The number of people who can be reached by your targeted audience. You’ll see an estimate of this, similar to the one you see when creating an ad. To examine the gap between how many people you’re really reaching and how many people you could be reaching, use the Audience graph. Increase your bids and budget to reach a larger portion of your intended audience. You can target narrowly, for example, based on their level of education or income. Age, region, gender, job title, and other factors can all be used to target your audience.
