The key difference between web and print design is that web design is dynamic – it will be presented differently on different screens, operating systems and browsers. With regard to this medium there are also many other specific areas that need checking. Here at Feelingpeaky we look to spend time ensuring that we make our web sites look great who ever might be viewing them. To this end we have prepared a check list for our team to use which I thought I would share here. Whilst not completely original I hope you’ll find it a useful resource:

Website Testing Check List

The following is a quality checklist for elements to test on a brochure web site.

  • Title tags – spelling, appropriate and sensible, SEO friendly?
  • Other Meta data required? Or blank? Appropriate and sensible, SEO friendly?

  • All styles, JavaScript in linked in files and not inline.

Layout and Content:
