For some reason NetMechanic sometimes flags links as broken that work just fine when I try them. This seems to be a temporary problem that fixes itself by the time I try. Great content is important.
Striking graphics mean a lot.
You can do these things yourself, a tedious and never-ending project. Or, you can use one of several web services to will do it for you. What NetMechanic does Go to the NetMechanic website, type in your URL, and wait. In a few minutes you'll get an email with a URL to visit to see the report of the results of a series of automated checks for proper HTML, spelling, broken links, and download times. The report itself is an example of excellent information design.
