Many sites that have high traffic can make regular income out of selling simple text links on their sites. Companies like Text Link Brokers act as a dealer for these links and also some sites sell their links direct.
How hard is it to sell Text Links Direct
Theoretically not hard at all, anyone with a paypal account and a website/blog can set up a payment page that allows potential advertisers to see what they are buying and immediately purchase it online. The hard part is letting advertisers know that you have text links for sale, however if your site is popular enough they will come to you.
How much money can be made from a single Text Link
I have seen sites charge 100-200 US dollars a month for a single text link on their site, however these are high traffic sites. Myself I charge $10 per month at this early point in the traffic life of my sites.
