Thanks to the restriction on the length of posts in nanoblog services like Twitter, the world needs URL shortening services like TinyURL and similar sites. The shortening services are free, though. So one has to ask, how do they make money? And where's my cut?
There are (at least) two URL shorteners that are ad-supported. Not only do they have a revenue model, but they share their revenues with people who use them.
The new kid on the block here is Adjix. Like TinyURL, it creates short links. But the pages users get directed to get a small ad frame above the content. People who create Adjix links get reimbursed at a $0.10 CPM (cost per thousand), or $0.0001 per link. Clickthoughs on the ads pay off at $0.20 each. Advertising is sold at a $0.35 CPM with a $0.75 click-though fee. That's a nice margin for Adjix.
The older LinkBee also pays for referrals. Rates are not listed on the site, but the company claims a 50 percent revenue share, better than Adjix. LinkBee top banners are bigger and more intrusive than Adjix, but the service also offers the option of putting interstitials (also called "blocker ads" by people who hate them) in front of destination pages. While annoying to some, interstitials don't change the experience on the destination site, or interfere with sites' own advertising programs once you get to them.
For its part, TinyURL creator Kevin Gilbertson is on the record stating that he could make a million dollars a month, "if he chose to attach a pop-up advertisement on each URL," according to his hometown paper, the Minneapolis Star Tribune. "But he won't, on principle," the report says. TinyURL instead makes revenue from Google ads on the its main site. That works when you have traffic at the TinyURL volumes; it wouldn't work so well for newer services. There's no revenue share model on TinyURL.
Ad-supported URL shorteners make economic sense, but only if you don't look too hard. Open your eyes beyond a squint and you realize that people who share URLs via shorteners are likely doing so to get some value out of the traffic that they already understand, whether it's ads on the site they are linking to, or spreading their marketing message, or simply sharing what they love with people they like. Putting an advertisement in front of that transaction can reduce the value of the link. With the low pay-back from the monetized shortened links, users could actually end up losing money with these services instead of making it.
As a tool for spammers, though, monetized short links make a ton of sense. But for everyone else, not so much.
