Priority fixes for nippon.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
Static files cached for 30 days or more
Observed: A same-site stylesheet or script was cacheable for no max-age, short of the 30-day benchmark.
Why it matters: Returning visitors and later page views reuse cached files instead of downloading them again.
What to do: Give versioned (fingerprinted) CSS, JavaScript, fonts and images Cache-Control: public, max-age=31536000, immutable, and change the file name whenever the content changes.
60% of News & Media peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.
Priority 2 · Accelerate
No render-blocking scripts in <head>
Observed: The homepage <head> loaded 6 external scripts without async or defer.
What to do: Add defer to scripts that need the DOM, async to independent ones such as analytics, or move them to the end of the body.
42% of News & Media peers do this.

Priority 3 · Enable
At most one redirect to the homepage
Observed: The homepage was reached after 2 redirects.
What to do: Point every alternate address (http, www or apex, old paths) straight to the final URL in a single redirect.
>99% of News & Media peers do this.
Priority 4 · Enable
Structured data present
Observed: The homepage had no JSON-LD structured data.
What to do: Add JSON-LD for your organization and main content types, then test it with Google's Rich Results Test.
76% of News & Media peers do this.
