Whether you're on a blog, reading comments in a Reddit thread, browsing images on Pinterest, you're evaluating the information. Based on your interests or information needs at the time, you evaluate the piece by who posted/pinned (their knowledge or skills), the quality, the currency, its genuineness, and so on.

The following list will assist you in developing a strategy for critically evaluating sources:

As researchers we have to work hard to determine the authority, credibility, and quality of the content.

Develop a habit of evaluating each website you visit. The criteria list above can be also be applied to the web, but here's a short list of questions for you:
