What Is a Material Connection?
A material connection is the relationship — a commission, a free product, a business tie — that triggers your duty to disclose. Learn exactly what counts.
A material connection is any relationship between an endorser and a seller that might affect the credibility the audience gives to the endorsement. The concept sits at the center of affiliate compliance because it is the trigger: when a material connection exists and the audience would not reasonably expect it, disclosure becomes mandatory.
Connections that must be disclosed
The category is broader than many affiliates assume. It is not limited to cash payments. A material connection includes:
- Affiliate commissions — you earn a percentage or flat fee when a reader buys through your link. This is the defining case for affiliate marketers.
- Free or discounted products — gifted items, review units, and complimentary services, even if you were not asked to post about them.
- Paid sponsorships and flat fees — direct payment to publish or promote.
- Bonuses and performance incentives — contests, tiered commissions, and prizes tied to sales.
- Business relationships — you own, work for, or consult for the seller.
- Family and personal relationships — a close connection to the person or company behind the product.
Free products count
A common and costly misconception is that only paid cash arrangements require disclosure. Regulators in the US, UK, EU, Canada, and Australia are explicit that gifted products, review samples, and even unsolicited items create a material connection the moment you promote them.
The “reasonably expect” test
Disclosure is required when the audience would not already expect the connection. If a reader lands on a brand’s own website, they expect the brand to praise its products; no disclosure is needed there. But when a recommendation appears on what looks like an independent blog, review site, or personal social account, the audience assumes independence — so any commission or compensation must be revealed.
Why the trigger is easy to hit
For a working affiliate, virtually every monetized recommendation involves a material connection. If your business model is to earn money when people buy through your links, then by definition you have a material connection on every one of those links. The practical consequence is simple: build disclosure into your standard workflow rather than treating it as an exception.
