[Launching Promoted Gigs]

Also I don’t really understand why it says it’s only for gigs with at least 30 reviews. Surely gigs with less than 30 reviews would need promotion a lot more than those with more reviews?

I think it’s not about what gigs or sellers need, the idea is to promote proven gigs that would be appealing to buyers.

That’s totally incorrect. Just because a gig has no reviews because it’s new, doesn’t make it unreliable or unprofessional. It is super unfair that there are some newly joined sellers that have waay more experience in a certain area than say one “top rated seller”.
