I am often asked what the difference in cost is between pay-per-click (PPC) and organic SEO. As obvious as it is to me what the differences are, when I try to explain it to others who are not as "nerdy" as I am, often the response I get is the deer in the headlights look. Mostly people think that you have to pay for ads on Google, Bing, etc., and not for organic first page rankings. Not the case.
Over time, I have attempted dozens of analogies to explain the differences between the costs of first-page placement for organic and PPC. I think that I may have finally found a way that helps people understand and that they can easily relate to- the cost of an athlete versus a non-athlete going to college.
