Reach

The term reach, as it applies to social media, defines the number of unique users who have seen your content within a set time period—whether or not they've interacted with it in any meaningful way. This is a key metric in digital marketing because it gets at the very essence of how 'big' an audience your content has. To put it another way, reach is a measure of how many different eyeballs have taken in what you're pushing across whatever platform you're using—this could be Facebook, Instagram, Twitter, or LinkedIn, among others.

Now, when someone talks about 'boosting their reach,' that usually means they're doing something above and beyond just naturally letting their content fall where it may through the algorithms of the various platforms and the timelines of their users.
