Once any Buyer click on your gig it means your gig in good position and eventually when the Buyer doesn't order it will not help to rank your gig up. But you will get some impressions through Buyer clicking on any of your gigs. Keep sharing your gigs on Social Media Platforms, bring traffics from there on fiverr, stay active, spend time on forum. Your gig will rank up soon but obviously depends on your consistency of works.
