Pro Tip

Check your security headers grade at securityheaders.com — most sites score D or F. Getting an A grade takes 30 minutes of configuration and signals to Google that your site is well-maintained and trustworthy.

Warning

A hacked site receives a Google warning label in search results that destroys CTR overnight. Recovery takes weeks even after the hack is fixed. Prevention is 100x cheaper than recovery.

Step-by-Step Guide

1

Test current security headers at securityheaders.com

Go to securityheaders.com, enter your URL, and review your grade. It checks for all recommended security headers and tells you exactly which ones are missing. Aim for at least a B grade.

2

Implement recommended security headers

Add these headers to your server configuration (Apache .htaccess, Nginx config, or Cloudflare). The AI prompt for this task generates the exact configuration for your server type.

  • Strict-Transport-Security: max-age=31536000; includeSubDomains (forces HTTPS)
  • X-Content-Type-Options: nosniff (prevents MIME-type sniffing)
  • X-Frame-Options: SAMEORIGIN (prevents clickjacking)
  • Content-Security-Policy: default-src 'self' (controls resource loading)
  • Referrer-Policy: strict-origin-when-cross-origin (limits referrer data)
3

Set up Google Search Console security alerts

Search Console automatically alerts you about security issues. Go to Security & Manual Actions > Security Issues to check for any current problems. Ensure your email notifications are enabled in Settings > Users and permissions.

4

Keep CMS, plugins, and themes updated

In WordPress: enable auto-updates for minor releases (Settings > Updates). Manually review major updates. Delete unused plugins and themes — they're attack vectors even when deactivated. Use Wordfence or Sucuri for real-time protection.

5

Run regular malware scans

Use Sucuri SiteCheck (sitecheck.sucuri.net) for free external scanning. For WordPress, install Wordfence and run weekly scans. Set up Google Safe Browsing alerts. Check Search Console > Security Issues monthly.
