When integrating Microsoft Advertising (formerly Bing Ads) campaigns with Live.com, which targeting parameter provides the MOST granular control over user demographics and interests?

When integrating Microsoft Advertising campaigns with Live.com, the targeting parameter that provides the MOST granular control over user demographics and interests is Customer Match. Customer Match allows advertisers to upload their own first-party data, such as email addresses or phone numbers, to Microsoft Advertising. This data is then matched against Microsoft's user base to create highly targeted audience segments. These segments can be used to target ads to specific customers or to create lookalike audiences based on those customers. While other targeting options, such as demographic targeting, interest targeting, and in-market audiences, offer valuable ways to reach specific user groups, Customer Match allows for the most precise and personalized targeting because it is based on the advertiser's own data. For instance, Live.com could upload a list of users who have previously purchased premium subscriptions and then target them with ads promoting new features or services. This level of granularity is not possible with other targeting options.
