It is nobrainer for any blogger. As a part of promotion you have notify in social media platforms. Many of them allow you and are created for digital talk. We are also seeing good response to social media messages. Big personalities of various fields are present on social media and you get an occasion to reply to their messages and indicate your blog posts as having some answer to the question that they are posing. I find my tweets given as answers to the tweets of big names getting 500 views. My own tweets may not be getting big number of views. But a tweet given as a reply gets many more tweets. That same thing may be happening on other platforms.

Then you get maximum benefit for your promotion effort.
