How to: measure the potential audience size of a geo-targeted Facebook post

8th April 2011

Often times as a page administrator, I find the need to send out a Facebook post to a limited number of fans through geo-location. When measuring the success of these posts, or deciding if they will be impactful,  it can be tough to figure out the potential reach of a post given the geo-location of your fan base.

For instance, if you have an audience of 1 Million fans and a post gains 600,000 impressions, you know 60% of your audience had the potential to read your post. Using Facebook ads, we can more closely determine the potential audience of your geo-targeted posts.

1. Visit: Edit Page –> Marketing –> Create an Ad

2. Create your Facebook Ad. Be sure to select the same locations as you wish to target for your geo-targeted post. Also, be sure to only target those users already connected to your Facebook page.

3. To the top right side, you will be given an approximate reach to your Facebook Ad, and by relation your Facebook post.

While the numbers may not be perfect, this can be particularly helpful in deciding which markets to target or how impactful a future post may be. Happy targeting!
