Publicly-generated scan via agentspeed.com. Not affiliated with weather.com.

weather.com is solidly ready for AI agents (composite 86, grade B). Strongest sub-score: performance (100). Weakest: discoverability (73). The most actionable gaps detected: no markdown content negotiation.

Governance & crawler policy

How weather.com declares its policy toward AI agents and crawlers. These rows are a presentation view over checks already counted under Discoverability and Readability, so they don’t add to the composite a second time.

robots.txt partially restricts AI agents: some pass, some are blocked. Run the live matrix below for a per-agent verdict.

For a live UA-by-UA fetch matrix (status, redirects, content similarity, cloaking detection across GPTBot, ChatGPT-User, ClaudeBot, Claude-User, PerplexityBot, Google-Extended, Googlebot, Bingbot, CCBot, and a default browser), run the matrix tool against this domain.

robots.txt advertises Content-Signal directives (e.g. `Content-Signal: ai-train=no, ai-summarize=yes`) that let agents respect granular usage preferences.

Requests with `Accept: text/markdown` return a markdown representation of the page (Markdown content negotiation).

weight 0

The page exposes WebMCP (in-browser Model Context Protocol) so on-page agents can invoke tools without leaving the tab.

What we looked for

robots.txt does not disallow answer-time AI access agents (ChatGPT-User, OAI-SearchBot, Claude-User, Claude-SearchBot, PerplexityBot, Perplexity-User, YouBot, Amazonbot). Training-data crawler blocks (GPTBot, CCBot, Google-Extended, …) are reported as informational and never fail the check.

AgentSpeed didn't find a non-empty <title>, or it was over the recommended limit. Agents cite the title verbatim when they reference the page; an empty or boilerplate title becomes the citation.

FAQ
What does this AgentSpeed score mean?expand ›

The composite is a 0–100 weighted average of five sub-scores measuring how well a website performs for AI agents (ChatGPT, Claude, Perplexity, Operator, etc.). The full rubric (every check, weight, and grade band) is published at /rubric.

Is this an official score from the website owner?expand ›

No. AgentSpeed scores are publicly generated against weather.com's public surfaces (robots.txt, sitemap, the landing URL, /llms.txt, /.well-known/* discovery endpoints). AgentSpeed is not affiliated with or endorsed by weather.com. The score reflects what we observed at scan time, nothing more.

How often is this site scanned?expand ›

Public scans happen when someone submits the URL on the homepage. Once a domain is claimed in the (forthcoming) monitoring tier, the site is rescanned daily and a history is kept. For now, every public score reflects the most recent submission.

How can this score be improved?expand ›

Each failing check on the page expands to a remediation step with the exact change to make. The "Top fixes" section ranks them by score impact. Most domains move 5–10 points by adding an llms.txt, allowing well-known agent user-agents in robots.txt, and emitting JSON-LD that matches the page purpose.

What rubric version was used?expand ›

This scan was computed against rubric r2026.11.0. The rubric is versioned and immutable: historical scans always render against the rubric they were computed on, even after a new version ships. The current rubric and its full changelog are at /rubric.
