[Social Media Marketing for Fiverr Gig]

Many peoples and Fiverr recommend social media marketing when you publish your Fiverr Gig. 
As a person who hasn't too many friends on social media and no more specific friends who can buy my gigs for the future. So, My question is, How can I do Social Media Marketing for Fiverr Gigs?

Your all suggestions are very important to me. 😀
Thank You!
