How Search Works
Sneaker Search Engine is built on real market data, not inflated retail prices or algorithm-gamed rankings. Here's exactly how we find listings, score deals, and surface trends.
01
You search. We query live.
When you type a query, we pull active listings in real time. Results come from live marketplace data, not a cached database of yesterday's inventory. We filter by your size (if set), condition preference, and price range before results ever reach your screen.
02
We pull 30 days of sold data.
Alongside live listings, we pull a rolling window of completed, sold transactions on the same model. This gives us a real market baseline: what people are actually paying, not just what sellers are asking. No estimates. No guesswork.
03
Every listing gets a Deal Score.
Our Deal Score (0–100) is computed from four signals, each weighted by how much it reflects real-world value:
vs. Market Median
Price
How far below or above the recent sold median the listing sits. The further below, the better the score.
Sales Percentile
Rarity
How this listing compares to recent sold comps. A listing that undercuts most prior sales scores well here.
Price Trend
Timing
Whether the market for this model is rising or falling. A cheap listing in a rising market scores higher.
Condition
Quality
The physical state of the item. Condition is factored in because it directly affects value and wearability.
04
Trends are ranked by engagement.
The Trending Now feed ranks sneakers by a proprietary Trend Score built from social engagement signals. Recent activity carries more weight than older activity, so the feed reflects what's happening now. A shoe gaining momentum today will always rank above one that peaked weeks ago.
05
Data refreshes continuously.
Live eBay listings refresh with every search. Sold data snapshots are updated on a rolling basis to keep price baselines accurate. Trend scores recalculate as new social signals come in. We store price snapshots over time so you can see whether a market is heating up or cooling off.
06
We never inflate or manufacture data.
Deal Scores are purely algorithmic. There are no sponsored placements and no paid rankings. We don't receive compensation to surface a listing higher. Some links are affiliate links, meaning we may earn a small commission if you buy through them at no extra cost to you. That's disclosed clearly and has zero effect on Deal Score calculations.
