# Google Analytics 4 ### GA4 Script Tag If you have added the GA4 Script Tag directly to your page's HTML, Optibase will automatically detect it and trigger an event when a Variant is shown to a user. You do not need to connect Google Analytics to Optibase for that to happen; if you have Google Analytics set up on your website in that way, that is Optibase's default behavior. The event that Optibase will send will have the name: `optibase_variant_shown`, event\_category `optibase`, and event\_label: `{testId:variantId}`. ### Google Tag Manager If you have added GA4 through the Google Tag Manager, you must manually set up the trigger and a custom tag. Follow this guide to do that: [Google Analytics 4 with GTM](/integrations/google/google-analytics-4-with-gtm.md) ## Audiences You can connect your Google Analytics account and property to Optibase by going to the integrations page in the Optibase Web app. As mentioned before, you do NOT need to connect Google Analytics to Optibase to start collecting events mentioned above.

More about Google Analytics Audiences: To automatically create an audience for Variants in a Test for Google Analytics: 1. Connect the Google Analytics account and property you have setup above. 2.
