Does your website have your email and phone number at the bottom of every single page?
Yes, it will generate more calls and emails- from people who probably want to do business with you.
It may be worth your time.
To go even further- do you have an FAQ that’s easy to find? Is your menu of services up to date? If visitors like your offerings, is it easy for them to download the paperwork they need or use your shopping cart mechanism?
It seems obvious, but almost daily I encounter someone who has made the buying process hard for no good reason.
