Test Insights: See What Your Testing Program Has Learned
You've run hundreds of tests. But what have you actually learned? GrowthLayer's Test Insights surfaces the patterns hiding in your test history—so you can build on past wins and compound your knowledge.
Stop Guessing—Know Which Changes Actually Move the Needle
Tests Run in Isolation
Each experiment is analyzed individually. You never aggregate learnings to see the bigger picture.
No Pattern Recognition
CTA button tests win 40% of the time. Form simplification tests win 60%. But you'd never know without manual analysis.
Blind Spots Stay Blind
You've tested the checkout 50 times and the category page twice. But without gap analysis, you can't see it.
Insights Die in Presentations
Someone made a great slide deck about test learnings last year. Nobody can find it. Nobody remembers what it said.
Extract Learnings & Build on Past Wins
GrowthLayer analyzes your entire test library to surface patterns, gaps, and winning strategies—turning scattered experiments into compounding knowledge.
Win Rate Analysis
See which categories, page types, and test patterns have the highest success rates—backed by your own data.
AI-Powered Insights
Get automated recommendations based on your specific testing history—not generic best practices.
Gap Analysis
Identify underexplored areas of your site or app. Stop over-testing the same pages.
Experimentation Insights at a Glance
How Teams Use Test Insights
Program Health Checks
Pull aggregate win rates, test velocity, and pattern breakdowns for leadership in minutes—not days.
Data-Driven Prioritization
Use historical win rates by area to prioritize where your testing resources will have the most impact.
Pattern-Based Hypotheses
"Social proof tests win 55% on product pages." Use patterns to generate higher-probability test ideas.
See patterns across your entire test history
AI analyzes your experiments to surface which hypothesis types win most often, which page areas have the highest impact, and where to focus your next tests for maximum lift.
Even Better With
Test Insights works best when you have a rich test library. Here's how to build it.
Frequently Asked Questions
What are Test Insights?
Test Insights uses meta-analysis—the statistical technique of combining results from multiple A/B tests—to identify patterns and extract learnings. Instead of looking at each test in isolation, Test Insights helps you see trends across your entire experimentation program and build on what's working.
How many tests do I need for meaningful insights?
You can start seeing useful insights with as few as 20-30 tests. However, patterns become more statistically reliable as your library grows. Most teams see strong pattern detection value once they've logged 50+ experiments.
Can I analyze tests from different testing platforms?
Yes. GrowthLayer is platform-agnostic. Whether you run tests in Optimizely, VWO, Google Optimize, or any other tool, you can import results into GrowthLayer for unified insights. Your learnings aren't locked into one vendor.
How does AI-powered pattern detection work?
GrowthLayer uses natural language processing to understand test hypotheses and outcomes, then clusters similar experiments together. The AI identifies which types of changes consistently win, which areas are under-tested, and recommends high-potential test ideas based on your specific history—not generic best practices.
