When was the last time you checked for broken links on your library’s Web site? If you can’t remember, or it’s been more than a month or two, head on over to the W3C Link Checker today and enter your site’s URL. Feel free to play around with the options, most importantly “Hide redirects” but there’s no need on a first run if you’re just wondering how much work you have ahead of you as a result.
I will admit that the browser on today’s iPhones and iPod Touches are impressive. They both do an amazing job displaying Web sites as the designer intended. However, some sites still work much better than others. Recently I’ve been pointed to to a neat little bit of HTML that can improve how your site is displayed on these platforms. Just add this line to the head of your document:
<meta name="viewport" content="width=320">
There are other attributes available including initial-scale, user-scalable, minimum-scale, and maximum-scale. More details can be found on the iPhoneWebDev Google Group.

A robots.txt file is something you can place on your Web server and most search engine crawlers will pay attention to its instructions. Those instructions are which directories should not be indexed by those crawlers. Well, since mid 2003 when it was first noticed, the robots.txt file for the Bush White House Web site has ranged from 1000 to more than 2400 lines long. That was thousands of directories worth of content in whitehouse.gov which was not findable via such search engines as Google. As of mid-day this past January 20, 2008, it is now just four lines long, only three of which actually prevent crawlers from indexing certain directories. (And for the record, most Web masters will agree that these three lines are perfectly reasonable to block.)
I surf the web all the time on mobile devices wether that be my personal Motorola Q smartphone or the Commission’s iPod Touch. Some sites work well, some don’t. Ever wonder how well yours will do? Just head on over to the W3C mobileOK Checker, enter your site’s URL, and get a report. The report is code-centric so knowledge of XHTML and CSS will help you understand the results.
