I'm using a couple of parasite sites to rank and want to use the traffic to convert some affiliate sites. I'm using Amazon and some niche specific affiliates. Is it a good idea to shorten the affiliate links when linking to the product with like goo.gl? I read somewhere that Google and Web 2.0s don't like affiliate links and can cause de-index quicker. EDIT: What's URL shortener do you guys recommend to track multiple links?
