# I Will Set Up Google Ads & GA4 Conversion Tracking via GTM

Inaccurate conversion data costs you money. Every mis-fired tag, duplicate event, or untracked purchase means your Google Ads campaigns are optimising against the wrong signals — and your budget is quietly draining away. This service puts a stop to that.

Zinn Digital sets up and fixes Google Ads and GA4 [conversion tracking](https://zinnhub.com/zinns/set-up-conversion-tracking-for-your-google-tag-manager/) using Google Tag Manager, following industry best practices and ensuring your data is as clean, complete, and reliable as possible.

\*\*What’s included across all tiers:\*\*

[Google Ads Conversion](https://zinnhub.com/zinns/setup-google-ads-conversion-tracking-analytics-tag-manager-ga4-gtm/) Tag Setup — covering purchase and sales conversions, lead and contact form submissions, phone call clicks, email link clicks, and button or link tracking. Every tag is configured to fire correctly and record without duplication.

GA4 Enhanced eCommerce Tracking — the full standard eCommerce event suite: view\_item\_list, select\_item, view\_item, add\_to\_cart, remove\_from\_cart, view\_cart, begin\_checkout, and purchase. Revenue data flows accurately into both GA4 and Google Ads.

Server-Side Tracking (available in higher tiers) — the most accurate data collection method currently available. Tags fire from your own first-party domain, making them resistant to ad blockers and Intelligent Tracking Prevention (ITP) browsers. This is the only reliable solution when third-party cookies are blocked, ensuring your reported figures are consistent across platforms.

\*\*Common problems resolved:\*\*

— eCommerce revenue not appearing in Google Ads or GA4
 — Conversion tags failing to fire or record correctly
 — Duplicate tag firing causing inflated or unreliable data
 — Tracking goals not configured or misconfigured in the account

\*\*How it works:\*\*
