Hello there I’m fairly new seller so it’s up to you if you want to take this tip or leave it. I’ve seen some sellers giving “unlimited revisions” in their gig. Giving unlimited revision has one good advantage that the client may trust you regarding quality of delivery but it may backfire at you.
You should clearly define the number of proposals you’re willing to offer like 2, 3 or whatever you want. But if you decide to give unlimited revisions then buyer 's mind will tell him that the delivered product is not good even if it’s good because they want more revisions as it’s free. Also CS may not be able to help you with this if buyer keeps asking for revisions as you clearly said you’ll provide unlimited revisions in your gig.
Just my thoughts,
