In questo articolo SocialBakers suggerisce le metriche per i social media…non è sicuramente la prima volta che si trovano formule simili. Ma è comunque utile da condividere per gli addetti ai lavori.
Facebook Average Post Engagement Rate

Twitter Engagement Rate

In social networks, you should be monitoring the following metrics:
- Reach / Fans – Number of your fans and followers, comparing it with competition
- Interactions / Engagement Rate – The interactions your activity and posts generate (obviously, having in mind that you actually do send posts)
- Wall posts / Mentions & Response Rate – Monitoring how well you are interacting with your fans and their questions
