i am a very social person, ready to comment,like and share ur post at any time No matter how often you post on Instagram, I can guarantee you look back at who's liked and who hasn't. Engagement and showing interest in people's posts has been listed as one of the essential ways to be successful on Instagram. But what is the algorithm behind how Instagram orders the people that have liked your posts? How does Instagram rank likes? The most common explanation is that the people you see first in your likers list are those who you engage with most, and they engage with you the most. These are the Instagram users you search for, like and comment on their photos, or direct message – and they do it back.
