Adding llms.txt to Squarespace

On Squarespace 7.1, llms.txt is a text field in your SEO settings. “You can create an llms.txt file on version 7.1 sites”, and “the llms.txt file is disabled by default” until you add text (Squarespace’s llms.txt help article). Squarespace does not write the content for you, so you need the text first.

How do you turn it on?

1. Make the text. Run your site through the llms.txt generator, edit the descriptions, and copy the result.
2. Open the setting. In Squarespace, open the SEO/AI Visibility panel, click SEO Settings, then the LLMS.txt tab.
3. Paste and save. Paste the text into the field and click Save.
4. Check it live. Open https://yourdomain.com/llms.txt, or run that address through the validator.

To switch it off again, go back to the same tab, click Delete, then Save. Squarespace itself says it cannot advise on the content, because llms.txt is “a proposed standard that’s still actively in development”.

What about Squarespace 7.0?

Squarespace describes the setting for version 7.1 sites only. If you cannot find the LLMS.txt tab, check which version your site runs before anything else.

Is it the same as blocking AI crawlers?

No. Squarespace has a separate checkbox, Block known artificial intelligence crawlers, under Settings then Crawlers. It adds rules to your robots.txt, and Squarespace notes that the request “doesn’t guarantee they will” comply (Squarespace’s article on AI crawlers).

So the checkbox mostly blocks training, and leaves the main AI search crawlers alone. If you want finer control than one checkbox, the robots.txt examples show the rules, though Squarespace manages the file itself. Whatever you choose, keep the two consistent: an AI tool that obeys robots.txt will not read pages it is blocked from, whatever your llms.txt lists.
