Frequently Asked Questions
What is an SSL certificate?
An SSL (Secure Sockets Layer) certificate encrypts data transmitted between a website and its visitors. It enables HTTPS, showing a padlock icon in browsers and protecting sensitive information like passwords and payment details.
Why does SSL matter for SEO?
Google uses HTTPS as a ranking signal. Websites with valid SSL certificates may rank higher in search results. Additionally, browsers display security warnings for non-HTTPS sites, which can drive visitors away.
What do the SSL grades mean?
Grades range from A+ (excellent) to F (failing). An A or A+ indicates strong security configuration. B grades suggest minor improvements needed. C and below indicate significant security concerns that should be addressed.
How often should I check my SSL certificate?
Check your SSL certificate monthly or whenever you make server configuration changes. Most certificates expire annually, so monitoring expiration dates helps prevent service interruptions.
