Sluggish
Inventory is sitting. The usual cause: you’ve been undercut and haven’t responded. Check the lowest competitor on your slow listings.
Low STR is usually a price problem: check the lowest live competitor and your break-even floor.
When listings stop selling, sellers blame the algorithm, the season, or the economy. Sometimes that's right. But for anything with competition, the boring explanation wins most often: someone listed it cheaper, and buyers found them first. Your listing didn't get worse — your price stopped being the winning price.
The fix isn't panic-slashing. Work out your break-even floor, check the lowest live competitor, and price to win above the floor. Undercut does that loop automatically on every listing, 24/7 — read how the floor works.
Undercut reprices to beat the lowest competitor — never below your floor. Start free, no card.

What is a good sell-through rate on eBay?
It varies by category, but as a rough 30-day benchmark: above 80% means demand outpaces supply, 40–80% is healthy for most resellers, 15–40% is sluggish, and below 15% means inventory is stalled. Commodity categories (media, electronics) should run higher; rare collectibles naturally run lower.
How do I calculate sell-through rate?
Items sold in a period divided by total items available (sold + still active), times 100. Example: 12 sold with 60 still active = 12 ÷ 72 = 16.7%. Normalize to 30 days to compare months of different lengths.
Why did my sell-through rate drop?
The most common cause is silent undercutting: a competitor listed the same item cheaper and is now winning the sales you used to get. Other causes include seasonality, rising shipping costs pushing your total price up, and stale listings losing Best Match rank.
How does repricing improve sell-through?
For price-competitive items, sitting above the lowest credible competitor costs you most of the sales. A repricer keeps you at the winning price automatically — and a floor-first repricer like Undercut does it without ever selling below your minimum, so velocity improves without margin collapse.
