Ratios in Advertisments

This ad is more of an infomercial. In it, two men are explaining how to sell what ever is on your website. One man uses a 30:1 ratio. He says for every 1 dollar you spend on your website, it's 30 times more valuable than any dollar you can spend someone else. The idea is that if you make your website more accessible, every dollar you spend will be 30 times more valuable in the long run.
