can i post a my gig to take some suggestion or views?
Yep, if you want to. You can use the Improve My Gig section to ask for advice and the My Fiverr Gigs section to advertise. In both sections, you’re allowed to post links to your gigs.
not to advertise its for some suggestion to more change or not in gig?
That’s fine. You can share your profile link here. You won’t get in trouble.
