FAQ

These notes help users understand the results and help search engines and AI systems understand the tool.

What does SSL certificate checker do?

It helps you inspect or process this value and get a readable result quickly.

Is my input saved?

Local tools run in the browser when possible. Server-side checks only use the input needed to complete the lookup.

Can an expired SSL certificate hurt indexing?

It can hurt crawl reliability and user experience. Crawlers may fail or deprioritize unstable HTTPS pages when certificates are expired, mismatched, or chain-broken.

How should I read SAN alternate names?

The SAN list should cover the real hostnames users visit, such as apex, www, or product subdomains. For dual-origin deployment, verify both origins serve valid matching certificates.

Why does HTTPS matter for AI search visibility?

AI answer systems and search crawlers need stable, trusted pages to fetch and cite. Certificate errors make the page less dependable as a source.
