About 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.

There are three stages of Web Resource Rating:

  1. Assessing inclusion of websites
    Websites we include must be:
    • Not directly funded by a company trying to sell you a product or service
    • Relevant to optimal aging
    • Intended for citizens, or include content intended for citizens
    • Free access
  2. Assessing inclusion of Web Resources from included websites
    Web Resources we review must be:
    • Not directly funded by a company trying to sell you a product or service
    • Relevant to optimal aging
    • Intended for citizens
    • Less than 5 years of age

  3. Assessing quality of included Web Resources
    Web Resources are rated for quality with three criteria:
    • Evidence-based: Is this information reliable, based on scientific research?
    • Transparency: Is it clear who developed the resource and how?
    • Usability: Is the information easy to understand and easy to use?

Each Web Resource Rating also provides a summary of the content, including any information that you can act on related to optimal aging.

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

Understanding our star rating system

Each Web Resource is rated using a star system on a scale from 0-5. The more stars, the higher the quality with 5 being the maximum. These ratings are weighted to favour content that is informed by scientific research evidence, followed by transparency in its creation and ease of use. When you search for Web Resource Ratings on a particular topic, the ones with the highest ratings are presented first.

Our raters

Staff working on the McMaster Optimal Aging Portal conduct the assessments of the resources. Two staff members independently rate each resource and come to an agreement on its rating. Any disagreements in ratings are discussed until consensus is reached.
