Frames break numerous conventions that web users had grown used to, e.g. the possibility to save a specific website as a favourite or to mail the direct URL to a friend. In addition, when viewed with older browsers, frames disable the 'Back' button and make it impossible to print out the webpage. Frames are to be avoided as far as possible, even though later generation browsers can handle them better.

The tested website contains so called embedded frames or "iframe" (=inline frame = frame in line with the flow of the text; these are discourage too). Further information: http://de.selfhtml.org/html/frames/eingebettete.htm.
Each page of a website should have its own page title, which reflects the content of the page itself. This carries many advantages, e.g. page titles are used for bookmarking and are read by search engines. Unique page titles therefore lead to search engine optimisation.

Some pages sharing the same titles were found.
HTML is a mark-up language used to create websites, and is independent of platforms.
"HTML is not a programming language, since HTML does not allow to, say, control a robot, set a variable or programme a game." (Quelle)
The display of invalid or incorrect documents depends on the software reading them (browser, roboter, screenreader, etc; see above). However, the display will vary greatly depending on the software, and this can lead to errors, often without the knowledge of the website manager, since it is impossible to test the website against all updates of all the software.
Non validated HTML source text can cause high costs, especially if it causes the software to look for an error or if the functionality and therefore the user experience is impacted.
Further information:
The validity of the HTML source text can be checked with a so-called 'validator'.

Not all visually impaired people make use of technical support to navigate on the internet. The feature to increase fonts is an important element to ensure that all information of the website can be read by all users. Even people who are not visually impaired need to increase the font sometimes. At the same time, an increasing number of older people surf the web; they too need a feature to increase the font. To this purpose, it is important to define the font size not in pixel, but in percentage or "em".

Some font size (less than 5%) are fixed and cannot be increased, or a less ideal feature using Javascript is being used.
"Description" is used to summarise the content of a HTML-page as short and incisive as possible. The content of this meta information is not shown to the user in the internet browser, but search engines do use them to a certain extent to evaluate the relevance of a site for the results page.
The description summarises the content in one sentence. The summaries are normally shown on the results page of search engines and contribute a great deal to the choice of web users.

Descriptions are either incomplete or not optimised on the tested website. Verify that the homepage and the sub-pages contain an appropriate description (a short and incisive sentence).

The logical connection between definition and form field is missing if the form fields lack an explicit title.
This means that in the instance of a linear form, it is not apparent which definition belongs to which fiels. This is why the element LABEL was introduced with the attribute for, allowing the explicit definition for form fields.
Using the element LABEL allows Screen-Readerusers in particular to view the definition of the form field directly in the form field itself.

Most, but not all, form fields on the tested website contain correct labels.
A table based layout carries many disadvantages if compared to a purely CSS layout. A CSS layout improves both accessibility and performance.

Hint for webmasters: Be sure that when embedding third party content, e.g. with iFrame, there are no layout tables included.
On the tested website there are many tables, which most probably are also used for the layout.

Using the ideal number of keywords can contribute to the searchability of a website. However, search engines may class it as "keyword spam" if too many keywords are used.
The number of keywords contained in the tested website is not optimal.
