Key Features
- Timeliness SLAService Level Agreement - a guaranteed commitment with compensation if missed: If we ever miss an update or a test deadline, we'll credit you $500 off your next invoice.
- Strategic Experiment Design: We pinpoint high-impact test opportunities, create clear hypotheses, and design A/B or multivariateA/B testing compares two versions; multivariate tests multiple variations at once experiments to uncover what genuinely drives conversions.The wrong A/B test wastes 2–4 weeks and tells you nothing. The right test isolates a specific user-decision moment (button copy, form field order, image vs no-image) so the result is actually attributable to the one variable you changed. Good experiment design is what separates “we ran a test” from “we learned something.”The wrong A/B test wastes 2–4 weeks and tells you nothing.

T3/T4: When to upgrade to VWO Enterprise Show less
At Tier 3 (300K–600K visitors, 5–6 tests) and above, we strongly recommend upgrading to VWO Enterprise for advanced targeting, server-side testing, session recordings, and heatmaps. VWO Pro may introduce performance constraints at these traffic levels. Pricing is custom-quoted by VWO — we'll help you evaluate during onboarding.
