Direct User Involvement
A Fakedoor Test is a validation technique where a non-functional feature (the "fakedoor") is introduced to gauge user interest. By tracking clicks, interactions, or feedback, businesses can test demand without fully building the feature. Fakedoor Tests are valuable in product development, lean startups, and innovation projects, where they help in prioritizing features, reducing development risks, and ensuring that efforts are focused on what users truly want or need.
7 steps to complete
Determine the specific feature or product you are looking to test and what its value proposition is. Form a clear hypothesis about the potential demand, usability, or functionality of the product or feature.
Create a simple, realistic representation of the proposed feature or product. This could be a button, link, or banner that appears to be functional but does not actually lead to a fully-developed feature or product. The design should be convincing enough for users to believe it is real and should entice them to interact with it.
Incorporate the fakedoor into the appropriate location, such as your website or app. Ensure that it is seamlessly integrated into the user flow and does not disrupt the overall user experience or create friction.
Track user interactions with the fakedoor using analytics tools, such as click-through rates and hover states. Observation of users interacting with the fakedoor can also be valuable for collecting qualitative data.
When users interact with the fakedoor, present them with a message, survey, or form explaining that the feature or product is in development and that their feedback is valuable. Collect user input regarding their expectations and desires for the tested feature or product.
Evaluate the quantitative and qualitative data gathered from user interactions and feedback. Determine if the hypothesis was validated or if user responses indicate a different direction should be taken in the feature or product development.
Based on the results and insights gathered, adjust your hypothesis, feature design, and fakedoor as necessary. Repeat the fakedoor test process until you achieve desired results and are confident in moving forward with full development.
See how this method is applied in practice
Research conducted with Groupon users to understand how they discover and evaluate local deals. Participants included frequent buyers in the Food & Drink and Health & Beauty categories, as well as occasional users. The study revealed that users rely heavily on personalized recommendations and location-based filtering, with visual imagery and merchant ratings being key decision factors. Users also expressed interest in occasion-based browsing like "date night deals" or "weekend activities."
Study with restaurant, spa, and fitness business owners to understand their experience with Groupon's merchant platform. Participants included both new merchants in onboarding and experienced merchants running multiple campaigns. Findings showed merchants struggled with understanding optimal pricing strategies, setting deal capacity, and interpreting performance analytics. Many requested competitive benchmarking and seasonal promotion guidance.
Research with Groupon customers who recently redeemed deals at local businesses. The study focused on the in-person redemption experience, including showing vouchers to merchants, handling booking requirements, and resolving issues. Insights revealed that users felt anxious about merchant acceptance and wanted clearer communication about what to expect during redemption.
What you'll produce from this method
Clearly defined objectives for the Fakedoor Test, outlining the goals and purpose of the study and what the team expects to learn from the test.
Description of the ideal participants for the study, including demographics, characteristics, and behaviors that represent the user base for the product.
Creation of realistic use-case scenarios for the test, including specific tasks or actions the user would typically perform in order to interact with the fakedoor elements.
Designs and mock-ups of the fakedoor elements (e.g., buttons, calls to action, links) that will be inserted into the product, simulating the future features or functionality being tested.
Detailed outline of the steps and procedures to be followed during the test, including instructions for moderators, interactions with participants, and sequencing of tasks or scenarios.
Methods and tools to be used for collecting and recording data during the study, such as user interaction data, click rates, time on task, satisfaction ratings, and any qualitative feedback.
A short survey to gather baseline information from participants before the test, including demographics, prior experience with the product, and any relevant attitudes or beliefs.
A survey to collect user feedback after the test, including questions related to user satisfaction, ease of use, perceived usefulness of the fakedoor feature, and any suggestions for improvement.
A comprehensive report detailing the findings from the Fakedoor Test, including data analysis, key takeaways, user feedback, and recommendations for product improvements based on the results.
A summary of the actionable insights gained from the test, including suggested design changes, feature edits, and a prioritized list of product updates to be made based on user feedback and observed behaviors.
