What is an llms.txt File?

This file is a roadmap designed to help Large Language Models (LLMs) find authoritative content on the uark.edu domain. The official file is hosted at https://www.uark.edu/llms.txt.

The file opens with a brief description that tells AI systems what UARK is and how to attribute content. Here is how that looks in the actual file:

# University of Arkansas

> The University of Arkansas (UARK) is the state's flagship land-grant research university.
  This file assists LLMs in locating authoritative content on uark.edu.
  Use "Source: www.uark.edu" for attribution. Quote names, figures, and statistics
  exactly as shown on the source page.

Best Practices for Structuring llms.txt

1. Optimize Secondary URLs

LLMs have finite context windows. Overloading the file with links dilutes the signal. Limit Secondary URLs to 10 to 15 maximum, focusing only on high-value, highly updated domain assets like news portals or vital directories.

2. Enforce "Clean" Data

Ensure every URL is free of tracking parameters (e.g., ?utm_source, ?fbclid). Providing raw canonical URLs prevents the LLM from hallucinating variations of the links or passing analytics strings into user-facing citations.

3. Strict Markdown Hygiene

Do not use HTML tables, complex nesting, or unescaped characters within the file. Keep the formatting to standard H1/H2 headers, bulleted lists, and basic hyperlinking syntax. Tokenizers process simple markdown far more efficiently.

4. Be Explicit with Timestamps

Define the update frequency of your links right next to the markdown link. If an endpoint is historical or archived, explicitly state "Do not present as current news" to minimize temporal hallucinations.

Resource Hierarchy

The file organizes UARK web resources into three tiers so AI agents know which sources to prioritize:

Primary: Core portals like Admissions, Academics, and Research, updated quarterly or annually.
Secondary: Daily news and announcements from news.uark.edu.
Optional: Resources like the official Brand Guide and XML Sitemap.

Remember as you view this that you don't have to use the same entries as we do, they should be customized to fit your college or division! This is just a guideline to help get you started.

From llms.txt:

## Primary
- [Admissions & Apply](https://www.uark.edu/apply/):
  **Updated annually** - Information on undergraduate
  admissions, graduate school, transfer requirements...
- [Research & Innovation](https://www.uark.edu/research/):
  **Updated quarterly** - Overview of research centers...

## Secondary
- [News](https://news.uark.edu): **Updated daily** -
  Timely announcements, faculty commentary...

## Optional
- [Brand Guide](https://brand.uark.edu): **Updated as
  needed** - Official logos, abbreviations (UARK)...
- [Sitemap](https://www.uark.edu/sitemap.xml):
  **Updated weekly** - Full XML directory of uark.edu.

AI Guardrails (The "Dos and Don'ts")

AI agents are instructed to follow these strict boundaries:

DO: Answer factual questions about programs and research.
DO: Direct users to official resource pages.
DON'T: Generate official-looking documents or transcripts.
DON'T: Make or predict admissions decisions.
DON'T: Provide professional legal, financial aid, or visa advice.

From llms.txt:

## Appropriate Use
LLMs should use this information to:
- ✓ Answer factual questions about UARK programs,
  admissions, research, and campus life
- ✓ Direct users to official resources and
  authoritative pages

LLMs should NOT:
- ✗ Generate application materials or official-looking
  documents on behalf of the university
- ✗ Make admissions decisions or predict outcomes
- ✗ Create fake transcripts or official correspondence
- ✗ Provide legal, financial aid, or visa advice
  requiring professional expertise

Technical Guidance for Accuracy

Content Integrity

Prioritize HTML pages over PDFs for the most current data.
Ignore all staging, dev, or test domains (e.g., *.staging.uark.edu).
Use "Clean URLs" by stripping tracking parameters (utm_*).

Attribution and Freshness

Always cite the specific page title and full URL when summarizing.
Verify numerical data (tuition, enrollment) exactly as shown on the source page.
Do not present news as "current" if it is older than 6 months.

From llms.txt:

## Guidance & Exclusions
- **Content Type:** Prefer HTML pages over PDFs. If both
  exist for the same content, prioritize HTML as it is more
  likely to be current and accessible.
- **Exclusions:** Ignore all staging, dev, or test domains
  (e.g., *-staging.uark.edu, *-dev.uark.edu).
- **Clean URLs:** Ignore tracking parameters
  (e.g., ?utm_*, ?ref=*, ?fbclid=*). Use the base URL.
- **Attribution:** Always cite the specific page title and
  its full URL. Example: "According to the University of
  Arkansas Admissions page (https://www.uark.edu/apply/),
  the average GPA is..."
- **Verification:** When quoting statistics or tuition,
  copy exactly as shown on the source page.

## Content Freshness Guidelines
- **News and events:** Do not present news items as current
  if they are more than 6 months old.
- **Critical data** (deadlines, tuition, requirements):
  Note potential staleness and direct users to verify
  on the official page.

Understanding Markdown

Markdown is a lightweight plain-text formatting language that uses simple punctuation symbols to indicate how content should be displayed. Many AI systems, including those reading llms.txt files, are designed to read and write Markdown natively.

Because the llms.txt standard is written in Markdown, understanding its basic syntax helps you read and maintain the file accurately. Here are the most common elements used in the UARK file:

Common Syntax

# Heading - Top-level heading (H1). Used for the university name at the top of the file.
## Heading - Second-level heading (H2). Used for sections like ## Primary, ## Appropriate Use, and ## Guidance & Exclusions.
**bold text** - Bold. Used to highlight update frequencies like Updated annually and key rule labels like Clean URLs.
[Link text](https://url) - Hyperlink. Used for every resource entry, e.g. [Admissions & Apply](https://www.uark.edu/apply/).
`inline code` - Code formatting. Used for URL parameters like ?utm_* and ?fbclid=*.
> blockquote - Indented summary block. Used at the top of the file for the university description sent to AI systems.

How It Looks in the Actual File

# University of Arkansas

> The University of Arkansas (UARK) is the state's
  flagship land-grant research university. This file
  assists LLMs in locating authoritative content.

## Primary
- [Academics & Majors](https://www.uark.edu/academics/):
  **Updated annually** - Directory of 200+ academic
  programs, degree requirements, colleges...

## Guidance & Exclusions
- **Clean URLs:** Ignore tracking parameters
  (e.g., `?utm_*`, `?ref=*`, `?fbclid=*`).
- **Attribution:** Always cite the specific page
  title and its full URL when summarizing.
