For the last couple of months I've been working with accessibility Web Content Management (WCM) in MOSS 2007. During that time I have gathered some do's and don'ts for working with accessible WCM solutions.
Every time you request a web page that doesn't exist, the web server provides you with a 404 (the web server response code for an non existing URL) page - an information page telling you that you've got it wrong. While some of your visitors, might be able to get to the information they are looking for either by correcting the URL or finding an alternative way to access the resource, it is a good practice to provide an information page which will help the average visitors to continue the navigation like nothing really happened.
Semantic URL's are one of the things I always wanted to have in Microsoft Office SharePoint Server 2007. Since the first time I have opened an Internet facing site made in SharePoint 2007 I knew it would be great if the Pages part of the URL could be removed as well as the .aspx extension.
XML sitemaps, as defined by Sitemaps.org, are a standard way to inform search engines about the content of your web site. While in many cases your site will be automatically crawled for new content, there may exist pages without any direct link. Using an XML sitemap is a way to let the search engine know about its existence.
I have spent the last days on optimizing performance of the Imtech SharePoint Enhancement Toolkit: a toolkit that I have built in order to achieve standards compliancy, accessibility and slightly better performance of Web Content Management (WCM) solutions built in SharePoint 2007.
