How to Create a Tap-to-Call Button
A tap-to-call button gives smartphone visitors a fast way to contact your business directly from your website. Instead of copying or remembering your phone number, they can tap the button and begin a call using the number you have assigned to it.
Set the Button Link Type to Tap-to-call
Open the settings for the button you want to use. Find the Link Type setting and choose Tap-to-call. This tells your website that the button should be connected to a telephone number instead of another page, website address, or email action.
