Q: What if all I get from a company is a $1-off coupon, an entry in a sweepstakes or a contest, or a product that is only worth a few dollars? Does that still have to be disclosed?
A: The question you need to ask is whether knowing about that gift or incentive would affect the weight or credibility your readers give to your recommendation. If it could, then it should be disclosed. For example, being entered into a sweepstakes or a contest for a chance to win a thousand dollars in exchange for an endorsement could very well affect how people view that endorsement. Determining whether a small gift would affect the weight or credibility of an endorsement could be difficult. It’s always safer to disclose that information.
Also, even if getting one free item that’s not very valuable doesn’t affect your credibility, continually getting free stuff from an advertiser or multiple advertisers could suggest you expect future benefits from positive reviews. If a blogger or other endorser has a relationship with a marketer or a network that sends freebies in the hope of positive reviews, it’s best to let readers know about the free stuff.
Even an incentive with no financial value might affect the credibility of an endorsement and would need to be disclosed. The Guides give the example of a restaurant patron being offered the opportunity to appear in television advertising before giving his opinion about a product. Because the chance to appear in a TV ad could sway what someone says, that incentive should be disclosed.
