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

Stop making business decisions on incomplete or broken data. When your Google Analytics 4 and Google Ads conversion tracking are configured correctly, you gain a clear picture of exactly how customers behave on your site, which campaigns are driving real revenue, and where your ad spend is working hardest.

Zinn Digital, based in London, England, has over five years of dedicated tracking and web analytics experience. Every setup is built for accuracy, so your GA4 reports and Google Ads bidding algorithms receive the reliable signals they need to perform.

\*\*What this service covers:\*\*

All tiers are delivered through Google Tag Manager (GTM) and cover the full installation process — from creating accounts if you do not yet have them, right through to verifying that data is flowing correctly.

The Entry tier establishes your GA4 foundation: GTM installation, Page View tracking, Google Signals activation, Enhanced Measurement configuration, and Data Retention settings — everything you need to start collecting meaningful audience data immediately.

The Standard tier adds eCommerce purchase tracking with dynamic order value, so you can see exactly which keywords, ad groups, and campaigns are generating revenue. One Google Ads conversion action is also configured, enabling smarter automated bidding.

The Full tier delivers the complete tracking stack: all Standard features plus up to ten tracking goals, social platform tracking, cross-domain tracking, a remarketing tag for Google Ads, and the full GA4 eCommerce dataLayer (View Item, Add to Cart, View Cart, Checkout, Remove from Cart, Purchase, Lead Form, Button Click, and more).

\*\*Platforms supported:\*\*
 Shopify, WordPress, Wix, BigCommerce, Magento, Laravel, and any custom site or CMS.

\*\*How it works:\*\*
 Once you place your order, share the required access details (GTM admin, GA4 editor, and website backend access). Work begins promptly, and post-delivery support is available via order chat if any questions arise after completion.

\*\*Who this is for:\*\*
 eBusiness owners wanting to understand customer behaviour, marketing managers needing reliable conversion data for Google Ads optimisation, and developers or agencies requiring a clean, professional tracking implementation for a client site.

If your specific requirements do not fit a standard tier, send a message before ordering and a custom package can be arranged.
