A useful distinction
A disclosure can be overlooked when it is far from the recommendation or appears only after the reader follows a link. Layout therefore affects communication. A site-wide footer is a different location from the decision point in an article.
Put it into practice
Review a fictional page in reading order and note when the compensated recommendation appears. Check that the explanation is available there in normal text. Do not rely on a hidden menu, hover state or a separate article to provide information a new reader needs in this context.
