Enforce HTTPS Sitewide — Step-by-Step Guide

SSL certificates are a trust signal. Redirect all HTTP to HTTPS. Check for mixed content warnings that break the padlock icon.

Pro Tip

The fastest free HTTPS setup is Cloudflare: just change your nameservers and enable "Always Use HTTPS" in one click. It also adds a CDN and DDoS protection as a bonus.

Warning

After migrating to HTTPS, monitor Search Console closely for 2-4 weeks. You may see a temporary traffic dip as Google re-indexes pages with the new protocol.

Step-by-Step Guide

1

Install SSL certificate (free via Let's Encrypt or Cloudflare)

Most hosting providers offer free SSL via Let's Encrypt. In cPanel: go to SSL/TLS > Manage SSL Sites. On Cloudflare: just enable "Always Use HTTPS" under SSL/TLS settings. On Netlify/Vercel: HTTPS is automatic.

  • cPanel hosting: Security > SSL/TLS Status > click "Run AutoSSL"
  • Cloudflare: Add your site, change nameservers, then SSL/TLS > set to "Full (strict)"
  • Manually via Certbot: Run "sudo certbot --nginx" or "sudo certbot --apache"

Add 301 redirects from HTTP to HTTPS

Force all HTTP traffic to HTTPS. In Apache .htaccess: RewriteEngine On, RewriteCond %{HTTPS} off, RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]. In Nginx: add "return 301 https://$server_name$request_uri;" in the server block for port 80.

3

Update all internal links to HTTPS

Search your database or codebase for "http://" references to your own domain and replace with "https://". In WordPress, use the Better Search Replace plugin. For other CMSes, do a database find-and-replace.

4

Check for mixed content with browser dev tools

Open Chrome DevTools (F12) > Console tab. Look for "Mixed Content" warnings. These occur when an HTTPS page loads resources (images, scripts, CSS) over HTTP. Fix each one by updating the resource URL to HTTPS.

5

Update sitemap and canonical URLs to HTTPS

Regenerate your XML sitemap to use https:// URLs. Check that all canonical tags reference https://. Update your Search Console property to the HTTPS version (or use a Domain property which covers both).
