# Analytics & Tracking Pixels

> Add Google Analytics, Facebook Pixel, and custom tracking scripts to your store

## Overview

Knot supports multiple tracking and analytics solutions to help you understand your store's performance and customer behavior. You can easily integrate Google Analytics, Facebook Pixel, and custom tracking scripts.

## Supported Pixel Types

### Google Analytics

Track visitor behavior, conversion rates, and e-commerce performance with Google Analytics.

**To add Google Analytics:**

1. Navigate to **Project Settings** � **Integrations**
2. Find the **Google Analytics** section
3. Enter your Measurement ID (e.g., `G-XXXXXXXXXX`)
4. Click **Save**

**To remove:** Leave the field empty and save.

### Facebook Pixel

Track conversions, optimize ads, and build targeted audiences for your Facebook campaigns.

**To add Facebook Pixel:**

1. Navigate to **Project Settings** � **Integrations**
2. Find the **Facebook Pixel** section
3. Enter your Pixel ID (e.g., `XXXXXXXXXXXXXXX`)
4. Click **Save**

**To remove:** Leave the field empty and save.

### Custom Pixels

Add any third-party tracking script or analytics tool not covered by the built-in integrations.

**To add Custom Pixels:**

1. Navigate to **Project Settings** � **Integrations**
2. Click **Add Custom Pixel**
3. Enter a name for your pixel (e.g., "TikTok Pixel", "Hotjar", "Klaviyo")
4. Paste your tracking script in the code field
5. Click **Save**

<Info>
  **No limitations**: You can add as many custom pixels as needed for your tracking requirements.
</Info>

**To remove:** Click the delete button next to the custom pixel, then save.

## How It Works

When you save your pixel configurations:

* The tracking scripts are automatically injected into your store
* Changes take effect immediately on your live site
* All pixels are loaded asynchronously to maintain site performance

## Best Practices

<Tip>
  **Pixel Setup Tips:**

  * Test your pixels using browser developer tools or pixel helper extensions
  * Add pixels one at a time to ensure each works correctly
  * Use custom pixels for any tracking service not directly supported
</Tip>

## Common Custom Pixel Examples

### TikTok Pixel

```javascript theme={null}
<script>
!function (w, d, t) {
  w.TiktokAnalyticsObject=t;var ttq=w[t]=w[t]||[];ttq.methods=["page","track","identify","instances","debug","on","off","once","ready","alias","group","enableCookie","disableCookie"],ttq.setAndDefer=function(t,e){t[e]=function(){t.push([e].concat(Array.prototype.slice.call(arguments,0)))}};for(var i=0;i<ttq.methods.length;i++)ttq.setAndDefer(ttq,ttq.methods[i]);ttq.instance=function(t){for(var e=ttq._i[t]||[],n=0;n<ttq.methods.length;n++)ttq.setAndDefer(e,ttq.methods[n]);return e},ttq.load=function(e,n){var i="https://analytics.tiktok.com/i18n/pixel/events.js";ttq._i=ttq._i||{},ttq._i[e]=[],ttq._i[e]._u=i,ttq._t=ttq._t||{},ttq._t[e]=+new Date,ttq._o=ttq._o||{},ttq._o[e]=n||{};var o=document.createElement("script");o.type="text/javascript",o.async=!0,o.src=i+"?sdkid="+e+"&lib="+t;var a=document.getElementsByTagName("script")[0];a.parentNode.insertBefore(o,a)};
  ttq.load('YOUR_PIXEL_ID');
  ttq.page();
}(window, document, 'ttq');
</script>
```

### Hotjar

```javascript theme={null}
<script>
(function(h,o,t,j,a,r){
    h.hj=h.hj||function(){(h.hj.q=h.hj.q||[]).push(arguments)};
    h._hjSettings={hjid:YOUR_SITE_ID,hjsv:6};
    a=o.getElementsByTagName('head')[0];
    r=o.createElement('script');r.async=1;
    r.src=t+h._hjSettings.hjid+j+h._hjSettings.hjsv;
    a.appendChild(r);
})(window,document,'https://static.hotjar.com/c/hotjar-','.js?sv=');
</script>
```

## Privacy Considerations

<Warning>
  **Important**: Ensure you comply with privacy regulations (GDPR, CCPA) when implementing tracking pixels. Update your privacy policy to reflect the tracking tools you use.
</Warning>

## Troubleshooting

**Pixel not firing?**

* Check that your pixel ID is correct
* Verify the script is properly formatted
* Use browser developer tools to check for console errors
* Test with pixel helper browser extensions

**Performance issues?**

* Review the number of pixels you've added
* Consider consolidating tracking through a tag manager
* Check that custom scripts are optimized
