Clear PostHog Experiment naming helps your team quickly understand each test’s purpose, scope, and context—without digging into the details. We use the following guidelines to create consistent and meaningful experiment names.

Experiment Naming Structure
We use this general format:
[Experiment number] – [Step of the Funnel/Page] – [Test Hypothesis]
Experiment number: Use a sequential number to keep track of experiments easily (e.g., 001, 002, 003).
Step of the Funnel/Page: Identify where in the user journey the experiment is running (e.g., Homepage, Signup, Checkout, Onboarding).
Test Hypothesis: Describe what’s being tested in a few words (e.g., CTA Text, Modal Design, Pricing Layout).
Feature Flag Naming Structure
We use something very similar to the Experiment name, with a few changes—like converting the step of the funnel/page into a number or abbreviation, removing spaces, and keeping everything lowercase for easier implementation in code.
Examples
Experiment Names:
010 – Pricing Page – Toggle Design
015 – Onboarding – Welcome Modal
Feature Flags:
010- pricing-page-toggle-design
015-onboarding-welcome-modal
Note: We use 3-digit numbers to ensure we won’t run out of unique test identifiers in the future.
Best Practices
- Be specific: Avoid vague names like “Test 1” or “Homepage Experiment.” They’re hard to track later.
- Keep it short but descriptive: Aim for clarity without over-explaining.
- Use consistent terms: Align naming across experiments.
