Disable Topics API

外掛說明

This plugin adds an HTTP header to your WordPress website that disables Google’s Topics API tracking. The following header will be added:

Permissions-Policy: browsing-topics=()

If an existing ‘browsing-topics’ value is found, the plugin will not change that value or add an additional one.

More information about the Topics API and it’s predecessor “FLoC” can be found here:

安裝方式

This plugin has no settings. Simply install and activate it to exlude your website from Topics API calculations.

常見問題集

I’m not using Chrome, why would I use this plugin?

This plugin does not exclude you (as a user of the web) from Topics API tracking. It excludes your website, and thus protects your website’s visitors. Many of them will probably use Chrome.

How can I check if this plugin works?

This plugin attempts to add an HTTP header. You can use your browser’s Dev Tools to check whether it gets added properly.

  • Visit any page on your site using the browser of your choice.
  • Press F12, or right-click anywhere on the page and click “Inspect element”.
  • Switch to the network tab in the newly opened development tools pane.
  • Turn on recording (if it’s not already active), and reload the page.
  • You’ll see a number of requests appear as a list. The top one is usually the page itself.
  • Click that line to open up its properties.
  • Look for the header under “Response headers”.

I’ve also set up an online FLoC header checker. Simply enter your website’s homepage URL to see of the header is present.

I don’t see the header, what could be wrong?

HTTP headers can get added and/or removed on many levels in the server stack.

  • By WordPress itself (which is what this plugin attempts).
  • By the web server (NGINX, Apache, etc).
  • By caching layers, proxies, etc.

Please note that there’s a known issue with many page caching plugins where the ‘hook’ that this plugin uses does not work. This is a fundamental issue in WordPress and not something that’s easy to work around. If the header does not get added by this plugin, your best option is to see if it can be added on one of the other levels. Or ask your system administrator to do this for you.

If you’re using WP Super Cache, make sure the ‘Cache HTTP headers with page content’ option is checked.

I'm installing this plugin over a bunch of sites on many different hosting providers. So far has worked flawlessly.

If you do not want to use a plugin, just add the following lines to your function.php function disable_floc($headers) { $headers['Permissions-Policy'] = 'interest-cohort=()'; return $headers; } add_filter('wp_headers', 'disable_floc');

After reading about Federated Learning of Cohorts (FLoC), I knew I wanted my site pages excluded from FLoC analysis. Thanks for making this so easy to implement. Added your plugin to my site this morning, confirmed the setting, and it's good to go.

While I hope to see this in WordPress core soon, this is a great alternative.
