When you think of marketing you probably think “service”. If a website is a form of marketing, why do most companies try to sell you their websites as products? They hand over a static website and say “Here’s your website Doctor, good luck!”, and it just sits there.
A website is like a car. To keep it running smoothly and generating consistent, reliable results, it must be professionally maintained on a monthly basis. It must have it’s oil changed regularly. If you’re like most dentists, you’d probably have more important things to do than maintain a website.
