It’s also very essential to think about disclosure. Guidelines from the Federal Trade Commission FTC state you must essentially divulge your affiliate relationships in your blog in a way which could be easily noticed by readers. This means you are looking to make it very clear to readers from the outset that in the event that they click the links in your post and purchase, you’ll get a commission. Note that having the disclosure after the post or on a separate page is regarded inadequate; your disclosure must be clear and accessible before a reader starts browsing at the post.
The FTC checklist apply to all web content promoting to US residents – so if your site has US readers it almost certainly does you should definitely comply.
