VWO

VWO is an all-in-one A/B testing and conversion optimization platform that combines experimentation, heatmaps, session recordings, surveys, and personalization in a single tool — built for growing businesses and CRO teams.

What is VWO?

VWO (Visual Website Optimizer) is an all-in-one A/B testing and conversion optimization platform that brings the entire CRO process into a single tool — planning, tracking, testing, analyzing, and targeting. It combines A/B testing, multivariate testing, split URL testing, heatmaps, session recordings, visitor surveys, and personalization in one place, which means most teams can replace a stack of point tools (like Hotjar + a testing tool) with VWO alone. TrustRadius reviewers score it 8.4 out of 10 across 199 reviews, with consistent praise for the intuitive WYSIWYG visual editor, unlimited experiments on paid plans, SmartStats Bayesian reporting, and support that reviewers describe as best-in-industry. Since Google Optimize was sunset, VWO has cemented itself as a leading option, offering a free Starter plan up to 50K MTU. The main drawbacks are pricing — which scales with monthly tracked users and stacks across separately-priced modules — and the fact that advanced features like multivariate testing and full personalization sit behind Pro and Enterprise tiers. Historically there have been flickering and tracking-allocation bugs, though reviewers say support usually handles issues well. In January 2026 VWO merged with AB Tasty under an Everstone-backed company, so the long-term roadmap is being decided. For growing businesses and CRO agencies that want one approachable tool that covers the full experimentation workflow, VWO is a strong, well-balanced choice — cheaper than Optimizely, friendlier than Adobe Target, and more complete than point solutions like Convert.

Key Features

• A/B Testing — Compare page versions with unlimited concurrent experiments
• Multivariate Testing — Test multiple changes at once for deeper insights
• Split URL Testing — Run experiments across different URLs and landing pages
• Visual Editor — Drag-and-drop page changes with no coding required
• Heatmaps — See how users interact with your site (click, scroll, move)

Who is it for?

• Growing ecommerce and SaaS businesses running constant website experiments
• CRO teams and agencies that need testing, research, and personalization in one tool
• Non-technical marketers using the WYSIWYG editor to run simple tests
• Former Google Optimize users who need a capable, approachable replacement
• Teams that value responsive, CRO-savvy customer support

Who is it NOT for?

• Ultra-enterprise teams needing complex server-side or full stack experimentation at scale (use Optimizely)
• Budget-constrained mid-market teams — the MTU pricing and feature-gating push costs up fast (Convert is cheaper)
• Small sites wanting a basic free A/B tool can use the Starter plan, but will outgrow it quickly
• Anyone wary of the VWO/AB Tasty merger and an uncertain roadmap in 2026
