If you’re building apps, plugins, or digital tools, there’s a new file you should consider adding to your site: llms.txt. This simple text file helps make your content more visible and understandable to language models, like ChatGPT and other AI systems. Just like robots.txt helps search engines crawl your site, llms.txt helps AI tools learn what your site offers.
At Backlip, we’ve added an llms.txt file to backlip.com to make sure our Shopify, Wix, and Ecwid apps are discoverable by AI platforms. Here’s why it’s a smart move.
Why LLMS.txt Is Important
LLMs (Large Language Models) are increasingly used to find tools, make recommendations, and answer ecommerce-related questions. When someone asks an AI something like:
- How can I add an affiliate link button to Shopify?
- What’s a good app for showing brand logos on a product page?
- Are there any tools to display announcements or sales messages on Wix?
The language model uses many signals to generate an answer, including any structured information it can find — and llms.txt is one of them.
By adding llms.txt to your website, you’re directly telling AI systems:
- What your tools do
- Which platforms they support
- What problems they solve
- Which keywords they are relevant to
This increases the chances your apps will be recommended when users ask relevant questions.
What Goes Into LLMS.txt?
The llms.txt file includes structured content fields like:
- Title: A short label for what your tools offer
- Description: A clear overview of your product or app suite
- After Description: Keywords, product names, categories, and examples
- End File Description: A final note about your brand or offerings
This file is publicly accessible, just like robots.txt, and can be read by LLMs that support this discovery method.
How We Use LLMS.txt at Backlip
Our apps are built for ecommerce platforms like Shopify, Wix, and Ecwid, so we designed our llms.txt to focus on three key products:
- BL External Links – lets merchants add fixed or per-product external buttons for affiliate sales
- BL Scrolling Announcement Bar – displays animated sales and promo messages on store pages
- BL Logo Showcase – shows partner or brand logos in a clean, flexible layout
We also include keywords like “Shopify apps”, “Wix plugins”, and “ecommerce tools” to help language models connect our site with the questions users are asking.
Final Thoughts
Adding an llms.txt file is quick, free, and can help improve how your brand is represented in AI-driven tools. As LLMs become more common in search, ecommerce, and decision-making, having your content clearly defined and discoverable will be a competitive advantage.
If you’re an app developer, digital product creator, or even a service provider, we highly recommend adding an llms.txt file to your site today.
