First time posting here , i started fiverr in 2019 and then didn't use it for 3 years , now i'm back

the competition on fiverr is increasing meaning that people are getting less orders , i used to get 2-3 orders of 90 usd a day in 2019 . Now it's been about 4 weeks i only got 5 orders .
First thing i tried is , buying reviews from different places , then post in pinterest and twitter (offer discount and stuff) but i still don't get clicks and i don't know why .
i still want to exchange reviews hoping i will get traffic to my fiverr account .
But other than that , i don't know what to do
