Priority fixes for windy.com

Ordered by impact and by how common each practice is among peers.

  1. Priority 1 · Enable

    robots.txt published

    Observed: No robots.txt file was returned at the site root.

    Why it matters: robots.txt is where crawlers look first for crawl rules and sitemap locations. Without it, they assume everything is open.

    What to do: Publish /robots.txt with any crawl rules you need and a Sitemap: line pointing to your XML sitemap.

    90% of Weather Forecast peers do this. Limit: Only the standard location was requested, once, at the time of the check.

  2. Priority 2 · Harden

    HSTS kept for at least a year

    Observed: The homepage response did not include a Strict-Transport-Security header.

    What to do: Send Strict-Transport-Security on HTTPS responses. Start with a short max-age (for example 300 seconds), confirm every subdomain works over HTTPS, then raise it in steps to 31536000. Add includeSubDomains only when all subdomains are HTTPS. HSTS preload is optional and hard to undo; hstspreload.org itself does not recommend it by default.

    39% of Weather Forecast peers do this.

  3. Priority 3 · Enable

    XML sitemap discoverable

    Observed: No sitemap was listed in robots.txt or found at /sitemap.xml.

    What to do: Generate an XML sitemap of canonical URLs, reference it in robots.txt and submit it in Google Search Console.

    66% of Weather Forecast peers do this.

  4. Priority 4 · Harden

    X-Content-Type-Options: nosniff

    Observed: The homepage response did not include X-Content-Type-Options: nosniff.

    What to do: Send X-Content-Type-Options: nosniff on all responses and make sure each file is served with the correct Content-Type.

    46% of Weather Forecast peers do this.
