Google Tag Manager Expert Services
Google Tag Manager Installation
Container code installed correctly across every page of your site.
Correct GTM container code installation across your website — head and body snippets placed precisely for reliable tag firing on every page.
Our GTM installation service covers platform-specific implementation for WordPress (via code injection or a managed plugin), Shopify (theme liquid file editing), Webflow (project settings code injection), Wix (tag manager app or custom code), React and Next.js (router-aware implementation to handle SPA page transitions), and custom HTML/PHP sites. Every installation is followed by a cross-template coverage check — we verify the snippet loads correctly on the homepage, internal pages, product or service pages, category pages, cart/checkout flow, and any other distinct template types. We also scan for and remove duplicate GTM snippets that are a common cause of double-counted conversions and inflated session counts. Installation is completed in a test environment first when available, with a documented go-live procedure and post-installation confirmation report.
