Cost of Living Difference Calculator
This is a cost of moving calculator for any two points in the US. It is useful, but as a website provider this is not as attractive at all.
The Reason is simple. PayScale’s widgets pull users away from your website to Payscale and in the worse possible way. Instead of displaying the data on your site, Payscale does not create a new browser page but replaces your website with their results. Not a winning formula.
