I Have cancelled the order it was my first one now please can someone suggest how to rank my gig or get orders with that 0% completion rate on my profile?
There is no such thing as “rank” in the Fiverr search system.
If you want orders, you will have to reach out to your target customers, and convince them to hire you.
you means by reaching out to targeted customers through other social media platforms?
Who are your target customers, and where can you find them? Go to those places, and convince them to hire you. It is very likely that they are not on any social media sites.
Add video to your gig, it will helpful to boast your gig.
