I am on level 2 seller. I have 4 gigs. Till yesterday, 14 orders have been completed in the last 1 month, most of which are old buyers. Out of these 12 are 5 stars and 1 is 4.5 stars. My gig has the promote option turned on. But the problem is that my gig is nowhere to be found by searching according to niche. What could be the reason?
