One major criterion for a page devoted to academic research according to 8 sources is appropriate citations for the information included. Bias is a huge indicator of reliability on the Internet, according to 16 of the 19 sources. There are several ways to determine bias, some of which are listed above, such as analyzing the site's purpose and domain name. These factors alone don't make the information invalid but it does mean that a WWW surfer will want to carefully examine the information he or she finds.
