Skimlinks is the easiest service for adding affiliate links to your website or blog.

You can create a normal link to any product on a participating shopping website (say Amazon) and Skimlinks will automatically convert them into an affiliate link. Skimlinks works on a revenue share model and the split is 25/75 – they keep 25% while the publisher gets 75%.

The affiliate links are not rewritten and therefore site visitors clearly know where that links will lead them to.

Skimlinks also offers short URLs for your affiliate links to help you earn commissions on links that you share on Twitter, Facebook and email newsletters.
