Why MercariBoost?
Mercari's algorithm rewards fresh listings. When you relist, your items jump back to the top of search results. Top sellers relist every 20–40 days. With 100+ listings, that means hours of mind-numbing manual work.
MercariBoost is built for sellers who are tired of the relist treadmill. What used to take 3 hours takes 8 minutes.
