llms.txt for Squarespace: How to Turn It On and What to Write in It (2026)

What Is an llms.txt File, in Plain Terms?

An llms.txt file is a short Markdown file at your site’s root, at yoursite.com/llms.txt, that gives AI assistants a curated, plain-text map of your most important pages. Unlike a sitemap, which lists everything for search engines, llms.txt lists only the pages that matter most, each with a one-line description, so an AI tool can find the right page without wading through navigation menus, ads, and JavaScript. The format is a proposed standard maintained at llmstxt.org, designed to sit alongside robots.txt and sitemap.xml, not replace them. For the full background, start with our guide, What Is an llms.txt File? Complete Guide for Website Owners (2026).

That matters for Squarespace owners in particular: Squarespace does not let you drop arbitrary files at your domain root the way self-hosted WordPress does, so users spent years working around it with redirects and uploads. The native setting changes that — on version 7.1, you type the content into a Squarespace panel and Squarespace serves it at /llms.txt.

Can You Add llms.txt to Squarespace?

Yes — if your site runs on Squarespace version 7.1, you can add an llms.txt file with Squarespace’s built-in setting, no plugin, code injection, or external host required. Squarespace’s help page, Create an llms.txt file, confirms the file can be created on version 7.1 sites through the SEO/AI Visibility panel. It is disabled by default, so nothing appears at /llms.txt until you add text and save.

Version 7.0 sites do not get this setting. If you are on 7.0, your options are the older workarounds covered later in this post — hosting the file elsewhere and redirecting /llms.txt to it — or moving to a 7.1 template. Check your version before you start.

How to Turn On llms.txt for Squarespace (Step by Step)

Turning on llms.txt for Squarespace takes about five minutes once your text is written. Follow Squarespace’s official steps exactly, because the file stays disabled until you save text into it.

1. Open the SEO/AI Visibility panel. From your Squarespace dashboard, open the SEO/AI Visibility panel for the site you want to update.
2. Go to SEO Settings, then the LLMS.txt tab. Click SEO Settings, then click the LLMS.txt tab.
3. Paste your llms.txt text into the field. The file is disabled by default. Adding text to the field is what enables it — an empty field means no file is served.
4. Click Save. Squarespace now serves your file at yoursite.com/llms.txt.
5. Verify it in a browser. Open yoursite.com/llms.txt in a private or incognito window. You should see your plain Markdown text, not a 404 page and not your homepage.

To turn the file off again later, open the same SEO Settings > LLMS.txt tab, click Delete, then click Save. Removing the file is instant, so do not delete it casually.

What to Write in Your Squarespace llms.txt File

Your Squarespace llms.txt file should be short, factual, and written for a machine reader that has never seen your site. Squarespace itself offers no template and, in its own words, “can’t offer specific advice on creating text for your llms.txt file, as it’s a proposed standard that’s still actively in development” — so the structure below follows the current llmstxt.org specification (v2).

Under that specification, only one part is strictly required: an H1 with your site or project name. A blockquote under the H1 gives a one- or two-sentence summary of the site. Then H2 sections group your links — for example, Services, Products, or Guides — each written as [Page title](https://yoursite.com/page): one-line description. A final ## Optional section holds useful-but-secondary pages a reader can skip when context is tight. Use absolute URLs throughout, because the file is fetched on its own and relative links break outside their page.

Here is a copy-paste template for a typical Squarespace business site. Replace the example names and URLs with your own:

# Rosewood Studio

> Rosewood Studio is a portrait photography studio in Austin, Texas.

Rosewood Studio books sessions online and publishes pricing and a portfolio.

## Services

- [Portrait sessions](https://example.com/portrait-sessions): Family, wedding, and headshot packages and pricing
- [Book a session](https://example.com/book): Online booking, availability, and deposit details

## About

- [About Rosewood Studio](https://example.com/about): Background, studio location, and contact details

## Optional

- [Photo blog](https://example.com/blog): Recent sessions and studio news

That example is deliberately small. A good llms.txt file is not a second sitemap. Pick the five to fifteen pages a stranger would need to understand what you sell, what you charge, and how to reach you, and put the rest in Optional or leave them out.

What to Put In — and What to Leave Out

The strongest Squarespace llms.txt files lead with facts an AI assistant can actually use: what the business does, where it operates, what it charges, and how to book or buy. Vague adjectives answer no real question, while “family portrait sessions from $250, booked online with a $50 deposit” answers three at once. Describe each link in plain language, and stay current: a link to a discontinued service or a deleted page is worse than no link at all.

Just as important is what to leave out. Do not paste your entire sitemap, tag and category archives, paginated blog indexes, or draft pages into the file. Do not add claims you cannot back up, keyword-stuffed descriptions, or pages that require a login. And do not copy another site’s file: the H1, summary, and link descriptions should describe your site, not someone else’s. When your prices, services, or contact details change, update the llms.txt text in the same sitting — an edit and a Save is all it takes.

How to Verify Your File Works

Verification is the step most tutorials skip, and it catches the mistakes. After you save, check three things. First, open yoursite.com/llms.txt in a private browser window and confirm you see your Markdown text, not a Squarespace 404 page. A 404 usually means the file is still disabled (the field was saved empty) or you are on a 7.0 site without the native setting. Second, click two or three links in the file and confirm each lands on a live page. Third, re-read the file as a stranger would: does the H1 name your business, does the summary say what you do, and is it clear which link covers pricing, booking, or contact details?

One more check is worth doing: confirm your robots.txt settings are not blocking the AI crawlers you want to reach. llms.txt and robots.txt do different jobs — robots.txt says what crawlers may access, llms.txt says what the allowed content means — and a file no crawler may fetch helps no one. See our comparison, llms.txt vs robots.txt: What’s the Difference — and Do You Need Both?. And if writing from scratch feels like work, our free tool at llmsgenerate.com generates a starter llms.txt from any site’s sitemap, which you can paste into Squarespace’s LLMS.txt field and edit.

What If Your Site Is on Squarespace 7.0?

If your site is on Squarespace 7.0, the native LLMS.txt tab is not available, so the older workarounds are your only route. Historically, Squarespace owners handled this two ways: uploading the file through Squarespace’s file storage (which serves uploads under /s/) and redirecting /llms.txt to it, or hosting the file externally, such as on a GitHub Gist, and adding a URL Mapping from /llms.txt to that hosted URL. URL Mappings are not available on every plan — third-party guides note the Personal plan cannot use them — so check your plan first.

Both workarounds share a weakness: a redirect hop between the standard location and the actual file, and a mistyped mapping line is silently ignored. They also need manual upkeep. If llms.txt matters long-term, the cleaner path is a 7.1 site. Do not run a workaround and the native setting at once.

Does llms.txt Help Your Squarespace SEO?

The honest answer is that llms.txt is not a confirmed Google ranking factor, and no one should sell it as one. Google has not said the file influences search rankings, and the major AI search systems have not confirmed they use it for citations. What the file does, on the evidence available today, is narrower and still useful: it gives AI assistants and coding agents a clean, curated starting point for understanding your site, instead of leaving them to reconstruct it from HTML. That is a plausible benefit for discovery in AI answers, not a promised ranking boost or guaranteed citation.

If a tool or agency promises that adding llms.txt to Squarespace will rank your site in ChatGPT, get you cited by Gemini, or drive a set number of visitors, treat that as marketing, not evidence. The file costs nothing and takes minutes on 7.1 — judge it by whether AI tools describe your business correctly, not by a rank tracker.
