Frequently Asked Questions

What is an SSL certificate and why is it important?
An SSL certificate is a digital certificate that encrypts data communication between your website and its visitors. It ensures user data security, increases trust in your site, and provides advantages in Google rankings.
Can I publish a website without an SSL certificate?
While technically possible, it's not recommended. Modern browsers mark sites without SSL certificates as insecure, which negatively impacts visitor trust and SEO rankings.
When does my SSL certificate expire?
You can instantly check your certificate's validity period, start and end dates by entering your domain address in our SSL checker system.
What is a Wildcard SSL certificate?
A Wildcard SSL certificate covers both the main domain and all its subdomains. For example: a *.domain.com certificate is valid for all subdomains like blog.domain.com, shop.domain.com.
How do I renew my SSL certificate?
It's recommended to start the renewal process 30 days before your certificate expires. Contact your certificate provider or hosting company for renewal support.
