Priority fixes for suumo.jp
Ordered by impact and by how common each practice is among peers.
Priority 1 · Enable
Mobile viewport configured
Observed: The homepage had no viewport meta tag, so phones may render it zoomed out.
Why it matters: Without it, phones render the page at desktop width and shrink it, which makes text tiny and hard to use.
What to do: Add <meta name="viewport" content="width=device-width, initial-scale=1"> and check the layout on small screens.
94% of Real Estate & Property Listings peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.
Priority 2 · Accelerate
HTTP/2 negotiated
Observed: The TLS handshake selected HTTP/1.1 instead of HTTP/2.
What to do: Enable HTTP/2 on your CDN or server. Most CDNs do this by default.
91% of Real Estate & Property Listings peers do this.
Priority 3 · Harden
TLS 1.3 negotiated
Observed: The TLS connection negotiated TLSv1.2.
What to do: Enable TLS 1.3 on your CDN or server. Keep TLS 1.2 available for older clients unless you have checked your audience.
89% of Real Estate & Property Listings peers do this.
Priority 4 · 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.
On WordPress: WordPress has generated a basic sitemap at /wp-sitemap.xml since 5.5; SEO plugins can replace it.
74% of Real Estate & Property Listings peers do this.
