Most retailers continue to view search as a basic function. The top performing e-commerce brands are starting to see it as a major source of revenue. Search visitors account for up to 60% of online retail revenue, yet many stores still rely on outdated architectures that don’t fully grasp customer intent. The result is irrelevant search results, zero-result pages, abandoned shopping carts – and waning consumer trust.

The future of AI in e-commerce is moving toward sparse retrieval models like SPLADE.

Why? Because sparse embeddings take the best aspects of traditional keyword search and modern neural search – and avoid the worst parts. Dense embeddings often obscure essential attributes:

256GB vs 128GB

Black vs Midnight Black

Running shoes vs running socks

BM25, meanwhile, completely misses customer intent – unless the exact phrase is used. Sparse embeddings create a more balanced approach. They understand relationships between concepts while also maintaining the precise relevance of vocabulary. Even more importantly, they remain very interpretable. Merchandising teams can really get why one product shows up above another product in results.

This level of transparency is key beyond just improving retail performance. With frameworks like AI TRiSM and regulations like the EU AI Act getting more attention, explainable AI systems are becoming operational requirements – not just optional features. 

The most significant shift is strategic:

Search is no longer just a data retrieval tool. It’s becoming the core base for commerce systems that can think, personalize, suggest, and even automate customer journeys. Retailers who update their search today aren’t just making their website better looking. They’re actually setting up the retrieval foundation for the self-driving commerce ecosystem emerging over the next decade itself. That’s no small optimization. It can even move the right product from page two to the top result, greatly affecting click-through rates and completed checkouts all by itself. As AI in e-commerce evolves, search is becoming the highest return-on-investment infrastructure layer in digital retail. The brands putting their money into intelligent retrieval today will outdo competitors still relying on outdated keyword systems tomorrow.
