Evaluating Online Health Information
Tips for patients and families
Many Canadians go online to search for medical and health-related information. The internet is the first source of information for many people, before even speaking to a doctor or other healthcare provider.
Online health information can have many positive impacts on our health knowledge, behaviours, and well-being. Unfortunately, the quality and accuracy of online health information is not consistent, including social media where information quality can be very low.
Being able to evaluate online health information is an important skill.
How do I evaluate online health information?
Use the steps below to evaluate the health information you find online.
Look to see when the website was created or last updated. Health information should be up to date to make sure it's relevant and accurate. Even if the information has not changed, it should be regularly reviewed.
Identify the author to determine if they have the necessary background, experience, or training to accurately discuss the topic. See How to Determine an Author's Credibility for more information.
Health information should be based on facts rather than opinion, rumours, or personal stories. Authors and websites should clearly list their sources, so that you can check the information for yourself.
Read a website's "About Us" page to understand the website's purpose and who runs it. Are they credible and unbiased? Be cautious of websites selling a product. Their information may already be biased, as the goal is to make profit rather than present clear facts. Often product claims are too good to be true.
- Be critical of the details
Be skeptical of websites that look outdated, contain broken links, or have spelling and grammar errors. Patient information should be written in plain language, making it easy to follow.
Be careful when sharing your personal information. Look for a privacy policy to find out how and why your information is being used, stored, or shared.
You should carefully consider the source of the information you find on the internet and discuss that health information with your healthcare provider.

Misinformation and disinformation
Finding information online is faster and easier than ever before. While the information you find online can often be helpful and trustworthy, it's important to keep in mind that false and misleading information online spreads widely and quickly.
As you look online for health information, you need to watch for both misinformation and disinformation.
- Misinformation is inaccurate information. In other words, it means getting the facts wrong.
- Disinformation is false information that is deliberately meant to mislead.
