1. Sign up for Google's Adsense program.
A good company that converts traffic into revenue. A classy company with a successful program. A plus is that it fits in nicely to any website without making it look trashy. People don't like to be bombarded with ads, so text is a good idea for your own website. That's why I use it. I'm just like you, it's nothing personal, I just don't see that there's anything to lose from gaining a little bit of money no matter what the site is about.
2. Sign up for surveys which pay you to fill them out.
If you've got extra time you may as well sign up an email account which can be designated for this. Advertisers are eager to know what you want to buy, so they will pay good money to gather that information. Once again, I'm not going to promote anyone here. I'll leave it to you to set that up.
3. Sign up for pay-click emails which will pay you for seeing their advertisements.
If you don't mind a few extra clicks you will be able to build up a little extra cash. The more you sign up for the more emails you get - most websites will limit the amount of emails you recieve so that you can't make truckloads, so signing up for different websites is the best way to go about making this avenue of income worthwhile.
4. Sell your excess items online.
Ebay, for example, is a great place to start. You have a lot of stuff sitting around that I'm sure you don't need. I'm sure I don't need to explain the selling tactics but as you know, even if you're only getting a fraction of the original price back in return, there will be more than a handful of suitors willing to pay up.
