Couple days ago I received my July payment from Text Link Ads, transfered directly to my PayPal account. I know it's not much, but this shows you another way to earn money online.
Have you joined Text Link Ads? If you had website or blog with rank which is not that bad (at least your Alexa is not more than million or the pagerank is not zero), you should consider to join Text Link Ads. The earning is not bad.
All you have to do is register, then submit your blog. Wait until they approve your blog. Then after that, they will put your site in their marketplace. After this point, there's nothing you can do except waiting for advertiser to buy link in your blog.
The revenue that you will get is 50% of your price. And the payment will be made via PayPal. Try your luck and sign up today!
