Content testing involves checking the human-interface element of
a Website. You need to search for errors in font type, screen layout,
colors, graphic resolutions, and other features that directly affect the
end-user experience. In addition, you should check the accuracy of
the information on your Website. Providing grammatically correct,
but inaccurate, information harms your company’s credibility as
much as any other GUI bug. Inaccurate information may also create
legal problems for your company.
