In more detail
A vanity metric goes up and to the right and feels good, but it does not connect to a decision, a goal, or revenue. Follower count is the classic example: 100,000 followers means nothing if almost none of them see or act on your posts. The opposite is an actionable metric, something you can tie to an outcome, like engagement rate, click-through rate, conversions, or saves. Vanity metrics are not useless, they give context, but they should never be the number you report as success on their own. The test is simple: if the number changes, can you explain what to do differently? If not, it is probably vanity.
Example
An account with 50,000 followers posts something that gets 200,000 impressions, which looks great. But only 300 people click through and 4 buy. The impressions are the vanity metric. The clicks and purchases are what actually tell you if the post worked.
