When smartphone users are on a website, they expect that tapping a phone number will automatically dial it. So make sure that’s the case with your site.
Well, first you should make sure that, if it’s important to your business, your phone number is highly visible on your site. This is crucial not just for visitors, but also for search engines, which use the number as part of their verification of your location for local search purposes.
Then of course, you should test the click-to-call functionality. If you can, test on multiple devices; if you have an iPhone, find an Android device to test, or vice versa. Ask friends to check on a device you don’t have.
Many mobile browsers will automatically detect phone numbers, but don’t leave it to chance. If the telephone link does not work, talk to the person who set up your site or whoever manages it now. They need to put the proper coding in place:
<a href="tel:+1-555-555-1212">+1 (555) 555-1212</a>
