I guess it has to do with making sure your site is handicapped accessible, or something. Do you know? Bobby is a software tool designed to determine whether your site meets standards for accessibility. It looks for things like ALT text in your images, context irrelevant links such as "Click Here" , text which is set apart based on color, and many other accessibility issues.
Just type in your URL, and Bobby will tell you if you pass. If you don't pass which you probably won't! Bobby will tell you all the things that are wrong with your site. If you work hard enough, you can make your site entirely Bobby Approved, and you can get a little logo saying so.
Even if you don't want to take the time to make your site fully compliant, using Bobby and studying the results will help you get a much better idea of the problems disabled persons may have trying to access your site.
At the very least, you should try to take care of the most glaring problems. Rather than linking to it here, since it'll probably change locations again, just go to Google and search on "web accessibility evaluation tool". Dear Professor Puzzler I was reading your blog, and in particular I saw your answer to the question about "Bobby. For the most part, the reasons have to do with the fact that an automated tool can't guess at the purpose of an element on the page, and therefore I consider it to be more important to follow the spirit of the law instead of the letter.

For most tools the details of the algorithms used in their rules are not public. Here is the list of issues and triggers. I am ambivalent about this advice. Certainly the logical tab order is not a requirement of form accessibility and thus not really relevant for Section If any link, control or object is not assigned a tabindex, then the tab order becomes very strange. It is easy enough with Bobby's customization to exclude this rule when you do checking for your site.
Each item in the list of errors or questions manual checks is a link that opens the help document for that issue. That help information is very complete and accurate. Figure 5 is a screenshot of the Bobby user interface having evaluated jimthatcher. Figure 5: The Bobby interface. Important differences between the trial version of Bobby WorldWide on the web and the full product include the following.
Figure 5 shows the interface after the rules have been chosen in the preferences Prefs dialog; see the next section. Any URL in the list of analyzed URL's can be activated double click or select and enter to bring up the report for that page. The summary report collects together all the errors and warnings for pages that have been analyzed into one HTML document.
The report first lists the issues, then under each issue, the specific offending pages. The issues link to the help documents and the offending page item opens the actual page. In both the trial on the Web and the full product there are options to use rules, the Web Accessibility A, Double-A, or Triple-A rule sets, and, most importantly, the option to select which rules are to be applied by choosing "Custom" in the Preferences dialog.
Figure 6: Bobby Preferences Dialog. After selecting "Custom" a complete list of rules is available for selection. As you can see in Figure 7, the rules are identified as being part of WCAG or Section , and in the former case, the propriety of the checkpoint. Figure 7: Bobby's Custom Settings Dialog. After a user is familiar with the warnings and user checks, and doesn't want the reports cluttered with the same reminders over and over again, then they can select only those specific rules there are 94 all together that can actually be tested by the tool.
These are the rules labeled as "full support" in early versions of Bobby. This rule selection interface is very compact and efficient with good information relating the rule designation right-hand column with the priority level and the Section reference.
