5 Best Split‑Testing Tools for WordPress (2025 Edition)

The quick guide for busy marketers & agencies

Whether you’re polishing a product‑launch page or squeezing extra revenue from an established store, the fastest way to get reliable answers is to send two versions into the wild and let real visitors vote with their clicks, scrolls, and wallets. A/B (or split) testing removes the guesswork and gives you hard data – no arguments, no “HIPPO” opinions, just evidence you can act on.

Below are the five WordPress options we see most often in 2025. We’ve put AB Split Test first because – well, you’re on absplittest.com and it really is the one we built to solve the headaches the others kept giving us. The remaining four are solid, but if you’re looking for the simplest path to trustworthy data, start with #1.

1. AB Split Test – The privacy‑first, page‑builder‑native choice

If you spend your day inside Blocks, Elementor, Bricks, Beaver Builder, or WooCommerce, AB Split Test feels like a natural extension of the editor. Spin up a test, pick a goal, and let our Bayesian engine do the heavy lifting. No external dashboards, no third‑party cookies, and nothing that will enrage your Key Vitals highlights:

  • Own your data – Everything runs in your WP install; nothing leaves your server
  • GDPR‑friendly by design – Local cookies only, so you can usually skip the consent banner
  • AI‑powered CRO assistant – Get a full page analysis, or click any element in “Magic Test” mode and get persona‑aware rewrites on the spot
  • Server‑side WooCommerce tracking – Catch every upsell or post‑purchase offer without hacks.
  • The most goals/ conversions
  • Multivariate testing
  • Revenue optimization – dont just optimize for clicks, but for revenue – integrated with Woo, SureCart, EDD, MemberPress and more

If you want results without the six‑figure price tag of an enterprise suite, start here. AB Split Test

2. Nelio A/B Testing – Feature‑packed and flexible

Nelio gives you the kitchen sink: multivariate tests, split‑URL tests, heat‑maps, menu and theme experiments, plus WooCommerce product testing. If you love dashboards and need to experiment with literally everything on a site, Nelio’s SaaS interface is robust—though you’ll pay a monthly fee for higher traffic tiers.

3. Split Hero – Clean UI for quick page or template tests

Split Hero markets itself as the “no‑code” A/B tool. You choose up to four page versions, set a goal such as form submissions or sales, and hit go. Reporting is visual and beginner‑friendly, making it a good pick for agencies managing lots of brochure sites – just don’t expect granular element testing, advanced conversion options, or advanced stats.

4. Thrive Optimize – Best if you already live in Thrive Suite

Thrive Optimize bolts onto Thrive Architect and lets you clone a page, tweak the variant, and measure conversions. It’s smooth inside that ecosystem, but outside of Thrive Suite it offers limited integration and requires the full $299/year bundle. Great for solopreneurs who already use Thrive’s landing‑page builder, less compelling for everyone else. Thrive Themes

5. VWO for WordPress – Enterprise muscle, enterprise price

VWO’s WordPress plugin simply injects the VWO tracking code so you can run tests from the VWO cloud platform. You’ll get powerful segmentation, heat‑maps, and personalization – but all managed off‑site, with a learning curve and pricing model meant for larger teams. If budgets are tight or data residency is a concern, investigate carefully. Website

Choosing the right tool

  • Need element‑level tests inside your favourite page builder? Pick AB Split Test.
  • Running complex multivariate experiments and want heat‑maps baked in? Nelio or VWO.
  • Client sites with simple headline/button tests? Split Hero or Thrive Optimize.

No matter which plugin you choose, commit to a habit of continuous testing. One winning variant per month can compound into serious revenue growth by year‑end.
