# I Will Set Up GA4, Google Ads Conversions & Meta CAPI via GTM

If your ad campaigns are underreporting conversions or your analytics data looks patchy since the iOS 14 privacy changes, this service is built to fix that.

Apple’s Intelligent Tracking Prevention and cookie-blocking updates have caused serious blind spots for businesses running Facebook and Google Ads. The result? Your pixel misses conversions, your audiences shrink, and your ad optimisation suffers. This setup closes those gaps by combining browser-side and server-[side tracking](https://zinnhub.com/zinns/fix-or-setup-bigcommerce-server-side-tracking-for-ga4-and-fb-capi/) — so even when a cookie is blocked, your data still gets through.

Using Google Tag Manager, GA4, [Google Ads conversion tracking](https://zinnhub.com/zinns/set-up-google-ads-conversion-tracking-with-gtm-and-enhanced-conversions/), and Meta’s Conversion API (CAPI), your tracking stack is rebuilt to collect first-party data directly from your server, not just the browser. This means more complete event data, better audience signals, more accurate ROAS reporting, and stronger retargeting capability.

\*\*What this setup achieves for your business:\*\*
 – Accurate event tracking that survives cookie restrictions and ad blockers
 – First-party data collection: name, email, phone, postcode, city, county, and country
 – Reliable audience and segment building for retargeting campaigns
 – Better Facebook ad optimisation driven by complete conversion signals
 – Cleaner GA4 reporting with server-confirmed data

\*\*What is included in every tier:\*\*
 – Google Analytics 4 (GA4) events setup — web and server tracking
 – Google Tag Manager container configuration
 – Facebook Pixel installation with Meta Conversion API (CAPI)
 – Social platform tracking integration
 – Tracking goals configured to your specification

The tiers scale by the number of tracking goals and whether e-commerce purchase event tracking is included — so whether you are running a lead generation site, a content business, or a full online shop, there is a scope that fits.

\*\*How it works:\*\*
 Once your order is placed, you will be asked to share your website URL and access credentials for your Google Tag Manager, GA4, Google Ads, and Meta Business accounts. The setup is carried out within the agreed delivery window, and all work is completed directly inside your accounts — nothing is hosted externally.

\*\*Who this is for:\*\*
 Business owners and marketing teams running paid advertising on Facebook/Instagram or Google who need reliable, privacy-compliant tracking. If you are launching a new campaign, scaling your ad spend, or simply tired of inaccurate data, this is the foundation you need.
