Using Online Link Checking Services

A number of web sites provide online link checking services. They work by reading your web page after you provide the URL, and checking each of the links they find on your page. One such tool is Link Valet from the Web Design Group (http://valet.htmlhelp.com/link/). Figure 18-11 shows a portion of a typical report page.

As you can see, the report lists each link on the submitted page, along with a status indicating the link's health: status 200 is OK, status 302 is also OK, and status 404 means that the page you linked is reported as not found. Link Valet highlights these in red as an indicator for you to do something about it: either to correct the inaccurate link or generate the page it's attempting to link to.

Another similar service is Link Checker from SiteOwner.com (http://siteowner.bcentral.com/ system/linkcheck.asp). This service reports only links with errors. You don't need to wade through screens full of good links to find the broken ones.

The problem with services like these is that you need to submit every single page on your site to check for bad links. As you start to accumulate more and more posts on your site, this quickly becomes an unworkable solution. Recognizing this, most of the online services offer a more sophisticated service, whereby their software automatically loads the pages on your own site (by following links), and checks the links on each of those pages. Although this is a much better way of doing things, even automated checking of the links on every page of a large site can take a considerable time—as much as a few hours. These services generally e-mail you the results or a link to the results in a private area on their server. Not surprisingly, all the services I have seen charge a fee for this more sophisticated checking. They often offer other services, too, like checking your HTML for validity, checking your site for accessibility, and so on. Shop around to find the deal that suits you best.
