Great question. You create a successful Fiverr gig with research and outreach.

Research
Solid research builds the foundation for your business. Look for the intersection of your best talents with the most popular gigs on Fiverr. Typically those gigs are around marketing, graphics and tech. Study the top sellers to see their focus as well as an holes in the niche you can fill.

Also study profile construction. You'll learn the best wording as well as how to structure your gig so you're protected. For instance, many sellers ask buyers to contact them first before ordering so there is a true meeting of the minds about what is needed, thereby increasing satisfication and rating.

A little keyword research is good, too to make sure buyers can find you.
Do the followings:
1. shorter title
2. unique description
3. add FAQ
4. Add the best tag
5. add video
6. add 3 images
7. add 2 pdf files
