Priority fixes for comic-days.com
Ordered by impact and by how common each practice is among peers.
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.
91% of Online Publishing peers do this. Limit: Only the standard location was requested, once, at the time of the check.

Priority 2 · 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.
79% of Online Publishing peers do this.

Priority 3 · 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.
On Amazon CloudFront: Attach a response headers policy with Strict-Transport-Security to each distribution.
27% of Online Publishing peers do this.
Priority 4 · Accelerate
Modern image formats in use
Observed: The homepage had 492 images and none used WebP or AVIF.
What to do: Serve WebP or AVIF with a JPEG or PNG fallback, either through an image CDN or by generating both formats at build time.
On Next.js: The next/image component serves optimized formats automatically.
38% of Online Publishing peers do this.
