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).

A potential hint has been identified.
A text in upper case reduces the reading speed by approx. 10%. The single words of the text are not easily recognised by the eye, and the whole text blurs into a block. A text in upper case is perceived as aggressive, amateurish, childish and unprofessional. Use upper case only for short titles.

Compare also with Schriver, Karen in Dynamics in Document Design, page 274:
"When text is set in all capital letters, reading speed is slowed about 13 to 20 percent. Reading speed is optimal when uppercase and lowercase letters are used. When extra emphasis is needed, bold has been found to be a better cue than uppercase."
The tested website contains little text in upper case.
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.
