Priority fixes for sympla.com.br
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
No render-blocking scripts in <head>
Observed: The homepage <head> loaded 1 external script without async or defer.
Why it matters: A plain <script src> in the head stops the browser from showing anything until that file has downloaded and run.
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 Next.js: Use the next/script component with an appropriate loading strategy.
35% of Events & Online Ticketing peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.
Guide: Control Third-Party Scripts Before They Control Your Page
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 Cloudflare: Add the header with a response header transform rule.
52% of Events & Online Ticketing peers do this.
Priority 3 · Enable
Structured data present
Observed: The homepage had no JSON-LD structured data.
What to do: Add JSON-LD for your organization and main content types, then test it with Google's Rich Results Test.
51% of Events & Online Ticketing peers do this.
Priority 4 · Harden
X-Content-Type-Options: nosniff
Observed: The homepage response did not include X-Content-Type-Options: nosniff.
What to do: Send X-Content-Type-Options: nosniff on all responses and make sure each file is served with the correct Content-Type.
On Cloudflare: Add the header with a response header transform rule.
47% of Events & Online Ticketing peers do this.
