leaderboard scorecard · scored flat-pool-v1 · updated 2026-08-04

How well do agents see the web?

Most of the web was built for human eyes. AI agents (coding assistants, research bots, autonomous tools) have to fetch the same pages and pull meaning out of layout-driven HTML, JavaScript-rendered widgets, cookie walls, and broken markdown. The a14y scorecard turns that effort into a number: how many of 38 machine-readability checks a site passes, from llms.txt through AGENTS.md down to canonical headers and breadcrumb JSON-LD. The leaderboard below ranks a cross-section of sites by that score; the insights underneath show how we're evolving to a more agent-readable web.

Score distribution

How are the 321 scores distributed across the catalog? Each bar counts the sites whose overall score falls in that 10-point bucket. Most sites cluster between 40 and 70: the long climb to a high score starts only once a site ships llms.txt, an AGENTS.md, and a markdown sitemap, the three site-level checks that a single template change can flip from failing to passing.

Mean score by category

Docs platforms tend to score the highest because their authors think hardest about machine consumers; many already ship llms.txt and an AGENTS.md. Consumer sites like news, retail, and reference sit at the bottom: they were built for human eyes, hide content behind cookie banners and JavaScript, and rarely surface the machine-readable signals an agent needs to navigate them.

Hardest checks to pass

For each check id, the percentage of sites where the check fully passed (every occurrence across every page returned pass). Sorted hardest first; filtered to checks applicable to ≥5 sites. The pile-up of zeroes and single-digit pass rates near the top is the most actionable list on this page: they're the cheapest scorecard wins every site is leaving on the table.

How this leaderboard is built

Scoring

Every site is scanned with the open-source a14y CLI pinned to scorecard v0.3.0-draft. Each site gets one site-mode crawl (≤50 pages, polite-delayed) or a single page-mode audit for very large consumer sites where crawling every page would be wasteful or hostile. The score is the simple ratio passed / applicable across every check on every page, the same number the CLI prints when you run it locally, so a site owner's local result matches the leaderboard exactly.

Catalog

The site list is hand-curated with deliberate ratios: at least half are technical documentation platforms (React, Stripe, AWS, etc.); at least a quarter are non-developer SaaS dashboards and help centers (Notion, Slack, Atlassian help); the rest are major consumer sites (Wikipedia, news, retail) audited in page mode so a single scan stays bounded. Want yours included? Open an issue.

Versioning

Scores from different scorecard versions are not directly comparable. When we ship a new scorecard version, every site is re-scanned against it before this page updates, so the leaderboard you're reading today compares apples to apples even as the scorecard itself evolves over time.
