Priority fixes for tiengdong.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
Modern image formats in use
Observed: The homepage had 12 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.
46% of Stock Image & Video Libraries peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.

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.
On WordPress: WordPress has generated a basic sitemap at /wp-sitemap.xml since 5.5; SEO plugins can replace it.
62% of Stock Image & Video Libraries peers do this.

Priority 3 · Accelerate
No render-blocking scripts in <head>
Observed: The homepage <head> loaded 4 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.
On WordPress: Since WordPress 6.3, scripts can be registered with a defer or async loading strategy.

Priority 4 · Harden
DMARC policy enforces quarantine or reject
Observed: No DMARC record was found at _dmarc.tiengdong.com.
What to do: Publish DMARC with p=none and a reporting address first, fix any legitimate senders that fail SPF or DKIM alignment, then move to quarantine and finally reject.
42% of Stock Image & Video Libraries peers do this.
