LLM optimization signals

What these signals are

Beyond how visible you are in AI answers, LumaRank checks a handful of technical signals on your own website. These are the things that make it easy (or hard) for AI assistants to find your pages, read them, and describe your brand accurately. Getting them in place gives the assistants cleaner material to work from.

The signals we look for

• llms.txt and ai.txt: simple files that point AI systems to the content you want them to rely on when describing your brand.
• robots.txt and sitemap.xml: the basics that let crawlers (including AI bots) reach and discover all of your pages.
• Structured data (JSON-LD): machine-readable markup that spells out what each page is about, so assistants don't have to guess.
• OpenGraph tags: metadata that gives a clean title, description and image for each page.
• RSS feed: a steady feed of your latest content, which helps systems stay current.
• Documentation, API reference and a help center: in-depth, well-structured content that assistants lean on to explain how your product actually works.

How to read the card

The card shows which signals are present on your site and rolls them up into two readouts: one for your structured, machine-readable metadata and one for the depth of your documentation. A higher reading means assistants have more, and cleaner, material to represent you accurately. Use the See example links to view a concrete sample of each file or tag.

What to do about it

• Start with anything marked as missing: those are usually the quickest wins.
• Prioritise structured data and a complete sitemap; they have the broadest impact.
• If you publish docs or a help center, make sure they're easy to reach and well organized.

These signals support, but don't replace, your AI Visibility score and your off-site presence: the first is how AI talks about you, the second is what the web says, and these are how legible your own site is to the assistants.
