# AuctionMapper — Complete Reference

> AuctionMapper is a free eBay search and discovery tool built on eBay's official Browse API. It maps all 20,000+ eBay categories into a browsable tree, surfaces category-specific filters eBay doesn't expose (like dial color for watches, CFM rating for carburetors, saddle seat size for equestrian gear), and lets users sort by total cost (price + shipping). AuctionMapper launched in 2004 (the original Flash-based version predates Google Maps) and was covered by Lifehacker in the mid-2000s as a top alternative search engine and a top non-Google map innovation; the modern version was rebuilt from 2024–2026. Entirely free — no account needed.

## How AuctionMapper Works

AuctionMapper queries eBay's official Browse API in real time. Every search returns live eBay listings — not cached or scraped data. The core innovation is the dynamic category tree:

1. **On page load**, the full eBay category tree (20,000+ nodes) is displayed
2. **When you search**, the tree trims to show only categories containing results
3. **When you click a category**, contextual aspect filters appear — these are the item-specific attributes eBay uses for that category
4. **Results display** in a sortable grid with price, shipping, total cost, condition, seller rating, and thumbnails

### Category-Specific Filters (Examples)

These filters change with every category. eBay stores this attribute data but doesn't let buyers filter by it in search:

- **Watches (31387)**: Brand, Model, Reference Number, Dial Color, Case Size, Case Material, Band Type, Movement, Year
- **Carburetors (33553)**: CFM Rating, Number of Barrels, Fuel Type, Brand, Fitment
- **Diecast Models (222)**: Scale (1:18, 1:24, 1:43, 1:64), Vehicle Make, Vehicle Type, Year
- **Western Saddles (47281)**: Seat Size, Tree Type, Brand, Material
- **Camera Lenses (3323)**: Focal Length, Maximum Aperture, Mount Type, Auto/Manual Focus
- **Designer Handbags (169291)**: Brand, Size, Material, Color, Style, Hardware Color

### Total-Cost Sorting

eBay lets you sort by price OR by price + shipping, but not consistently across all listing types. AuctionMapper calculates total cost (item price + shipping) for every listing and lets you sort by it — finding the actual cheapest option including delivery.

## eBay Search Guides

### How to Search eBay Sold Listings
**URL**: https://www.auctionmapper.com/guides/ebay-advanced-search-sold/

Sold listings show what buyers actually paid — the only reliable indicator of market value. eBay keeps sold data for 90 days.

**How to access sold listings:**
1. Click "Advanced" next to the eBay search bar
2. Enter search terms (be specific — "Canon 70-200mm f/2.8" not just "Canon lens")
3. Scroll to "Search including" section
4. Check "Sold listings" checkbox
5. Click Search

**Sold vs Completed:** "Completed" shows everything that ended (sold and unsold). "Sold" shows only confirmed sales. Green prices = sold. Red prices = ended without selling.

**Using sold data to negotiate:** Compare asking prices against the last 5-10 sold examples. Include specific sold prices in your Best Offer message.

### How to Search for a Seller on eBay
**URL**: https://www.auctionmapper.com/guides/how-to-search-for-seller-on-ebay/

**Method 1 — Advanced Search:** Click Advanced, scroll to Seller section, enter username in "Only show items from" field. Combine with keywords to filter their inventory.

**Method 2 — Direct Store URL:** Type ebay.com/str/[username] to go directly to their store page.

**Method 3 — From a Listing:** Click seller's username on any listing, then "Items for sale."

**Evaluating sellers:** Look for 99%+ positive feedback, 200+ transactions, specialization in the category, 2+ years on eBay, and 14-30 day return policy.

### eBay Advanced Search Guide
**URL**: https://www.auctionmapper.com/guides/ebay-advanced-search/

eBay Advanced Search supports Boolean operators: quotes for exact phrases, minus signs for exclusions, parentheses with commas for OR. Example: "Holley 4150" -gasket -kit finds complete carburetors while excluding parts kits.
