I thought @prafulkharade had great insight here, but I’d like to expand on something
Imagine you’re coding for Fiverr.
In front of you is a long list of any and all features that exist on the site.
You have the choice to rack and stack the ones that matter most to the ones that matter least, all factoring into an algorithm.
Personally, I would put 5-star reviews pretty high up my list, followed by response rates, followed by average earnings, etc.
My point is that there’s a strong possibility that tips are factored in as well.
Hope that helps! My best advice is to just keep chugging along, do a great job, and everything else will fall into place.
