# I Will Fix and Set Up Conversion Tracking via GTM, GA4 and Meta Pixel

Wasted ad spend almost always traces back to one root cause: broken or incomplete conversion tracking. If your tags are firing incorrectly, your GA4 events are missing, your [Meta Pixel](https://zinnhub.com/zinns/fix-or-setup-meta-pixel-fb-conversion-api-ipv6-update-server-side-tracking/) is deduplicating poorly, or your Google Ads conversions simply say ‘Needs Attention’ — your campaigns are flying blind. This service fixes that.

With over three years of hands-on experience and 85+ successful tracking projects, Zinn Digital delivers expert setup, repair and optimisation of your entire tracking stack through Google Tag Manager (GTM). Every tier is built around giving you clean, consistent, trustworthy data across your advertising and analytics platforms.

\*\*What this service covers:\*\*
 Depending on the tier you choose, your setup can include any combination of the following — all implemented cleanly through GTM:

• Google Tag Manager installation and container configuration
 • Google Analytics 4 (GA4) setup, including cross-domain tracking
 • GA4 eCommerce purchase tracking (view item, add to cart, purchase)
 • Google Ads conversion tracking and Enhanced Conversions
 • Offline conversion tracking and GCLID tracking
 • Meta (Facebook) Pixel setup with event tracking
 • Facebook Conversions API (CAPI) for server-side accuracy
 • LinkedIn Conversion tracking
 • Form tracking — including AJAX, iFrame, multi-step and dynamic forms
 • Appointment and Calendly booking tracking
 • Vimeo and YouTube video engagement tracking
 • Google Consent Mode v2 implementation
 • DataLayer configuration
 • Google Sheets offline tracking (free CRM integration)
 • HubSpot and Zapier integrations
 • Shopify tracking setup

\*\*Common issues resolved:\*\*
 • Tag fired failed / Tag Inactive / Needs Attention errors
 • Event deduplication between browser and server
 • Event Match Quality improvements
 • Conversion data mismatches between Google Ads, GA4 and Meta

\*\*How it works:\*\*
 1. You share your website URL, GTM/GA4/Ads account access and any specific tracking goals
 2. Zinn Digital audits your current setup and implements the agreed tracking configuration
 3. All tags are tested and verified before handover
 4. You receive your completed, working tracking setup — ready to power profitable campaigns

\*\*Who this is for:\*\*
 E-commerce store owners, digital marketing managers, media buyers, agencies and growth-focused businesses who need their conversion data to be accurate, consistent and scalable.
