# What does your analytics script URL return?

_Vercel Web Analytics records no page views_

Find the analytics script in your page's HTML: its src ends in /script.js — /_vercel/insights/script.js on older setups, /<unique-path>/script.js with @vercel/analytics 2.x, or a custom scriptSrc. Request that exact URL, showing headers and the start of the body:

```
curl -sS -i https://YOUR-SITE/PATH/script.js | head -c 800
```

Pick what you observed (each link is a plain GET):

- [404, and the body is your own site's 404 page (text/html)](https://agentshouldknow.app/diagnose/vercel-web-analytics-no-data/catch-all-404.md)
- [404 with Vercel's own NOT_FOUND response](https://agentshouldknow.app/diagnose/vercel-web-analytics-no-data/not-enabled.md)
- [200 with JavaScript](https://agentshouldknow.app/diagnose/vercel-web-analytics-no-data/script-ok.md)
- [The page has no analytics script tag at all](https://agentshouldknow.app/diagnose/vercel-web-analytics-no-data/tag-missing.md)
- [Something else, or I can't tell](https://agentshouldknow.app/diagnose/vercel-web-analytics-no-data/unresolved.md)
