Your business web site can be much more than just an electronic billboard or business card. With the right strategy, it can act more like a highly effective employee (and a relatively cheap one at that).

Many web sites exist only to tick off a box on the business owner check list. Don't let yours be one of them. No matter what your business is, your web site can do more.
