How do I install a visitor ID tag on Webflow?
On Webflow, your visitor identification tag goes in: Project Settings > Custom Code tab > Add scripts (for head/footer) or API registration. Note the plan gate: Starter plan and above (Free plan not supported for custom code via UI). The install itself takes minutes; the part that goes wrong on Webflow is below.
Where the tag goes
- Project Settings > Custom Code tab > Add scripts (for head/footer) or API registration.
- Plan requirement: Starter plan and above (Free plan not supported for custom code via UI)
- Paste your vendor’s tag snippet exactly as issued. Do not wrap it in extra script tags or reformat it.
- Publish or deploy, then verify (below) before trusting data.
What breaks visitor tracking on Webflow?
Custom code is not visible in the canvas editor preview; must publish site to test execution.
How do you verify the tag fires?
Publish site and open live page in new browser window, check DevTools console for script output.
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.
