What to compare

  • What page or element types can be tested.
  • How variants are created.
  • How conversions are defined and measured.
  • How traffic is split.
  • Whether testing fits your existing builder.

Where Thrive Optimize fits

Thrive positions Optimize as an A/B testing tool that works with Thrive Architect. That makes it a natural fit for sites already building landing pages in Architect.

When not to test

If traffic is too low for meaningful evidence, improve obvious usability and message problems first rather than treating every change as an experiment.
