Where'd you get five bucks? I want five bucks.
The idea was to capitalize on people misspelling URLs. It's pretty easy to type 4cgan.org, right? It turns out that thousands of people do it every month. In fact, if you register 4cgan.org, you'll see something like 40,000 hits per year.
A business model emerges. Apparently, one can expect about 3 to 4 dollars per 1,000 impressions in ad revenue. \(40,000 \cdot $3.50 / 1,000 = $140.00\) per year. Given that a domain costs something like $12.00 per year to register, this is a tidy profit, even considering potential hosting costs.
Ever wonder why there are all those janky ad-laden sites with mangled URLs? Odds are, those URLs are one mistyped character away from something that pulls a lot of traffic.
This morning I sat down, generated a bunch of misspellings for popular sites, checked whether they were available, then ran the misspelling through Google's Adsense keyword search to get a sense of search volume (which I took to be equal to direct entry of the URL, although that's arguable).
The result? I'm about a decade too late - anything profitable under this model is already registered. The market is saturated. Oh well.
