It also allows you to easily buy links with the money you earn from selling links, making it a good link exchange market. You can rack up a good daily revenue selling text links with TNX. Read below for instructions and more details.
They have a code snippet available in PHP, ASP and Perl. Their automatic system sell links for you. You can add the code snippet to your footer to sell links on it. You can also place it in the beginning of your page's file and place the text links generators in various locations.
Ok, so you've installed the code snippet in your template. Now what? They will verify your site. When accepted, you'll need to increase the maximum number of text link ads per page, if you wish to do so. You can sell up to 4 links per page. They will sell one text link per page per default. (You will earn as much per link if you sell 4 per page.)
Now the code will index pages that are visited and start selling links on it. This is a completely automatic process. If one of the page have PageRank, you will be able to browse around there advertisers database and add one of their links with a click of a button. This is not available for PageRank 0 pages.
Every day, the links you are selling will be counted and credited to you in points. You are not paid monthly unlike other text link ads networks. You can either purchase back text links with your points or sell them. You can get paid by Paypal Masspay, which means you will not get Paypal fees on any money you earn. Selling links is more than just getting a revenue. It is a good way to pay for your domains, hosting and other maintenance fees.
Since you can use your earnings to purchase links from completely different websites than the ones you have links to, TNX is a great place to exchange links! Since the websites linking to you are not the websites you link to, it gives you one way text links which are usually considered better than regular link exchanges because it is not as obvious for search engines, unlike websites linking between each others. Ideal for all your link building needs.
Note that you sell text links on a per page basis and not site wide links. Which mean you will be selling more text links across all your pages. A high PageRank homepage usually means many subpages with lower PageRank which will also sell text links. Selling text links is a good source of revenue. It does not require any traffic or click like traditional ads. Some may get only a few cents per day, but If you have numerous websites or good Pagerank, you could make many dollars per day selling links. In my experience, it usually range between 0.05 USD and 20 USD per day, depending on the user. Here is a view of my current income:
