Priority fixes for bestflashcard.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Harden
DMARC policy enforces quarantine or reject
Observed: No DMARC record was found at _dmarc.bestflashcard.com.
Why it matters: An enforcing DMARC policy helps receiving mail systems reject email that falsely claims to come from your domain, a common route for phishing your customers.
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.
36% of Education & Online Learning peers do this. Limit: Read from public DNS at the time of the check; records may have changed since.
Priority 2 · Accelerate
Modern image formats in use
Observed: The homepage had 188 images and none used WebP or AVIF.
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 Cloudflare: Cloudflare Polish can convert images to WebP.
32% of Education & Online Learning peers do this.

Priority 3 · Accelerate
No render-blocking scripts in <head>
Observed: The homepage <head> loaded 5 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 Education & Online Learning peers do this.
Guide: Control Third-Party Scripts Before They Control Your Page
Priority 4 · Accelerate
Offscreen images lazy-loaded
Observed: The homepage had 188 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.
52% of Education & Online Learning peers do this.
