How do I install a visitor ID tag on Squarespace?

On Squarespace, your visitor identification tag goes in: Settings > Advanced > Code Injection (head/footer) OR Code Block element in page. Note the plan gate: Core, Plus, Advanced, or legacy plan (Code Blocks on all plans, but JS/iframes require paid tier). The install itself takes minutes; the part that goes wrong on Squarespace is below.

Where the tag goes

  1. Settings > Advanced > Code Injection (head/footer) OR Code Block element in page.
  2. Plan requirement: Core, Plus, Advanced, or legacy plan (Code Blocks on all plans, but JS/iframes require paid tier)
  3. Paste your vendor’s tag snippet exactly as issued. Do not wrap it in extra script tags or reformat it.
  4. Publish or deploy, then verify (below) before trusting data.

What breaks visitor tracking on Squarespace?

Squarespace does not provide support for custom code modifications; only Basic CSS/HTML is officially supported.

How do you verify the tag fires?

Inject test code and view page source (Ctrl+U) to confirm code appears in head/body.

Then run through the labeled QA checklist before you rely on the numbers, and set expectations with the match-rate calculator — no vendor identifies every visitor.
