A CTA is a call to action, and it can serve a number of different purposes. You might want someone to join your mailing list, or book a call.. or you might simply want to build more of a relationship with your followers, and get your post seen by more people, by asking a question people really want to answer.
Arguably, just about every post should have a CTA of some sort. because the algorithm notices when people comment, and assumes that means the post is interesting and that more people should see it. So, even if you aren’t currently ‘selling’, you still want to get a conversation started. It is SOCIAL media, after all.
