What happens when the SSL certificate expires?

The browser shows a full-page warning — "Your connection is not private" — that scares away most visitors. For e-commerce stores this means lost revenue. Google may also remove the HTTPS mark and rank the website lower.

How often should I check SSL?

At least once a month, and always 30 days before the expiry date. Most certificates last 90 days (Let's Encrypt) or 1 year (paid). Automatic renewal is ideal, but you should verify that it works.

What is the difference between DV, OV and EV?

DV (Domain Validation) only verifies domain ownership — fastest and cheapest. OV (Organization Validation) also verifies the organization. EV (Extended Validation) gives the highest validation with the organization name in the certificate. For most websites DV is sufficient.

Is Let's Encrypt as secure as paid certificates?

Yes, the encryption is identical. The difference is the validation level (DV vs. OV/EV) and support. Let's Encrypt is perfect for most websites. Paid certificates provide OV/EV validation that can increase trust for e-commerce and finance.

What it does

Verifies the SSL/TLS certificate — expiry date, issuer, protocol version and security status.

An expired SSL certificate gives visitors a scary warning and kills trust — but you discover it only when it is too late

SSL certificates are the foundation for secure communication on the web. When a certificate expires, the browser shows a full-page warning — "Your connection is not private" — that scares away 85% of visitors immediately. For e-commerce stores this means lost revenue for every hour the certificate is expired. The problem is that certificates expire silently — no alarm, no email, no notification — unless you actively monitor them.

Expired certificates scare visitors — the browser shows a full-page warning that makes 85% of visitors leave the website immediately, meaning lost traffic and revenue
Google penalizes insecure websites — websites without valid SSL rank lower in search results, and Chrome marks them as "Not Secure" in the address bar
Wrong configuration is invisible — a certificate can be valid but misconfigured (wrong domain, weak encryption, missing intermediate certificates) without you noticing
Multiple domains and subdomains increase complexity — when you have 5-10 domains with different certificates and expiry dates, it is easy to forget one

Instant SSL check showing certificate status, expiry date, encryption strength and configuration details

SSL Checker verifies the SSL/TLS certificate for a domain and shows all relevant information — expiry date, issuer, encryption algorithm, protocol version and whether the certificate chain is complete. You immediately see if the certificate is valid, when it expires and if it is configured correctly. Perfect for catching problems before they affect visitors.

Expiry date: see exactly when the certificate expires — with countdown in days so you know exactly how much time you have to renew
Certificate chain: verifies that the entire certificate chain is complete — from the domain certificate via intermediate certificates to the root certificate
Encryption strength: checks the encryption algorithm and key size — identifies weak configurations that should be upgraded
Protocol version: verifies that TLS 1.2 or 1.3 is used — older versions (TLS 1.0, 1.1, SSL 3.0) are insecure and should be disabled

Features

Certificate status: immediately see if the certificate is valid, expired or misconfigured — with clear green/red indicator
Expiry countdown: see exact number of days until the certificate expires — so you can plan renewal well in advance
Issuer info: see who issued the certificate (Let's Encrypt, DigiCert, Comodo, etc.) and certificate type (DV, OV, EV)
Security rating: get an overall security rating based on encryption, protocol, certificate chain and configuration — with concrete improvement suggestions

How it works

Enter the domain name you want to check — e.g. "example.com" or "shop.example.com"
The tool connects to the server and retrieves the SSL certificate — analyzes validity, expiry date, encryption and configuration
See the result with certificate status, expiry countdown, security rating and any issues that need to be fixed

Use cases

IT administrators monitoring SSL certificates for multiple domains who need to ensure none expire without renewal
SEO specialists checking SSL status as part of technical SEO audit — Google requires HTTPS for optimal ranking
E-commerce stores that must ensure the SSL certificate is always valid to maintain customer trust and avoid lost sales

Why use SSL Checker?

SSL is no longer optional — it is an absolute requirement. Google requires HTTPS for optimal ranking, browsers mark HTTP pages as "Not Secure", and visitors expect the padlock icon in the address bar. SSL Checker ensures your certificate is valid, correctly configured and not approaching expiry.

Expired certificates are one of the most common and costly technical errors. An e-commerce store that loses SSL for 4 hours on a Friday can lose hundreds of thousands in revenue. Regular checking with countdown to expiry gives you time to renew before it becomes a problem.

Misconfiguration is as dangerous as expiry. A certificate that is valid but configured with weak encryption, missing intermediate certificates or old TLS version gives false security. SSL Checker reveals these hidden problems and gives concrete improvement suggestions.
