"Even though machine-level addressing like the URL should never have been exposed in the user interface, it is there and we have found that users actually try to decode the URLs of pages to infer the structure of web sites. Users do this because of the horrifying lack of support for navigation and sense of location in current web browsers. Thus, a URL should contain human-readable directory and file names that reflect the nature of the information space."

A table based layout carries many disadvantages if compared to a purely CSS layout. A CSS layout improves both accessibility and performance.
Further information:
A detailed article by Douglas Bowman can be found onhttp://www.stopdesign.com/articles/throwing_tables/.
Hint for webmasters: Be sure that when embedding third party content, e.g. with iFrame, there are no layout tables included.
The tested website uses table layout.
RSS is a technique that allows users to subscribe to contents of a website such as news, reports, blogs, etc. Atom is a format competing with RSS.
Newly published content is regularly and automatically downloaded on the subscriber's computer or other devices thanks to RSS or Atom. This allows the subscriber to keep up to date.
Functions based on RSS are increasingly integrated in existing applications, like e-mail programmes or web browsers.

DNS assigns an IP address to the names of servers on the internet. It is advisable, to increase the availability of a website, to use several name servers. RFC2182, section 5, suggests to use a minimum of 3 and a maximum of 7 name servers.Source and further information:
http://rfc.net/rfc2182.html, and http://www.rfc-editor.org/.
Acronyms:
DNS: Domain Name System
IP: Internet Protocol
The tested website contains less than three name servers.
To abstract design from the structure and the content, HTML should contain classes. Classes are invisible to web site users, and allow to classify elements, paragraphs, areas, etc.
The website designer can select and re-format classes with a stylesheet. Classes are only necessary if they differentiate elements, paragraphs, areas, etc. A common mistake is for instance the classification of all elements of one type, which does not add any value but makes the HTML and CSS code unnecessarily long, complex and difficult to understand. Such cases are also referred to as "Classitis", see also
http://www.bs-markup.de/blog/archiv/2005/06/30/dr-css/ .
Another typical error is the wrong naming of the classes.
An article detailing these problems can be found on the seven49.net - Papers.
/Web/de/Papers_Links/Bezeichnung_von_IDs_und_Klassen.htm
One or more wrong namings of a class or ID have been found on tested website.
Search engines do not include pages in their indexes which contain "?id=" or "&id=" in their URL or query string. Examples:
http://www.anyaddress.com/index.html?id=727
http://www.anyaddress.com/products.aspx?category=3&id=7
Google does actually index those pages since Autumn 2006, in contrast to their previous practice. Still, those URLs are not advisable since they do not specify how other objects are called, they mean nothing to users and they are not optimised for search engines. An additional tool is available for this test, which allows to highlight any warnings, tips and hints in the source text of the website. You can find this tool here:

"If you decide to use dynamic pages (i.e., the URL contains a "?" character), be aware that not every search engine spider crawls dynamic pages as well as static pages. It helps to keep the parameters short and the number of them few."
Bad examples:
