How to Add Google Analytics to Your Website Correctly
Create a GA4 property, install the tag once in a place that loads on every page, and verify with realtime reports. Installing it twice double-counts every visit.
Have this ready
- A GA4 property and measurement ID
- Access to edit the site's head or tag manager
- A consent approach if required in your market
Step by step
- 1Create a GA4 property and a web data stream for the exact domain, including www or non-www as used.
- 2Copy the measurement ID and install the tag once, ideally through your site's layout or a tag manager.
- 3If your site already has another analytics tag, remove the duplicate rather than adding a second copy.
- 4Open the realtime report and confirm your own visit appears.
- 5Mark key actions as conversions, such as signup, checkout start and purchase.
- 6Add your consent banner settings before collecting data where the law requires consent.
- 7Set a data retention period and an internal note on who owns the property.

I can walk you through it in a Magic Box, show you the exact clicks, or do it with you and keep the recording. You log in yourself; I never see your password.
Common questions
Why are my numbers different from another tool?+
Blockers, consent choices and different attribution rules all change counts. Small differences are normal; large gaps mean a broken tag.
Do I need a cookie banner?+
In the EU and UK, analytics cookies generally need consent. Check the rules for your visitors, not just your own country.
Can I track a single-page app?+
Yes, with the enhanced measurement setting or manual page view events on route changes.
