For the start, You're going to need to have a domain, Create a catchy domain name and easy to remember may give you a good result.
For example, Try to create a domain that less than 3 words. And the last word might end up with "cams". You may notice that almost all big webcam sites have only 3 words in their names such as myfreecams, bongacams, chaturbate, livejasmin. It's easy to remember and perharp easy to type on browser when someone finds your videos and need to go to your site. Also it's good when you are going to watermark your videos. You'll have more space and able to get a good position to place the watermark on the videos.
After finished registering a domain name. You may need to put some contents on your website. Because it is important when you are going to sign up on affiliate networks. Some network may required your information about your domain name and you have to describe how are you going to send them a traffic. Some may don't. But it looks better if you have some contents on your site to show them while your application is on appproval process.
After You've got approved on a network. You should see the offers in their sites. And you may realize that there will be a countries retriction for each offers. Such as they will only pay you for US,CA,AUS,DE traffic for example. Which means even you have many people signed up on your offer but they are not from those countries. You will not earn the money at all. Even those registers are match the coutries offer. The network will choose and pay you only high quality traffic which called "lead" in your dashboard. This means you may get only 4-5 leads from 100 hits for example.
This method is a long term work and need to be patient. You may find many problems occured during doing this. Such as videos getting removed from tube sites, Account getting banned, Videos don't appear after uploaded and whatnot. But you'll learn many things while doing this if you are a beginner. And of course you can earn money from this method. It's all depends on how much time can you spend doing this and how many quality traffic you can send to the network.
If you really want do this method, I suggest you to do it like a hobby when you have time and don't expect too much. So you will not be frustrated and quit when the result doesn't meet your expectation. Everyone is having a good day and bad day while doing this just like the other methods. But it's worth to try because you have nothing to lose except your domain cost.
