AI Recommendation Engine for E-commerce

Showing every visitor the same products is leaving revenue on the table

Every customer who lands on your store has a different history: what they've bought, what they've browsed, what price range they shop in. Treating them identically means your homepage, product pages, and search results all carry dead weight. We build recommendation systems that use the actual signals in your store data, purchase history, browse behaviour, product attributes, and search queries, to surface the right product to the right customer at the right point in the buying journey.

  • Collaborative filtering on purchase history with real-time personalisation and cold-start handling for new users

  • Content-based recommendations from product attributes and semantic embeddings, works for new items with no purchase history

  • Personalised homepage and category pages with session-aware recency weighting

  • Recommendation analytics tracking click-through rate, add-to-cart rate, and revenue attributed per placement

The problem

Sound familiar?

  • Your homepage shows the same products to every visitor regardless of their purchase or browse history?

  • Upsell widgets on product pages are manually curated, go stale, and are the same for every customer regardless of what they've bought before?

Short answer

RaftLabs builds AI recommendation engines for e-commerce brands: collaborative filtering on purchase history, content-based recommendations from product attributes, personalised homepages and category pages, upsell and cross-sell widgets on product and checkout pages, and search personalisation using embeddings. We integrate with Shopify, WooCommerce, and custom stacks, and give you a recommendation analytics dashboard tracking click-through rate, add-to-cart rate, and attributed revenue per placement. Most recommendation engine projects deliver in 10 to 14 weeks at a fixed cost.

Key takeaways

  • Approximate nearest-neighbour search and precomputed product embeddings mean personalised ranking across 100,000+ SKUs returns in milliseconds regardless of catalogue size.
  • A hybrid model blends content-based signals for low-purchase-count items with collaborative signals for high-purchase-count items, solving the cold-start problem for long-tail products.
  • Embedding-based query understanding handles typos, synonyms, and multi-word intent so search results don't depend on exact keyword matches.
  • A build covering collaborative filtering, personalised homepage, and upsell widgets runs $25,000-$60,000; content-based recommendations and search personalisation bring it to $60,000-$120,000.

Showing every visitor the same products is leaving revenue on the table

The goal isn't novelty for its own sake. It's higher click-through rate on product listings, more items added to cart per session, and a checkout value that reflects what each customer actually wanted to buy.

Capabilities

What we build

  • 01
    Collaborative filtering recommendations

    Matrix factorisation builds a personalised affinity score per customer, updated in real time, with segment-level fallback for cold-start users and A/B testing infrastructure to promote the winning variant.

  • 02
    Content-based recommendations

    Semantic embeddings from product descriptions and attributes let similar items surface even without exact word overlap, indexed for sub-10ms similarity lookups across catalogues with hundreds of thousands of SKUs.

    Built with
    Pinecone · pgvector
  • 03
    Personalised homepage and category pages

    Each visitor sees a product arrangement built from their own history, with session-aware recency weighting boosting items browsed in the last 20 minutes.

  • 04
    Upsell and cross-sell widgets

    "Frequently bought together" and checkout cross-sell widgets are driven by real purchase co-occurrence data, with post-purchase email sequences recommending the next logical product.

  • 05
    Search personalisation

    Results rerank per user by purchase history, with embedding-based query understanding handling typos and synonyms, and zero-results queries redirected to the nearest relevant category.

  • 06
    Recommendation analytics

    A dashboard tracks click-through, add-to-cart rate, and attributed revenue per placement, with statistically-validated A/B test results and segment analysis by customer type.

Frequently asked questions

Collaborative filtering and content-based models both scale well. We use approximate nearest-neighbour search so personalised ranking across 100,000+ SKUs returns in milliseconds, with precomputed and indexed embeddings for constant lookup time. For long-tail products with few purchases, we use a hybrid model blending content-based and collaborative signals.

The core inputs are order history, product catalogue data, and browse events. For Shopify stores, we pull order and catalogue data from the Admin API and instrument browse events via a JavaScript tag. Most stores need 6-12 months of data and a few thousand customers for meaningful collaborative filtering.

Engagement metrics like click-through rate are visible from day one. A statistically significant revenue lift is typically measurable within 4 to 6 weeks of launch, depending on traffic volume. We set up an A/B testing framework as part of the build so you have a clean control group from launch.

A recommendation engine covering collaborative filtering, personalised homepage, and upsell/cross-sell widgets with a Shopify integration typically runs $25,000 to $60,000. Adding content-based recommendations, search personalisation, and a full analytics dashboard typically runs $60,000 to $120,000.
