The website must contain a precise and meaningful "title tag", a page title. This is based on the following:
- The title is displayed on the title bar of the browser window.
- The title is used when setting a bookmark (or favourite).
- The file title is shown in the browser in the list of pages previously searched.
- Many search engines offer the title as a hyperlink.
- Search engines use the content of the title for their search.
- Website users often only read the first words and should therefore have enough information about the website.
Equally important is the choice of precise and meaningful titles. The content should be summarised in the title, helping users to find the information needed. According to Nielsen, titles should not be longer than 60 characters.

The tested website contains very short page titles.
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.

A potential hint has been identified.
Alternative text is displayed if an image cannot be downloaded or if the mouse pointer is moved over the image*. The alternative text is on one hand important for visually impaired visitors, using an audio tool to read the content of the website and the alternative text of images.
On the other hand, alternative text can also be recognised by search engines. Alternative text needs to be phrased in a meaningful manner, though it should not be a detailed description of the image.

* Internet Explorer shows alternative text as a tooltip if the mouse pointer is rested on the image. This is not prohibited but it can annoy page authors. It does also indicate that the alt-attribute refers to this tooltip, which is wrong. Should you want to add a descriptive tooltip to your images, make use of the attribute "title".

The tested website contains alternative text for images, though the length of the alternative text is for one image at least outside the range between 8 and 80 characters. Alternative text which has correctly been recorded as empty will not return a negative result.
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.
