What Is Self-Hosted Google Analytics v4?
Self-Hosted Google Analytics v4 is a performance-focused alternative to the standard Google Analytics tracking setup. Instead of loading the analytics script from www.googletagmanager.com on every page, you self-host the tracking script on your own server. The analytics data still flows to Google Analytics; only the script delivery changes.
The feature offers two trackers:
- Minimal Analytics (1.4KB): A custom lightweight script that tracks pageviews only. Fastest possible load.
- Gtag.js (90KB): The standard Google Analytics library, self-hosted. Full feature parity with the standard implementation.
Why You Need It
Loading Google Analytics the standard way means a third-party request to Google’s servers on every page view. This has three costs:
- Performance: A blocking or render-delaying request to a third-party domain, often flagged by PageSpeed Insights
- Privacy: Ad blockers and privacy-focused browsers can block the request, leading to incomplete analytics data
- GDPR concerns: Loading scripts from US-based servers triggers consent requirements under some privacy frameworks
Self-hosting eliminates the third-party request, keeps the analytics data flowing, and lets you choose the size tradeoff.
How to Enable Self-Hosted Google Analytics v4 in Classic Monks
Step 1: Navigate to Settings
Click into the Classic Monks plugin settings in your WordPress dashboard.
Step 2: Go to the Core Tab
Click on the Core menu. The Setup subtab opens by default.
Step 3: Toggle On “Self-Host Google Analytics v4”
Find the Self-Host Google Analytics v4 toggle and turn it on. The configuration panel expands.
Step 4: Enter Your Google Analytics 4 Measurement ID
In the expanded panel, enter your GA4 measurement ID. The format is G-XXXXXXXXXX (10 characters after the G- prefix). Get the ID from your Google Analytics admin under Admin > Data Streams > Web.
Step 5: Choose a Tracking Script
Select either:
- Minimal Analytics.js (1.4KB) for ultra-fast pageview tracking
- Gtag.js (90KB) for full GA4 features (events, conversions, custom dimensions)
For most content sites, Minimal Analytics is sufficient. For e-commerce or sites that need event tracking, choose Gtag.js.
Step 6: Decide on Admin Exclusion
The Disable for logged in admins toggle is on by default. When enabled, administrators browsing the site do not trigger analytics events, keeping your analytics data clean of internal traffic.
Step 7: Save Changes
Click Save Changes. The tracking script loads on the frontend, and analytics data starts flowing to your Google Analytics property.
Configuration Options
| Option | Description | Default |
|---|---|---|
| Self-Host Google Analytics v4 | Master toggle for self-hosted tracking. | Off |
| Google Analytics Tracking ID | Your GA4 measurement ID (G-XXXXXXXXXX). | Empty |
| Tracking Script | Minimal Analytics (1.4KB) or Gtag.js (90KB). | Minimal Analytics |
| Disable for logged in admins | Exclude administrators from tracking. | On |
Minimal Analytics vs Gtag.js
| Feature | Minimal Analytics (1.4KB) | Gtag.js (90KB) |
|---|---|---|
| Pageview tracking | Yes | Yes |
| Event tracking | No | Yes |
| Custom dimensions | No | Yes |
| E-commerce tracking | No | Yes |
| Cross-domain tracking | No | Yes |
| Load time impact | Negligible | ~90KB download, parse time |
| Ad blocker resistance | Higher (custom script) | Lower (well-known gtag.js) |
| PageSpeed Insights score | Minimal impact | Slight impact |
Recommendation:
- Content sites, blogs, portfolios: Minimal Analytics is enough. You need pageviews; you do not need events.
- E-commerce, SaaS, lead-gen sites: Gtag.js. You need conversion tracking, enhanced e-commerce, and custom events.
- Mixed sites: Start with Minimal Analytics, upgrade to Gtag.js if you need features it lacks.
Developer Notes
The self-hosted analytics feature is loaded conditionally via cm_initialize_self_hosted_analytics() in functions/core/analytics/self-hosted-analytics.php. The script is enqueued only when enable_self_hosted_analytics is on.
Options used:
| Option | Type | Default |
|---|---|---|
enable_self_hosted_analytics |
Boolean | false |
analytics_tracking_id |
String | Empty |
analytics_script_type |
String | minimal-analytics |
analytics_disable_for_admins |
Boolean | true |
The tracking script is loaded via a standard WordPress wp_enqueue_script() call. The Minimal Analytics script is an inline script; Gtag.js is loaded from a local copy.
Troubleshooting
Tracking Not Showing in Google Analytics
Cause: Measurement ID is wrong, tracking script is not loading, or caching is serving stale pages.
Fix: Verify the ID in the GA4 admin. Clear all caching layers. Test in incognito mode with dev tools open and look for the analytics request in the Network tab.
Self-Hosted Script Still Loading from Google
Cause: The browser cached the original gtag.js from Google’s servers.
Fix: Clear browser cache. The script is served from your own domain, but the URL is different from googletagmanager.com, so cached requests to the old URL will not transfer.
PageSpeed Score Did Not Improve
Cause: Other resources (images, CSS, JS) are still the bottleneck.
Fix: Self-hosting GA is one of many optimizations. Check the PageSpeed report for the largest items and address those.
Minimal Analytics Not Tracking Events
Cause: Minimal Analytics tracks pageviews only, not events.
Fix: Switch to Gtag.js if you need event tracking, or implement custom event tracking via Minimal Analytics’s JavaScript API.
