A website health check looks at the things that affect how your site performs and whether the right customers can find it. Speed, security, accessibility, search visibility, and email deliverability — each one shapes how visitors experience your site, and whether they ever land on it in the first place. The tools below are all free, take minutes to run, and surface issues you can actually act on. NDG runs every one of them on every client site as part of regular maintenance.
