Make it easy.
WHAT TO INCLUDE
Phone number, as text so it can be tapped on a phone Email address, or a form Physical address, if you have premises Opening hours A map, if people visit you
What to expect: how quickly you reply
A FORM OR AN ADDRESS
Both. Some people will use a form; others prefer to email or call directly.
A form alone, with no phone number, looks evasive.
KEEP THE FORM SHORT
Name, email, message. Add a phone field if you need it.
Every additional field loses some proportion of people. Ask for what you need to reply, not everything you might eventually want.
SET EXPECTATIONS
"We reply within one working day" reduces the anxiety that causes people to also phone, and to phone again.
For many Nigerian businesses, a WhatsApp link converts better than a form. Include it if someone will actually answer.
AFTER SUBMISSION
Show a confirmation, and send one by email. A form that appears to do nothing makes people submit twice.
TEST IT
Monthly. Forms break silently.
