Certbot is a free, open-source software that allows you to automate the SSL certification process and secure your web server with HTTPS. It’s developed by the Electronic Frontier Foundation (EFF) and supports a wide range of web servers, including Nginx, Apache, and others. Certbot simplifies the SSL certificate issuance and renewal process by automatically verifying your domain ownership and requesting, installing and configuring SSL certificates for your website.
1. How does Certbot work?
When you request SSL certification for your website, certbot contacts the Let’s Encrypt certificate authority and obtains a certificate for your domain.

Additionally, SSL certification is also important for SEO, as search engines give priority to secure websites over those that aren’t.
