OpenCart LLMs TXT Generator Extension- Complete User Guide

The OpenCart LLMs TXT Generator Plugin is a powerful extension designed to generate an llms.txt file for your store. This file contains well-structured information about the store catalogue, including products, categories, and CMS pages, making it easier for AI platforms to understand and access your content.

Today, customers increasingly rely on AI-powered platforms such as ChatGPT, Gemini, DeepSeek, Perplexity, and Claude to search for products and get recommendations. As AI-driven searches continue to grow, having your products recommended by these platforms can significantly improve your store’s visibility and reach.

To address this, Knowband has developed the OpenCart LLMs TXT Generator Plugin, which enables AI platforms to discover, understand, and recommend your products more effectively.

The llms.txt file generated by the Knowband OpenCart LLMs TXT Generator allows AI crawlers and AI answer engines to access store content in an organised and structured format. By placing this file on your server, your store becomes compatible with modern AI search engines and AI product recommendation models such as ChatGPT, DeepSeek, Gemini, Perplexity, and Claude.

Using this AI product recommendation extension for OpenCart improves AI product discovery, supports accurate AI-generated answers, and ensures that your store content is correctly identified and referenced when users search for product- or store-related information on AI-driven platforms.

This crawler setting in Opencart LLMS TXT Generator allows the store owners to manage the AI model’s bots like GPTbot, Google Extended Gemini Bot, DeepSeek and many more

3.3 Content Filtering

The Content Filtering functionality enables store administrators to decide exactly which store data is included in the generated llms.txt file. This gives you full control over the information shared with AI crawlers and answer engines, ensuring that only meaningful and approved content is exposed while private or irrelevant data remains excluded.

1. Shop Context

The Shop Context setting is designed for OpenCart installations with multiple stores. It allows administrators to select a specific store and generate a dedicated llms.txt file for that shop. Each store can have its own configuration, ensuring accurate and store-specific content generation.

 

2. Product Details

The Product Details filter determines which products appear in the llms.txt file. Store owners may include all products or restrict the selection based on business needs. Options include adding only active products, featured items, or manually selected products, while excluding others from being shared.

3. Category Details

The Category Details filter helps manage category-level content. Administrators can choose which categories should be included, allowing inactive or unnecessary categories to be excluded. This keeps the file well-structured and focused on relevant store data.

4. CMS Pages

The CMS Pages filtering option allows you to control which CMS pages are included in the CMS llms.txt file. This is useful for preventing internal, draft, or temporary pages from being shared, while still making essential pages such as policies and informational content available to AI platforms.

 

3.4 Customization

The Customization features of the OpenCart LLMs.txt Generator allow store owners to add additional context to the generated llms.txt files. These options help enhance product, category, and CMS information with helpful notes, improving how AI crawlers interpret your store content.

 

1. File Boundaries Customisation

The File Boundaries option allows you to insert custom text at the beginning and end of the llms.txt file. This can be used to add general instructions, notes, or explanations without altering the core store data, helping crawlers understand the file structure more clearly.

2. Store Description

The Store Description customisation lets you add content before and after the store description section in the llms.txt file. This helps define your store’s purpose, key offerings, or any special instructions, making it easier for AI-driven platforms to generate accurate responses related to your business.

3. Category Section Customisation

With Category Section Customisation, store owners can add explanatory text before and after the categories section. This is useful for clarifying category organization, naming patterns, or relationships, allowing crawlers to interpret category data more accurately.

4. Product Section Customisation

The Product Section Customisation feature allows you to include additional notes before and after the product details section. These notes can provide general product-related guidelines or context without modifying the actual product information, improving AI understanding and recommendations.

 

5. CMS Pages Section Customisation

The CMS Pages Section Customisation option enables administrators to add contextual notes around the CMS pages section. Since CMS pages often contain key information such as policies, FAQs, and shipping details, this added context helps AI systems better interpret non-product content.
