You can do this directly in the page code, with no server or hosting configuration needed. ## 1. Add the privacy setting In your page's ``, add: ```html ``` Example: ```html ``` This setting tells the browser not to send the source page URL in the `Referer` header. --- ## 2. Install the Pixel as usual After adding the setting above, you can install the Meta Pixel as usual. Use the code provided by **Meta Events Manager**. You don't need to change the standard Pixel code because of this setting. The structure will look like this: ```html ``` > **Important:** place the meta tag before the Pixel code. --- ## 3. If you use `noscript` Meta also provides an alternative that uses an invisible image. In this case, you can add `referrerpolicy="no-referrer"` directly to the element: ```html ``` Replace: ```text YOUR_PIXEL_ID ``` with your Pixel ID. If you already use the `noscript` provided by Meta, just add: ```html referrerpolicy="no-referrer" ``` to the ``. --- # How to check that it's working After installing the Pixel, we recommend checking the request directly in the browser. ### 1. Open DevTools In Chrome, press: ```text F12 ``` Then go to: ```text Network ``` and reload the page. ### 2. Look for Meta requests In the Network search field, search for: ```text facebook.com ``` or: ```text /tr ``` ### 3. Open a request Click one of the Pixel requests and look for: ```text Request Headers ``` Then check the field: ```text Referer ``` With: ```html ``` the offer page URL should not be sent in this field. --- # How to tell if the Pixel is working Besides checking the Referer, also confirm that events are arriving normally in Meta Events Manager. You can test, for example: - PageView - ViewContent - Lead - CompleteRegistration - Purchase The events and parameters used depend on your Pixel and page configuration. --- # Common mistake: configuring only the noscript If you use Meta's JavaScript Pixel, configuring only the noscript: ```html ``` is not enough. The right approach is to configure the page: ```html ``` This way, the referrer policy is applied to all resources loaded by the page. The `referrerpolicy="no-referrer"` on the `img` should be used as additional protection for that specific request. --- # Common mistake: placing the setting after the Pixel Place: ```html ``` at the beginning of the ``, before the Pixel code. Example: ```html ``` --- # Checklist Before finishing, make sure that: - The `no-referrer` meta tag is in the ``. - The meta tag is before the Pixel code. - The Pixel is installed correctly. - Events are showing up in Events Manager. - The Pixel request is not sending the offer page URL in the Referer. ## Summary In most cases, you only need to add: ```html ``` to your page's `` and install the Pixel as usual. If you also use Meta's noscript, add: ```html referrerpolicy="no-referrer" ``` to the `` element.
