The detail page was a few years old and in need for an update to help each business unit (Kindle, paper, Audible...) to succeed. The teams from each unit have gathered together to get to a consensus and a solution.
Most books have multiple formats available on Amazon: Kindle, paperback, hard cover, Audible... and more. Not all formats are treated equally or in the most financially effective way. We needed to adjust the logic to maximize profit.
A few business units such as Audible has established new subscription model, which was not supported by Amazon. We needed to find ways to represent that on Amazon.
The old detail page had very limited space technically for promotional materials, hence leaving miss opportunities to make books more attractive to customers.
There was great deal of big customer data that could serve the books, such as ranking, buying trend, author history... and more. This data could make the page more personalized and converting.
It's clear we want to maximize the revenue for Amazon, but what is most financially meaningful to each business can be different. Therefore reaching alignment on the common set of success metrics and hence strategy was critical.
Since every team had good past research to indicate their user and business opportunities, we could quickly onboard and start coming up with an actionable plan.
The detail page was really complex if we tried to look at it as a whole all the time. Therefore, we broke down components on the page and experiment with them separately so that we could prioritize ones that receive good reaction and come back for consolidation.
After a clear understanding of the most valuable components, we started testing different look and feel, as well as layout that could make all versions of the page cohesive.
While testing styles, we also started testing different interaction types on the components we found valuable. We started mobile-first as there was an overwhelmingly large traffic via that device type.
