If you advertise on twitter and post the link do u use anything to make it look not so hidious? With all those letters and numbers and junk... and to make it shorter.. It gets denied from every link shortener site i try..

TinyURL via adf.ly

ya but i want something free that doesnt put ads.. like goo.gl or but.ly

Say what? Why on earth would you pass getting money both from Adf.ly AND your product? Just use bare tinyURL in that case...

Putting affiliate links in your tweets will get your twitter account suspended for violating terms of service. Instead link to a youtube video or review site with your affiliate link in description.

I buy a cheap .info domain (2-3$) and redirect my link with that. If looks much nicer than any URL shortener
