Amazon's A9 Search Engine Launches
Amazon.com's Entry into the Search Engine World launches today. It looks like it's currently using Google's Adwords for its sponsored results, and the main results content comes from its own database, Alexa.com, and Amazon.com. It also has a list of what's new and cool. It does have some interesting features (like built-in "search in the book" from Amazon.com's database), but nothing too wild, other than interface stuff. I do like the fact that I can type "a9.com/search term" into my URL field and it will search.
What I can see happening is better integration of Amazon.com's product listings into the results, as another set of sponsored listings. So if somebody searches for an author, for example, it'll show search results, but also easy ways to buy books from that author. That is one thing that Google will never have is that locked-in product inventory.
