Using a 301 redirect is the most efficient and Search Engine Friendly method for affiliate link redirection. It is not hard to implement and should improve your search engine rankings. The code "301" is interpreted as "moved permanently". It's the equivalent of filing a change of address with the post office. With a 301, you are telling the search engines that the affiliate link they are following has been permanently moved to the merchant's homepage. And that, in turn, causes the search engines to credit the inbound link to the merchant's homepage.

Below are a few methods to implement an SEO friendly affiliate link redirection.
