SEO in LLMS: Meet llms.txt, a Proposed Standard for AI Website Content Crawling

To meet the web content crawlability and indexability needs of large language models, a new standards proposal for AI/LLMs by Australian technologist Jeremy Howard is here.

His proposed llms.txt acts somewhat similarly to robots.txt and XML sitemaps protocols, in order to allow for a crawling and readability of entire websites, putting less of a resource strain on LLMs for crawling and discovering your website content.

But it also offers an additional benefit full content flattening – and this may be a good thing for brands and content creators. Creating content that is compelling and useful can lead to brand mentions in LLM outputs and on other websites, which can improve organic traffic and visibility. Creating engaging and valuable content also enhances your website’s presence in search engine results, directly impacting visibility and ranking.

While many content creators are interested in the proposal’s potential merits, it also has detractors.

But given the rapidly changing landscape for content produced in a world of artificial intelligence, llms.txt is certainly worth discussing.

Introduction to Search Engine Optimization

Search Engine Optimization (SEO) is the cornerstone of digital marketing, designed to enhance a website’s visibility and performance in search engines. By optimizing web content, website speed, and overall site structure, businesses can improve their search engine rankings and attract more organic traffic. SEO is not just about inserting keywords; it’s about understanding how search engines evaluate and rank web pages, and then tailoring your site to meet those criteria.

Effective SEO strategies involve a deep dive into how search engines operate, what users are searching for, and how to deliver the most relevant and valuable content. This includes optimizing on-page elements, improving website speed for a better user experience, and ensuring that your site is easy to navigate. The ultimate goal is to make your website the best possible answer to users’ search queries, thereby increasing your site’s authority and driving more qualified traffic.

In today’s competitive web landscape, SEO is an ongoing process that requires regular updates and refinements. By staying current with search engine algorithms and best practices, businesses can maintain strong search engine rankings and ensure their website remains a vital part of their digital marketing strategy.

Introduction to Large Language Models

Large Language Models (LLMs) are transforming the way search engines process and understand web content, making them a central force in today’s digital marketing and search engine optimization (SEO) strategies. These advanced AI systems, such as OpenAI’s ChatGPT and Google’s AI Mode, are designed to interpret natural language, generate human-like responses, and deliver more relevant search results based on the true intent behind search queries.

At their core, LLMs are trained on massive datasets of text, allowing them to recognize patterns, relationships, and context within language. This deep understanding enables LLMs to not only answer questions and generate content, but also to help search engines better interpret the purpose and meaning of web pages. As a result, LLMs are increasingly used to power AI-driven search, providing users with more accurate, contextually relevant answers and improving overall search engine rankings for websites that meet their criteria.

One of the most significant shifts brought about by LLMs is the move from traditional keyword-based SEO to a more nuanced approach centered on natural language processing (NLP). Instead of simply matching keywords, LLMs analyze the intent and context behind search queries, which means that content quality, relevance, and clarity are more important than ever. For businesses and content creators, this means focusing on writing content that is easy to read, up to date, and provides clear value to users.

Optimizing for LLMs involves several best practices that go beyond traditional SEO fundamentals. High-quality, engaging content remains essential, but it’s also important to use descriptive alt text for images, ensure website speed and accessibility, and leverage schema markup to provide structured data and more context for search engines. Keeping content updated by regularly revising web pages with fresh, optimized information and updating publish dates is crucial, as this not only improves search ranking but also increases relevance in LLM citations. LLMs tend to favor pages that are current and relevant, so maintaining content updated can significantly enhance search visibility and organic traffic.

Keyword research is still a vital part of SEO, but with LLMs, it’s important to consider the broader context and related phrases that users might search for. AI tools can assist in identifying these opportunities, helping you optimize your content for a wider range of search queries and improve your website’s presence in search results.

The new proposed standard for AI accessibility to website content

Bluesky CEO Jay Graber propelled the discussion of content creator rights and data control, as it relates to being used for training in AI, on March 10 at SXSW Interactive in Austin, Texas.

Robust and ambitious in its detail, the cited proposal offers much to consider about the future of user content control within LLMs’ vast data and content appetite.

But a potentially simpler potential protocol emerged for web content creators last September, and while not as broad as the other proposal, llms.txt offers some assurance of increased control by the owner, in terms of what, and how much should be accessed.

These two proposals are not mutually exclusive, but the new llms.txt protocol seems to be further along.

Howard’s llms.txt proposal is a website crawl and indexing standard using simple markdown language.

With AI models consuming and generating infinitely vast amounts of web content, content owners are seeking better control over how their data is used, or at least, seeking to provide context on how they would like for it to be used.

You can simply place URLs of a section of a website, a file, or a directory in the llms.txt file to specify what should or should not be accessed. However, providing the same content through multiple URLs or across multiple pages can create duplicate content issues, making it harder for LLMs and search engines to determine which version to prioritize. The llms.txt file can help consolidate and clarify which version should be prioritized for LLMs, improving SEO in llms by reducing confusion from multiple pages and multiple URLs.

Short of exceeding the astoundingly high bar of crawl capabilities of a Google or Bing, LLMs are in need of a solution that allows them to focus less on becoming a massive crawling engine, and more on the “intelligence” part of their functions, as artificial as they may be.

Theoretically, llms.txt provides a better use of technical resources for LLMs.

This article will explore:

• What llms.txt is.
• How it works.
• Some ways to think about it.
• Whether LLMs and content owners are “buying-in”.
• Why you should pay attention.

What llms.txt is and what it does for large language models

For the purpose of this article, it is best to quote Howard’s proposal to help reveal what he intends for this new standard to accomplish::

*“*Large language models increasingly rely on website information, but face a critical limitation: context windows are too small to handle most websites in their entirety. Converting complex HTML pages with navigation, ads, and JavaScript into LLM-friendly plain text is both difficult and imprecise.

“While websites serve both human readers and LLMs, the latter benefit from more concise, expert-level information gathered in a single, accessible location. This is particularly important for use cases like development environments, where LLMs need quick access to programming documentation and APIs.

*“*We propose adding a /llms.txt markdown file to websites to provide LLM-friendly content… llms.txt markdown is human and LLM readable, but is also in a precise format allowing fixed processing methods (i.e. classical programming techniques such as parsers and regex).

The potential uses for this proposed protocol are quite intriguing for GEO benefits, and I’ve been testing it since December.

In its essence, llms.txt let you provide context on how your content can be accessed and used by AI-driven models.

Similar to robots.txt, which controls how search engine crawlers (or should) interact with a website, llms.txt would establish guidelines for AI models that scrape and process content for training and response generation. Search engines and LLMs evaluate the content and structure of each given page, so clarifying the page purpose in llms.txt helps ensure Google sees the intended information for optimal indexing and ranking. Unlike deceptive SEO tactics such as hiding text off screen to manipulate search rankings, llms.txt promotes transparency by explicitly stating which content should be accessible to AI models.

There is no real “blocking,” and robots.txt directives (ex. “Disallow:”) are not intended for the llms.txt file. When set up properly, it is rather more of a “choosing” about which content should be shown contextually or wholly to an AI platform.

You can simply place URLs of a section of a website, add URLs with summaries of a website, or even provide the full raw text of a website in single or multiple files.

The llms.txt file on one of my websites is 115,378 words long, 966 kb file size, and contains the complete flattened website text in a single .txt file, hosted on the domain root. But your file can be smaller, even potentially larger than this file size, or even broken out into multiple files. It can be stored in multiple directories of your taxonomy and architecture, as needed.

You can also create .md markdown versions of each of your web pages that you believe deserves the attention of an LLM. It is very handy when performing deep site analysis, and it is not just for the LLMs. Just as websites serve many various uses, llms.txt follows in this regard, with many possible variations for providing context to LLMs.

Generating an llms.txt or llms-full.txt file

It is almost “elegant” in its simplicity, in that it strips complete sites down to their bare linguistic and textual essence, making it easier fodder to parse by your favorite platform, for myriad uses in content development, site structure analysis, entity research, and just about anything else you can dream up. Generating an llms.txt file also allows you to collect valuable data points about your website, such as the distribution of internal links and the accessibility of content for screen readers, which can inform further SEO improvements.

It also provides a standardized method for website owners to explicitly allow or disallow LLMs from ingesting and utilizing their content. The proposal is gaining traction among tech industry leaders and professionals as AI continues to reshape the digital landscape. The absolute utility for increasing relevance is there, with benefits for the LLM, the website owner, and the user who theoretically finds a better answer via this little textual handshake.

Llms.txt functions similarly to robots.txt, only in the sense of creating a simple text file in the root directory of their website. Much like the robots.txt file standard, it can be obeyed, or not, depending on whether or not the AI/LLM agent wants to. But to clear up a common misperception, it IS NOT intended for robots.txt directives to be included in the llms.txt file.

Optimizing Content for AI Mode

Optimizing content for AI Mode means going beyond traditional SEO tactics and focusing on how AI tools and systems interpret and interact with your site. This involves creating content that is not only easy to read for users but also structured in a way that AI can understand and process effectively. Leveraging structured data and natural language processing techniques helps provide more context to AI systems, making your content more discoverable and relevant in AI-driven search environments.

To succeed in AI Mode, prioritize semantic signals and use descriptive alt text to give both users and AI tools a clearer understanding of your content. Focus on user intent by crafting content that answers real questions and provides value, rather than just targeting keywords. Incorporating structured data, such as schema markup, can further enhance search visibility by helping AI systems interpret the purpose and context of each page.

Ultimately, optimizing for AI Mode is about creating content that bridges the gap between traditional SEO and the needs of modern AI-driven search. By doing so, you can improve your site’s ranking, increase visibility, and ensure your content stands out in both search engine results and AI-powered platforms.

The Importance of Google Sees

Understanding how Google sees your website is fundamental to effective search engine optimization. Google’s algorithms don’t just scan your web pages for keywords—they interpret the structure, content quality, and relevance of your site in relation to user search queries. This interpretation, often referred to as “Google sees,” directly impacts your search engine rankings and overall search visibility.

To optimize for how Google sees your website, it’s essential to focus on structured data, clear site architecture, and high-quality content that addresses the needs of your audience. Implementing structured data helps Google better understand the context and purpose of your pages, making it easier for your content to appear in relevant search results. Consistent keyword research ensures that your content aligns with what users are actually searching for, while maintaining content quality keeps your site authoritative and trustworthy in Google’s eyes.

By prioritizing these elements, you can improve your website’s visibility in search results, drive more organic traffic, and strengthen your online presence. Remember, effective SEO is about optimizing not just for users, but also for how Google interprets and ranks your site—ensuring your content is seen, understood, and valued by both search engines and your target audience.

Increasing Prominence with LLM Outputs

Large language models are rapidly changing the way search engines evaluate and rank web content. To increase your website’s prominence with LLM outputs, it’s crucial to create content that is not only relevant and engaging but also optimized for natural language processing. This means structuring your web pages with clear header tags, using descriptive alt text for images, and building a strong network of internal links to guide both users and AI systems through your content.

Leveraging LLM outputs can also inspire new content ideas and help you identify gaps in your existing material. By analyzing how language models interpret and summarize your site, you can optimize your content to better align with user intent and search queries. This approach not only improves your search visibility but also ensures your website remains relevant as AI-driven search becomes more prominent.

Focusing on high-quality, well-structured content and regularly updating your site with new, optimized material will help you stay ahead in the evolving landscape of search. By embracing LLM outputs as part of your SEO strategy, you can enhance your website’s visibility, improve search engine rankings, and ensure your content stands out in both traditional and AI-powered search environments.

The Impact of Other Websites

The influence of other websites on your search engine rankings is significant and multifaceted. High-quality backlinks from reputable sites act as endorsements, signaling to search engines that your content is trustworthy and valuable. These links can dramatically boost your search visibility and help your website climb higher in search results.

Brand mentions on other websites, even without direct links, can also enhance your site’s credibility and relevance. When your content is referenced by authoritative sources, it increases your website’s authority in the eyes of search engines, leading to improved rankings and greater visibility.

Creating engaging, high-quality content is key to attracting these valuable links and mentions. By actively monitoring your niche, building relationships with other creators, and participating in relevant online communities, you can encourage more brand mentions and backlinks. This positive feedback loop not only strengthens your search engine rankings but also expands your reach and influence across the web.

Adoption

Many different LLMs have voiced their support for the llms.txt standard,and many are using it, or exploring its usefulness. llms.txt Hub has compiled a list of AI developers using the standard for documentation, and claims to be one of the largest such resources for identifying them. But remember, llms.txt is not just for developers, it is for all web content owners and producers.

Website and content creators can also benefit greatly from a flattened file of their site. Once the llms.txt file is in place, full site content can be analyzed, however it may fit the needs of your research method. However, relying solely on LLM outputs for content can be risky, as these may be outdated or less valuable for SEO. Incorporating user generated content and forum posts provides fresh, authentic information that improves SEO and increases LLM relevance, while also demonstrating community engagement and keeping your site updated for search engines.

llms.txt Generator Tools

With the basic protocol outlined, there are a variety of tools available to help generate your file. I have found that most will generate smaller sites for free, and larger sites can be a custom job. Of course, many website owners will choose to develop their own tool or scraper. Word of caution – research the security of any generator tool before using, and review your files before uploading. DO NOT use any tool without first vetting security. Here are a few of those free tools to check (but still subject to your own validation):

• Markdowner – A free, open-source tool that converts website content into well-structured Markdown files.
• Appify –  Jacob Kopecky’s llms.txt generator.
• Website LLMs – This WordPress plugin creates your llms.txt file for you. Just set the crawl to “Post”, “pages,” or both, and you’re in business. I was one of the first ten people to download this plugin; now it is at over 3,000 downloads in just three months.
• FireCrawl – One of the first tools to emerge for the creation of llms.txt files.

While llms.txt improves content extraction clarity, it could also introduce security risks that require careful management. This article does not address those risks, but it is highly recommended that any tool is fully vetted before deploying this file.

Why llms.txt could matter for SEO and GEO

Controlling how AI models interact with your content is critical, and just having a fully flattened version of a website can make AI extraction, training, and analysis much simpler. Here are some reasons why:

• Protecting proprietary content: Prevents AI from using original content without permission, but only for the LLMs that choose to obey the directives.
• Brand Reputation Management: It theoretically gives businesses some control over how their information appears in AI-generated responses.
• Linguistic and content analysis: With a fully flattened version of your site that is easily consumable by AI, you can perform all kinds of analysis that typically require a standalone tool. Keyword frequency, taxonomy analysis, entity analysis, linking, competitive analysis, etc.
• Enhanced AI interaction: llms.txt helps LLMs interact more effectively with your website, enabling them to retrieve accurate and relevant information. No standard needed for this option, just a nice clean and flattened file of your complete content.
• Improved content visibility: By guiding AI systems to focus on specific content, llms.txt can theoretically “optimize” your website for AI indexing, potentially improving your site’s visibility in AI-powered search results. Like SEO, there are no guarantees. But on the face of it, any preference that an LLM has towards a llms.txt is a step forward. Regularly updating your content and reflecting these changes in schema markup can improve your website’s ranking and increase its prominence in both traditional and AI-driven search results.
• Better AI performance: The file ensures that LLMs can access the most valuable content on your site, leading to more accurate AI responses when users engage with tools like chatbots or AI-powered search engines. I use the “full” rendering of llms.txt, and personally do not find the summaries or URL lists any more helpful than robots.txt, or an XML sitemap. Optimizing for faster load times and clear navigation can improve user engagement metrics such as click through rates, which are increasingly important for search engine ranking.
• Competitive advantage: As AI technologies continue to evolve, having an llms.txt file can give your website a competitive edge by making it more AI-ready.

Maintaining and optimizing your llms.txt file is an ongoing process. Consistently updating your content and strategies helps sustain your website’s presence and visibility, supporting higher ranking and increasing prominence in evolving search environments.

Challenges and limitations

While llms.txt offers a promising solution, several key challenges remain:

• Adoption by AI companies: Not all AI companies may adhere to the standard, and will just ignore the file, and ingest all of your content any way.
• Adoption by websites: Simply put, brands and website operators are going to have to step up and participate if llms.txt will be successful. Maybe not all, but a critical mass will be necessary. In the absence of any other type of scientific “optimization” of AI, what have we got to lose? (I still really think it is a mistake to apply an old term like “optimization” to generative AI. It just seems linguistically lazy).
• Overlap with robots.txt and XML sitemaps: Potential conflicts and inconsistencies between robots.txt, XML sitemaps, and llms.txt could create confusion. To repeat, the llms.txt file is not intended to be a substitute for robots.txt. As previously mentioned, I find the most value in the “full” rendering of the text file.
• Keyword, content, and link spamability: Much like keyword stuffing was used in the SEO days of yore, there is nothing to stop anyone from filling up their llms.txt with gratuitous loads of text, keywords, links, and content. Publishing the same content across multiple URLs or pages can lead to a bad user experience and negatively impact SEO, especially for ecommerce brands that manage large catalogs.
• Exposure of your content to competitors for their own analysis. While scraping is a basic cornerstone of the entire search industry, competitive keyword and content research is nothing new. But having this simple file lowers the bar a bit for your competitors to easily analyze what you have – and don’t have – and use to their competitive advantage.

Other contrarian views about llms.txt exist in the SEO/GEO community. I had a message chat with Pubcon and WebmasterWorld CEO Brett Tabke about llms.txt. He said he doesn’t believe it offers much utility:

• “We just don’t need people thinking they [LLMs] are different from any other spider. The dividing line between a ‘search [engine]’ and an ‘llm’ is barely arguable any more. Google, Perplexity, and ChatGPT have blurred that into a very fuzzy line with AI responses on SERPs. The only distinguishing factor is that Google is a search engine with an LLM bolted on, and ChatGPT is an LLM with a search engine bolted on. Going forward, it is obvious that Google will merge their LLM directly with the code base of the search engine and blow away any remaining lines between the two. LLMs.txt simply obfuscates that fact.”

XML sitemaps and robots.txt already serve this purpose, Tabke added.

On this point, I agree wholly. But for me, the potential value lies mostly in the “full” text rendering version of this file.

Marketer David Ogletree also has similar reservations:

• “If there is a bottom line, it is that I really don’t want people continuing this idea that there is a difference between a LLM and Google. They are one in the same to me and should be treated the same.”

Common Mistakes in LLM SEO

As websites adapt to the rise of large language models, several common mistakes can hinder their LLM SEO efforts. One frequent error is neglecting to optimize content for natural language processing—failing to use clear, descriptive alt text, header tags, and well-structured content can make it harder for AI systems to interpret your site accurately. Another pitfall is prioritizing keyword stuffing over creating high-quality, engaging content, which can lead to a poor user experience and reduced search visibility.

Many websites also overlook the importance of keeping their content up to date. Outdated information can cause a drop in search engine rankings and make your site less relevant in LLM outputs. Additionally, slow website speed can negatively impact both user experience and search performance, as search engines increasingly prioritize fast-loading sites.

Finally, some miss the opportunity to leverage LLM outputs for generating new content ideas and optimizing existing material. By regularly analyzing how language models interpret your site, you can identify areas for improvement and ensure your content remains relevant and visible.

Avoiding these common mistakes and focusing on high-quality, user-focused content, technical optimization, and ongoing updates will help you maximize your LLM SEO efforts and maintain strong search visibility in an AI-driven world.

Measuring Success in LLM SEO

Measuring the effectiveness of your LLM SEO strategy requires a data-driven approach. Start by tracking your search engine rankings and monitoring organic traffic to see how your site is performing in search results. Tools like Google Analytics provide valuable data points, such as click-through rates, bounce rates, and time on site, which can help you assess how users are engaging with your content.

It’s also important to keep an eye on brand mentions and user-generated content, as these can influence your website’s authority and relevance in the eyes of both search engines and AI systems. Monitoring website speed is crucial, as faster sites tend to rank higher and provide a better user experience, which can lead to increased organic traffic and improved conversion rates.

By regularly analyzing these metrics, you can identify what’s working and where there’s room for improvement. This ongoing process allows you to refine your LLM SEO strategy, align it with your broader digital marketing goals, and ensure your website remains competitive in an ever-evolving search landscape.

The future of llms.txt and AI content governance

As AI adoption continues to grow, so does the need for structured content governance.

llms.txt represents an early effort to create transparency and control over AI content usage. Whether it becomes a widely accepted standard depends on industry support, website owner support, regulatory developments, and AI companies’ willingness to comply.

You should stay informed about llms.txt and be prepared to adapt their content strategies as AI-driven search and content discovery evolve. Optimizing for both traditional search engines and AI-driven platforms, as well as earning mentions on other websites and social media platforms, can further enhance your site’s visibility and authority.

The introduction of llms.txt marks a significant step toward balancing AI innovation with content ownership rights, and the “crawlability and indexability” of websites for consumption and analysis by LLMs.

You should proactively explore its implementation to safeguard your digital assets, and also provide LLMs a runway to better understand the structure and content of your site(s).

As AI continues to reshape online search and content distribution, having a defined strategy for AI interaction with your website will be essential.

llms.txt could create a little bit of science for GEO

In GEO, much like SEO, there are literally almost no scientific standards for web creators to base on. In other words, verifiable best platform practices based on specific tactics.

Any buzzy acronym containing a big “O” (optimization) is black box engineering. Or, as another tech development executive I worked with calls it, “wizardry,” “alchemy,” or “digital shamanism.”

For example:

• When Google says “create great content for users, and then you will succeed in search” – that’s an art project on your part.
• When Google says, “we follow XML sitemaps as a part of our crawler journey, and there is a place for it in Google Search Console,” well, that’s a little bit of science.
• And the same for schema.org, robots.txt, and even IndexNow. These are “agreed upon” standards that search engines tell us definitively, “we do take these protocols into consideration, though at our own discretion.”

In a world of so much uncertainty with what “can be done” for improving AI and LLM performance, llms.txt sounds like a great start.

If you have a wide content audience, it may bode well for you to get your llms.txt file going now. You never know what major or specialized LLM may want to use your content for some new purpose. And in a world shifting from the multiple decisions required of a searcher of a cluttered results page, the LLM provides the answer

If you are playing to win, then you want your content to be that answer, as it is potentially worth a multitude of search engine searches.

I started implementing llms.txt on my own websites a few months ago, and am implementing it on all my clients’ websites. There is no harm in doing so. Anything that can potentially help “optimize” my content should be done, especially as a potentially accepted standard.

Are all the LLMs using it? It is definitely not even near critical mass, but some have reported an interest.

Can an llms.txt file also help you better access and crawl your own website for various AI uses? Absolutely.

One of the main uses I have found is in analyzing client sites in various ways. Having the entirety of your website content in a file can allow for different types of analysis that were not as easy to render previously. Publishing new content regularly and referencing insights from other creators can further improve your site’s authority and relevance, especially as llm seo becomes more important for optimizing content for AI-driven search engines.

Staying Ahead of the Competition

In the fast-paced world of LLM SEO, staying ahead of the competition means embracing an ongoing process of optimization and innovation. Focus on creating high-quality, relevant content that addresses the needs of both users and AI systems. Regularly update your site to keep it fresh and ensure that your content remains authoritative and valuable.

Website speed, mobile-friendliness, and a seamless user experience are essential for maintaining strong search engine rankings and keeping users engaged. Leverage AI tools and adhere to SEO fundamentals to stay up to date with the latest trends and best practices. This proactive approach will help you adapt to changes in search algorithms and AI technologies, ensuring your site remains visible and competitive.

By continuously monitoring your performance, analyzing data, and optimizing your strategy, you can maintain your website’s presence in search results and drive ongoing growth. Staying ahead in LLM SEO is not a one-time effort—it’s a commitment to excellence and relevance in the ever-changing digital marketing landscape.

Will it become a standard?

It definitely remains to be seen. llms.txt has a long road ahead, but I wouldn’t bet against it.

Where companies are looking for new ideas to improve their presence as “the answer” in LLMs, it offers one new signal for AI optimization and possibly one step ahead for connecting with LLMs in a way that was previously only comparable to search engines.

And don’t be surprised if you start hearing a lot more SEO/GEO practitioners talking about llms.txt in the near term, as a basic staple for site optimization, along with robots.txt, XML sitemaps, schema, IndexNow, and others.
