Hi @vimukthi,
You are definitely right. Steemit is a SEO monster. If you use keywords correctly in titles, subtiltes and throughout the text, even without upvotes and comments, your post might have a very high visibility on google thanks to steemits ranking. I think that many people haven't realized the power of this and there is still a lot of potential to develop this aspect and use Steemit for SEO.
Thanks a lot for your comment and for the resteem!
