Looks good & works well, based on a couple of sites-- unsure on the doctor image. It's funny but it might prevent some people from taking the site seriously. -

Looks good & works well, based on a couple of sites-- unsure on the doctor image. It's funny but it might prevent some people from taking the site seriously. -- remove "example.com" from search box when gets focus? -- rather than blacklist certain domains, maybe you could cap the number of link checks? With utilities like this I always try a popular site to see how it works, before entering one of my own sites. I was unable to do that, which was a little frustrating at first. -- add a quick description of service on main page? Not sure if "check your website's links" would be obvious to everyone.
