Welcome to the Fiverr forums.
That first thread that @coerdelion shared, I would especially recommend the (DES) section.
Check out the Tips For Sellers category: You’ll find hundreds of threads offering advice on a variety of things to consider and/or improve. (Note: Not all advice can apply to all gigs or categories. Be sure you check multiple sources as there are some false tips, even among the top threads.)
