Need help to up bring my gigs

[jazperator]

I have been doing graphic design works since 2016 and already finished more than 1k projects. But, with time my gigs performance were decreased and now it has really bad impression rate. As, I have good previous buyer community, I still getting 5-6 regular orders per week. However impressions or orders are not coming from new buyers. I have tried number of different things to improve my gig quality but no results. Although I have set maximum cpc, promoted gigs getting a click very rarely. And no buyer request suggestions too. I haven't received any new customer since 4 or 5 months. I feel, I may be outside from fiverr algorithm. What should I do to have new customers and improve my gig rankings
