Things to consider when evaluating sources of information:
Check out the URL. Is there anything suspicious – Weebly? .com.co?
Skim the home page – Is it useful? Is it the appropriate reading level?
Is the site on point and containing the information you need? Remember to read the information before making a judgement – unless it is clearly off topic.
Is it clear who the author or sponsoring organization is? Does it indicate what their qualifications and background are? Is there an About page and a way to contact the author/sponsor?
Is it free from basic errors (typos, errors, etc.)? Does the information agree with other sources? (Don’t get too bogged down in detail, but the main points should correspond.)
What is the purpose of the site – to educate, entertain, persuade you to a certain way of thinking?
If you need recent information (e.g., you're looking for recent medical inventions) consider if the information is up-to-date. Otherwise, is the site maintained and updated, or has it been created and abandoned? You can check (sometimes) to see when the site was last updated.
