Hi @parisingh try to comment something very interesting and cool about the content what an author made and spends it's time and energy and definitely you will get an upvote, refollow or maybe your post resteemed by the respective authors, but it's not a good way to say for upvote and follow up.
You can join Steemschools discord servers for more information, here more than 8000 Steemians like me and you are available for support each other.
Good luck.
