What is click-to-call?

Click-to-call is a button you can place on your website that lets visitors instantly initiate a phone call with your business—no dialing required. With a single tap on a mobile device, the customer’s phone opens the dialer and auto-fills your business number.

How does a click-to-call button work?

Click to call links use the tel: HTML protocol to activate a device’s native calling application:

<a href="tel:+1234567890">Call Us Now</a>

• On mobile devices: Tapping the link opens the phone dialer with the number pre-filled.
• On desktop: It prompts a VoIP app (like Skype or Zoom) or shows a call dialog.
• Optional: By forwarding you calls, you can connect your button to an AI answering service so that no call is ever missed

How to use click-to -call

You can use click-to-call to make it easier for customers to get in touch with you. A lot of people still prefer calling a business, especially for urgent questions or high-stakes purchases. The easier you make it to call you, the better your chances of winning that customer.

Instead of hiding your phone number on a buried contact page, click-to-call puts it front and center. You can add a floating “Call Now” button in the bottom-right corner of your site, or place a clickable phone number in your website header, contact form, or landing pages.

Here are some common use cases for click-to-call:

• Sales inquiries – Let potential customers speak with someone right away while they’re still interested.
• Customer support – Make it simple for existing customers to reach help without digging through your site.
• Appointment booking – Service-based businesses (like clinics, spas, or repair services) can use click-to-call to drive more bookings, especially with the use of an appointment scheduling answering service.
• Emergency services – Great for plumbers, locksmiths, emergency restoration, and other urgent-response businesses.

How to add a click-to-call button to your website

There are two easy ways to add click-to-call functionality to your site:

1. Create a clickable link

The fastest method is to simply turn your phone number into a link, just like you would with any URL.
Here’s the format:

<a href="tel:+15551234567">Call Us</a>

This will work anywhere you can add a hyperlink—your website header, contact section, footer, or emails.

2. Use our click-to-call button generator

If you want something nicer than a plain text link, at the top of this page you’ll find Upfirst's Click-to-Call Button Generator. It lets you customize:

• Your phone number
• Button text
• Colors
• Rounded corners

Once you generate your button, copy the HTML snippet and follow the steps below based on your website platform.

• WordPress – Paste it into a Text/HTML block on a page, widget, or footer (for all pages).
• Webflow – Use an Embed block for a single page. For all pages, add it to the Footer Code section in Site Settings.
• Wix – Add an Embed HTML element to a page, or use Custom Code in Site Settings to show it site-wide.
• Squarespace – Use a Code Block to add it to one page, or go to Settings → Advanced → Code Injection to place it on every page.

Where you paste the code determines whether the button appears on just one page or across your whole site.
