Personalized Product Recommendations Via ChatGPT

Introduction

In the world of digital culinary content, delivering relevant, tailored experiences to users can significantly enhance engagement. For one of our clients, a prominent online cooking recipe platform, the goal was to create personalized search experiences that would adapt to each user’s unique tastes and preferences. By leveraging AI to personalize search based on user interactions, the client aimed to create a more dynamic, engaging platform for users with diverse culinary interests.

About the Client
Our client is a leading cooking recipe website with an extensive library of recipes and culinary resources. Serving a global audience of food enthusiasts, the platform provides a range of recipes spanning diverse cuisines, flavors, and dietary preferences. The client’s focus is on offering a tailored experience that reflects each user’s unique tastes, making it easy to find relevant recipes based on personal preferences and past engagement.

Challenge
With over 10,000 recipes on the site, delivering relevant content posed a significant challenge. Users often sought highly specific recipe recommendations based on their favorite ingredients or past interactions, such as saved or frequently clicked recipes. Traditional keyword-based searches couldn’t provide the level of personalization the client wanted to achieve. They required a solution capable of understanding user preferences at a deeper level to suggest recipes that aligned with their tastes and culinary habits.

Solution
To address this need, we developed an AI-powered personalization solution, implemented through several key steps:

1. User Profiling Based on Engagement: By analyzing past interactions—such as clicks, saved recipes, and frequently searched ingredients—we created unique profiles for each user. These profiles provided insights into individual preferences, highlighting preferred flavors, ingredients, and cuisines.
2. Embedding Product Data and Metadata: We created embeddings for each recipe and its metadata (title, description, and category) to enable semantic understanding of the content. This allowed for more accurate retrieval of recipes that matched user interests, even if their search terms didn’t align perfectly with traditional keywords.
3. Using Retrieval-Augmented Generation (RAG): Through RAG, the system matched user queries with relevant recipes based on their profile. This technique allowed for real-time retrieval of recipes that best matched each user’s current and past interests, improving relevance.
4. Ranking and Relevance Explanation with ChatGPT: Leveraging LLMs, we ranked recipes by relevance and generated explanations for each suggestion. This added layer of transparency helped users understand why each recipe was recommended, further enriching the personalized search experience.

Results
The personalized search solution significantly enhanced the user experience on the client’s platform. Key outcomes included:

• Improved Engagement: Users spent more time on the site as the personalized search helped them discover new recipes more suited to their tastes.
• Higher Conversion Rates: The enhanced relevance of recommendations led to an increase in recipe saves and shares, supporting a more engaged user base.
• Increased Retention: By providing a unique, tailored experience, the client saw improved user retention rates as visitors found more value in the platform’s recommendations over time.
