Vi segnalo questo post, che da' qualche dato sui livelli di engagement ottenibili su Facebook.
Due punti chiave:
a) Engagement is measured in interactions. On Facebook that translates into likes and/or comments.
b) above 1% engagement rate is good, 0,5%-0,99% is average and below 0,5% engagement likely means that you need to realign your messages to that of your audience’s expectations and in the process attract more compelling and engaging messages from your community members.
