Purpose, Speed & Visibility : Facilitating product discovery & engagement on a e-commerce website

Submitted Apr 29, 2016

Each product on an ecommerce website has an opportunity to sell and market dynamics determines what’s selling and at what speed . This has Merchandising implications for stock re-fill, flash sales, promotions & special events - along with the actions a merchant’s platform team takes in anticipation for such events. By reverse engineering this quantitatively, and tuning the proprietary Search ranking signals, we can meet a Merchant’s business goal both from a discoverability and bottom-line incremental revenue perspective.

This session is about 2 main things –
1. Search & Personalization : Understanding a user’s footprint & quantifying the weblogs to meet two broad goals - facilitating discoverability and driving user engagement .
2. Hypothesis driven engineering - 3 specific problems we solved at Bloomreach - while pushing them upward as proprietary signals in Product design


I will start with defining a user’s intent, web journey and how products sell on an ecommerce website - defining the “discoverability” and “engagement” goals. I will then introduce relevance, recall & performance/engagement based discoverability from a search ranking perspective.
Though the two goals above(discoverability & engagement) look inclusive, I will showcase using the 3 problems, how conventional metrics such as Bounce rate, product view rate, ATC rate, Conversion rate etc. can mask serious challenges that end-users face - thus opening up opportunities about a Merchant can actually address for its users.

Problem # 1 : Understanding lost carts
Data from a merchant with abandoned carts - where we figured out it was a problem with stock-replenishment of popular sizes and people were using carts to “bookmark”. While we do not control/influence a merchandiser‘s inventory - how could we change “the search storefront” (aka the search results page) - to reflect the availability factor that blended the popularity factor - also introducing the supply & demand dynamics at this point.
In the process, we ended up building a clustering solution for mapping sizes across different categories, which then fed into the availability factor.

Problem # 2 : Handling Special events - Mother’s day, Back to school, Halloween & holiday sales , special sports events etc. , Marketplace products & New launches

Using data from the sudden redirect pages that a Merchant’s platform team sets up - to understand a Merchant’s Business goals, quantitatively and then reflecting this in “discoverability” score I introduced before. This means that the evolving intent for these special events now ties to the hot products that merchandizer knows best will sell.
Also, all products are created unequal & by revisiting to a product’s purpose - we can proxy a user’s intent. Since a product only exists in the realm of a “user intent” - bootstrapping some fair impressions is more challenging than it looks.

One goal could be ensuring the new products have some impressions before they starve & set a downward spiral in the ecosystem, but this when also coupled with non-sellable/zombie products that a merchant introduces ahead of launches (eg iphone 6s, Motorola next gen etc.) skews the performance data. eg, some products get a lot of impressions, but do not sell since they are not sellable -this problem will showcase how do we flex the two uber goals of discoverability & engagement for products.

Problem # 3 : Understanding users segments on a website
We can’t fix what we don’t understand is broken. Aside of search, users use very suggestive sort parameters, dynamic filters, paginatation - this problem will showcase data about “intent classification” that helped our search tuning efforts. Brand sensitive vs. price sensitive users are a different breed - and this has search storefront implications, not just for what to show (close substitutes,complementary goods, related but neither substitutes, not complementary goods)- but also on how we measure the intent’s differently. There is no such thing as an average user, afterall.
