Ad or site content that tries to mislead site visitors threatens customer safety. Microsoft bans such content, including what can be reasonably perceived as being deceptive, fraudulent or harmful to site visitors. Examples include: unsubstantiated claims, free offers or price promises, misleading ads and promotion of third party products and services. Find more specific policies about misleading content below.
Unsubstantiated claims
Advertising that includes unproven claims or endorsements is not allowed.
For example: Ads and sites may not claim an association with government programs when none exists. Advertisers may not use “gov” in ad copy or URLs or show government emblems on their site without documented endorsement from the government.
