Implementation recommendations

Google Tag Gateway

Premium

1 Cloudflare domain access. Confirm the client's domain is on Cloudflare (or move DNS). Ensure admin access and the domain is active.
2 Consolidate all tags into GTM. Move every platform tag (GA4, Google Ads, Meta Pixel, LinkedIn, TikTok) into one GTM container before initiating GTG. Remove any hardcoded scripts.
3 Initiate from GTM Admin. In GTM, go to Admin → Google Tag Gateway → initiate setup. Links your GTM container to the gateway.
4 Configure in Cloudflare. Install the Google Tag Gateway app in Cloudflare. Enter your Tag ID (GTM-XXXXXX), set a Measurement Path (e.g. /sgtm), and enable Set Up Tag (auto-retagging).
5 Remove legacy scripts. Once GTG is active, remove any direct Google/Meta pixel scripts. All traffic routes through the gateway. Cloudflare auto-rewrites gtm.js references.
6 Validate with the healthy endpoint. Fetch yourdomain.com/[measurement-path]/healthy — response body must be exactly "OK". Use the checker above.
7 Confirm in Tag Assistant. Open Tag Assistant in Chrome. GTG-routed events show a Cloudflare icon next to the tag. Verify GA4 and Google Ads events fire correctly without direct googletagmanager.com requests.

Standard GTM setup

Baseline

1 Install GTM container. Add the GTM snippet to <head> and <body> of every page. One container per domain — avoid multiples.
2 CMP + Consent Mode V2. Install a CMP (CookieBot, OneTrust or CookieYes) and configure Google Consent Mode V2 in GTM. Required for EU compliance and modelled conversions.
3 GA4 tag via GTM. Set up a GA4 Configuration tag using the measurement ID (G-XXXXXXXXXX). Enable Enhanced Measurement. Configure key conversion events.
4 Google Ads conversion tracking. Add a Google Ads Conversion Tracking tag in GTM using the AW-XXXXXXXXX/conversion_label format. Match triggers to actual conversion actions.
5 Meta Pixel via GTM. Add Meta Pixel tag using the pixel ID. Fire PageView + key events (Lead, Purchase). Implement CAPI server-side for deduplication.
6 Additional platforms. Add LinkedIn Insight Tag, TikTok Pixel, Microsoft UET via GTM as needed. All in one container, all governed by consent triggers.
7 Validate in GTM Preview. Use GTM's Preview & Debug mode to confirm all tags fire on the correct triggers. Cross-check in each ad platform's conversion dashboard.
