A/B Testing on Squarespace. See what happens.

Squarespace makes it easy to build a good-looking website. It does not make it easy to test one. We help you stop guessing and start growing with evidence-led experiments.

What Squarespace gives you

Page views, traffic sources, form submissions, sales if you're on the Commerce plan. That's enough to understand what's happening, but analytics doesn't tell you what would happen if you changed something.

Will this slow down my site?

SplitPea's snippet is under 8KB, loads asynchronously, and does not block your Squarespace page from rendering.

Do I have enough traffic?

If you get around 1,000 visits a month, you can often get useful results in two to four weeks.

Do I need to edit my Squarespace template?

No. Add the snippet once through Code Injection, then create variations in SplitPea.

What should I test first?

Start with visible decisions: the hero headline, booking button, form length, product framing, or social proof.
