In my last post I explained that I was investigating the interrelation of keywords (or tags) in eBay titles to see if they could help me to producing some kind of dynamic categorization for the eBay site. I completed my research yesterday and wanted to share it here, the answer definitely seems to be yes and that really excites me.
The experiment involved me pulling all the titles for the 77750 listings related to the word iPod on eBay.com and saving all those titles into a database. I then split each title into individual words and entered them into a mySQL database then running an SQL query to give me the DISTINCT keywords and the COUNT of how many times they occurred in the titles.
What I found was absolutely fantastic. The keyword ipod had a 31% probability of association with the word Nano, 28% with case and Apple, 27% with video and so on.
Dynamic categorization and keyword discovery carefully optimized by millions of sellers over 10s of thousands of items daily with billions of dollars of GMV in any category of item you could want exposed for free! That’s gotta be worth something to someone 🙂
