A click earned through a misunderstood price or commitment is a poor measure of marketing quality. The problem may surface later in a support question, a cancellation or the realisation that the offer meant something different. Conversion improvement should therefore ask what customers understood, as well as what they did. This article explains how to recognise dark patterns, distinguish persuasion from manipulation and prioritise corrections. A clear offer should stand up to an informed decision, including a decision not to buy.
Recognize deceptive friction
False urgency, hidden fees, preselected extras and deliberately difficult cancellation are warning signs. The European Commission describes dark patterns as interfaces that trick users into choices they would not otherwise consider [1].
Distinguish persuasion from taking away a meaningful choice
A clear explanation of benefits, a relevant recommendation and a genuine offer deadline can help a customer decide. The problem begins when important information is hidden, refusal is deliberately difficult or the message creates a misleading impression. A useful editorial question is: would this person make the same decision if the total cost, commitment period and available options were visible immediately?
Consider an illustrative subscription example. Comparing plans clearly and explaining who each plan suits is a reasonable objective. Emphasising only a monthly amount while hiding an annual commitment in an inconspicuous note is a poor solution. Instead, show the billing period, total commitment and cancellation route alongside the price. This supports selling while reducing the potential for misunderstanding.
Make privacy choices meaningful
The EDPB identifies overloading, obstructing and hiding information among deceptive design patterns [2]. Audit consent wording, settings and the ability to decline optional processing. Clarity matters more than the number of buttons.
Apply the right legal framework
The DSA includes obligations relevant to online platforms; consumer protection and data protection rules can apply in other contexts. Do not assume that every DSA obligation automatically covers every ordinary business website [1][3].
Audit pricing and subscriptions
A 2026 European Commission sweep identified problems with discount references and optional basket additions [4]. Show total price, recurring charges and cancellation conditions before final confirmation.
Review the whole customer journey, not just the button
Walk through the website as a new visitor, including on a phone. Record what the customer sees before deciding and what appears only after a click. Pay particular attention to basket extras, plan duration, newsletter enrolment, closing pop-ups and the cancellation journey. Do not assume that a process is clear simply because your team knows it by heart.
For each finding, save a screenshot and describe the specific obstacle: for example, “the total is not visible before confirmation” or “the button does not explain that charging begins”. Add a proposed correction, an owner and a verification method. This turns a vague discussion about aggressive design into a task somebody can actually complete.
An A/B test does not justify a misleading variant
Test two clear and fair alternatives: the order of explanations, a benefit summary, a button label that accurately describes the action or the arrangement of a comparison. Do not use hidden charges or fabricated scarcity as a control. A higher click-through rate alone does not show that visitors understood the offer and deliberately chose it.
Alongside completed purchases, review cancellations, refunds and questions that reveal confusion. Read support feedback: “I did not know it would renew” is a more meaningful warning than a change in click rate. Compare sufficiently similar periods and record other changes that could affect the result. Do not infer an overall level of customer trust from a single short campaign.
What to fix first
Prioritise steps where customers accept a cost or commitment: prices, extras, renewals and cancellation. Next review consent choices and repeated prompts, then smaller inconsistencies in wording. After each change, repeat the journey and check that confirmation screens and emails match what the page promised. This is a practical customer-experience review, not a certification of any particular website’s legal compliance.
Frequently asked questions
Is every persuasive CTA a dark pattern?
No. Persuasion becomes problematic when it misleads or obstructs informed choice.
Does the DSA apply to every webshop?
Not automatically; applicability depends on the service and rule.
Can we ask for newsletter consent?
Yes, subject to the appropriate legal requirements and a clear choice.
What should we fix first?
Hidden charges, preselected extras and difficult cancellation.
What should we measure?
Complaints, refunds, retention and meaningful conversions.
