Why SSL certificates matter
Encryption & trust
SSL/TLS encrypts all data in transit between your server and visitors. Without it, login credentials, form submissions and payment data are exposed to anyone on the network.
Google ranking factor
Google confirmed HTTPS as a ranking signal in 2014. An expired or missing certificate not only harms user trust — it can also negatively affect your organic search visibility.
Browser warnings
Chrome, Firefox and Safari display a "Not secure" warning on all non-HTTPS pages. A visible security warning kills conversions and destroys first impressions instantly.
SSL certificates are the foundation of web security. They encrypt traffic between your visitors' browsers and your server, verify your domain identity and prevent man-in-the-middle attacks. Google has treated HTTPS as a ranking signal since 2014 and Chrome marks all HTTP pages as "Not secure". This free SSL checker analyses any website's certificate in real time: security grade (A+ to F), certificate validity, issuer organisation, expiry date, days remaining, TLS protocol version, HSTS enforcement and Subject Alternative Names. Useful for developers, system administrators and business owners who need a fast overview of their SSL configuration — no tools to install, no account required.
