Personizely is an A/B testing and experimentation platform for businesses that want to optimize their websites based on real data. Run A/B tests and multivariate experiments on any page, from headlines and layouts to pricing and full-page redesigns, target variations to specific visitor segments, and analyze results to see what drives conversions. Beyond testing, Personizely includes website personalization and on-site widgets (popups) for use cases like list building, promotions, and surveys, so teams can deploy winning variations and tailored experiences to the right visitors. It works on any website via a custom script, with dedicated integrations for Shopify, other ecommerce platforms, major website builders, and marketing tools.
