"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."

The tested website does not comply with this requirement.
The titles need to be ordered in a sytematic and logical way, i.e. there can be no jump going from h1 toi h6. In addition, the first title must be h1.

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.

A potential warning has been identified.
Missing height and width size of images is a typical error in HTML, which impacts the performance of the website. A precise definition of height and width allows a quicker download of the website, as the browser recognises the space needed for the image and can leave it empty.

At least one image with missing information about height and width was found.
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.

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."
