Amazon launches search engine (A9)

Hmm…Amazon ended beta testing and has officially launched it’s very own search engine called A9.

I just tested a little and it really reminds me of Google especially when I search for my own sites. I guess I should read a little as I’m really interested what type of ranking etc they’re using to optimize their search results, what kind of crawler they’re using etc…

update: now that makes sense, A9 uses the Google search engine along with other helpful resources like IMDb. So I guess the only “true innovation” is their user-specific preferences (cookies need to be enabled). I guess they’re using the history etc for statistics and placement of results (similiar to the “customers who bought x also bought y” on amazon)…
