On Mercari, Depop, and Vinted, search ranking decays over time — newer listings appear above older ones. The Refresher edits your listings on a schedule (a tiny price tweak or a re-save) to reset their freshness clock.
Mercari
Refresher does a no-op edit (saves the listing again with the same fields). Mercari's algorithm treats this as fresh, like you just listed it.
Depop
Closo bumps Depop listings via the same flow Depop's own “Boost” feature uses, except free. We rotate which 20 items we boost each cycle.
Vinted
Vinted's search ranks freshness heavily. We re-save listings older than 48 hours.
Poshmark
Poshmark uses Sharer instead of Refresher — sharing is what bumps you in their search. The Sharer covers Poshmark.
eBay / Shopify
eBay and Shopify don't reward freshness, so there's no Refresher for them. Save your time — focus on titles and item specifics.
