Conversion tracking update on Bing Ads

Last year, Apple Inc. introduced a feature called Intelligent Tracking Prevention that impacts how conversion tracking works on the Safari browser. To help ensure that conversions continue to be reported accurately and in full across your Bing Ads campaigns, the auto-tagging of the Microsoft Click ID in ad URLs is now required.

How does auto-tagging of the Microsoft Click ID work?

When you enable auto-tagging of the Microsoft Click ID, it allows Bing Ads to automatically add a unique click ID to the landing page URL after a customer clicks your ad. The landing page URL may look something like this:

The Universal Event Tracking (UET) tag is a critical part of conversion tracking on Bing Ads. Once the auto-tagging of the Microsoft Click ID is enabled in the settings option, the UET tag will set a cookie on your website’s domain to capture the Microsoft Click ID from the ad URL that brought the customer to your website. This allows Bing Ads to connect any conversions from a visitor back to the search ads that may have assisted in that conversion.

In addition, the UET tag will set a session ID cookie on your website’s domain to help improve the accuracy of conversion tracking. You can learn more about the cookies set by the UET tag, including how to opt out, by visiting our Help page.

Note that only the JavaScript version of the UET tag will set cookies for the Microsoft Click ID and session ID. For this reason, we recommend the JavaScript version to more accurately track conversions across all browsers, including Safari.

How to enable auto-tagging of the Microsoft Click ID

You can enable the auto-tagging of the Microsoft Click ID on the URL options page of the Shared Library by checking the box, “Add Microsoft Click ID (MSCLIKID) to URLs to allow conversion tracking.”

This option will be selected by default when creating new conversion goals.
Note that this setting is managed at the account level. If you have more than one account, make sure to check the box within each account.
