If the search engines send you repeat organic traffic, it is FREE. It cost you nothing to convert those people in to customers because you paid nothing for them to visit your site. The search engine sent them to you at no cost.
The search engines don't SEND people to your site any more than the Yellow Pages SEND people to physical stores. They just make people aware that you exist. And then you've got two or three lines to convince them that you're more desirable than the people immediately above and below you. Or twelve square inches to show how attractive you are.
