CONTENT · SEO GLOSSARY
Affiliate Disclosure
The legally required and SEO-positive statement informing readers that a content publisher receives compensation (affiliate commissions) when visitors purchase products through links on the site — required by FTC guidelines and consistent with Google\'s E-E-A-T trustworthiness standards.
Definition
An affiliate disclosure is a statement placed on web pages containing affiliate links that informs readers of the financial relationship between the publisher and the merchants being recommended. The FTC (Federal Trade Commission) in the US and similar regulatory bodies in other jurisdictions require clear and conspicuous disclosure of material connections between endorsers and the products they recommend. For affiliate publishers, this means: any page with affiliate links must clearly state that the publisher earns commissions on purchases. FTC "clear and conspicuous" requirements: the disclosure must be in a prominent position (not buried in fine print or hidden at the bottom of a page the user may not read), in plain language ("this post contains affiliate links; I earn a commission if you buy through my links"), and present before the user encounters the affiliate links. SEO implications of affiliate disclosure: (1) **Trustworthiness signal** — Google\'s quality rater guidelines explicitly assess whether sites clearly disclose their monetisation. Hidden monetisation is a negative quality signal; clear disclosure is positive. (2) **E-E-A-T support** — the "T" in E-E-A-T includes transparency about the site\'s purpose and commercial relationships. (3) **No ranking penalty for disclosure** — affiliate disclosure does not penalise organic rankings; it is a neutral-to-positive signal. (4) **Nofollow on affiliate links** — Google\'s guidelines recommend (and have evolved on) nofollow or sponsored rel attributes on affiliate links to signal that the link is a commercial endorsement rather than an editorial citation. Most reputable affiliate programs include these attributes in their link code.
Why it matters for SEO
Affiliate disclosure is both legally required and an E-E-A-T trustworthiness signal. Sites without clear disclosure risk FTC enforcement action (for US publishers) and negative quality ratings from Google\'s raters who are specifically instructed to look for hidden monetisation. Sites with clear, prominent disclosure signal editorial integrity — even in commercial content — which supports long-term topical authority.
How DeepSEOAnalysis checks this
DeepSEOAnalysis does not check for the presence of affiliate disclosure text (which requires content understanding). However, the audit checks for `rel="sponsored"` or `rel="nofollow"` attributes on outbound links — which are signals of properly marked affiliate link relationships. Structured data checks also confirm that Review schema ratings are not manipulated (a form of deceptive commercial content that disclosure doesn\'t fix).
