Metrics

The feed-ranking system aims to maximize user engagement. So, let’s start by looking at all the user actions on a Twitter feed.

User actions

The following are some of the actions that the user will perform on their tweet, categorized as positive and negative actions.

Positive user actions

• Time spent viewing the tweet

• Liking a Tweet

• Retweeting

• Commenting on a Tweet

Negative user actions

• Hiding a Tweet

• Reporting Tweets as inappropriate

Now, you need to look at these different forms of engagements on the feed to see if your feed ranking system did a good job.

📝 All of the metrics we are going to discuss can be used to determine the user engagement of the feed generated by our feed ranking system.
