- lowVery little text in the raw HTML71 words. Thin for both humans and machines.
- lowNo llms.txtOptional, but a short curated index at /llms.txt is the cheapest way to tell assistants what matters on this site.
- infoCanonical points elsewhereCanonical is https://www.bing.com/. Indexes will credit that URL, not this one.
