Website designer and website builder are often used interchangeably, but the two have several minor yet important differences.
A website builder’s main goal is to construct a functional website. To do this, they typically use done-for-you tools (think drag-and-drop features, templates, etc.). The website is usually completed a little faster, but in most cases, they look like just about every other website using those same tools and templates. This does little to help your business stand out, plus it might not deliver the custom experience and impact you need it to.
