If you've got a genuinely useful website that has nothing to do with the 'GetPaid' world (which it sounds like you have), using traffic exchanges is probably not what you are looking for.
Try finding other websites with similar content to yours, if they have a links page, contact the webmaster and ask to have your link added (you could offer to do the same back on your website).
Also, give search engines a while. Although some will have your site indexed within a few days, some will take
months.
If you haven't done so already, go to dmoz.org and submit your site to the relevant category. This (in the long term), will bring you a lot of traffic.
And if you've got money to spend, because your site has specialist content, you could try advertising it in magazines of the same content.
Please PM me the URL of your site and I'll look through it and give you some more suggestions
