Priority fixes for spacex.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Harden
HTTP requests move to HTTPS
Observed: A request to http://www.spacex.com/ was not redirected to HTTPS.
Why it matters: Visitors who type the address or follow an old link start on unencrypted HTTP. A redirect moves them to the encrypted site before any cookies or form data are sent.
What to do: Add a permanent (301 or 308) redirect from every http:// URL to the same https:// URL at your CDN, load balancer or web server.
On Cloudflare: Turn on Always Use HTTPS under SSL/TLS > Edge Certificates.
88% of Uncategorized peers do this. Limit: Measured for the homepage only, from one location, at the time of the check.
Priority 2 · Enable
robots.txt published
Observed: No robots.txt file was returned at the site root.
What to do: Publish /robots.txt with any crawl rules you need and a Sitemap: line pointing to your XML sitemap.
88% of Uncategorized peers do this.
