An honest limit
Whether an assistant cites a page is up to the assistant. Being easy to read is up to the site.
Structured dataThe page says what it is.
The page says what it is.
Article, product or page.
The template knows what a page is, and the structured data follows from the record. Nothing to paste, nothing to keep in sync.

Questions
What is AEO?
Answer engine optimization: making a site easy for AI assistants to read and quote, the way SEO makes it easy for search engines to list.
Will AI assistants cite my site?
That is up to the assistant. What a site can do is be easy to read: plain static HTML, structured data and an llms.txt summary. Every Tandmade site has all three.
Do I have to write llms.txt?
No. It is built from your pages and published content and updates with them. You can add a summary line, or replace the whole file with your own.
Can I stop AI companies from training on my site?
Yes. One switch in Site settings blocks the crawlers that collect training data. AI search can still find and cite your pages.
What about pages I hide from search?
A hidden page leaves the sitemap and llms.txt as well.
