How scoring works

Based on the llms.txt proposal. Every file starts at 100. Each "must fix" costs 40 points and each "should fix" costs 10. Tips are free. A missing file or a web page scores 0.

CheckLevelPointsWhat it means
File is empty
empty
 Must fix score 0 The address returned nothing. Publish your llms.txt content there.
Web page instead of a file
html
 Must fix score 0 The address returned a web page (HTML). Your site doesn't have an llms.txt yet, or it's in the wrong place.
Missing title
no-h1
 Must fix −40 The file must start with your site or project name as a heading: # Your name.
Title isn't first
h1-not-first
 Must fix −40 Nothing may come before the # title line.
Note above the title
preamble-before-title
 Should fix −10 A plain-text note (often added by SEO plugins like Yoast) sits above the # title. AI tools usually skip it, but the title should come first.
More than one title
multiple-h1
 Should fix −10 Use one # title. Use ## for section headings.
Served with the wrong type
content-type
 Should fix −10 Servers should send llms.txt as text/plain or text/markdown.
File is very large
large
 Should fix −10 Keep llms.txt short (under 1 MB). Put full content in llms-full.txt.
Empty section
section-no-links
 Should fix −10 Each ## section should list pages as: - [Page name](https://url): short note.
Section with text only
text-section
 Tip 0 A ## section that holds text but no links. That's fine for context; AI tools just won't find pages there.
No link sections
no-sections
 Should fix −10 Add at least one ## section listing your most important pages.
Very few pages listed
few-links
 Should fix −10 One or two links don't tell AI tools much. List your 3 to 10 most important pages.
Link isn't a web address
bad-url
 Should fix −10 Links should be full web addresses (https://…) or paths on your site (/page).
Link is missing https://
missing-scheme
 Should fix −10 A link like example.com/page is read as a page on your own site. Write https://example.com/page.
Address repeats the domain
repeated-domain
 Should fix −10 A link like https://site.com/site.com/page is broken. Remove the repeated domain.
Broken link format
malformed-link
 Should fix −10 A list item that looks like a link but won't parse, e.g. brackets in the name or spaces in the address.
No summary line
no-summary
 Tip 0 Optional but recommended: a one-line description after the title, starting with >.
Relative link
relative-url
 Tip 0 Links like /pricing work, but full addresses (https://…) are safer for AI tools.
Insecure link
http-url
 Tip 0 Links that start with http:// work, but https:// is preferred where the page supports it.
List items without links
plain-list-items
 Tip 0 List items inside sections are most useful as links.
Has an Optional section
optional-section
 Tip 0 AI tools may skip the ## Optional section when they're short on space. That's by design.

A minimal valid example

# Example Co

> Example Co makes scheduling software for clinics.

## Main pages
- [Getting started](https://example.com/start): Set up in 10 minutes
- [Pricing](https://example.com/pricing): Plans and prices

## Optional
- [Blog](https://example.com/blog)
