There’s a file that a small but growing number of websites around the world have quietly added to their domain. It’s called llms.txt. Most Malaysian businesses have never heard of it.
That gap — between the businesses that know about it and the ones that don’t — is exactly where AI search visibility is being won and lost right now.
This article explains what llms.txt is, why it exists, and whether your Malaysian website needs one.
Some Background: How AI Tools Read the Web
When an AI tool like ChatGPT, Perplexity, or Claude wants to understand a website, it sends a bot to crawl the pages. That bot reads the text, processes the structure, and builds an understanding of what the site contains.
The problem is that most websites are built for human eyes, not AI comprehension. They contain navigation menus, cookie banners, footer links, JavaScript-heavy components, and marketing copy that is difficult for AI to parse meaningfully. The actual useful content — what the business does, who they serve, what they offer — is often buried inside all of this noise.
AI crawlers do their best. But “their best” on a poorly structured website still results in a vague, incomplete, or inaccurate understanding of your business.
llms.txt was created to solve this problem.
What is llms.txt?
llms.txt is a plain text file that you place at the root of your website — accessible at yourdomain.com/llms.txt — that is written specifically for AI tools to read.
It was proposed in 2024 by Jeremy Howard, a prominent AI researcher, as a standard way for website owners to communicate clearly with large language models (LLMs) about the content and structure of their site. The full specification and examples are published at llmstxt.org.
Think of it as a guided tour of your website, written in clean, unambiguous language that AI tools can read and process without having to wade through all the visual and structural complexity of your actual web pages.
A basic llms.txt file might describe:
- What your business does
- Who your customers are
- What your key pages contain and where to find them
- Which content is most important
- Any context that would help AI understand your business accurately
How is llms.txt Different from robots.txt?
You may already know about robots.txt — the file that tells search engine crawlers which pages they are and aren’t allowed to visit.
llms.txt is different in purpose. While robots.txt controls access, llms.txt provides context.
| robots.txt | llms.txt | |
|---|---|---|
| Purpose | Control crawler access | Guide AI comprehension |
| Audience | All crawlers | AI / LLM tools specifically |
| Content | Allow/disallow rules | Business description and content map |
| Mandatory | Best practice | Emerging standard |
| Impact on AI | Indirect | Direct |
You need both. robots.txt makes sure AI bots can access your site. llms.txt makes sure they understand it correctly once they do.
Why Does This Matter for Malaysian Businesses?
Here is the practical impact.
When an AI tool crawls your website without an llms.txt file, it pieces together an understanding of your business from whatever it can parse — your page titles, headings, body copy, meta descriptions. This works reasonably well for simple, well-structured websites.
But for most Malaysian business websites — which tend to be built around visual design rather than content clarity — the AI’s resulting understanding is often incomplete or imprecise.
A logistics company in Shah Alam might get described as a “supply chain services provider” when they actually specialise in cold chain logistics for the food industry. A legal firm in KL might be understood as a general practice when they focus specifically on employment law. A dental clinic in Subang might be categorised broadly when they are one of the few clinics in the area offering Invisalign.
These imprecisions cost recommendations. When someone asks AI for a cold chain logistics company in Selangor, the logistics firm with an unclear online presence doesn’t surface — even if they’re the best option.
An llms.txt file lets you correct this. You tell AI tools exactly what you do, in your own words, clearly and unambiguously.
What Does a Good llms.txt File Look Like?
There is no single enforced standard yet — llms.txt is still evolving. But the most widely adopted format follows this structure:
# Business Name
> One-sentence description of what the business does and who it serves.
## About
A short paragraph describing the business — its history, location, specialisation, and key differentiators.
## Services
- Service 1: brief description
- Service 2: brief description
- Service 3: brief description

Does Every Malaysian Website Need One?
Not every website will see the same benefit — but for most Malaysian businesses with any interest in AI search visibility, the answer is yes.
High priority if:
- Your website has complex navigation or JavaScript-heavy design
- Your business has a specific niche or specialisation that generic crawling might miss
- You operate in a competitive local service category (F&B, healthcare, legal, education, professional services)
- You want to be found for specific queries that require nuanced understanding of what you do
Lower priority if:
- Your website is a simple, text-heavy site that AI can already parse clearly
- You operate in a very broad category with no meaningful differentiation to communicate
- Your primary customers don’t use AI search tools
For most Malaysian SMEs, the file takes less than an hour to write and can meaningfully improve how AI tools understand and describe your business. The effort-to-impact ratio is high.
How to Add llms.txt to Your Website
- Create a plain text file named
llms.txt - Write your business description following the format above — be specific, clear, and accurate
- Upload the file to the root directory of your website so it is accessible at
yourdomain.com/llms.txt - Test it by visiting
yourdomain.com/llms.txtin your browser — you should see plain text
If you’re on WordPress, you can add it via your file manager or FTP. If you’re on Shopify, you’ll need to add it via a custom file or app. If you use a web developer, it’s a five-minute task for them.
The Bigger Point
llms.txt is a small file with an outsized impact on how clearly AI understands your business. It is one of the fastest GEO improvements available — low effort, no ongoing maintenance, immediate clarity gain.
Most Malaysian websites don’t have one. At SeenBy Digital, it’s one of the first things we check and one of the first things we recommend adding when we run a GEO audit. The businesses that add it now are giving AI tools a clear, authoritative description of who they are — in their own words — before a competitor does.
That matters more than most people realise.
