Untargeted Traffic is Waste of Bandwith

Traffic to your website means nothing if it is not targeted to your specific product, program, opportunity, or business. In order for traffic to be most effective, it must be targeted to your specific market, program, product, etc.
If they’re not targeted, they’re wasting bandwidth.
