Findings, biggest first

Each finding shows the points it would add to the score once fixed.

  1. Finding 1

    Add real copy to the page

    Content, about 1 hour

    Readable text is a tiny share of the page's code, or there's very little of it. Crawlers summarise words, not markup.

    +4points
  2. Finding 2

    Offer a machine-readable interface

    Interface, needs a developer

    A valid /openapi.json or /llms-full.txt lets AI agents use your product or read your docs in full, not just your homepage.

    +4points
  3. Finding 3

    Add an llms.txt file

    Access, about 1 hour

    A short Markdown summary of your site at /llms.txt. Cheap to add, but few AI systems request it yet, so it's worth 3 points.

    +3points
  4. Finding 4

    Mirror llms.txt at /.well-known/llms.txt

    Access, about 5 min

    Some tools look in the .well-known folder instead. A copy of the same file covers both.

    +1points
