I think it’s important to understand what an algorithm is and how it works and also understand the nature of competition.
It is NOT a system that says “This gig will go here and this gig will there.” It is a program of conditions that determine a set of programmed actions.
Many of those conditions have absolutely nothing to do with your performance and everything to do with Fiverr’s business goals. We don’t know what those are and even if we did we likely couldn’t control them (at least not ethically). A company would never reveal it’s algorithm program because then people would use that to game the system and competitors would have an edge over Fiverr, too.
Also, there are literally thousands of sellers here who fit the criteria you describe. There are what, 40 spots per page? If you do the math, you’ll see it’s not possible for everyone to rank well under the rationale you describe – and Fiverr wouldn’t rank people that way, anyway.
