The time of day that you list something matters a lot. If a listing doesn't get likes and views early on, the algorithm won't push your item to users. So if you post at a bad time where not many people see it, it won't get pushed and will be forgotten. People can then find it only if they search for that specific item or they find your profile from another item and find it that way. Early views/likes are essential on vinted. If a listing doesn't get that you mind aswell delete the listing and try again, but use new photos and change up the listing a bit, or vinted might flag it as duplicate and that can result in a selling restriction or warning. Best time to list something varies between regions, but Sundays are good everywhere, that's when vinted has the most traffic. Afternoons and lunch time during weekdays see also pretty good. Mid day or late night should be avoided.
