Depends on the ad and the businesses reason for the ad. Social media sites have reporting for businesses who advertise that can show different info. So one ad you might be trying to get as many people as possible to see it. While on another you may be tracking how many people click the ad or how many people click and purchase something.
TLDR; Platforms like Reddit and Facebook have tools that let you see performance.
