Find out what products are hot on either side of the pond with Amazon locale-based queries.
Why are
some albums more popular in the U.K.
than in the U.S.? This hack can’t answer that question, but it can
point out what the differences are. It uses two features of AWS
requests, sort and locale, to
generate parallel lists of bestsellers by artist.
This ASP code makes two ArtistSearch requests.
Both are sorted by sales rank, and the only difference between the
two is the setting for the locale. In the first
query, locale is left blank, for the default
Amazon.com store. The other query sets the locale
to uk, searching Amazon.co.uk. Create a file
called
us_vs_uk.asp
with the following
code:
<html>
<head>
<title>International Sales</title>
</head>
<body>

Dim arUKResults(10,4)

AssociatesID = "insert associate tag"
