WHAT DOES THE PLUGIN DO?
This plugin places a Call Now Button (click-to-call button) to the bottom of the screen which is only visible for your mobile visitors. Because your mobile visitors already have a phone in their hands this plugin will allow them to call you with one simple touch of the button.
No more navigating to the contact page and no more complicated copy/pasting or memorizing the phone number!
COULD NOT BE EASIER!
The settings are very easy: enable and enter your phone number. That’s it!
If you want to add some text to your button, that’s possible. Entering text is fully optional – leaving it empty will show a nice circular phone button to your visitors (have a look at the screenshots).
NEED MORE CONTROL?
Under the Presentation tab you can change the color of the button, move it to a differet location on the screen and limit the pages on which the button should be visible.
Under the Advanced tab you’ll find a bunch of settings that allow you to enable click tracking in Google Analytics, fire a conversion tag so a call is registered as a conversion in Google Ads, adjust the size of the button or move the button further backwards in case you want something else to sit on top of it (e.g. your privacy notice).
FOR MOBILE OPTIMIZED (RESPONSIVE) THEMES
The button is super light and fully build in CSS. The only requirement is that your website’s theme is responsive, meaning it adapts to the size of the screen.
