4. The plain-text summary for machines
What this is
A short file at the root of the site that tells an assistant, in plain markdown, what the business is and which pages matter.
Why this matters for vitadefence.com
An assistant that lands on vitadefence.com has to work out what the business is from the HTML. This file tells it directly, in 30 lines built from your own pages.

Step 2 — Publish the 25 markdown copies
Each of your pages gets a plain-markdown twin at its own address. They are written for you already and sit in packs/04-llms-txt/markdown/. The addresses they belong at:
- https://vitadefence.com/articles.md
- https://vitadefence.com/articles/acai-berry-multi.md
- https://vitadefence.com/articles/acerola-multi.md
- https://vitadefence.com/articles/african-mango.md
- https://vitadefence.com/articles/aloe-vera-multi.md
- https://vitadefence.com/articles/amino-acid-multi.md
- https://vitadefence.com/articles/apple-cider-multi.md
- https://vitadefence.com/articles/apple-cider-vinegar.md
(the first 8 of 25 - every address is in packs/04-llms-txt/markdown/)
Step 3 — Point at them, one way or the other
Use either form. Not both.
As HTML, in the <head>:
<link rel="describedby" href="https://vitadefence.com/llms.txt">
<link rel="alternate" type="text/markdown" href="https://vitadefence.com/index.html.md">
Or as an HTTP response header, which also covers the markdown files themselves and can be set in your server or CDN without touching a page:
Link: <https://vitadefence.com/index.html.md>; rel="alternate"; type="text/markdown", <https://vitadefence.com/llms.txt>; rel="describedby"
In the words of the company that published this
llmstxt.org: “The file can be placed at the site root, or at any path within it, covering the pages under that path.” The markdown copies go “at the same URL as the original page, either with .md appended (page.html.md) or with the extension replaced by .md (page.md)”. The pointer “can be provided as HTML <link> elements, or as an HTTP Link: response header… and can be added in web server or CDN configuration without modifying any pages.”
Their page: llmstxt.org
How to check you did it right
- Open https://vitadefence.com/llms.txt in a browser. It should return the file, not a 404, and start with
# Vitadefence UK · Premium supplements · Made in the UK. - Open one of the markdown addresses above; it should return plain text, not HTML.
What it looks like when it is working
- https://vitadefence.com/llms.txt answers, the pointer is in place, and the faults listed above stop being reported.
- The faults to clear: 3 list items under ‘What we sell’ have no
[name](url)link, which their spec requires; 5 list items under ‘Why a buyer might pick us’ have no[name](url)link, which their spec requires; 3 list items under ‘Markets and websites’ have no[name](url)link, which their spec requires.
In two lines
- An assistant that lands on vitadefence.com has to work out what the business is from the HTML. This file tells it directly, in 30 lines built from your own pages.
- First publish the file at your root, then publish the 25 markdown copies, then point at them, one way or the other.
The words in plain English
<head>— the hidden top part of a web page’s code, where settings and tags live - visitors never see it, machines read it first.- robots.txt — a small public text file at yoursite.com/robots.txt that tells crawlers which parts of the site they may read.
- sitemap — the list of your pages, usually at yoursite.com/sitemap.xml, that search engines treat as your site’s own inventory.
- llms.txt — a plain-text summary of your site, placed at the root, written for the AI assistants to read.
- markdown — plain text with light formatting marks; a markdown twin is a plain-text copy of a page at its own address.
- HTTP header — a line your server sends along with a page - invisible to visitors, read by machines.
- CDN — the delivery service that hands out your pages from servers near the visitor; many sites set their headers there.
- answer engine — an AI assistant - ChatGPT, Claude, Perplexity, Google’s AI - that answers a question by quoting pages it can read.
