Frequently Asked Questions
Q: What is an SSL certificate?
A: An SSL certificate is a digital certificate that authenticates a website's identity and enables an encrypted connection. Websites with SSL use HTTPS instead of HTTP.
Q: Does SSL affect Google rankings?
A: Yes. Google uses HTTPS as a ranking signal. Websites without a valid SSL certificate may rank lower and browsers will show a "Not Secure" warning.
Q: When should I renew my SSL certificate?
A: Renew before it expires. Most certificates are valid for 90 days to 1 year. This tool shows the expiry date so you can plan renewal in advance.
