The Alexa Traffic Rank gives a statement about the popularity of the tested website.
"The traffic rank is based on three months of aggregated historical traffic data from millions of Alexa Toolbar users and is a combined measure of page views and users (reach). As a first step, Alexa computes the reach and number of page views for all sites on the Web on a daily basis.The main Alexa traffic rank is based on the geometric mean of these two quantities averaged over time (so that the rank of a site reflects both the number of users who visit that site as well as the number of pages on the site viewed by those users)."

The traffic ranking of the tested web site is not bad (<= 1'500'000), but can be improved.
"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).

Keywords allow internal and external search crawlers to find content for interested users. Keywords should be chosen from the language and vocabulary of the web user to describe the page content as closely as possible. .
The use of precise and meaningful keywords is still an advantage, even though the importance of the keywords has dramatically decreased for external crawlers. Internal crawlers can still trust your keywords and improve your website search feature.

The tested website does not use any keywords.
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.

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.
Names of links should be short, precise and meaningful. Links such as "more" or the die character sequence ">>" should be avoided, as the user should be specifically told what "more" can be expected.

The tested website contains multiple unspecified links.
