As you select your targeting options, you can see an estimate of the audience size you'll be able to reach in the forecasted results window. The minimum audience size required to run an advertising campaign is 300 members, but we suggest a minimum of 50,000 to drive results for your campaign.
-
For Sponsored Content and Sponsored Messaging, we suggest a minimum of 300,000
-
For text ads, we suggest you target between 60,000 and 400,000
-
If you include multiple attributes from the same targeting facet, your audience size will increase. Members will only need to match one of the attributes selected within the same targeting facet to be included in your audience.
For example, if you select multiple job titles when setting up your audience, members in your audience could have any of the job titles selected.
-
If you add attributes to the Narrow audience further section of targeting setup, your audience size will decrease because your audience must match one attribute from each targeting facet included in your audience.
For example, if you select multiple job seniorities and job functions for your audience, members in your audience will need to match one of the selected job seniorities and one of the job functions.
-
If you Exclude targeting facets, your audience size may decrease. Excluding targeting facets narrows your audience by removing members who meet the excluded criteria.
For example, if you include a country in your targeting but exclude a specific city, your audience size will be smaller than an audience without excluded criteria.

Matched Audiences allow you to create custom audience segments based on an uploaded list, retargeting, or third-party integration.
-
When you include multiple Matched Audiences segments of the same audience type, it will increase your audience size.
For example, if you include multiple website audiences, your audience size will be larger than if you include one website audience.
-
If you include different types of Matched Audiences segments to your audience, it will decrease your audience size. Your audience size will also decrease if you exclude Matched Audience segments.
For example, if you include a website audience and company audience, members in your audience will need to match with both segments to be included in your audience.
