Check the top gigs in your category and change your profile around to be similar to theirs. Don't copy it but use the same keywords, tags, amount of words in title, etc.
Participate in the Fiverr forum and sign in using the Fiverr app on a mobile as well. The Fiverr search algorithm will pick this up and you will begin to rank for certain keyword searches. Once I connected to the app on my mobile my sales really started to pick up.
I also find that an image of a human as the gig pic is best. You can search Pixabay or other royalty free image sites if you don't want to use your own face.
