Shoppers are becoming more comfortable using AI tools to help them find the right products.
Every time someone searches for a product online—whether it’s on Google, ChatGPT, Amazon, or another marketplace powered by AI—they’re not just scanning a list of results. They’re being shown what the platform’s algorithms think they’ll want to see.
Some products rise to the top. Others never get surfaced at all.
That’s not random. Behind the scenes, artificial intelligence is doing the work of interpreting search terms, evaluating product data, comparing listings, and deciding what to show—and in what order. The ultimate goal is to improve customer satisfaction and conversion rates.
If you learn how to optimize your listings for AI-driven ecommerce, your online store can show up in more product searches and even improve conversion rates.
This article explains how the AI search experience works for product listings. We examine what happens in an AI-driven search that leads to a product recommendation. Learn how generative AI interprets language, retrieves listings, and filters them based on your product data.

And stay tuned for our next blog about AI-powered product discovery to learn how AI tools go from finding relevant products to actually recommending and ranking them above others.
The engine under the hood: how AI search works
Let’s say someone searches for a “lightweight trail running shoe” on Google Shopping or a voice assistant. Somewhere in a massive product index, there’s a match—or at least a shortlist of contenders. But the shopper never sees all of them. Only a few products rise to the top. So what actually determines which one shows up?
To understand that, it helps to start with the raw material AI is working with: the product listing itself.
AI search platforms see all the structured and unstructured product data in a listing. This is not a trail running shoe, but you get it.
What artificial intelligence sees in a product listing
Product data is the backbone of ecommerce, so of course it’s very influential in AI-powered search. It doesn’t matter if you’re selling products through an online store with a platform like BigCommerce or Shopify, on social media channels like TikTok, or on marketplaces like Amazon and Walmart—the quality of your product listings has a major impact on your conversion rates and the customer experience.
If you want to optimize your listings, you need to understand how AI search algorithms analyze product data in near real-time to determine relevance.
Every product listing is made up of two main types of data:
- Structured data is the technical stuff—catalog fields like color, size, material, brand, gender, price, and availability. This is what gets mapped to filters and dropdowns. It’s formatted to be read by machines.
- Unstructured data includes free text like the description, reviews, or even captions in visual content. It’s messy, but rich with context. This is where shoppers (and AI) get a sense of what the product is.
Product titles occupy a gray area between structured and unstructured data. They are technically structured data, required in catalogs, and expected to follow best practices (brand + product type + key attributes). But they are also analyzed by AI to gather meaning and intent, and to determine relevance for search results.
In our example, a product listing could look like this:
- Title: “Men’s Lightweight Trail Running Shoes – Breathable Mesh”
- Color: Navy
- Category: Footwear > Athletic > Running
- Description: “Designed for off-road running, with a flexible sole and moisture-wicking upper.”
- Tags: trail, outdoor, running, lightweight, breathable
This is some of the information that AI search engines use to determine whether the product matches a user’s intent, but not all of it. Let’s continue.

How AI uses Natural Language Processing to interpret a product search
AI doesn’t just look for keywords anymore. It uses Natural Language Processing (NLP) to understand what a shopper means, to surface relevant products that might not match your search verbatim.
NLP is what allows AI-powered search tools to recognize that “trail running shoe” is a type of footwear, that “lightweight” refers to comfort or material, and that “breathable” implies performance features. It does this by breaking down language into mathematical representations.
Key terms defined:
Natural Language Processing (NLP)
The field of AI that enables machines to understand and interpret human language. In ecommerce, NLP helps AI systems understand shopper queries like “shoes for muddy trails” and match them to listings that mention “waterproof trail running shoes,” even if the words don’t exactly align.
- Analogy: Think of NLP as teaching a machine how people talk, so it can make smart connections between related words and ideas.
Vectors and embeddings: the coordinates of meaning
Here’s where things get more technical, but you don’t have to be an expert to get the concept.
Imagine a giant universe of language, represented by a multidimensional map. Every word or phrase is charted onto the map of the universe, so that similar concepts are clustered closer together. Of course, this map is not a literal thing, but it’s helpful for illustrating the general idea.
In order to navigate the map, AI uses a process called embedding to convert user search queries (e.g., “what’s a good lightweight trail running shoe?”) and online product listings into sets of coordinates on the map.
These coordinates are called vectors. These vectors allow the AI to mathematically compare how similar two concepts are. The closer the vectors are in space, the more semantically similar they are, which increases the likelihood that the product will be shown in the results of a search.
On the giant language map…
- “Sneakers” and “running shoes” might land in the same neighborhood.
- “Boots” and “heels” might be nearby, but in a different cluster.
- “Navy” and “dark blue” could be close—or not—depending on how the AI was trained.
So when a shopper types “lightweight trail running shoe,” AI models convert that phrase into a vector and look for product listings with vectors that land close by.
This is known as semantic retrieval. It allows AI to surface products that don’t contain the exact words in the query, but still match the shopper’s intent. Basically, it’s the process of making connections or deriving meaning from words.
Machine learning has enabled AI search tools like ChatGPT, Perplexity, Gemini, and Google search using AI mode to create a better user experience. Even if shoppers do not hit all the “keywords” that you have in your product listing, AI uses a combination of customer preferences and natural language processing to provide personalized recommendations and display relevant products.
Speaking of keywords, keep reading to see how AI-generated search actually depends on “tokens” rather than the keywords of traditional search.
Key terms defined:
High-dimensional space
The “map” where AI places vectors. Instead of just using a few dimensions like height, width, and depth, this map has hundreds of dimensions, each representing a different nuance of meaning—like tone, function, material, or category.
- Analogy: Imagine organizing shoes not just by color and size, but also by breathability, season, trendiness, price, brand tone, and 100 other traits—all at once.
Semantic retrieval
A method where AI retrieves products based on meaning, not just exact keywords. It uses vector comparisons to return listings that are close in intent—even if the wording is different.
- Example: A product search for “eco-friendly laptop case” could retrieve products labeled “recycled neoprene tech sleeve.”
Do keywords still matter for AI search?
If you’re familiar with traditional search and SEO, you might be wondering if keywords play a role in how AI finds products.
Even though AI can retrieve relevant results without exact or even partial keyword matches, exact matches still play a role—especially in highly competitive product categories. However, in AI search, the concept of a “keyword” is loosely replaced by a “token” to reach the next level of product discovery.
Tokens are the individual words or components that AI extracts from a search query or a product listing. Think of them as the building blocks AI uses to determine meaning. When a product listing shares tokens with a shopper’s query—like “trail,” “running,” or “lightweight”—that overlap can increase its relevance score.
For example, if one product title says “lightweight trail shoe” and another says “performance off-road trainer,” both may be semantically similar, but the first is more likely to rank higher because it shares more tokens with the query.
That said, language consistency matters. Covering all your bases with different tokens can backfire. If your listing uses “navy” in one field and “blue” in another without clarification, or mixes terms like “trainer” and “running shoe” without reinforcement, it can dilute the match.
What does reinforcement mean in this context?
Reinforcement means supporting or clarifying a term by pairing it with a more commonly used or semantically aligned phrase to help AI make the correct association.
In this case, reinforcement helps AI understand that two different terms (like “trainer” and “running shoe”) are referring to the same or similar concept, even if they don’t share the same tokens.
Example of reinforcement in action:
Without reinforcement
Title: “Men’s Performance Trainer”
Description: “Built for off-road grip and speed.”
AI may be unsure if “trainer” = “running shoe,” especially if the term “running” is never used.
With reinforcement
Title: “Men’s Performance Trainer (Running Shoe)”
Description: “This running shoe offers the support of a classic gym trainer with trail-ready grip.”
Now the listing uses both terms, reinforcing the idea that they’re related. This improves AI understanding and semantic matching.
Remember that AI tokenizes all the text in your product listing, not just the title. Descriptions, bullet points, and even alt text contribute to the overall signal. The clearer and more consistent your language, the easier it is for AI to recognize and recommend your product.

How AI finds products FAQs
How do datasets impact AI’s ability to find relevant products?
High-quality datasets are the foundation of accurate and relevant AI-powered product discovery. Every product listing feeds into a larger dataset that trains and informs AI models. These datasets can include structured fields like color, size, and brand, as well as unstructured elements like customer reviews and image captions. The broader and more consistent the dataset, the better the AI can understand what a product is—and when it’s relevant to a query.
As AI interprets product information, it compares these datasets across thousands (or millions) of listings to find patterns and matches. In short, great datasets make AI more precise in surfacing the right products.
How does AI handle new products that don’t have much data yet?
New products often lack the historical data or customer interaction signals that help AI determine relevance. However, AI compensates for this by analyzing available structured and unstructured data in the product listing. Using natural language processing and semantic retrieval, AI models can still position new products accurately—especially if the listing includes reinforced terms and tokens that align with popular search queries.
How do APIs streamline product discovery with AI tools?
APIs play a crucial role in helping ecommerce platforms and marketplaces share product information with AI tools in real-time. By exposing structured data—such as inventory levels, pricing, or attributes—via API endpoints, retailers can ensure their product feeds stay updated and consistent across multiple discovery channels. This consistency is key for AI systems to retrieve and match relevant listings.
Can chatbots help customers find the right products with AI?
Yes—AI-powered chatbots are becoming an increasingly common interface for product discovery. Instead of relying on exact keywords, modern chatbots use natural language processing to interpret a shopper’s intent and query product catalogs accordingly. This makes them highly effective for guiding users to relevant products, even when the customer doesn’t know exactly what they’re looking for.
Chatbots often tap into the same product datasets and semantic search capabilities discussed in this blog. They can also use user context—like past behavior or preferences—to refine their suggestions.
How does visual search fit into AI-driven product discovery?
Visual search allows shoppers to upload or capture an image and receive product matches based on visual similarity—bypassing the need for typed queries. AI interprets the visual characteristics of the image (such as color, shape, texture, or patterns) and converts them into vectors, just like it does with text. These visual vectors are then compared against product listings that include image data, helping the system find semantically similar products.
