I don't think so, unless you are sourcing the data from the "search" feature of Steemit. Normally, SEO is based on data from searches and inquiries. But I could be wrong :)
I noticed most Steemians would source for articles based on tags/categories, and thought upvotes are a good way to gauge popular topics. However, that don't always correlate to payouts, which I believe is the ultimate goal of most Steemians.
Truth be told, there are still lots of marketing and data potential for Steemit. We're still at the early days of a social blogging giant!
Thanks, yea, it's true, seo is a search engine optimistaion, hence I should optimise for steemit.
