Frequently Asked Questions

Common questions about Nelio A/B Testing – AB Tests and Heatmaps for Better Conversion Optimization

Yes. You can create WooCommerce product experiments to compare alternative product information, including titles, descriptions, images, and prices. Use conversion goals to measure the results. If your store uses subscriptions or other complex pricing extensions, check compatibility with your specific setup before relying on experiments for recurring charges.

Nelio is designed to work with popular WordPress caching solutions. However, caching, script optimization, and CDN settings differ between sites and may require adjustments. Test your configuration, especially if you cache full pages or combine and delay JavaScript.

Most experiment processing and reporting takes place on Nelio's cloud services. As with any testing tool that loads alternative content and tracks visitor activity, actual performance depends on your site's configuration, caching, and the experiments you run.

Yes. Nelio A/B Testing supports the WordPress block editor (Gutenberg), Elementor, and other popular page-building workflows.

You can create multiple tests, but the free plan includes up to 500 tested page views per month, shared across your experiments. For sites with higher traffic or more simultaneous experiments, consider a premium plan.

Your available monthly testing quota is limited to 500 tested page views. To continue testing beyond the included quota, review the premium plans. For details of how quota is counted, see What is a tested page view?.

No. Nelio A/B Testing includes its own experiment results and conversion reports. Google Analytics integration is available when you also want to track relevant activity in your analytics setup.

Nelio A/B Testing does not store sensitive or personal visitor data as part of experiment tracking. The plugin does communicate with Nelio’s cloud services to provide its functionality, and usage and activity information may be collected as described in our Privacy Policy.

We release new features and bug fixes regularly. If you have specific needs or feature requests, we’d love to hear from you.
