When assessing Facebook Pages, there are a number of metrics that can be used to gauge their success. Here are a few key ones to consider: 1. Reach: This metric measures the total number of people who have seen a particular post. A high reach means the post is being seen by a large number of people, which can be an indication of its success. 2. Engagement: Engagement measures the level of interaction people have with a post, including likes, comments, and shares. A high level of engagement can indicate that people find the content compelling and are interested in it. 3. Conversion: Conversion measures the number of people who take a desired action as a result of seeing a post. This could include clicking through to a website, signing up for a newsletter, or making a purchase. 4. Follower growth: Follower growth measures the rate at which a page is gaining new followers. A high rate of follower growth can be an indication that the content being posted is resonating with people and driving them to follow the page. 5. Referral traffic: Referral traffic measures the amount of traffic a page is driving to external websites. This can be an indication of how effective the page is at directing people to take a desired action. Overall, when assessing Facebook Pages, it is important to consider a range of metrics in order to get a holistic picture of their success. By tracking metrics like reach, engagement, conversion, follower growth, and referral traffic, product managers can gain valuable insights into how well a page is performing and identify areas for improvement.
