Announced at threadwatch (Alexa suddenly relevant?) by Aaron, and a number of other places, it might be time to take another look at Alexa, with the announcement that they are opening up their data to folks at affordable prices. At least, they appear to be affordable – kind of hard to tell at this point.
Details are here: Alexa Web Search Platform (the original link on the Alexa domain is no longer around). A snippet:
The Alexa Web Search Platform provides public access to the vast web crawl collected by Alexa Internet. Users can search and process billions of documents — even create their own search engines — using Alexa’s search and publication tools.
Seems like it’s time to start taking Alexa more seriously.
