Testimonials or endorsements
The label “Testimonials or endorsements” describes this recurring design mechanism: a named or attributed person's approval is used persuasively without sufficient authenticity, representativeness or relationship disclosure. It is a design and research taxonomy, not a standalone legal conclusion. Depending on the complete journey and likely effect, current EU consumer or sector rules may require separate assessment. No published Digital Fairness Act proposal currently creates a pattern-specific prohibition or duty under this label.

Definition
What is this pattern?
A named or attributed person's approval is used persuasively without sufficient authenticity, representativeness or relationship disclosure. The label describes a recurring design mechanism; whether a particular implementation is harmful or unlawful depends on the complete journey, audience, evidence and rules within scope.
How it works
A named or attributed person's approval is used persuasively without sufficient authenticity, representativeness or relationship disclosure. A recommendation gains apparent independence or expertise by withholding the speaker’s payment, employment or other material relationship.
Warning signs
- The interface attributes an evaluative statement or approval to a person or identifiable group.
- The statement is connected to a purchase or other material choice.
- Authenticity, material connection or representativeness is unsupported or contradicted by verified evidence.
Potential harms
- Viewers may give the recommendation weight they would not give a clearly identified advertisement.
- Buyers may mistake an internal promotional statement for independent evaluation.
Learn by comparison
What does this look like?
These fictional examples make the design mechanism easier to recognise. They do not depict a real company and do not establish that an individual interface is unlawful.
Illustrative example 1 · Social product landing page
A fictional creator calls a skincare product a personal favourite and links to purchase without disclosing payment until the bottom of a collapsed caption.
Potential consumer harm: Viewers may give the recommendation weight they would not give a clearly identified advertisement.
Illustrative example 2 · Software comparison page
A fictional software company publishes a five-star quote from its product manager under an “Independent experts recommend” heading.
Potential consumer harm: Buyers may mistake an internal promotional statement for independent evaluation.
Paid creator recommendation lacks disclosure
A fictional creator calls a skincare product a personal favourite and links to purchase without disclosing payment until the bottom of a collapsed caption.
My everyday favourite. The creator’s payment is hidden below the promotional claim.. Shop my pick. Claim basis, collapsed
Paid advertisement. The material relationship appears before the recommendation and link.. View advertised product. Claim basis, expanded: The relevant population, period, inventory or offer state is presented with the message.. View the source and period for “View advertised product”
Why the first version can mislead: The interface asks the user to rely on other people’s behaviour or approval. The cue “Shop my pick” has persuasive meaning only if its population, period, metric and relationship match the represented claim. The panel instead says: “The creator’s payment is hidden below the promotional claim.” Viewers may give the recommendation weight they would not give a clearly identified advertisement.
What a fairer design does: Disclose the material relationship at first exposure and keep it visible near the endorsement and purchase route.

Review questions (3)
- Which source record substantiates “Shop my pick”, including its population, period, metric and any commercial relationship?
- Record the claim, timestamp, data source and post-claim state; which evidence supports “The interface attributes an evaluative statement or approval to a person or identifiable group”?
- Can the claim be reproduced from a defined population and period, or does the evidence instead fit “Unaffiliated verifiable statement accurately quoted in context”?
Employee review presented as independent expertise
A fictional software company publishes a five-star quote from its product manager under an “Independent experts recommend” heading.
Independent expert verdict. The reviewer is an employee and the relationship is not disclosed.. Five stars. Read methodology
Product-team perspective. The speaker’s role and connection are visible beside the quote.. Read methodology. Five stars. Price, period and commitment, expanded: The price and material terms associated with “Read methodology” remain beside this choice.
Why the first version can mislead: The interface asks the user to rely on other people’s behaviour or approval. The cue “Five stars” has persuasive meaning only if its population, period, metric and relationship match the represented claim. The panel instead says: “The reviewer is an employee and the relationship is not disclosed.” Buyers may mistake an internal promotional statement for independent evaluation.
What a fairer design does: Identify the speaker and relationship accurately and substantiate any expertise or independence claim.

Review questions (3)
- Which source record substantiates “Five stars”, including its population, period, metric and any commercial relationship?
- Place the compared prices, billing periods and material terms on one evidence sheet; where does it support “The statement is connected to a purchase or other material choice”?
- Can the claim be reproduced from a defined population and period, or does the evidence instead fit “aggregate rating without testimonial attribution”?
What is a fairer alternative?
Use authentic, supportable testimonials and clearly disclose material commercial connections and limitations.
Legal and information status
Legal position at a glance
A named or attributed person's approval is used persuasively without sufficient authenticity, representativeness or relationship disclosure. A recommendation gains apparent independence or expertise by withholding the speaker’s payment, employment or other material relationship. Risk increases where the mechanism changes a material consumer choice, hides a consequence or makes a genuine alternative harder to use. The taxonomy label remains a review prompt and does not establish an infringement.
Dark-pattern research taxonomy
Editorial analysis
The cited research sources support identification and comparison of this recurring interface mechanism. They do not determine that a particular interface is unlawful.
UCPD Articles 5 to 9, where applicable
Possible risk indicator
Depending on the trader, audience, overall presentation, material information and likely transactional effect, the facts may require a separate assessment under the applicable UCPD provisions.
Evidence layers and open questions
Applicable law, enforcement records, policy preparation, stakeholder input, editorial analysis and unknown future details remain visibly distinct.
Current lawCurrent law
The UX label “Testimonials or endorsements” is not a standalone EU offence. Depending on the trader, audience, complete presentation, omitted information and likely transactional effect, the observed facts may require a separate assessment under the applicable UCPD provisions or another instrument within scope.
Under considerationUnder consideration
The Commission is preparing a Digital Fairness Act initiative, but the call for evidence does not select a final rule for testimonials or endorsements or establish that this taxonomy term will appear in a proposal.
Editorial analysisEditorial analysis
The pattern definition, variants and examples on this page use the cited research taxonomy sources to support recognition and comparison. That analytical classification is not a legal conclusion about an individual interface.
UnknownUnknown
No published DFA proposal currently establishes a definition, covered actor, legal threshold, duty, remedy, transition rule or application date for testimonials or endorsements. Those details remain unknown pending primary legislative text.
Context matters
Context and boundary cases
- The interface attributes an evaluative statement or approval to a person or identifiable group.
- The statement is connected to a purchase or other material choice.
- Authenticity, material connection or representativeness is unsupported or contradicted by verified evidence.
- Exclude or qualify the label where unaffiliated verifiable statement accurately quoted in context.
- Exclude or qualify the label where aggregate rating without testimonial attribution.
- Exclude or qualify the label where clearly labelled fictional illustration.
When a similar design can serve a legitimate purpose
- A similar design should not be classified this way where unaffiliated verifiable statement accurately quoted in context.
- A similar design should not be classified this way where aggregate rating without testimonial attribution.
- A similar design should not be classified this way where clearly labelled fictional illustration.
Operational review
What teams should review
- Teams
- Which source record substantiates “Shop my pick”, including its population, period, metric and any commercial relationship?
- Record the claim, timestamp, data source and post-claim state; which evidence supports “The interface attributes an evaluative statement or approval to a person or identifiable group”?
- Can the claim be reproduced from a defined population and period, or does the evidence instead fit “Unaffiliated verifiable statement accurately quoted in context”?
