once GA4's side is settled, we build the matching tag for each platform without redefining the event underneath it.

How do you know a platform actually received the conversion instead of just seeing that GTM fired the tag?

We check the platform's own diagnostic tools instead of stopping at GTM's Preview mode. A tag firing in GTM doesn't guarantee the destination processed it correctly.

Which ad platform access do you need?

Access to your ad platform accounts (or someone who can grant tag permissions there), plus your confirmed conversion list from GA4 or your business systems.
