Google Analytics Checker
Verify Google Analytics (GA4/Universal) installation and tracking.
Frequently Asked Questions
How do I know if Google Analytics is installed correctly?
This tool checks for the GA tracking code in your page source. A properly installed GA4 setup will have the gtag.js script with your Measurement ID (G-XXXXXXXX) loading on every page.
What is the difference between GA4 and Universal Analytics?
GA4 is Google's current analytics platform, replacing Universal Analytics (which stopped processing data in July 2023). GA4 uses event-based tracking instead of session-based, with better cross-platform measurement.
Does Google Analytics affect page speed?
The GA script adds a small overhead (typically 20-50ms). To minimize impact, load it asynchronously using the async attribute, and avoid adding too many custom events on page load.
