SSL Certificates Explained

That padlock icon in your browser? Here's what SSL does, why you need it, and how to get it for free.

What Is SSL/TLS?

SSL (Secure Sockets Layer) and its successor TLS encrypt the connection between visitors and your website.

With SSL: https://example.com (đź”’ padlock)

Without SSL: http://example.com (⚠️ "Not Secure")

Why SSL Matters

Security

Encrypts data in transit—passwords, credit cards, and personal info can't be intercepted.

Trust

Browsers show "Not Secure" warnings for sites without SSL. Visitors bounce.

SEO

Google uses HTTPS as a ranking signal. Non-SSL sites rank lower.

Free vs Paid SSL

Type Cost Best For
Let's Encrypt (DV) FREE Most websites
Cloudflare SSL FREE If using Cloudflare
OV Certificate $50-200/yr Business verification
EV Certificate $100-500/yr Banks, enterprise

For most sites: Free Let's Encrypt or Cloudflare SSL is all you need. The encryption is identical.

How to Get SSL

  • Hosting providers: Most include free SSL (Netlify, Vercel, cPanel hosts)
  • Cloudflare: Free plan includes SSL for any site
  • Website builders: Squarespace, Wix, etc. include SSL automatically
  • Let's Encrypt: Free, requires setup on your server (Certbot)

Bottom Line

Every website needs SSL. It's free. There's no excuse not to have it in 2025.

If your host doesn't provide free SSL, put Cloudflare in front of your site.
