Some newspapers are charging more for classified ads that mention a web site. If you just list a URL (in a cheap one-line ad), they’re losing money since you aren’t describing your services with more text. This is an interesting example of the valuable nature of domain names and descriptive urls. As the Wired article points out, the same thing happened when 1-800 numbers became popular. My question is: for classifieds that are online, will the newspaper charge you more to have a live link to your URL or is that included in the cost? (and does that really matter since browsers could be programmed to pick up the URL as a link anyway?) As newspapers continue their evolution into online “print”, ad revenue models must evolve along with them.
