# Pixel is installed but not tracking

> Fix issues where the pixel is on your site but stats show zero.

If you see zero impressions even though the pixel is installed, check these:

## 1. Verify the pixel key

Open your page source and find the TinyBell pixel code. Compare the `pixel_key` value with the one shown in your TinyBell dashboard under **Campaigns > Pixel Code**. They must match exactly.

## 2. Check for JavaScript errors

Open your browser's Developer Tools (F12 or right-click > Inspect > Console). Look for any red error messages related to TinyBell or your website. JavaScript errors on your page can prevent the pixel from executing.

## 3. Check ad blockers

Some ad blockers may block the TinyBell pixel. Disable your ad blocker and reload the page. If the notification appears, the ad blocker is the cause.

## 4. Cache issues

Your browser or CDN may be serving a cached version of the page without the pixel. Clear your browser cache and any server-side cache (Cloudflare, Varnish, etc.).

## 5. HTTPS

The TinyBell pixel requires HTTPS. If your website uses HTTP, the pixel may be blocked by the browser. Upgrade your website to HTTPS.
