Website Privacy Banner Implementation & Google Tag Manager Cleanup (Custom/Non-WordPress Site)

We are looking for a Google Tag Manager (GTM) and Web Analytics specialist to update privacy compliance and clean up the tracking architecture on a website built on a non WordPress, custom platform. Our goal is to ensure no nonessential analytics scripts fire automatically on initial page load before a user interacts with the site. Since the site is on a custom framework, the entire solution must be managed seamlessly through Google Tag Manager. KEY RESPONSIBILITIES: 1. Clean Up Background Tracking Codes: Audit the website's active tags inside Google Tag Manager. Identify and remove any old, duplicate, or dormant tracking codes that are no longer needed. 2. Set Up a Free Privacy Consent Banner via GTM: Deploy a completely free tier or open source cookie consent banner injected directly via Google Tag Manager (ensuring zero ongoing monthly software fees for the client). 3. Configure Script Gating: Update the container triggers so that Google Analytics 4 (GA4) and other tracking elements are properly gated. They must only execute after a user interacts with or accepts the banner. 4. Update the Privacy Page: Provide the standard, compliant text layout for the privacy page that accurately reflects the new cookie and consent setup so we can update the site's privacy page. PROJECT TYPE: One time project BUDGET: Fixed Price ($150)
