FollowLiker Noob

I recently made a new instagram account in the fitness (female) niche. I am just posting generic fitness inspiration pics for now. I want to build a following in this niche. I'm using instagress to follow and like accounts that follow my competitors. I'm gaining about 20 followers a day. I have heard about FollowLiker but I don't know much about it. I want to gain at least 200 followers a day. Is this realistic? What settings and strategies should I use?

yes it's possible, there are tons of guides here about FollowLiker, please read some

There are some factors that you have to keep in mind.
Instagram is not dumb anymore, they will ban/lock your account if they think you are a bot, so your settings need to be perfect. If you wanna go crazy and earn 200 Followers a day then go ahead and set your follow rate to 500-700 and wait 2 days. Because then you will be banned. I suggest you start of with the settings that you already have in Instagress and maybe increase every setting on followliker 10+% each week, until you reach your 200 follows a day.
