NO! Promoting gigs does NOT increase impressions. Impressions are only increased when other people search for gigs like yours, and only when they search, of their own choosing, in the Fiverr search system. You cannot do anything to guarantee more impressions, because you have no control over how impressions are created. None. Nada. I really wish people would stop telling people that this is how impressions are increased. Your promotion and Fiverr’s impressions on your gigs have absolutely nothing in common. They are not related, in any way.
