HTML / any site
Splitlab works on any website where you can add code to the page <head> — hand-coded HTML,
a static-site generator, or a CMS with a "custom head code" / "custom HTML" field.
Steps
- Copy your snippet from the dashboard → Install / SmartCode (it already has your project key), or grab the template from The install snippet.
- Paste it into the
<head>section of your website — on every page you want to run experiments on. - Publish your site, then verify the install.
Place it high in the head
Put the snippet as near the top of <head> as you can. The anti-flicker script needs to run
before your content paints, so the page never flashes the original before a variant applies.
