Microsoft Advertising

Report March 2026

Submitted

Executive Summary 


Microsoft Ireland Operations Limited, the provider of Microsoft Advertising in the European Union (EU), submits this report outlining its implementation of the commitments under the Code of Conduct on Disinformation for the full calendar year 2025 (“reporting period”). Microsoft is committed to preventing the misuse of advertising services to disseminate or monetize disinformation and to supporting broader efforts to protect the integrity of the information ecosystem. 

Microsoft Advertising serves ads displayed on Bing Search, other Microsoft services, and third‑party properties. The platform connects advertisers, who provide advertising content, and with publishers, who display these advertisements on their services. To mitigate the risk of disinformation, Microsoft Advertising applies distinct policies and enforcement measures to advertisers and publishers, including restrictions on non‑compliant content and placements and actions against parties that fail to comply with applicable requirements.

During the reporting period, Microsoft Advertising continued to apply these policies and enforcement measures, focusing on targeted, policy‑based enforcement supported by transparency and cooperation with relevant stakeholders, consistent with the role of advertising services in the information ecosystem. Microsoft Advertising will continue to evaluate and refine its policies, enforcement processes, and reporting practices in line with the Code’s commitments and evolving risks.

Measure 2.1
Relevant Signatories will develop, deploy, and enforce appropriate and tailored advertising policies that address the misuse of their advertising systems for propagating harmful Disinformation in advertising messages and in the promotion of content.
QRE 2.1.1
Signatories will disclose and outline the policies they develop, deploy, and enforce to meet the goals of Measure 2.1 and will link to relevant public pages in their help centres.
As described in QRE 2.2.1, Microsoft Advertising maintains network-wide policies, implemented in December 2022, that prohibit the monetisation of disinformation and the placement of advertising on or adjacent to disinformation content. These policies prohibit ads or sites that contain, promote, or direct traffic to disinformation. Enforcement may rely on internal signals and trusted third-party data sources to reject, block, or remove ads or sites, including blocking at the domain level where landing pages or sites violate policy.

Please see here for our main policy page.
SLI 2.1.1
Signatories will report, quantitatively, on actions they took to enforce each of the policies mentioned in the qualitative part of this service level indicator, at the Member State or language level. This could include, for instance, actions to remove, to block, or to otherwise restrict harmful Disinformation in advertising messages and in the promotion of content.
Microsoft Advertising assesses the impact of its enforcement actions by reporting on blocked ads, customers suspended as a result of risk detection, and impressions generated prior to enforcement.

“Blocked Ads” are the individual advertisements (or ad creatives) loaded in the Microsoft Advertising campaign system that we blocked. Because these ads are blocked globally, we are reporting the same number across all Member States for the reporting period.

“Unique Domains” means the web domain or URLs that the Unique Ads would have directed customers to. Because these ad domains are blocked globally, we are reporting the same number across all Member States for the reporting period.

“Customer suspensions” means the suspension of advertiser access to Microsoft Advertising services for willful or repeated violations of policies relating to phishing, malware, or payment instrument fraud. Suspended advertisers cannot serve ads until the violation is remedied.

“Blocked Impressions from Suspended Customers” means ad impressions generated by customer prior to suspension. Where customers are suspended before ads are served, no impressions are recorded.
