I came across this free advertising service called adgridwork.com that allows you to display a few text links on a page in exchange for your text link being shown on other sites around the world. This looks very promising, so I decided to give it a try, you can see the links down in the right sidebar at the bottom. The ads are fairly unobtrusive and not obnoxious, the best part is it’s free. If this sounds good to you please use this link and sign up for their service.
