Before & After AI

What this workflow looks like before and after transformation

Before

Product recommendations rely on simple rules: "customers who bought X also bought Y" or popularity-based lists. Personalisation is limited to basic segments (new vs. returning, geography). Recommendation click-through rate sits at 2-4%. The same recommendations are shown to very different customers, missing individual preferences.

After

AI learns individual customer preferences from browsing, purchase, and interaction data. Real-time personalisation adapts recommendations as customers browse. Contextual signals (time, device, season) further refine suggestions. Recommendation CTR increases to 8-15%, driving measurable revenue lift.

Implementation

Step-by-Step Guide

Follow these steps to implement this AI workflow

1

Collect & Prepare Interaction Data

3 weeks

Instrument your platform to capture: product views, searches, add-to-cart, purchases, ratings, and dwell time. Build a unified customer profile combining behavioural data with demographic and transactional history. Address cold-start for new users and new products.

2

Build Recommendation Models

6 weeks

Implement multiple recommendation approaches: collaborative filtering (users with similar behaviour), content-based filtering (similar product attributes), and hybrid models. Use deep learning embeddings for complex pattern recognition. Build A/B testing framework for model comparison.

3

Build Real-Time Serving Infrastructure

3 weeks

Deploy recommendation API capable of sub-100ms response times. Implement feature store for real-time customer context. Build caching layer for frequently requested recommendations. Design fallback strategies for cold-start scenarios.

4

Integrate Across Touchpoints

3 weeks

Add recommendations to product pages, homepage, search results, email campaigns, and app push notifications. Design UI components that maximise recommendation visibility and click-through. Implement business rules (inventory, margin, promotion) as recommendation filters.

5

Optimise & Personalise

Ongoing

Run continuous A/B tests on recommendation algorithms, placement, and UI. Implement contextual bandits for real-time optimisation. Add diversity and serendipity controls to avoid filter bubbles. Track revenue attribution to recommendations.

Frequently Asked Questions

Basic collaborative filtering needs at least 1,000 users with 5+ interactions each. Content-based recommendations can work immediately using product attributes. For new platforms, start with popularity and content-based approaches, then layer in collaborative filtering as interaction data accumulates. You'll see meaningful personalisation within 2-3 months of data collection.

For new users: start with popular items, trending products, and contextual signals (geography, device, referral source). As they interact, quickly learn preferences. For new products: use content-based similarity to existing products. Most modern recommendation systems handle cold-start gracefully through hybrid approaches.
