Priority fixes for paypay.ne.jp
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
Modern image formats in use
Observed: The homepage had 72 images and none used WebP or AVIF.
Why it matters: WebP and AVIF are typically much smaller than JPEG or PNG at similar quality, and images are often the heaviest part of a page.
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 WordPress: WordPress has supported WebP uploads since 5.8 and AVIF since 6.5; image plugins or the host can convert existing images.
47% of Online Payment & Wallets peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.
Guide: AVIF, WebP, JPEG, and PNG: Choose the Right Image Format
Priority 2 · Harden
Framing restricted
Observed: The homepage did not send frame-ancestors or X-Frame-Options, so other sites may frame it.
What to do: Send Content-Security-Policy: frame-ancestors 'self' (or a list of trusted origins). X-Frame-Options: SAMEORIGIN covers older browsers.
On Amazon CloudFront: Set frame options in a response headers policy.
64% of Online Payment & Wallets peers do this.
Priority 3 · Accelerate
Offscreen images lazy-loaded
Observed: The homepage had 72 images and none used loading="lazy".
What to do: Add loading="lazy" to images below the fold. Do not lazy-load the main hero image, because that delays the largest visible element.
On WordPress: WordPress has added loading="lazy" to images by default since 5.5; check that your theme or a plugin has not removed it.
63% of Online Payment & Wallets peers do this.
Priority 4 · Harden
Certificate lifetime of 100 days or less
Observed: The certificate from GlobalSign nv-sa had a 199-day validity period, longer than the 100-day maximum that applies from March 2027.
What to do: Move to automated issuance and renewal now, while you still have time to test it.
44% of Online Payment & Wallets peers do this.
