  • Optimizing event tracking with multiple gtag codes in Google Analytics 4 (GA4)

    Posted by Sofia on 23 April 2022 at 2:23 pm

    So, I’m working with two different gtag codes in my project. Each event I send out is recognized twice in the analytics reports although I send it only once per gtag. My suspicion is that calling gtag(‘event’,…) for each gtag, without specifying the gtag in the function, might be messing things up. Is there a way to call gtag(‘event’,…) for just one specific gtag? Or any other way to sort this out?

    It seems like you might be experiencing a common issue with Google Analytics tracking known as “double-counting”. This often happens when the gtag.js (Global Site Tag) is implemented more than once on a page. When you call gtag(‘event’,…), the event is sent to all currently configured tracking IDs, which may lead to double-counting if multiple instances of the same tracking ID are present.

    To avoid this, you should try to ensure that each Google Analytics tracking ID is only implemented once on your page or site. You could do this by carefully managing your tracking code implementation or, if possible, using a tool like Google Tag Manager to help you manage multiple tracking tags.

    In cases where sending an event to a specific tracking ID is really necessary, you can use the “send_to” parameter in the event call to specify which ID to send the event to (for example, gtag(‘event’, ‘event_name’, { ‘send_to’: ‘GA_TRACKING_ID’ }).

    This issue can require complex debugging depending on your specific implementation, so you may want to consult with a professional with experience in Google Analytics implementation to help you sort this out.

    You’re correct in surmising that it may be due to not specifying exactly which Google Analytics property you wish to send the event to. When you call gtag('event',...), it sends that event to all configured properties, hence the double reporting. To send an event to a specific property, you should use the following syntax: gtag('config', 'GA_MEASUREMENT_ID'); followed by your desired gtag('event',...). Remember to replace ‘GA_MEASUREMENT_ID’ with your actual Google Analytics Measurement ID. This will make sure that the event is sent only to the specified property.
