Experiment Scope
This playbook replaces an unverified “3x downloads” case. It does not claim that a specific client achieved a fixed lift. Its purpose is to show how an ASO engagement should separate observable inputs, platform experiments, external acquisition changes, and conclusions.
Primary evidence
Play Console acquisition and store-listing experiment data
Change policy
One testable variable per experiment whenever practical
Segmentation
Country, language, traffic source, and returning-user effects
Outcome boundary
No guaranteed ranking, conversion, or download increase
Freeze a Baseline Before Editing
Record the comparison window, countries, languages, acquisition sources, listing visitors, first-time installers, conversion rate, and material campaign changes. A before-and-after chart is not persuasive if paid traffic, featuring, seasonality, price, or app quality changed at the same time.
Write the hypothesis in advance
Use a falsifiable statement: “Showing the core workflow in screenshot one will improve first-time installer conversion for US English search traffic.” Define the metric, audience, variant, and stopping rule before the result is visible.
Respect Listing Constraints
The app title must stay within Google Play's current 30-character limit. A previous version of this page incorrectly described a 44-character title as valid. Short description and full description limits, prohibited metadata patterns, and asset requirements should be checked against current first-party documentation at the start of each engagement.
- Use the title for the brand and clearest category signal, not a chain of keywords.
- Make screenshot one communicate the primary outcome without relying on tiny text.
- Keep claims visible in assets consistent with actual app functionality.
- Localize the search proposition and creative, not only the words.
Production-ready copy gate
Run a Controlled Store Listing Experiment
- Select the highest-impact uncertainty: icon, screenshot sequence, feature graphic, or localized copy.
- Create a variant that changes the chosen variable without introducing unrelated claims.
- Use Google Play's store listing experiments where the asset and market are eligible.
- Keep campaigns and release behavior stable enough to interpret the result.
- Wait for a decision-quality sample; do not stop because an early line looks favorable.
- Record the result, uncertainty, segment differences, and next decision.
Decision Rules
| Observed result | Decision | What to record |
|---|---|---|
| Clear positive result | Apply the winning variant to the tested market | Audience, dates, metric, confidence range, and implementation date |
| Inconclusive | Keep the control or run a materially stronger variant | Why the sample or effect was insufficient |
| Negative result | Retain the control and document the failed hypothesis | Which message or asset underperformed and for whom |
| Conflicting segments | Use localized or custom listings when justified | Country, language, and traffic-source divergence |
