FIX
7 issues found across 199 images
Warning::
55 images significantly larger than display size
Resizing to display dimensions could save approximately 0 KB.
Got: ~0 KB wasted
Warning::
198 images missing explicit width/height
Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
Info::
63 below-fold images missing loading="lazy"
Lazy loading defers below-fold images, reducing initial page weight.
Info::
180 of 199 images use legacy formats
Warning::
1 above-fold image(s) marked loading="lazy" (LCP anti-pattern)
Above-fold images marked lazy delay LCP -- the browser waits for the IntersectionObserver to fire before fetching, even though the image is in the initial viewport. Remove `loading="lazy"` on above-the-fold images (especially the LCP candidate). Sample: https://vcdn1-vnexpress.vnecdn.net/2026/08/28/nfnbngphamthuhang1-1787911561-7693-1787911578.jpg?w=680&h=408&q=100&dpr=1&fit=crop&s=T4UMQoUwEe2In6ITFvDZVg.
Info::
10 image(s) wider than 400px without srcset (no responsive serving)
These images deliver the same asset to every viewport (mobile, tablet, retina). Adding srcset / <picture> lets the browser pick a viewport-appropriate variant and typically saves 40-70% of bytes on mobile. Sample: https://s1cdn.vnecdn.net/vnexpress/restruct/i/v9905/banner/banner_quockhanh_pc.png, https://i.ebox.com.vn/2024/05/13/1b375ee1_1715590165.jpg?w=500&h=300&q=100&dpr=1&rt=fit&g=no&s=YxAUwXGzljsVnk0TiOFqBg, https://i.ebox.com.vn/2025/10/08/8134744b_1759918539.jpg?w=500&h=300&q=100&dpr=1&rt=fit&g=no&s=ewb6HxjyVLssC-59FJmy_Q (+7 more).
Info::
4 image(s) rendered at a different aspect ratio than the source
The displayed dimensions distort the source -- CSS is forcing the image into a container at the wrong ratio, producing visible stretching or squashing. Either crop the source to match or use object-fit: cover (and accept the crop). Sample: https://vcdn1-vnexpress.vnecdn.net/2026/08/28/e989b6c0ff7c7e22276d1787734932-2589-5715-1787875141.webp?w=300&h=180&q=100&dpr=1&fit=crop&s=IkPPNew-oiC4ZDciFt-WLQ, https://vcdn1-vnexpress.vnecdn.net/2026/08/27/thumbngang-1787800982-5436-1787801123.png?w=300&h=180&q=100&dpr=1&fit=crop&s=2I6mGJD_yrnROhRz07DGiQ, https://vcdn1-vnexpress.vnecdn.net/2026/08/26/thumbtccn16X92-1787718898-8187-1787718970.png?w=300&h=180&q=100&dpr=1&fit=crop&s=z1Gx3qg5s0PTlswKjqfYug (+1 more).

Critical::
og:image is not reachable
The og:image URL could not be fetched. Social platforms won't be able to display it.
Got: https://s1cdn.vnecdn.net/vnexpress/restruct/i/v9905/default/thumb_1000.jpg

The og:image URL could not be fetched. Social platforms won't be able to display it.

Why this matters

An unreachable og:image URL (404, DNS fail, slow timeout) means social platforms cache the failure and serve no image for hours.

Learn more

Social platforms (Facebook, Twitter) cache OG metadata aggressively — including failed image fetches. A momentarily-broken og:image can leave your shares imageless for hours. Test og:image URLs in Facebook's Sharing Debugger to force re-cache after fixing.

Missing recommended property "description" for WebSite
Adding "description" can improve how search engines display your content.
Info::
2 JSON-LD blocks found

Adding "description" can improve how search engines display your content.

Why this matters

Recommended schema properties unlock richer SERP layouts — without them you get the basic rich result instead of the enhanced one.

Learn more

Recommended properties expand what Google can render. E.g., adding aggregateRating to Product unlocks star ratings; adding image to Article unlocks the image-card variant. Each recommended property is a direct SERP-real-estate gain.

2 rich-result schema type(s) declared
Inventory of structured-data types on the page (each may unlock a different SERP feature): Organization, WebSite Search engines decide whether to render rich results based on content quality + page-level signals; declaring the schema is necessary but not sufficient.
