Metrics

Choose a feed metric by specifying which user actions the product values and which actions signal a poor experience. This lesson combines those actions into a weighted score and explains why comparisons need a consistent denominator.

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

For each tweet shown in the feed, log the actions a viewer takes. The case study groups these actions as follows.

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.

Note: 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.
