The conversation about llms.txt files is dominated by the wrong question.
I keep seeing two camps: one saying every business needs to build one now, another pointing to the data and saying it’s a waste of time.
The value of an LLMs.txt file has almost nothing to do with whether LLMs are reading it today. It’s a positioning exercise.
It forces your business to define in plain language who you are, what you’re exceptional at, and where you’re not the right choice. That exercise has value on its own.
The LLM visibility upside comes later.
What Is an LLMs.txt File?
An LLMs.txt file is a plain-text, markdown-formatted document placed at the root directory of your website (yourdomain.com/llms.txt) that tells large language models about your business.
The concept was proposed in 2024 by Jeremy Howard as a way to help AI tools quickly understand a site’s most important content, without requiring them to crawl hundreds of pages.
Think of it as a cross between a robots.txt file (which tells crawlers what to access) and a sitemap.xml (which maps your site’s structure), except LLMs.txt is written in plain language for generative AI tools like ChatGPT, Claude, Perplexity, and Gemini to read.
The standard also includes an optional companion file, llms-full.txt, which contains the full text of your key pages rather than just a summary index. For most ecommerce businesses, the standard llms.txt file is the right starting point.

The LLMs.txt File Debate Is Framed Wrong
The debate right now is about whether or not creating an LLMs.txt file helps your business show up in large language models.
Ahrefs analyzed 137,000 sites in June 2026 and found that 97% of llms.txt files received zero traffic in May 2026. Of the small fraction that did get traffic, only 19.5% of traffic came from AI tools.
The data is right. The conclusion most people draw from it is wrong.
Most marketers look at how infrequently LLMs crawl LLMs.txt files and assume there’s no benefit to creating them.
No One Reading It Is Exactly the Opportunity
The businesses building llms.txt files today aren’t getting a ranking bump. They’re getting a head start.
At some point, one major LLM is going to formally adopt the llms.txt standard. When that happens, the others will follow fast. That’s how this space moves.
ChatGPT, Claude, Gemini, and the AI agents built on top of them are all competing for the same users. A feature one adopts to better understand websites becomes a feature that others have to match.
When that happens, every business paying attention to AI visibility will scramble to get a file up and running.
Your competitors will be starting from scratch. You’ll already be done.
The question isn’t whether LLMs are reading these files today. The question is whether you want to be ready when they do.
In fairness, this is hypothetical. There’s no evidence to suggest that LLMs will start crawling these files.
So let’s assume LLMs never adopt this concept. Do LLMs.txt files have value?
The Real Value of LLMs.txt Files
An llms.txt file is a publicly facing positioning statement.
It’s one document that answers:
- What does your business do?
- What are you exceptional at?
- What don’t you do as well as competitors?
- Who do you serve?
- What are the scenarios where a customer should choose you over someone else?
Most businesses have never put this on paper. They’ve tried to appear capable of more to capture more market share. The thought has always been that broader positioning means more opportunity.
Building an llms.txt file forces the internal conversation your business has probably been avoiding:
What are we actually best at?
What are we not?
Where do we win, and where should we refer someone elsewhere?
That conversation has real value independent of any generative AI tool ever reading the output.
Why AI Rewards Specificity in a Way Search Never Did
Traditional search rewarded breadth.
More keywords meant more rankings. More rankings meant more traffic. For years, the winning search positioning strategy was to call yourself a Denver pizza shop with “great pizza” and capture every variation of that query.
LLMs are built differently. They’re exceptional at responding to hyper-specific queries that traditional search engines aren’t well suited for.
If someone asks an LLM to find a New York-style pizza place in Denver with craft beer on draft, the LLM surfaces the businesses that clearly positioned themselves that way. Not the ones that broadly called themselves a great pizza place.
The brands that take a firm stance on who they are get recommended. The ones that hedge get passed over.

Small Brands Have a Window That Large Brands Don’t
Think about what it takes for a billion-dollar company to formalize a positioning statement.
That’s a 12-24 month project. It involves leadership alignment, brand consultants, legal review, and stakeholder sign-off, given competing interests in how the company describes itself.
You can do this in an afternoon.
If you’re running an ecommerce business in the $2M to $20M range, you know who your best customers are. You know what you’re great at and what you’re not. You know which competitors you beat and which you don’t.
The hard part is putting them in writing publicly.
Build your LLMs.txt file now.
Not because LLMs are going to analyze your file this week and send you a wave of traffic. Do it because you and your team need to agree on how you position yourself publicly, and your file will already be live when the rest of your industry is scrambling.
Recommended action steps:
What to Actually Put in the LLMs.txt File
There’s no enforced standard for llms.txt content. You can write this in plain language.
Here’s what to include:
- Business summary. One to two sentences on what you do and who you do it for. Be specific. “We help ecommerce brands in the home goods space grow organic revenue through content and SEO” is better than “we’re a digital marketing agency.”
- What you’re exceptional at. Most businesses get uncomfortable and write something vague. Don’t. If you’re the best in your market at a specific thing, say that.
- What you don’t do as well as competitors. Yes, put this in. An LLM that understands your limitations routes the right customers to you and the wrong ones elsewhere.
- Products or services. A brief, scannable list. Don’t treat this like a sales page.
- Customer proof. Two or three short quotes from happy customers or a sentence summarizing a case study result.
- Who you’re right for. Describe the scenarios where your business is the clear choice.
Put another way: your llms.txt file is the document you’d hand to someone if they asked you to explain your business in plain language, without marketing gloss.
Frequently Asked Questions About LLMs.txt Files
Does an llms.txt file help with SEO?
Not directly. No major search engine currently uses llms.txt as a ranking signal, and the Ahrefs study published in June 2026 confirmed that AI crawlers are largely ignoring these files today.
The near-term value is internal: building one forces your business to formalize its positioning. The upside in SEO and AI visibility comes if and when large language models formally adopt the standard.
How do I create an llms.txt file?
Write it as a plain text file and upload it to the root directory of your website so it’s accessible at yourdomain.com/llms.txt. No special tools are required.
The file should cover your business summary, what you’re exceptional at, your products or services, customer proof, and the scenarios where you’re the right choice over a competitor.
Keep it readable for people, not just machines.
Are there llms.txt generators I can use?
Yes, several llms.txt generator tools exist that will prompt you for information about your business and output a formatted file. They’re a reasonable starting point, but treat the output as a first draft. The positioning work, deciding what you’re genuinely exceptional at and what you’re not, is something that requires real thought.
What’s the difference between llms.txt and llms-full.txt?
The standard llms.txt file is a summary index: a high-level description of your business and links to key pages. The llms-full.txt file contains the actual full text of those pages, giving large language models more context without requiring them to crawl your site.
How do I add an llms.txt file to WordPress?
The simplest method is to create the file as a plain text document and upload it via FTP or your hosting file manager to the root of your WordPress installation (the same directory as wp-config.php). Some plugins can handle this automatically if you prefer not to work directly in the file manager. Once uploaded, verify it’s live by visiting yourdomain.com/llms.txt in your browser.
What’s the difference between llms.txt and robots.txt?
Robots.txt tells crawlers what they’re allowed or not allowed to access on your site. An llms.txt file does the opposite: it’s a document you publish to proactively share information about your business with AI tools.
Conclusion
LLMs aren’t reading your llms.txt file today. Build it anyway.
The businesses that treat it as a positioning exercise now, defining what they’re exceptional at, what they’re not, and who they’re for, will have that file live when the standard gets adopted. Their competitors will be starting from scratch.
If you’re competing against a large brand, you’re looking at an 18-month head start before they finish the internal process to publish theirs.
