Welcome To The Fiverr & Fiverr Community!
First please make sure that you have completed your Gig SEO properly.
I will suggest you to create the complex programming Gigs also. Because no one can say that which Gig will rank batter.
Gig image is the most important. Because a buyer will first focus on your images and click on the image mostly. So make sure your Gig image is attractive.
More Gigs mean More change of orders (Note: I have currently only 1 Gig because I deleted my other Gigs. Because I will create Gigs on other categories now to get more sells)
View other sellers Gigs at your category. And take idea properly. How they created the Gig images, title, description, Price, Tags
