In the modern digital landscape, website security is no longer optional. When you check if site is secure https, you are verifying that the communication between a user's browser and the web server is encrypted. Without HTTPS, sensitive data like passwords, credit card numbers, and personal information are sent in plain text, making them easy targets for "man-in-the-middle" attacks.
HTTP (Hypertext Transfer Protocol) is the foundation of data exchange on the web, but it lacks a security layer. HTTPS (Hypertext Transfer Protocol Secure) adds a layer of encryption using an SSL/TLS certificate. Our SSL checker helps you identify if this layer is active. Beyond security, HTTPS provides data integrity, ensuring that the content hasn't been tampered with during transit.
Using tools like our Meta Description Length Checker or Broken Link Checker is great for SEO, but security is the foundation upon which all other SEO efforts are built.
Google officially announced HTTPS as a ranking signal back in 2014. If two websites are equal in content quality and authority, the one with a secure connection will likely rank higher. Furthermore, modern browsers like Google Chrome now display a "Not Secure" warning for sites using HTTP, which can drastically increase your bounce rate and decrease user trust.
Sometimes a site has an SSL certificate, but it still shows security warnings. This is often due to "Mixed Content"—where the main page loads over HTTPS, but resources like images, scripts, or stylesheets load over HTTP. Our mixed content checker logic helps you understand that even if the protocol says HTTPS, every single asset must be secure to maintain the padlock icon.
If you are migrating a site to HTTPS, you might also want to use our Redirect Checker to ensure your old HTTP pages are correctly forwarding to the new secure versions.
https:// prefix.An SSL (Secure Sockets Layer) certificate is a digital certificate that authenticates a website's identity and enables an encrypted connection. It protects the data flowing between the user and the server.
Yes! Organizations like Let's Encrypt provide free SSL certificates that are recognized by all major browsers. Most modern web hosts offer one-click installation for these free certificates.
If your certificate expires, browsers will display a large warning to users stating that the connection is not private. This usually results in a massive drop in traffic and trust.
