How it Works

  1. Have users of a website answer the 8 SUPR-Q items: Do this either using a pop-up on a website, a survey or after a usability test. Note: The older version of the SUPR-Q used 13 items.
  2. Paste the responses into the calculator: The calculator automatically generates percentile ranks for a global score and each of the four sub-scales (Usability, Credibility, Loyalty and Trust).
  3. Compare your results to other websites: For the full license, you can see how your score compares a list of 150+ websites across twenty industries, government and academic institutions.
  4. Unlimited Users and Tests: The license permits you to administer the SUPR-Q for an unlimited number of tests, users and websites. There are no expensive scoring costs or hidden fees per use.

SUPR-Q Background

The SUPR-Q (Standardized Universal Percentile Rank) measures the essential aspects of a website in just 8 multiple choice questions.

It was developed through a process called psychometric qualification, in which the best 8 items from a pool of 75 candidate items were identified. A peer-reviewed journal article discusses the validation process in detail. The items were winnowed down by only retaining those which generated high internal reliability, loaded highest across common factors, had the highest item-total correlation and could discriminate best between websites.

The database contains responses from more than 10,000 participants and 250 websites. The websites are updated on an ongoing basis (about once per quarter).

Usability: If users can't accomplish what they want to do, find the product they're looking for, or complete their purchase, it's as if like the information or product doesn't exist. A usable experience means a profitable experience.

Credibility (Trust, Value & Comfort): Does the website sell products and collect credit card information? Are you gathering email addresses to build a subscriber base? If users don't trust your website, which for many companies is synonymous with their company and brand, they won't give up their information and website growth is impeded.

Loyalty: Are users talking about your website favorably or are they telling their friends to avoid it like the plague? Will they return to the website and purchase more things or at least see what you have to say? These two items touch upon repeat usage from existing customers and net-new usage from new customers.

Appearance: Is your website looking like it's circa 1998, or is the appearance hindering the experience? Users form impressions of your website based on the appearance in just a few seconds.
