The Alexa Web Information
Service provides the
following operations:
URL Information
The URL Information operation gives developers direct access to information pertaining to Web pages and sites on the Web that Alexa Internet has gathered through its extensive Web crawl and Web usage analysis. Examples of information that can be accessed are site popularity, related sites, detailed usage/traffic stats, supported character-set/locales, and site contact information. This is most of the data that can be found on the Alexa Web site and in the Alexa toolbar, plus additional information that is being made available for the first time with this release.
Browse Category
The Browse Category operation returns Web pages and sub-categories within a specified category. The returned URLs are filtered through the Alexa traffic data and then ordered by popularity. Using this service a developer can access all the information available at the Open Directory , without the need to download or host the directory database on their own systems.
Web Search
The Web Search operation
is a brand new search
index based on Alexa’s
extensive Web Crawl.
The search query format
is similar to a Google
query and allows up
to 1,000 results per
page. This service
allows developers
or researchers to
create innovative
new search applications.
Crawl Meta
Data
The Crawl Meta Data
operation gives developers
access to metadata
collected in Alexa’s
Web Crawl. For example,
a developer can get
page size, checksum,
total links, link
text, images, frames,
and any Javascript-embedded
URLs for any page
in the crawl.
Web Map
The Web Map operation
gives developers access
to links-in and links-out
information for all
pages in the crawl.
For example, given
an URL as an input,
the service returns
a list of all links-in
and links-out to or
from that URL. This
Web map information
can be used as inputs
to search-engine ranking
algorithms such as
PageRank and HITS,
and for Internet research.
