  1. The content is up-to-date, authoritative and trustworthy.
  2. The site contains third-party support (e.g. citations, testimonials) to verify the accuracy of information.

  4. The company comprises acknowledged experts (look for credentials).
  5. The site avoids advertisements, especially pop-ups.
  6. Delivery costs are highlighted at the very beginning of checkout.

  8. Each page is clearly branded so that the user knows he is still in the same site.
  9. It is easy to contact someone for assistance and a reply is received quickly.
  10. The content is fresh: it is updated frequently and the site includes recent content.
  11. The site is free of typographic errors and spelling mistakes.
  12. The visual design complements the brand and any offline marketing messages.

How to use these guidelines

Work through each of the items in the list and mark your site as either conforming or not conforming to the guideline.

Remember that all guidelines are context specific. If you feel that a guideline does not apply to your site, it's OK to ignore it.

These guidelines are purposefully expressed as positive statements, so that when you feed the results back to the design team you can identify some strengths of the design before you launch into the problems.
