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. When you research for an academic project, you employ similiar techniques of evaluation. You will determine whether a resource is appropriate for your paper, credible, reliable, and authoritative.
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:
