Sometimes a person or business will put questions in their posts just to get their engagement numbers up and then not even read the responses. It's like a band taking requests and then playing a song that no one asked for.
Does putting questions in your posts help your numbers? Often it does. Because the more comments a post receives, the more people the algorithm will show that post to. But if you are not going to read the answers, much less respond to them, then you have no class.
What is sad is that “experts” tell people to do this. I have heard or read variations on this conversation a number of times ...
“Put questions in your posts so that people will comment and the platform algorithm will reward you for it.”
“But I'm not sure I will be able to read all of those responses.”
“Doesn't matter! Don't read any! No one will know.”
Makes you feel all warm and fuzzy inside.
