Nelio Testing is a WordPress plugin that enables website owners to run A/B tests and multivariate experiments to optimize conversions and user engagement. The plugin allows testing different versions of pages, posts, custom post types, headlines, and widgets without requiring technical knowledge. Nelio Testing provides a visual editor for creating test variations, automatic traffic distribution, and statistical analysis to determine winning variants. It integrates seamlessly with WordPress and popular page builders, making it easy to test design changes, content variations, and call-to-action elements. The plugin includes features for heatmaps, conversion tracking, and goal-based optimization. Nelio Testing is designed for WordPress site owners, marketers, and agencies seeking to improve website performance through data-driven optimization without relying on external testing platforms.
Counts follow the sites we crawl. Our crawl grew sharply in October 2026, so part of that month's rise reflects coverage, not adoption.
