Links to pages:keywords:urls

[Eden]

Hello all
My website pages have urls which dont contain my keywords and apears norelevant words and with numbers:
For example:
http://edengalaxy.com/content/blogcategory/13/28/
2 Qs:
1) how important it is for seo
2) how to sort them out with key words?
My site has been designed in joomla, is this something to do in joomla, and if yes where and how? Or should it be done thru my Cpanel? And how?
Many thanks

There are two possible reasons:

    Improve internal linking structure of your site.
    Include affiliate links with no hassle.
It just so happens that replacing one thing with another is quite easy in PHP.
