Due to a rise in misleading ad experiences stemming from third-party technical support providers, Google has begun restricting ads in this category globally.
In the coming months, we’ll develop a verification program to ensure that only legitimate providers of third-party technical support have access to our platform. Until such time, all advertisers who promote third-party technical support will be affected by this change; no third-party technical support ads will be allowed.
