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.
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'.

The majority of the pages are valid, but not all.
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.

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.
