Common fixes
- Missing security headers — add HSTS, X-Content-Type-Options, a Content-Security-Policy, and Referrer-Policy at your edge or app.
- Certificate expiring — renew before ~30 days out; automate with ACME/Let's Encrypt.
- Mixed content — serve all assets over HTTPS.
- SEO basics — give every page a unique title + meta description and a single H1.
