Evaluating Web Sites

Below you will find some information you can use and questions you can ask about web sites that you are viewing.  Evaluating a web site is useful for personal surfing as well research and study.

Remember : Not everything is on the Internet; "anyone" can put up a web page; learn about the invisible/hidden Internet or deep web.

Look at the URL (Universal Resource Locator) aka the web address, analyze it

     Is it a personal page? Characters in the URL to alert that this may be a "personal" web page:

                   ~          %         members        aol       geocities    google   sites     users

     Personal web pages can provide sound information, but they are created by an individual.
     You would be advised to scrutinize these pages and ask a lot of questions about them.

     What kind of organization is behind it?  Look at the TLD (Top Level Domain) in the address:

 Domain  Entity  What will this tell you about the site?
 .aero  air-transport industry  Must verify eligibility for registration.
 .asia  Asia-Pacific region  For companies, organizations, and individuals in the Asia, Australia, and the Pacific.

      Government entities will often have additional domain identifiers such as:

                        .ky - Kentucky  .ca - California  etc.


Why does this website exist - why was it put on the web - what is the purpose? 

  • Inform with facts/data?

  • Why believe them?

  • What is their bias or agenda?

  • Check page sections such as:
     “About us” “Sponsors” “Philosophy” “Biography” “Who am I”

  • No background info?
    Truncate the address (URL) one section at a time.
    Search the responsible authors, corporate body names on the Internet.

What is the quality of the content? 

  • Is responsibility clearly stated?

  • Is it a commercial, govenment, educational, private, etc. site?

  • Are sources documented in footnotes or links to outside works?

  • Are the links maintained? Lot of dead links?

  • Are other points of view stated or referred to?

  • Is this hype / trash / ranting / violent / overtly sexual / etc. 

What do others say about this page?

  • Who recommends it?

  • Who advertisers on it?  How much advertising is there?

  • Paste the URL into a web site like to find information.

  • Google, Yahoo, Bing, etc. the author or company name.

Try a search in subject directories – smaller than search engines, usually chosen by human interaction not necessarily computer robot programs.  Some examples: 

How much information is on the Internet?

  • There are two groups of Web content. One, which we would call the "surface" Web is what everybody knows as the "Web," a group that consists of static, publicly available web pages, and which is a relatively small portion of the entire Web. Another group is called the "deep" Web, and it consists of specialized Web-accessible databases and dynamic web sites, which are not widely known by "average" surfers, even though the information available on the "deep" Web is 400 to 550 times larger than the information on the "surface."--From U of California, Berkeley's How Much Information.

  • It is very difficult to know exactly how big the Internet is. Most sites that monitor this concentrate on use/general content and not specific content. For instance, see Internet World Stats.
