Amazon's Alexa API
I have to say that I expected Alexa to be completely irrelevant by now.
I'm glad that it is not; I think that the web archiving part of
Alexa is very important for saving historical information. But
the rest of it just doesn't seem compelling to me. They have
toolbars for IE, Firefox and Chrome, but who needs another toolbar? They say
The world's first toolbar is still the best. The Alexa Toolbar offers
the unique ability to update in real-time to offer you information
about the sites you visit.
I'm not quite sure I understand what that means, but maybe it
gets them a few customers. Something must, because ranking companies like
urltrends and others still include Alexa rank information.
Alexa now offers you programmatic access to its database. The
Alexa Web Information Service is an XML based API that you
can use freely for up to 10,000 requests per month.
One interesting fact gleamed from their FAQS is that they say there
are really only a few million web sites that get any traffic:
Alexa knows about tens of millions of sites; however, the vast majority
of these appear to get no traffic at all. During any given three month
period Alexa sees traffic going to approximately 6 million unique sites.
I would have thought that number was a bit higher. Other parts of
.. Alexa index of the web that, as of August 2004, has over 4 billion URLs.
They have an index of over four billion, but only six million get any
traffic? That seems strange.
One thing you are not going to get from AWIS is an ordered list
of site rankings. They charge for that information. You can
request data about any specific url, and of course that data includes
site rank and incoming links. You can also search by keyword and
