Website Health

"Is the site up" is a narrower question than "is the site healthy." A site can respond with a 200 and still be one expired certificate, one missing security header, or one slow page away from a client complaint or a lost sale.

A website health check bundles several signals — reachability, SSL/HTTPS status, response time, and security headers — into a single view, so you're reviewing one report instead of four separate tools.
