Treat wording, placement and timing experiments as disclosure changes that need review. Includes a free implementation worksheet.
Short answer
Treat wording, placement and timing experiments as disclosure changes that need review. Measure usability without making identity information unavailable to a test group.

When to use this guide
A conversion experiment removes the AI label for one cohort to reduce visual clutter near the input.
This is a fictional implementation scenario. The procedure below is Article 50 Hub's suggested working method, not a prescribed legal form, a customer result or a claim that every step is an additional statutory requirement.
Review procedure
-
List the exact interface differences and which users receive each variant.
-
Review whether each variant preserves accurate and timely identity information.
-
Test variant assignment, fallback and experiment shutdown behavior.
-
Record the approved variants and interpret engagement separately from notice adequacy.
What the example review finds
-
One cohort has no visible identity statement.
-
The experiment's fallback uses an unreviewed version.
Keep these example observations separate from your own results. An unknown or untested state should stay open until the relevant evidence has been inspected.

Review evidence
Use the downloadable blank worksheet linked on this page to connect the observed behavior with the deployed system. Add a reviewer, date, evidence reference, unresolved questions and a next action. The worksheet is editable locally and does not upload your records to Article 50 Hub.
Completion and handoff
Close the task only for the scope actually reviewed. Preserve the result that another authorized reviewer can reproduce, identify the owner of remaining work, and record a retest when the implementation changes. A completed worksheet is not a substitute for the underlying evidence.
Decision boundary
A higher conversion rate does not establish that a notice is adequate or that an omission is permissible.
The official references below provide legal or technical context. Resolve applicability and exception questions with the responsible qualified reviewer; use the product's tools to organize implementation work within that assessment.
