A couple weeks ago I attended the Boston .NET User Group<\/a> to hear Jeffrey McManus<\/a> give a talk on how ebay is using web services. I took a bunch of notes during his presentation, which I’m putting up here semi-edited. The first part of the talk was mainly about ebay the company; how much business they do per quarter, how many users they have,etc.. The second part was about the ebay API, which I was interested in because the company I’m working for now is exploring a similar program, so you’ll see more detailed notes there:<\/p>\n

\ndeveloper.ebay.com<\/a><\/p>\n

45000 product categories
\ncollectibles was the first product category on ebay, it is category id = 1
\nebay did approximately $5.6 billion in cars last year<\/p>\n

105 million registered users as of 3\/1\/2004
\nrate of growth is accelerating quarter over quarter
\n28 countries with a physical presence and localized website
\n20 million items for sale at any one time…
\n1 billion items were listed last year
\n7 gigabits per second outgoing traffic
\n10 billion api hits in 2004<\/p>\n

in december 2003, 1 of every 3 people on the internet came to ebay <\/p>\n

1 in 3 used golf clubs bought in the US are purchased on ebay
\nvalueguide.pga.com uses ebay data to help determine the price of used golf equipment<\/p>\n

Ebay isn’t just for knick knacks: more than 125,000 keyword searches for Louis Vuitton, Coach and Prada on ebay every day<\/p>\n

superpawn.com<\/a>
\n — they build a proprietary POS with ebay and significantly reduced costs
\n — used to cost $23 per item to list & describe each item on ebay (person costs), now approx $.25<\/p>\n

highline auctions<\/a>
\n — custom system integrator with a business around ebay integration, specifically in cars
\n — reduced the time it takes to create a professional listing from 30 minutes to under 3 minutes <\/p>\n

auctionworks<\/a>
\n — solution provider on ebay<\/p>\n

use cases
\n — integration w\/ business tools (quickbooks, excel, sap, etc..) (ie: a donation can be estimated for taxes using a data licensing application)
\n — integration w\/ back ends for medium & large retailers, manufacturers<\/p>\n

‘we make inefficient markets efficient’
\nscarce –> in-season reatail –> end of life–> used\/vintage
\n\t— end of life scenario for retailers
\n\t— products at the end of life can be put on ebay programmatically saving companies the most of having to get rid of excess product<\/p>\n

top level meta categories
\n — sports, tickets, etc…
\n — ‘browseability’ is a one of the challenges
\n — most likely use cases are sellers listing items programatically<\/p>\n

data licensing services
\n — you can purchase data feeds from ebay so that you can find out what the given price for a given car in a given location is
\n — andale.com<\/a>: provides ebay pricing and selling recommendations<\/p>\n
