What Is an SSL Certificate and Why It Matters

An SSL certificate encrypts data between the user's browser and the site server. Sites with SSL work over HTTPS — a padlock icon appears in the browser address bar.

What This Tool Checks

  • HTTPS availability — whether the site works over the secure protocol
  • Connection correctness — whether the SSL connection is established without errors
  • Validity period — when the certificate expires and how many days remain
  • Issuer — who issued the certificate (Let's Encrypt, GlobalSign, etc.)

Why HTTPS Is Important for SEO

Google considers HTTPS for ranking. Sites without an SSL certificate may lose positions in search results. Additionally, browsers mark HTTP sites as "Not Secure," which reduces user trust.

How to Get an SSL Certificate

  • Let's Encrypt — free certificate with automatic renewal
  • Hosting provider — many hosts offer free SSL
  • Paid certificates — GlobalSign, Comodo, DigiCert — for organizations requiring extended validation

Frequently Asked Questions

What happens if the SSL certificate expires? ▶
Browsers will show a "Your connection is not private" warning and most users will leave the site. Search engines may also lower the site's rankings.
How often does the certificate need to be renewed? ▶
Depends on the type. Let's Encrypt certificates are valid for 90 days and renew automatically. Paid certificates are typically issued for 1 year.
Is free SSL worse than paid? ▶
In terms of encryption, no — the protection level is the same. Paid certificates offer extended validation (EV) — the organization name appears in the address bar. For most sites, free Let's Encrypt is sufficient.
