How it works
Four steps. One simple workflow.
Most A/B testing tools assume you have a growth team. SplitPea assumes you have an hour and a question. Here's the whole loop.
01
Install
Paste one snippet into Code Injection.
In your Squarespace dashboard, open Website → Pages → Custom Code → Code Injection and paste our snippet into the Header field (view our video below for a step-by-step). Afterwards, you're done. No app, no theme edits, no per-page Code Blocks.
02
Compose
Write a hypothesis. Draft a variant.
Pick a section of your Squarespace page in the SplitPea editor and rewrite the headline, swap a button, or change a photo. Save it as variant B. Variant A stays as it is.
03
Run
Half see A. Half see B. Real visitors.
SplitPea splits traffic 50/50 and quietly watches what each group does. No flicker. The page renders exactly like Squarespace renders it, just with your variant swapped in.
04
Decide
Get a verdict, in plain English.
When there's enough data to be confident, SplitPea tells you which one won, by how much, and how sure it is. Ship the winner with one click, or keep going if you want more certainty.

What you can test
The things you'd already change on a hunch.
These are the experiments Squarespace site owners actually run on SplitPea. Nothing exotic. Nothing that needs a developer. Just the swaps you've been meaning to try.
Hero copy
Try two versions of your homepage headline.
Most Squarespace homepages get rewritten once a quarter on a hunch. Test the next rewrite first. Two headlines, same photo, see which one keeps people scrolling.
Pricing page
Reorder the plans. Watch what happens.
Order matters. Highlighted plans matter. Test which arrangement actually makes people pick the plan you want them to pick on your services or pricing page.
CTAs and forms
"Book a call" or "See if we're a fit"?
Hire-me pages and contact pages live and die by the button copy. Run two versions for a week and let the data settle the argument.
Hero imagery
Storefront, or product close-up?
You probably have ten good hero photos and a strong opinion about which one. Your visitors might disagree. Cheap test, real answer.

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.
