Why were we doing this?


Why were we doing this?

Why were we doing this?

Customer feedback and usage data made it clear that our existing search experience was falling short. The key issues we identified were:
  • Increase in Bounce Rate: There was an exponential increase in Bounce Rate on Engagement Metrics for Search Functionality
  • Limited Product Discovery: The existing search returned a narrow set of results, impacting both customer satisfaction and conversion.
  • Low Relevance: Users frequently encountered results that didn’t match their intent, leading to friction and drop-offs.
  • Desktop Underperformance: Desktop usage remained strong, but the experience lacked sophisticated navigation tools that could improve engagement and retention

Insights

We gathered datapoints through User Journey, User Feedback and SWOT Analysis as well as other quantitative and qualitative analysis to set our goals. Our major insights were:

🔷 Broken & Inaccurate Search Undermines User Trust

📌 Users frequently encounter zero results for relevant queries (e.g., “yogurt,” “bagels”) due to poor synonym recognition and lack of typo tolerance.

🔷 Search Experience Lacks Personalization & Context

📌 Static suggestions and disconnect between user terms vs. site terms lead to drop-offs. There's a need for dynamic, personalized, and behavior-aware search suggestions

🔷 Search is Central to the Entire Purchase Journey

📌 Search is the entry point for discovery and impacts all downstream stages: evaluation, carting, payment, and retention. Failures here compound across the funnel

Integrating ML Powered Search UX

Integrating ML Powered Search UX

✨ Why ML was necessary

Traditional rule-based search couldn’t keep up with evolving user behavior, ambiguous queries, and personalization needs. Machine learning enabled the system to understand intent, correct typos, and learn from user interactions — turning search from a static lookup tool into a dynamic, self-optimizing discovery engine


We picked models that gave the most bang for our buck — the ones that made search smarter without slowing things down or costing too much to maintain

    Provides real-time learning from user feedback (clicks, skips).


  • Trade-offs:

    • Doesn’t model multi-step interactions

    • Needs careful exploration vs. exploitation balance

    • Requires robust logging & reward tuning


  • Impact:

    • Before ML: Same search suggestions shown to everyone regardless of behavior

    • After ML: Learns which suggestions work best for each user in real-time

Recommendation System: Hybrid Recommendations
(Collaborative Filtering + Content-Based Filtering)

Models: Matrix Factorization, Word2Vec
Purpose: Personalized Recommendations

  • Why Selected:
    To combine user interaction patterns (Collaborative Filtering) with semantic product similarity (Word2Vec) for more relevant and diverse recommendations.


  • Trade-offs:

    • Requires regular retraining to stay relevant

    • Cold start problem for new users or items

    • Balancing signal weight between CF and content-based requires tuning

  • Trade-offs:

    • Embeddings require offline preprocessing & storage

    • Slower real-time similarity lookup

    • Memory-intensive


  • Impact:

    • Before ML: Typing “home workout gear” only returned results containing that exact phrase

    • After ML: Matched related terms like “dumbbells,” “resistance bands,” and “yoga mats” using embeddings

Model: BERT / DistilBERT
Purpose: Intent Detection

  • Why Selected:
    It understands the meaning behind ambiguous or multi-intent queries like “apple” or “running”


  • Trade-offs:

    • High latency unless distilled

    • Requires GPU resources for real-time inference

    • Needs fine-tuning on domain-specific data


  • Impact:

    • Before ML: Typing “apple” showed a generic list of fruits and electronics mixed together

Data Analysis


User Journey

Data Analysis

To make the feature enhancement more effective, using my HCI knowledge, I decided to frame effectiveness as “how much does a user learn from using the product?” and “how do they react in unfamiliar problem situations?” I analyzed the user journey to see how much information the users can potentially retain and how well they react to new situations. I used this data to establish a benchmark for future iterations of the product

Final Thoughts

Search is deceptively complex. While it might appear to be a straightforward feature, it quickly reveals its depth when approached with the goal of delivering real user and business value. Early in the project, I underestimated its complexity—but through hands-on discovery, user research, and performance analysis, I came to appreciate just how nuanced user intent, behavior, and expectations around search can be.

One of the key learnings from this initiative was the importance of data-driven decision making. Users interact with search in diverse ways, and qualitative assumptions alone would not have uncovered the underlying friction points. By leveraging real user data, we were able to inform every iteration with confidence and precision.

This project also reinforced the critical role of cross-functional collaboration. Working closely with UX designers, engineers, and analysts in a small but focused team environment taught me that strong communication and alignment are not just helpful—they are essential for both delivering impactful outcomes and fostering a healthy, productive team dynamic.

The Stop & Shop Search Typeahead Redesign stands as a strong example of how thoughtful product management—grounded in user insights, aligned to business metrics, and executed through collaborative teamwork—can turn a core user experience into a strategic growth lever. The improvements we made not only enhanced the user journey across devices but also laid the groundwork for continued innovation in how customers discover products.
