Reframing the problem
Reframing the opportunity
76% of neighbors said community shaped their purchases, but that word-of-mouth was buried in conversations. Removing the legacy tagging flows dropped engagement 42%, to over 200 daily interactions on a platform serving 1 in 3 US households.
Framed the work as two jobs to be done which became the filter for decisions:
Neighbor: help customers show support for local businesses so they thrive.
Business: help businesses prove their reputation so they grow new customers.
Key Design Decisions
01
Surface word-of-mouth content
Make user feedback visible and discoverable to build customer trust with local businesses.
02
Optimize for actions
Make it easy for customers to find and share the businesses they love
03
Reduce participation friction
Let users discover, save, and share businesses with ease through familiar patterns

OLD LEGACY TAGGING FLOW & LEGACY PAGES

Product & Design Strategy
Four guiding pillars that became the north star for every tradeoff and stakeholder conversation.
01
Fix broken taxonomies
Repair recommendation pathways that became broken after system changes
02
Improve core usability
Make it intuitive for users to find, evaluate, and take action on businesses.
03
Provide path to shares
Create more natural opportunitiies to save and share businesses using universal interaction patterns
04
Improve performance
Address the latency and reliability issues that blocked engagement.

Redesigned

Auto-tagging businesses in recommendations
Our key metric was to increase engagement, growth, and raise awareness around businesses. Research showed that high engagement occurs in comments when users request services. I partnered with the machine learning team to identify posts seeking services which then enabled the system to detect and auto-tag mentioned businesses on classified posts.

Note: the +84% reflects in-comment engagement including business owner self-mentions, an edge case the ML classifier had not modeled. Total recommendations lift was +15%. I scoped a fix with the vitality team to filter self-mentions before transitioning off.
