You used to be able to buy an expired adult domain and monitize that traffic. Back in 2007 I got 4x adult .info names that was part of an expired adult Network and got around 200 eur from each in 2 months. They were parked at sedo.
Today all those clicks would be worthless.. So no things have most definitely changed.
Interesting. Why would they be worthless today? Has the payout per click gone down significantly or is there another factor?
I can tell you one thing I know that makes parking less profitable...many park pages don't load in for me becuase I use the AdBlock plugin. The page is completely blank unless I deactivate the plugin for that domain. Use of ad blockers is getting more popular every day. These parking companies need to redesign/re-code their pages to circumvent adblockers. I'm sure it can be done. Anything is possible if you put your mind to it. Adblockers are great for web surfers, but they are causing advertisers to lose revenue so that makes sites turn to pay walls and such. It s a catch 22. I guess if you want a free internet, you have to be willing to lose some security. Freedom was never free.
