In the usability article in user centred design, the factors below were identified as one of the most important factors required to create a user centred website that is usable. The 6 primary factors were identified as:Important Factors:
·    Sites primary objective
·    Who is the target audience and their web user skills
·    Potential tasks and goals of the user
·    How would the users expect the site to work
·    How easy will your site be for users

At the point a sixth but less well know factor is the speed at which users access your website. Because of the wide spread availability of broadband, we too for granted that there are significant numbers of users who are still using dial up or have very basic broadband that could not support the demanding graphics web designers tends to use in modern web designs.

Web designer are used to testing completed design projects in various browsers, perhaps they may also was to compare broadband to see how their website downloads using broadband speed test this is not a regular occurrence among web designers so if you are unsure of which broadband provider can give you competitively priced access then you may want to compare prices before you sign up with one.
