Priority fixes for ticketmaster.co
Ordered by impact and by how common each practice is among peers.
Priority 1 · Harden
HSTS kept for at least a year
Observed: The homepage response did not include a Strict-Transport-Security header.
Why it matters: HSTS tells browsers to use HTTPS for your host on every later visit, which removes the window where a first HTTP request can be intercepted.
What to do: Send Strict-Transport-Security on HTTPS responses. Start with a short max-age (for example 300 seconds), confirm every subdomain works over HTTPS, then raise it in steps to 31536000. Add includeSubDomains only when all subdomains are HTTPS. HSTS preload is optional and hard to undo; hstspreload.org itself does not recommend it by default.
On Fastly: Add the header in VCL or a header rule as described in Fastly's HSTS guide.
42% of Events & Online Ticketing peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.
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.
64% of Events & Online Ticketing peers do this.

Priority 3 · Enable
Canonical URL declared
Observed: The homepage did not declare a canonical URL.
What to do: Add a self-referencing canonical link to every indexable page, using the final https:// URL.
65% of Events & Online Ticketing peers do this.
Priority 4 · Accelerate
No render-blocking scripts in <head>
Observed: The homepage <head> loaded 2 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.
35% of Events & Online Ticketing peers do this.
