How do I install a visitor ID tag on SvelteKit?
On SvelteKit, your visitor identification tag goes in: src/app.html <script> tag (with optional nonce='%sveltekit.nonce%' for CSP) OR component <script> tag with module context. The install itself takes minutes; the part that goes wrong on SvelteKit is below.
Where the tag goes
- src/app.html <script> tag (with optional nonce='%sveltekit.nonce%' for CSP) OR component <script> tag with module context.
- 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 SvelteKit?
Multiple instance-level <script> tags can cause errors; wrap in 'if browser' check to avoid server-side execution.
How do you verify the tag fires?
npm run dev, open http://localhost:5173, check page source and DevTools for script execution.
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.
