A great way to make money online is to come up with an idea no one else has yet, or one that has been done poorly. This is why niche blogging has become so popular and lucrative. Google has helped many make money from their visitors and helps just as many gain visitors they wouldn’t otherwise have had.

Roomster.net has taken a simple need, such as finding an apartment or a roommate, and created a fully interactive website visitors to get what they’re looking for quickly and efficiently. Adding photos and profiles for the users made the service more personal and easier to use.

They’ve made use of Google Maps so you can see not only the location, but the surroundings, right from your computer. And they have a quick messaging feature that allows to you message potential roommates, or receive messages without having to share your email address with the public. Keeping your members’ and their information safe is a great way to earn trust.

I like that you have to register or log in to do anything on this site, except to see the listings. If your visitors have to register to even look, it’s likely they’ll leave the site altogether. They have a great balance public and private information, as well as a great userbase. You can see from the front page that this site is used often and by many. Take a look and gain some inspiration. And possibly even find yourself a new roommate.
