Priority fixes for decathlon.in

Ordered by impact and by how common each practice is among peers.

1. Priority 1 · Harden

   Framing restricted

   Observed: The homepage did not send frame-ancestors or X-Frame-Options, so other sites may frame it.

   Why it matters: Without it, another site can load your pages in a hidden frame and trick visitors into clicking buttons (clickjacking).

   What to do: Send Content-Security-Policy: frame-ancestors 'self' (or a list of trusted origins). X-Frame-Options: SAMEORIGIN covers older browsers.

   On Cloudflare: Add the header with a response header transform rule.

   70% of E-Commerce & Marketplaces peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

2. Priority 2 · Accelerate

   No render-blocking scripts in <head>

   Observed: The homepage <head> loaded 3 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.

   44% of E-Commerce & Marketplaces peers do this.

   Content Security Policy present

   Observed: The homepage response did not include a Content-Security-Policy header.

   48% of E-Commerce & Marketplaces peers do this.

4. Priority 4 · Harden

   X-Content-Type-Options: nosniff

   Observed: The homepage response did not include X-Content-Type-Options: nosniff.

   64% of E-Commerce & Marketplaces peers do this.
