GTM server-side Client fetching current weather conditions from an OpenWeather API
Years ago I read the first articles about sending weather tracking as extra data in Google Analytics tracking hits.
If I’m not mistaken, one of the first ones was this one written by Simo Ahava: https://www.simoahava.com/web-development/universal-analytics-weather-custom-dimension/.
Weather data is as a great addition to web analytics implementations on a lot of different types of websites.
As an example, companies in areas like travel and hospitality could benefit from using it.
