You should disclose when linking to affiliates
I despise seeing bloggers or sites in-line link using their affiliate codes without disclosure. I don’t mind helping others turn a quick buck on something they really believe in, but recommending without disclosing affiliate participation feels counterfeit. Either physically separate your affiliations from your posts and label them as such, or disclose. The long-term benefits of straightforwardness are far greater and lasting than the the few bucks you may or may not earn from an affiliate link. A quick roll over is all it takes to get busted, so link responsibly. I promise you’ll earn just as much if not more by disclosing your affiliates when linking. Believe it or not.
