Think about the technology being used – some of your intended audience may have old equipment such as monochrome screens or poor graphical capabilities, some may be using screen readers, screen magnifiers or mouthsticks
Think about colour and visual effects. Is the page clear in greyscale? Do links change to a less visible colour after use? Does anything flash or move and if so is there a capability to switch them off at the start of the page?
Organise materials in a simple and logical order. The order of your information may be obvious to you, but will it make sense if read linearly? Will it make sense to someone with perceptual difficulties?
Present a clear organisational structure. The first page should be no more than an overview, with clear pointers to the remaining material and each subsequent page’s content.
Each page must make sense in its own right. Include links back to the start page and a brief overview of where the viewer is in the schema. Put this information at the end of each page (to avoid irritating screen reader users)
