Web users often want to print the content of a page. Neat printing of the content (e.g. without having the borders cut off) can be achieved by implementing a print function and also by including stylesheets which have been optimised for printing.

The tested website does not contain specific technical implementations available on all web pages to allow content of the website to be printed, which usually leads to mistakes and imperfect printing results.

Separating design and structure of the website carries great advantages. The sharper the distinction, the more independent the two areas are. A lack of such a distinction is also called a "spaghetti mark-up" or a "tag-soup" (from the term "HTML tag").
Nowadays it is easy to save colours, type fonts, design images and to a large extent even the layout of the website in CSS files (CSS = Cascading Style Sheet).

Hint for IT technicians: "Code" does not refer to javascript, but to HTML source.
The tested website contains some spaghetti mark-up in CSS format.
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.

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.
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:

The tested website contains "?id=" or "&id=" in the URL (in the part called 'querystring').
