If you want to present your user with a simple way to add their location or address while filling out one of your forms, geolocation is a great tool.
Some form builders offer a geolocation add-on that allows you to add geolocation fields to any form, or or anywhere you need it. It usually comes with an autocomplete field powered by the Google Maps API.
This function even saves fully geocoded data in the form entry and the saved data can be outputted on any map for further analysis.
Aggregating user data like the address can help you make more informed decisions about your campaigns and organizational strategy.
