evaluating websites

a.a.b.c.

Authority

Accuracy

Bias

Currency

authority / credibility

Who is the author? What are their credentials? Search the source or homepage of a site for information on the author. Search a relevant database to see whether they have published anything in their field. Try Google. Can you find any contact information?
What organization is responsible for the work/site? What is its background and mission? Look for an “About Us” or FAQ link for more information. If they are not a well established organization of which you are aware, look them up elsewhere.
Look at the URL. Is the site commercial (.com), non-profit (.org), educational (.edu), governmental (.gov), or a personal page (look for a tilde (~) in the URL) hosted by a larger entity that is not directly responsible for the content?

accuracy / reliability

Does the work/site look professional? Well organized and formatted? Easy to navigate? Table of contents or search box? Link to the home page? No busy animated graphics?
Are there any errors – spelling, typographical or broken links?
Can you verify the information? Are sources clearly cited? Are they quality sources?
Is research methodology clearly explained? Statistical data organized and labeled?

bias / objectivity

Is the information provided intended to influence your thinking?
Is the author’s purpose or point of view clearly stated? Can you detect any bias?
Does the host organization have an agenda (commercial, political or philosophical)?
Is any advertising distinct from informational content?
Biased information is not necessarily without value. Just be sure to understand the bias.

currency / timeliness

Does the work you want to use provide a date created or updated?
Information posted to the web can sit there indefinitely. Information that was once accurate may no longer be accurate after years have passed.
Is currency of information important for your topic?
Does the work contain broken links or cite out-of-date references?
