1) Remember that comments can be both positive and negative, so receiving a high number of comments is not automatically a good thing. For example, you might have reached users that dislike the communicated content and write negative comments. While you can disaggregate comments by whether they were positive / negative / neutral, it needs to be done manually and, therefore, can be time-consuming.
2) In addition to reporting on a number of comments, consider doing a deeper analysis of what people actually say in their comments. Use such feedback to adjust the campaign’s future communication content.
3) Receiving, for example, 100 comments while your reach was 4,000 social media users is something completely different than when your reach was 50,000 users. Therefore, when reporting the number of comments, always mention the reach.
