There are many methods to get more instagram followers, here i want to make a summary.
First, if you want to get thousands of followers, you must like people, follow people, comment people. Because you like, follow people, then people will follow, like you. Human beings have feelings, so you must increase the frequency to interact with others.
Second, you must post some beautiful, interesting, attractive pictures, or hottest news event. Because people like to watch or see these kind of pictures or photos, people have curiosity. According to my experience, you should use some techniques, like hashtags. For example, use some hashtags like #like4follow #like4followback #follow4follow #follow4followback, then people could search you then follow you.
Third, as for me. I am some kind of lazy, so i use one great software to auto follow, like, comment people on Instagram, this software is called FollowingLike.
FollowingLike is a powerful social media marketing tool, which can run multiple accounts like Facebook, Instagram, Google+, LinkedIn and Pinterest. You can auto-follow, unfollow, follow back, like, unlike, pin, comment, share, add friends and send messages etc with this Super Bot.
What impressed me is that i can combine basic function modules to any complex task to execute any job i want automatically. This software can simulate human operation perfectly to avoid my account to get suspended!
