How do I install a visitor ID tag on Wix?

On Wix, your visitor identification tag goes in: Settings > Custom Code > + Add Custom Code (Development & integrations section). The install itself takes minutes; the part that goes wrong on Wix is below.

Where the tag goes

  1. Settings > Custom Code > + Add Custom Code (Development & integrations section).
  2. Paste your vendor’s tag snippet exactly as issued. Do not wrap it in extra script tags or reformat it.
  3. Publish or deploy, then verify (below) before trusting data.

What breaks visitor tracking on Wix?

Site must be published and have a connected domain before custom code can be added; Wix does not support custom code troubleshooting.

How do you verify the tag fires?

Visit published site, open DevTools console, and verify no errors; check Network tab for script loads.

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.
