What is the proper way to share a gig to get impressions, views, and sales?
I think here you mean Market your Gig.
Sharing is easy, get the Link and paste it places. Just take care as pasting links to random (in everyone else’s view) Fiverr gigs can get you busted, banned and otherwise word beginning with B and ending in _gg_r_d.
Marketing is where you find a part of the market that you show the need for your service based on their point of pain, convince them that you is da man (woman, child, goat), and direct them to your pit of evil, sorry I meant website, which has a “Solve My Pain Now!” button that launches your fabbo Gig.
What else did you think you needed, or could do?
