Updated December 2026
10 min read
TL;DR

For landing page testing: Use ExperimentHQ for any landing page platform (WordPress, Webflow, custom). Use Unbounce or Instapage if you're already using their builders. Key features needed: visual editor, quick setup, and conversion tracking. Avoid enterprise tools—they're overkill for LP optimization.

Who this is for

  • Marketers running paid campaigns
  • Growth teams optimizing conversion funnels
  • Agencies managing client landing pages

Who this is NOT for

  • Full website optimization (see general guide)
  • In-app experiments (use server-side tools)

Our Recommendation

For most landing pages: Use ExperimentHQ. Visual editor, $29/month, works with any platform.

Using Unbounce/Instapage: Use their built-in A/B testing—it's already included.

Avoid: Enterprise tools like VWO or Optimizely for simple LP testing. They're expensive overkill.

FAQ

How much traffic do I need to test landing pages?
For meaningful results, aim for 1,000+ visitors per variant. With paid traffic, this is usually achievable in 1-2 weeks. Test bigger changes (headlines, layouts) rather than small tweaks to get faster results.
Should I test the entire page or individual elements?
Start with entire page variations (radically different approaches). Once you find a winning direction, test individual elements. Testing small elements first often leads to local maxima.
