Web Resource Ratings

There is a lot of health information or "Web Resources" freely available on the internet. A Web Resource is any item you find online that you can watch, read, listen to, or interact with, such as videos, fact sheets and online quizzes. Many resources are consumer-friendly, but it's often difficult to know which ones have credible information, based on scientific research.

Web Resource Ratings do the homework for you, assessing the quality of health information available online and presenting our assessment using a 5-star rating scale.

Excluded websites

We don't rate every resource we find on the web that relates to optimal aging. In some cases, entire health-related websites are excluded from what to evaluate in detail. In order to be rated, a Web Resource must:

  • be relevant to optimal aging;
  • come from websites that are free to access; and
  • not be directly funded by a company trying to sell you a product or service.

If you cannot find a website or Web Resource that you are looking for, check out our list of excluded websites. If you still can’t find it, let us know; we may have missed it!
