Performance analysis is the practice of assessing the effectiveness of your content in terms of how it meets your goals. This can be done by measuring metrics like the number of impressions, clicks, and engagements.
Some platforms have built-in tools that can be used to check the performance of your content.
For example, on Instagram Insights, you can see a breakdown of how many likes and comments your post received, as well as how many people interacted with it by liking, commenting or sharing it with their friends. You can also see how many times the post was re-shared across different accounts.
On TikTok, you can see which videos are getting the most views per day and what the average length is for those videos.
