Having good follower relationships is the most natural way to increase your interaction

Social media aside; In our daily relationships, we share more with the people we love and the people nearby. In this way, we have more information about them. It allows you to primarily interact with people with whom your relationships are strong, as in reality. 

If you see a company or a person on your Instagram page, here are the reasons:

How does Instagram choose who will post your posts?

1) Users with which you have high interaction

If you regularly like some users' posts and comment. Instagram will think you have a strong relationship with these people and will highlight their posts on your page; or your posts will appear on their pages.

2) Timing

Instagram always wants to present and promote new content to users. Thanks to the hashtags you use in your content, your posts will be directed to the page of users who are related to the subject and use similar hashtags in many searches or posts. In this context, predicting how many users are active in the sharing time you make will make you stand out.

3) Likes and Comments

As we mentioned before, as the number of likes and comments about your content increases, the percentage of posts you create will increase on your followers' page.

4) Direct Shares

If you shared a direct post with a private message to a user. Instagram thinks that you have a tight connection with this person and puts forward the display of the content shared by this user.

5) Profile searches When

Users search for each other's accounts, Instagram perceives this situation as a clue and enables these people to connect with each other.
