Each of your visitors has their own preferred method of contact. Studies show that phone and live chat communication are at a close tie with 23% and 21% of participants stating that it is their preferred way to communicate with a business. However, at 54%, email still remains the #1 way in which visitors wish to communicate.
Although phone numbers and live chat should be visible throughout your website, visitors need a central location where they can immediately find out how to contact you via phone, fax, live chat or email.
Include an immediately visible "Contact" button in the main menu at the top level.
