How to cite a website, is something that students or people that write articles often query about on the internet. The way you cite a website depends on the type of article (or dissertation / thesis) you write.

1. Academic

Referring to a website in an academic work depends upon the reference system that is required from your university.  In the Harvard System, it would look like this:

Authorship or Source, Year. Title of web document or web page. [Medium] Available at: include web site address/URL(Uniform Resource Locator) and additional details such as access or routing from the home page of the source. [Accessed date].

Example (not real): 

International Information Website. 2008. How to improve your scoring in exams (Hitting the headlines article). [Online] (Updated 18 June 2009)
Available at: http://www.internationalinfo158.com/exams.html [Accessed 10 April 2010].

2. In websites or blogs

In a website or blog article, there are two ways of referring to a website.  The one way is to link to the complete url:

example 1: http://www.queryabout.com/index.php?option=com_content&view=article&id=5&Itemid=17

Most blog software or content management systems today automatically knows if it as a website link.  A More subtle way of linking to another website on the internet is by adding a link to any given text:

example 2: click here to take free piano lessons

Most internet editors have a "link" button that you can use to link in this way.

HTML Code 

The html-code for both website referral methods are:

a) Linking to a site straight forward:

<a href="/piano/learn-to-play-the-piano" mce_href="/piano/learn-to-play-the-piano">http://www.queryabout.com/index.php?option=com_content&view=article&id=5&Itemid=17</a>

b) Linking to a site by another word / anchor:

<a href="/piano/learn-to-play-the-piano" mce_href="/piano/learn-to-play-the-piano">here</a>

In Forums 

In forums, one can often insert a url by [url] and [/url] tags.  The code for the above examples are:

a) Linking to a site straight forward:

[url]http://www.queryabout.com/index.php?option=com_content&view=article&id=5&Itemid=17[/url]

b) Linking to a site by another word / anchor:

[url=http://www.queryabout.com/index.php?option=com_content&view=article&id=5&Itemid=17]here[/url]
