I'm currently using instagress and I'm using the follow/unfollow method plus likes. My accounts range from 15% follow back to below 10% after averaging out follow/unfollow days over a period of time. I feel that it may be a bit low, but I wanted to see what everyones followback ratio is, just to give me a better idea. I do understand niche also plays a role. I'm currently playing around with filters and follow sources. But are there any tips from the veterans to up the ratios?
