This requirement is from Amazon’s Associates Program Operating Agreement and is related to transparency, and disclosing endorsements, a legal requirement under many countries’ laws :
You must clearly state the following, or any substantially similar statement previously allowed under this Agreement, on your Site or any other location where Amazon may authorize your display or other use of Program Content: “As an Amazon Associate I earn from qualifying purchases.”–Amazon’s Associates Program Operating Agreement, Section 5: Identifying Yourself as an Associate
This particular disclosure needs to be included in an easily accessible location of your site, best practice would be to include the disclosure clearly and conspicuously on the same page as the particular affiliate link you’re using. The closer this disclosure is to your recommendation, the better.
You represent, warrant, and covenant that (a) you will participate in the Associates Program and create, maintain, and operate your Site in accordance with this Agreement, (b) neither your participation in the Associates Program nor your creation, maintenance, or operation of your Site will violate any applicable laws, ordinances, rules, regulations, orders, licenses, permits, guidelines, codes of practice, industry standards, self-regulatory rules, judgments, decisions, or other requirements of any governmental authority that has jurisdiction over you (including all such rules governing communications, data protection, advertising, and marketing)…–Amazon’s Associates Program Operating Agreement, Section 4: Warranties
They further say:
In addition we may (a) monitor, record, use, and disclose information about your Site and users of your Site that we obtain in connection with your display of Special Links and Program Content (for example, that a particular Amazon customer clicked through a Special Link from your Site before buying a product on the Amazon Site),(b) review, monitor, crawl, and otherwise investigate your Site to verify compliance with this Agreement…–Amazon’s Associates Program Operating Agreement, Section 12: Additional Provisions
You need to comply with applicable law, not just because it’s in your best interest to comply with the law, but also because to choose not to do so can be considered a breach of Amazon’s terms.
