E-commerce

A product recommendation can help a customer choose faster, but it becomes annoying if it ignores the context: previously viewed product, size, budget, usage, cart or previous purchase. The customer wants relevant help, not an automatic window display.
The chatbot must use the available context with caution, explain why it is suggesting a product and acknowledge the limitations when compatibility, size or a preference is not certain.
This guide shows how to make contextual product recommendations more useful and respectful.
Summary
Why does context change the quality of a recommendation?
A customer looking at a product page, adding an item to their cart, or returning after a purchase is not asking the same question as a visitor who is just discovering the brand. The context allows help to be adapted to the actual moment of decision.
But this context must be used to serve the customer's needs, not to push just any product. A poorly targeted recommendation reduces trust.
The right recommendation explains why it is relevant for this customer, at this exact moment.

Which information to use?
The bot can use the viewed page, the products in the cart, the filters, the chosen sizes, the country, the expressed budget, accessible past purchases, and the preferences provided in the conversation.
It must distinguish between information confirmed by the customer and a simple hypothesis. A purchase history can help, but it does not replace a question about current usage.
How should the recommendation be formulated?
The response must explain the link between need and product: “this model is suitable if you are looking for a lighter version”, “this accessory is compatible with the specified reference” or “this size is the closest to your measurements”.
The chatbot should avoid vague phrases like “popular product” if they do not answer the customer's question.
How do I manage privacy?
If the bot relies on a history or a customer account, it must do so in accordance with the confidentiality rules and available permissions. It must not reveal sensitive information in an unverified conversation.
The customer must be able to understand that the recommendation comes from the visible context, the shopping cart, or a preference they have shared.
How to avoid compatibility errors?
For accessories, sizes, parts, consumables, or technical products, the chatbot must verify the model, version, dimension, and catalog source before recommending.
If compatibility is only probable, it must say so and offer human verification when the mistake would be costly to the customer.
Which flow to follow?
The flow must connect the recommendation with the actual need.
Identify the relevant page, cart, need, usage, budget, country, size, or model.
Verify available sources: catalog, stock, compatibility, authorized history, and preferences.
Offer few options, providing a clear reason for each recommendation.
Qualify limits: uncertain sizing, unconfirmed compatibility, or fluctuating stock.
Escalate expensive purchases, sensitive compatibility, private data, and disputed recommendations.
Which messages should be used?
To explain: "I am proposing this model because it corresponds to the usage you have just described."
For context: "I am basing this on the item in your cart and the information visible here."
For limitation: "I cannot confirm this compatibility without the exact reference of your product."
When to transfer?
Transfer is necessary if the recommendation involves costly compatibility, a warranty, personal data, a B2B order, a medical product, or an unconfirmed commercial promise.
The bot must transmit the need, viewed products, cart, criteria, consulted source, uncertainty, and customer expectation.
Which KPIs should be monitored?
Track clicks on recommendations, assisted conversions, post-recommendation returns, disputed compatibilities, satisfaction, drop-offs, and preference correction requests.
This data shows if the recommendations truly help in choosing the right product.
Which mistakes should be avoided?
Avoid recommending too many options, ignoring the budget, over-relying on history, promising compatibility without confirmation, or pushing an out-of-stock product.
The recommendation should reduce uncertainty, not add commercial pressure.
How can Qstomy help?
Qstomy can connect the chatbot to the catalog, cart, authorized history, support conversations, privacy rules, rights requests, product recommendations, and escalation procedures to respond clearly, and then transfer sensitive cases with an actionable summary.
The chatbot helps the customer move forward without inventing compatibility, a preference, a data rule, a history, or a recommendation that has yet to be confirmed by a reliable and authorized source.
