Many business owners I meet with are still not using their websites to measure the effectiveness of their off line advertising. It's simple to do and will save/make you hundreds, even thousands of dollars. How? First, design a page on your website specifically for tracking purposes. In your offline advertising design an ad that directs people to that specific page, say to an online coupon. You can then measure if people are actually visiting that page. Move your marketing dollars over to those ads that are actually working. You'll not only stop wasting money, your extra focused marketing dollars will increase your revenue even more.
