Try a colorful profile pic
When is the last time you changed your Instagram profile photo?
Did you know you can use an app like Magic Eraser to erase the background of an image and change the background color? This is really handy for profile pictures on Instagram, since the profile picture is very small on the notifications screen. You really want to grab Instagram users’ attention so they follow you back!
Use a photo editor for your photos
When you post photos, make sure that you’re only posting the highest quality photos on your Instagram account.
Take lots of photos of the same shot from different angles, and just pick the best one to post.
Post at least 1x per day
Yes, it may seem like a lot to post once every day, but this is really the bare minimum if you want to grow fast on Instagram.
