The power of the broad match modifier
Using the broad match type for a keyword makes your ad eligible to be displayed when a search query or other input includes either the individual words in your keyword in any order, or words closely related to your keyword. The broad match modifier gives you the ability to fine-tune or restrict how liberally Bing Ads matches closely related broad match terms. For more information on broad match and other match types, see Learn about keyword match types.
For example, let's say you create the broad match keyword Hawaii Hotels. A query for Hawaii Rentals might also trigger your ads, since "rentals" is closely related to hotels. But you own a hotel and don't want traffic from searchers looking for rental properties. Your solution? Simply add the "+" broad match modifier to your keyword to make it Hawaii +Hotels. This tells Bing Ads that the word Hotels must be in the query in order for your ads to be eligible to be served.
Let's take a look at some other examples:
