Common SSL Issues to Watch For

- Certificates installed on the wrong domain or subdomain

How SSL Affects SEO and User Experience
HTTPS is now the standard for any website. Not only does it protect your users’ data, but it also impacts your search visibility. According to Ahrefs, switching to HTTPS can improve rankings and increase trust signals. Websites without SSL often see higher bounce rates because visitors don’t feel safe.
Checking your SSL regularly ensures you maintain a secure, trustworthy site.
When to Test Your SSL Certificate
You should run an SSL check when you:
- Install a new SSL certificate or renew an existing one
- Launch a new website or migrate to HTTPS
- Notice security warnings in browsers
- Update server configurations or hosting providers
Regular monitoring helps you avoid unexpected problems that could impact your users or rankings.
How Often Should You Renew Your SSL Certificate?
It’s essential to track the expiration date of your SSL certificate and renew it before it expires. Many website owners forget this step, leading to “Not Secure” warnings that can scare away visitors. Setting up automated reminders or choosing a certificate provider with auto-renewal can help you avoid lapses in security. Regularly testing your SSL setup ensures your certificate stays active and valid, maintaining a secure connection and protecting user data. Even if you have auto-renewal, it’s smart to verify the certificate manually to confirm everything is configured correctly.
