I believe you could do the same thing with a form and a simple bullet or dropdown that lets the potential client identify as education, business, etc. Once submitted, you could be taken to a different landing page based on the responses (bonus points for content relevant to their business).

The more sticky situation would be phone calls if you have a number.

Although using this method doesn't directly attach sales to conversions, it seems it would help qualify leads a little better and hopefully maximize you Adwords spending.
