What are creative specifications?

Every advertising platform, from printed newspapers to online networks, has their own specs and standards for their content.

They include technical, stylistic and editorial guidelines that all advertisers must adhere to so their adverts can be approved and published. Microsoft Ads is no exception.

Why are they so important?

The Global Microsoft Advertising Creative Acceptance Policy and other associated policies such as the Native Creative Acceptance Policy ensure that certain editorial standards are maintained and do not impact negatively on the Microsoft brand or lower the standard of user experience.

These policies govern all Microsoft properties, including:

  • Bing
  • MSN
  • Skype
  • Xbox
  • Windows

The very nature of online advertising means that creative specifications can change rapidly. At any point, Microsoft can refuse to publish any content or make exceptions to these policies in certain circumstances.

Ad style policies

As you’d expect, the ad style policies for Microsoft are comprehensive. Once you’ve read through hand got the hang of them, you’ll see why. They are designed to stop poor writing, clickbait-style headlines and a general decline in ad quality. They promote clear, succinct and factual messaging.

  • Accuracy
  • Keyword relevancy
  • General spelling, grammar and punctuation
  • Unsubstantiated claims
  • Repeated words/phrases
  • Inappropriate or offensive language
  • No unnecessary symbols or punctuation such as multiple exclamation marks of disguising words such as $ale.
  • All ad landing pages must comply with Microsoft Advertising Policies too.

Ad content policies

Content policies are there to make the overall user experience a good one and prevent pages from becoming swamped with low quality, repetitive ads.

  • Do not submit repetitive or multiple similar ads. They will be rejected.
  • If you are running multiple ads, they must be distinct from each other with a unique look.
  • You must use the language of the target market (e.g. English, Spanish), and the landing pages should also be in the same language.
  • Words that are not in the native language can still be allowed if they are used in the target area too (e.g. cafe)

URLs and landing page policies

Microsoft’s ad policies also extend to the landing pages of the ads they display.

  • Final URLs must be a working website. An ad cannot lead to file, email address or a page showing an error status.
