Google Analytics 4
- Open
analytics.google.com and sign in. - Admin (⚙) → Create → Property.
- Enter the site name, time zone and currency.
- Under Data streams choose Web and enter your URL.
- A Measurement ID appears in the form
G-XXXXXXXXXX.
Put it in General settings → Tracking & pixels → GA4 Measurement ID.
Google Tag Manager
- Open
tagmanager.google.com. - Create account → enter your company name → choose Web.
- You get an ID like
GTM-XXXXXXX.
Put it in the GTM Container ID field.
Which should you use?
- One or two pixels only: put them straight into nqdr.
- Several tracking tools you want to control yourself: use GTM alone and install everything inside it.
Never put the same pixel in both nqdr and GTM — events will double and your numbers will be wrong.
