Squarespace: vendor profile

In short

Squarespace generates structured data and the sitemap, and owners can edit neither. Its llms.txt stays off until an owner types text into the SEO Settings tab, and support will not advise on the contents. A checkbox adds robots.txt rules for 26 named AI crawlers, sitewide. Basic costs $12 a month paid annually.
