How to add llms.txt to Squarespace
Squarespace doesn't allow root-file uploads. Use a URL mapping + a stripped page, or front the domain with Cloudflare for full header control.
Before you start
- ✓Business plan or higher (for URL mappings)
- ✓Site admin access
- ✓Optional: Cloudflare account for the most reliable approach
Install in 4 steps
- 1
Create a page with slug 'llms-txt'
Use a blank layout. Paste your Markdown into a code block.
- 2
Add a URL mapping
Settings → Advanced → URL Mappings: '/llms.txt -> /llms-txt 301'.
- 3
Strip the chrome
Apply a custom CSS rule that hides header/footer for this page (.collection-llms-txt header, .collection-llms-txt footer { display:none }).
- 4
Verify
Fetch with curl. If Squarespace still wraps it in HTML, route through Cloudflare and rewrite the response.
Troubleshooting
Squarespace returns text/html for everything. Front the domain with a Cloudflare Worker that rewrites Content-Type to text/plain.
Personal plans don't support URL mappings. Upgrade to Business or set up Cloudflare in front.
Common gotchas
- • Squarespace returns text/html for everything — Cloudflare Workers can rewrite to text/plain
- • Personal plans don't support URL mappings — upgrade or use Cloudflare

Frequently asked questions
Does Squarespace need both llms.txt and robots.txt?
Yes. robots.txt grants crawler permission; llms.txt curates which pages matter. Together they form the minimum AI-search setup on any Squarespace site.
Will adding llms.txt slow down my site?
No. It's a tiny static text file fetched once and cached aggressively. Page-load impact is effectively zero.
How often should I update llms.txt?
Whenever your canonical content set changes — new docs section, new product line, new pricing page. A monthly review is a sensible cadence for most sites.
Can I see whether AI engines read my llms.txt?
Check your server logs for user agents like GPTBot, ClaudeBot, PerplexityBot, and Google-Extended hitting /llms.txt. Most sites see traffic within days of publishing.
