Website Usability

Content Size

From an usability point of view it is recommended to avoid creating web pages which are less then 200 words as they are unlikely to provide a large amount of information; users will usually need "to surf" for more detailed explanations.

We recommend an online tool providing information about the size of the page (in bytes), the size of the content and the percentage of the page's weight devoted to text content in order to check this aspect.

Content Readability

In search engine optimization process we all know the importance of the content but have you ever wondered how readable your site is? Readability stands for a measure of how easy it is to read and comprehend a document. Gunning Fog, Flesch Reading Ease and Flesch-Kincaid are reading level algorithms that can help you decide how readable your content is. Let's take a look at each of them:

• Gunning-Fog will indicate you how many years of "schooling" will need for some to understand the content. The lower the number, the more understandable the content will be to your visitors. Results over seventeen are reported as seventeen, where seventeen is considered post-graduate level.


• Flash reading ease is an index number that rates the text on a 100-point scale. The higher the score, the easier it is to understand the document. Authors are encouraged to aim for a score of approximately 60 to 70.


• Flesch-Kincaid grade level is similar with Gunning Fog index and it's a rough measure of how many years of schooling it would take someone to understand the content. Negative results are reported as zero, and numbers over twelve are reported as twelve.

Image Analyzer

If users can not see a picture, they need a way to understand what the images represent. To correct problems with images and image maps that cannot be interpreted by screen readers, you have to add an ALT tag to every image.

The tools we recommend examine all images found on a web page to check for any accessibility issues such as: alt, width, height, longdesc.
