Can someone help me with follow back ratio

Hey!

I've been using followliker for some time now and I have a massive problem..
I follow 900 people and like 1500 pictures.
I unfollow after 2 days but somehow only manage to get 20-50 followers a day..
I have a fashion page and my pics are very high quality, I don't have a shitty account.. I'm also targeting the followers of big accounts in the fashion niche and still such shitty results..
Might someone maybe personally help me how to set this up right so I can be getting maybe a follow…

Can someone help me with follow back ratio
