My gig has gone down in ranks. How can I get it back up?

[moonbootmayhem]

So on Fiverr, I sell auto-purchasing bots for website like Best Buy, Newegg etc. and about a month ago when I searched up “Best Buy Bot” in Fiverr, I was always in the top 5 options out of hundreds, but recently I’ve checked and I am no where near the top at all. What is this system based on? Are the more clicks you get the higher up you are in the ranking? Im really looking to improve my gig rank to get more sales again but I just dont know how.
