Here let me spoonfeed you!
1. If it's a new account let it age for a week or two.(just like a few profiles here and there. Follow 3-5 big accounts view stories, just normal actions)
2. Add a post or two after that and a description too but no links.
3. Choose a hashtag or a famous account in your niche and start following its followers.
3.1 The first day you just follow 10 people from that account.
3.2 Second day you double it. i.e. 20 people.
3.3 Next day do 40 or maybe 35 keep increasing this way.(100...150...200...)
3.4 At around 300-400(or maybe more) you'll get a temporary follow ban from Instagram.
3.5 Now you know that's your follow limit. just keep following that many each day now.
(PS: don't forget to unfollow too. Suppose you follow 100 people today then unfollow somewhere around 50. maintain the balance)
(PSS: you can add the link too after a few days doing follow unfollow.)
4. Keep liking a few random pictures too just to keep you off the radar.
There you go!! This should be enough to get the ball rolling.
