SSL certificates are mandatory for modern websites. Google considers HTTPS a ranking factor, and browsers warn users about unsecured sites. Proper SSL configuration protects user data and boosts search engine trust.

HTTPS ensures accurate referral data and prevents analytics data loss from secure sites.

⚡ Performance Benefits

Modern SSL supports HTTP/2, which can actually improve page load speeds.

Frequently Asked Questions

What is an SSL certificate and why is it important?

An SSL certificate encrypts data transmitted between a user's browser and your web server, protecting sensitive information like passwords and payment details. Websites with SSL display a padlock icon and use HTTPS. Google has confirmed HTTPS as a ranking signal, and browsers mark sites without SSL as "Not Secure," which can drive away visitors.

How can I tell if my SSL certificate is about to expire?

Our SSL checker shows the exact expiration date of your certificate along with a warning if it expires within 30 days. Expired SSL certificates cause browser security warnings that block visitors from accessing your site. Setting up automated monitoring and renewal through your hosting provider or certificate authority prevents unexpected expirations.

Does SSL affect my website's SEO performance?

Yes, HTTPS is a confirmed Google ranking factor. Sites with valid SSL certificates receive a minor ranking boost over HTTP-only sites. Beyond rankings, SSL improves user trust and is required for modern browser features like service workers, geolocation APIs, and HTTP/2, all of which contribute to better site performance and user experience.
