"Alexa has lots of information. Alexa, you’ll recall, had archives of web pages that we later came to know better in the form of the Internet Archive. And it did Related Links for a URL before Google did, with an accompanying place on the Alexa toolbar to rate site quality and get metainfo on the site itself. Now remember, Amazon bought Alexa a couple of years ago. So, what if you layer those Amazon features, and Amazon’s UI, on top of the information of Alexa and the feature set of the Google API? Answer: Alexa Web Search, the intersection of Amazon and Google. Complete with thumbnails of search results and an option to write a review of a site you find."
