Stop guessing. Start testing.
Run controlled A/B experiments on any element of your website. Let real user data tell you which variant converts better with statistical confidence.
Make every decision with data behind it
A/B testing lets you compare two versions of a page element to determine which performs better. You split your traffic between variants A and B and measure which one achieves your goal.
Unlike guesswork, A/B testing gives you statistically significant evidence. You know with confidence whether a change improves conversions, not just whether it looks better.
Spectry makes it easy to set up tests without engineering involvement. Define your variants, pick your goal metric, and Spectry handles traffic splitting, data collection, and significance calculation.
Controlled traffic splitting
Traffic is split evenly and randomly between variants, ensuring unbiased, reliable results you can act on.
Real-time results
Watch conversion rates and statistical significance update live as data flows in. No waiting for manual reports.
Automatic winner detection
Spectry alerts you when a result reaches statistical significance so you can confidently roll out the winning variant.
Test anything that matters to your conversions
Every element on your page is a hypothesis waiting to be tested. Spectry lets you experiment on the things that drive the biggest impact.
Headlines & Copy
Your headline is the first thing visitors read. Small wording changes can have outsized impact on engagement and sign-ups.
- Value proposition variations
- Benefit-led vs. feature-led copy
- Urgency and social proof messaging
CTAs & Buttons
Button text, color, size, and placement all influence click-through rates. Find the combination that drives the most action.
- Button text and microcopy
- Color and visual weight
- Placement and surrounding context
Layouts & Designs
Test different page structures, image placements, and content hierarchies to discover what layout guides users toward conversion.
- Hero section layouts
- Form placement and length
- Social proof positioning
Why run A/B tests with Spectry
Spectry combines A/B testing with session recordings and heatmaps, giving you the full picture of why a variant wins, not just that it does.
Increase conversion rates
Even small improvements compound over time. A 10% lift in sign-up rate from a headline test can mean thousands of extra customers per year.
- Optimize landing pages for more sign-ups
- Reduce checkout abandonment
- Improve trial-to-paid conversion
Eliminate guesswork
Design debates cost time. Replace opinion-driven decisions with data: variant B converts 18% better at 97% confidence.
- Replace opinion-driven decisions with data
- Build a culture of continuous experimentation
- Justify design decisions to stakeholders
Understand your users better
When combined with session recordings and heatmaps, A/B test results reveal not just what worked but why, closing the loop on user understanding.
- Pair test results with session recordings
- See heatmap differences between variants
- Understand behavioral patterns behind results
Compound growth over time
Each successful test raises your baseline. Regular testing creates a flywheel of compounding improvements that builds a significant conversion advantage.
- Stack wins with sequential tests
- Build an experiment backlog from insights
- Track cumulative improvement over time
