**You can manage adblockers with plausible-hugo by self-hosting the analytics script, enabling a fallback tracking pixel, or configuring Netlify redirects to proxy requests through your own domain.**

The `divinerites/plausible-hugo` theme provides built-in mechanisms to bypass aggressive ad-blocker filters that target the default Plausible.io CDN URL. By leveraging custom partial templates and site parameters, you can ensure analytics data collection remains reliable even when visitors use browser extensions like uBlock Origin or AdBlock Plus.

## Why Adblockers Target Plausible Analytics

Most ad-blockers maintain filter lists that block requests to `https://plausible.io/js/plausible.js` and similar analytics endpoints. When the script is blocked, the `plausible()` function never loads, and page views go unrecorded. The `plausible-hugo` theme counters this by allowing you to serve the script from your own infrastructure or use alternative tracking methods that evade pattern-based blocking.

## Method 1: Self-Host the Plausible Script

Self-hosting is the most reliable way to manage adblockers with plausible-hugo. When you serve [`plausible.js`](https://github.com/divinerites/plausible-hugo/blob/main/plausible.js) from your own domain (e.g., [`/js/plausible.js`](https://github.com/divinerites/plausible-hugo/blob/main//js/plausible.js)), ad-blockers cannot distinguish it from your site's other assets.

### Configuration

Set the `plausible_script_src` parameter in your [`config.toml`](https://github.com/divinerites/plausible-hugo/blob/main/config.toml) to point to a local path:

```toml
[params]
  plausible_script_src = "/js/plausible.js"

```

### Implementation Details

The [`layouts/partials/plausible_js.html`](https://github.com/divinerites/plausible-hugo/blob/main/layouts/partials/plausible_js.html) partial checks for `site.Params.plausible_script_src`. When present, it renders a `<script>` tag using your custom URL instead of the default `https://plausible.io/js/plausible.js`. Place the actual [`plausible.js`](https://github.com/divinerites/plausible-hugo/blob/main/plausible.js) file in your repository's `static/js/` directory so Hugo copies it to the output root during the build.

## Method 2: Enable the Fallback Tracking Pixel

When JavaScript is completely blocked, you can still collect minimal analytics using a 1×1 pixel image request. This fallback method sends page view data to Plausible's API endpoint via an `<img>` tag.

### Configuration

Enable the fallback in your site configuration:

```toml
[params]
  plausible_fallback = true

```

### How It Works

The [`layouts/partials/plausible_head.html`](https://github.com/divinerites/plausible-hugo/blob/main/layouts/partials/plausible_head.html) partial evaluates `site.Params.plausible_fallback`. When enabled, it injects an `<img>` element with `src="https://plausible.io/api/event?..."` containing the current page URL and referrer. Even if the main script is blocked by an ad-blocker, the browser still requests this image, allowing Plausible to record the visit.

## Method 3: Configure Content Security Policy Headers

Content Security Policy (CSP) headers can inadvertently block analytics scripts if not configured properly. The theme provides CSP helpers to ensure your policy permits the Plausible script source.

### Configuration

Set the CSP parameter to include your script source:

```toml
[params]
  plausible_csp = "script-src 'self' https://plausible.io"

```

### Implementation

The [`layouts/partials/plausible_csp.html`](https://github.com/divinerites/plausible-hugo/blob/main/layouts/partials/plausible_csp.html) and [`layouts/partials/plausible_head_csp.html`](https://github.com/divinerites/plausible-hugo/blob/main/layouts/partials/plausible_head_csp.html) partials generate CSP meta tags or header configurations. When using self-hosting, update `plausible_csp` to allow `'self'` only. If using the fallback pixel, ensure `img-src` directives permit `https://plausible.io`.

## Method 4: Use Netlify Redirects for Proxying

For sites deployed on Netlify, you can proxy Plausible requests through your own domain using redirect rules. This approach keeps the URL structure consistent ([`/js/plausible.js`](https://github.com/divinerites/plausible-hugo/blob/main//js/plausible.js)) while actually fetching from Plausible's CDN.

### Configuration

Enable the Netlify redirects partial:

```toml
[params]
  plausible_script_src = "/js/plausible.js"

```

Then include the Netlify-specific partial in your layout:

```html
{{ partial "plausible_redirects_netlify.html" . }}

```

### How It Works

The [`layouts/partials/plausible_redirects_netlify.html`](https://github.com/divinerites/plausible-hugo/blob/main/layouts/partials/plausible_redirects_netlify.html) partial generates a `_redirects` file (or Netlify configuration) that maps [`/js/plausible.js`](https://github.com/divinerites/plausible-hugo/blob/main//js/plausible.js) to `https://plausible.io/js/plausible.out` with a 200 status code. This creates a transparent proxy, making the request appear to come from your domain while still using Plausible's hosted script.

## Complete Configuration Example

Here is a comprehensive [`config.toml`](https://github.com/divinerites/plausible-hugo/blob/main/config.toml) setup that combines self-hosting, fallback tracking, and CSP headers to maximize ad-blocker resistance:

```toml
baseURL = "https://example.com"
title = "My Site"

[params]
  # Self-host the script to avoid domain blocking

  plausible_script_src = "/js/plausible.js"
  
  # Enable 1x1 pixel fallback for JS-blocked browsers

  plausible_fallback = true
  
  # Configure CSP to allow self-hosted scripts and Plausible API

  plausible_csp = "script-src 'self' https://plausible.io; img-src 'self' https://plausible.io"

  # Optional: Enable Netlify proxy (if deploying to Netlify)

  # plausible_netlify = true

```

Place the [`plausible.js`](https://github.com/divinerites/plausible-hugo/blob/main/plausible.js) file in [`static/js/plausible.js`](https://github.com/divinerites/plausible-hugo/blob/main/static/js/plausible.js) and include the partials in your [`layouts/_default/baseof.html`](https://github.com/divinerites/plausible-hugo/blob/main/layouts/_default/baseof.html):

```html
<!DOCTYPE html>
<html>
  <head>
    {{ partial "plausible_head.html" . }}
    {{ partial "plausible_csp.html" . }}
    <title>{{ .Title }}</title>
  </head>
  <body>
    {{ block "main" . }}{{ end }}
    {{ partial "plausible_js.html" . }}
    {{ partial "plausible_head_csp.html" . }}
  </body>
</html>

```

## Summary

- **Self-host the script** using `plausible_script_src` in [`config.toml`](https://github.com/divinerites/plausible-hugo/blob/main/config.toml) to serve [`plausible.js`](https://github.com/divinerites/plausible-hugo/blob/main/plausible.js) from your own domain, bypassing URL-based ad-blocker filters.
- **Enable fallback tracking** with `plausible_fallback = true` to use a 1×1 pixel image when JavaScript is blocked, ensuring page views are still recorded.
- **Configure CSP headers** via `plausible_csp` to prevent security policies from inadvertently blocking your analytics script or fallback pixel.
- **Use Netlify redirects** through [`plausible_redirects_netlify.html`](https://github.com/divinerites/plausible-hugo/blob/main/plausible_redirects_netlify.html) to proxy Plausible requests through your domain while still using their CDN.

## Frequently Asked Questions

### How do I know if ad-blockers are blocking my Plausible analytics?

Check your browser's developer console for failed network requests to `plausible.io` or your custom script URL. If you see blocked requests or 404 errors for the script, ad-blockers are active. You can also compare your server logs against Plausible dashboard traffic—significant discrepancies indicate blocking.

### Can I use multiple ad-blocker bypass methods at the same time?

Yes, combining methods provides the best resilience. Configure `plausible_script_src` for self-hosting, enable `plausible_fallback` for JavaScript-blocked scenarios, and set `plausible_csp` to ensure CSP headers don't interfere. For Netlify deployments, add the redirects partial to proxy requests while maintaining consistent URLs.

### Do I need to update the self-hosted plausible.js file manually?

Yes, when self-hosting, you must periodically update [`static/js/plausible.js`](https://github.com/divinerites/plausible-hugo/blob/main/static/js/plausible.js) to match the latest version from Plausible's CDN. Check the official Plausible changelog or script source periodically, download the updated file, and replace your local copy to ensure you have the latest tracking capabilities and bug fixes.

### Will the fallback pixel track custom events or just page views?

The fallback pixel only tracks basic page views. When `plausible_fallback` is enabled, the [`plausible_head.html`](https://github.com/divinerites/plausible-hugo/blob/main/plausible_head.html) partial generates a 1×1 image request to `https://plausible.io/api/event` with the current page URL and referrer. Custom events requiring JavaScript execution (like button clicks or form submissions) cannot be tracked via the pixel fallback.
