There is no central authority to check the quality or accuracy of information found on the World Wide Web. Some sites are created by experts; for example, the LibGuide website has been created by professional librarians; but the vast majority are created by non-experts. It is therefore up to you to evaluate a site before you use it as an information source. Ask the following questions about a site and even when all seems to check out.
Check the authority and accuracy of the site to determine the credibility and reliability of the information.
The URL (web address) provide clues to the authorship and authority of the site. For example:
Look carefully at the content of the site to check if the information is mostly subjective (biased or opinionated); objective (factual) or both.
Check the currency of the site and whether it is updated on a regular basis.
HOW helpful is the overall design of the site?
How well has the site been designed and how easy is it to use?
