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.
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.
Browse
Category
The
Browse
Category
operation
allows
developers
to access
all the

Directory
without
the need
to download
or host
the directory
database
on their
own systems.
This
service
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.
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
and 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.
Crawl
Meta
Data

Crawl
Meta
Data
operation
gives
developers
access
to metadata
collected
in Alexa's
Web Crawl.
For example,
a developer
can get
pages
size,
checksum,
total
links,
link
text,
images,
frames,
and anyu
Javascript-embedded
URLs
for any
page
in the
crawl.
