NOTICE: Change required to banner ad widgets

Recently Chrome (and Edge, which runs on Chromium source code) made a change to the way requests are made within a web page to improve browsing privacy. The default policy for "referrers" (metadata indicating the URL that a request originated from, which we use to determine banner keyword placement information) has changed, requiring an explicit referrer-policy listed in the script tag powering the banner ad.

This means that without adding this referrer policy to your banner ad code, Chrome and Edge (and potentially more browsers in the future) will not pass the information required for your banner ad features to work correctly. To fix this issue, you must add the referrer policy "no-referrer-when-downgrade" to any banner scripts used on your pages.

Existing banner widgets on your web pages look like this:

<script src=""></script>

To make sure your banners are properly displayed on the correct page based on that page's keywords, you must add the referrerpolicy value to the script, like this:

<script src="" referrerpolicy="no-referrer-when-downgrade"></script>

Adding the referrerpolicy="no-referrer-when-downgrade" to your banner scripts will override the Chrome default policy and fix banner placement issues.
