Frequently asked questions

How is this different from Google Optimize?

Google Optimize shut down in 2023. Most alternatives (VWO, Optimizely) cost $200-1000+/month. A/B Split Tester gives you headline and CTA testing with AI-suggested variants and statistical significance for a fraction of the price.

How do AI-suggested variants work?

Select an element to test and click 'Suggest Variants'. Claude AI analyses your page context and generates 3 alternative options, each taking a different copywriting angle. Pick one or use it as inspiration for your own variant.

Does it affect page load speed?

The client-side script is approximately 3KB minified with no dependencies. Variant swapping happens instantly on page load.

How does it determine a winner?

Chi-squared statistical test at 95% confidence level. The plugin requires a minimum of 100 impressions per variant and declares a winner only when the data is statistically significant.

Stop guessing. Start testing.
