You can tell if your website is credible in six ways.
It may be difficult to find out if a website you are using is credible, but you can look for a few things here:
The author–information about the Web with an author listed here is an indication of a credible website. The author’s willingness to support the presented information (and in some cases his contact information) is a good indication of the trustworthiness of the information.
Date–Any information on research, including information on the Internet, is important. By adding a date, the website enables readers to decide whether this information is sufficiently recent.
Sources–The source of the information presented should be mentioned by credible websites like books and scholarly articles.
Domain–Domain can be purchased and used by any person, for example.com,.org, and.net. The.edu domain is, however, reserved to colleges and universities, while.gov refers to a government website. These two are usually credible information sources (although at times a university assigns its students a.edu address for their own use, whereby they use caution when quoting). Please be careful with the.org domain since.org is generally used by non-profit organizations with a persuasion rather than education agenda.
Site design–it can be highly subjective but a well-designed site can indicate more trustworthy information. Good design helps to make information easier to access.
Writing style–poor orthography and grammar indicate that the site is not credible. To make the presented information easy to understand, credible sites closely monitor the writing style.
Naturally, some reliable websites may not contain all these qualities. If you are unsure whether the site you use is trustworthy, check the information you find with another source you know to be trustworthy, such as an encyclopedia or a book about the subject. The type of websites you use for research may also depend on the subject you study. In some cases, information from the website of a company or non-profit organization, for instance when writing a branch or company overview, may be useful.
