If you designed an Amazon that was intended for machine consumption you
would make different design choices. A lot of the information there is
useful for human readers but not quite useful for machine. Some of the
information is presented in a particular way to make the page more
appealing, improve perceived response time, etc.

For example, if a book has ten reviews Amazone would only list two on the
first page. But if a machine was reading the information you could cut down
all the fluff (images, tables, redundant links) and provide all ten reviews
in one page that is actually smaller than the one containing two reviews +
fluff. The software would then be able to retrieve all ten reviews in one
HTTP request.

You would also simplify the steps required to make an order. A lot of the
steps were introduced to assist people, but if you automate the process than
a lot of the text/options are no longer necessary and you can cut it down to
a single page.
