Stupid Question - affiliate links

This is a silly question Im sure. But in short is it OK to use the affiliate link that is supplied like the "hop link" or should I cloak it? Is that the right terminology? I am finding that my posts arnt getting indexed as quickly as they used to. txs..

Dont ever use it straight up. You are going to scare away any possible customer with that virus looking thing

Just run through bit.ly is ok? Meaning more for google?
