Where the tag goes
- <script> tag in .astro component template OR is:inline directive for inline script injection.

Scripts are bundled by default and become render-blocking; use is:inline directive to prevent bundling if you need third-party code to execute immediately.
How do you verify the tag fires?
npm run build && npm run preview, open browser DevTools and check page source for script tags.
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.
