Re: Any instagram user here? insta blogger?
You want to promote brands on your account without any monetary gain. Thats very kind of you. Im sure the brands will love it. Promoting other brands or products is not a way to gain followers. Its a turnoff actually.
You first need to create a following and then push the brand promotion.
Your real question should be: How should I gain followers on instagram?
Thats a million dollar question
