ROI

Hello all,

We use a service called IfByPhone that offers "Dynamic Phone Number Insertion" (DPNI). This is a service that swaps out the phone number on your site based on where the visitor came from. It's like using a different phone number in the yellow pages, on a billboard, and on a TV ad. That way, when you get your phone bill, you can see how many people called you from each ad. This could work similarly with the search engines. Someone came from Google, show them number A. Yahoo, show them number B. Drupal.org, show them number C. Etc.
