Is it possible for impression and clicks to decrease? if yes, then why?
Of course! They decrease when your gig goes to the last pages of the category or when less people search for that category or keywords of your gig.
i wait since 3 months.but not rotate gig to first page.its hold on last page
sure. It is a ranking matter
It appears you sell logos. There are 140,000 logo gigs on Fiverr. It takes awhile to get to the front of the line.
