Gig rotation does happen! No doubt about it I even recently contacted Fiverr support team regarding this and this was the response from them “As for our algorithm, please bear in mind that our indexing algorithm is automatic and changes frequently, however, this is temporary and that re-indexing of Gigs happens constantly and sometimes, Gigs with great ratings can get pushed back.” This makes clear that gig rotation happens irrespective of your good performance This way, new sellers also get chance to be on first page and this is what makes Fiverr unqiue from other freelancing platform
