Are there any good methods / tools / templates for evaluating the consistency of multiple websites from one product family in terms of UI components, patterns, button placements, labelling, date formats, UK vs US spelling and its consistent use across products, etc, etc. I'm wondering if there any smart way of conducting this?

Essentially what you want to do is called a 'heuristic evaluation' or 'expert review' - reviewing the sites with a number of different mindsets, or 'hats'.

It's for you to decide in any given site comparison study what it is that is important to you, your business, your client, etc - i.e. which hats you want to wear.

David Travis at UserFocus has an amazingly useful list of 247 guidelines you could use to evaluate a website. These are broken down into:

  1. Home page usability
  2. Task orientation
  3. Navigation and IA
  4. Forms and data entry
  5. Trust and credibility
  6. Writing and content quality
  7. Page layout and visual design
  8. Search usability
  9. Help, feedback and error tolerance

He even provides an excel workbook with all the guidelines, boxes to enter the conformance status, with a result page. You can ignore some guidelines if not relevant.

The result page summarises with a table and a radar chart identifying which categories the site does well, or poorly in.

It's probably not beyond the wit of man to extend this framework to further include criteria that you may be interested in.

Note that this does not provide an absolute guideline compliance statistic. Each question has a context, and each person reviewing may have different ideas of what compliance looks like. However, if the same person does the site comparison then you can compare the relative results of each category of each site. You might get different people to carry out the same expert reviews and compare notes, but don't expect to be able to get good results when comparing your results of one site with someone else's results from another site!

  • Thanks for your reply. Yes, the heuristic evaluation is exactly what I am going to be conducting however, the issue is that I have 5 websites from the same family and I need to evaluate all of them in terms of all 10 heuristic plus consistency of the things I mentioned in my question. I imagine jumping between 5 websites to see whether they all use the same components, patterns, spelling, date formats etc is going to be a nightmare. My task is to work out a template that my team can use for the expert review so that it goes quickly.
