Frequently Asked Questions
Does SSL affect SEO rankings?▼
Yes, Google confirmed in 2014 that HTTPS is a ranking signal. Websites with valid SSL certificates receive a small ranking boost compared to HTTP-only sites. Additionally, Chrome marks non-HTTPS sites as "Not Secure" which can increase bounce rates.
What happens when an SSL certificate expires?▼
When an SSL certificate expires, browsers display a security warning to visitors, which dramatically increases bounce rate. Search engines may also stop crawling your site or flag it as insecure, hurting your rankings.
What is the difference between SSL and TLS?▼
TLS (Transport Layer Security) is the successor to SSL (Secure Sockets Layer). Modern websites use TLS 1.2 or 1.3, but the term "SSL" is still commonly used to refer to both. When people say "SSL certificate," they typically mean a TLS certificate.
Do I need SSL for my website?▼
Yes, SSL is essential for any website. It encrypts user data, is required for HTTPS (a Google ranking factor), prevents browser security warnings, and builds user trust. Most hosting providers and services like Let's Encrypt offer free SSL certificates.
