Using the broad match modifier

Learn about the broad match modifier, how to use it, and how it will impact the eligibility of ads to serve.

If you find that some of your broad match keywords are matching on search terms that aren't relevant to your business, you can use the broad match modifier to fine-tune or restrict how the broad match is being applied.

What are broad match modifiers?

Let's say you create the broad match keyword Hawaii Hotels. A query for Hawaii Rentals might also trigger your ads, since "rentals" is related to hotels. But you own a hotel and don't want traffic from searchers looking for rental properties. The solution? Simply add the "+" broad match modifier to your keyword to make it Hawaii +Hotels. This tells Microsoft Advertising that the word Hotels (or one of its close variations) must be in the query in order for your ads to be eligible to be served.

Here are some examples of how your ad might show:

For English, French, and German ads in the United States, United Kingdom, Australia, Canada, France, Germany, and India, close variations of words with the broad match modifier can also trigger your ad. Examples of the types of close variations that are considered include:

  • Plurals: The keyword luxury +resorts will match the query luxury resort.
  • Stemming: The keyword +swim team will match the query swimming team.
  • Misspellings: The keyword Hawaii +vacation will match the query Hawaii vacaton.
  • Abbreviations and acronyms: The keyword Redmond +Washington will match the query Redmond WA.
  • Word blending and splitting: The keyword +super +market will match the query supermarket.
  • Common spelling variations: The keyword community theatre will match the query community theater.
  • Punctuation: The keyword real estate will match the query real-estate.
  • Accents: The keyword +café will match the query cafe. Accents are not considered for close variations for English ads in the United States and Canada.
  • Reordering: The keyword chicken teriyaki will match teriyaki chicken. Reordering occurs only if it doesn't change the meaning of the query.
  • Stop/function words: The keyword tv schedule tonight will match tv schedule for tonight. Stop/function words (for example: is, a, the, on, for, in) may be ignored if they don’t impact the intent behind a query.
  • Synonyms and paraphrases: The keyword glucose levels normal range will match normal range for blood sugar.
  • Implied words and same search intent: The keyword Contoso airlines will match Contoso flights airlines.

If you find that close variations to your broad match modifier are triggering your ad incorrectly, add those close variations to your negative keywords.
