While Google Scholar may not be the only place you go for your research needs, it can be a great resource when browsing your topic or looking for a specific article!
Looking at website domains can help you to decide if the information on a website is credible. Domains provide insight into website affiliation. Websites ending with .gov for government websites and .edu for educational websites are often more trustworthy than a commercial (.com) website. Websites associated with an organization (.org) can also contain useful information but always remember to confirm any commercial bias the organization may have.
There are many different ways to evaluate a website. Check out the CRAAP method below or check out the Research Tips page for other methods.
