Web Evaluation Techniques

Before you click to view the page...

• Look at the URL - personal page or site ? ~ or % or users or members

• Domain name appropriate for the content ? edu, com, org, net, gov, ca.us, uk, etc.

• Published by an entity that makes sense ? • News from its source?

www.nytimes.com

• Advice from valid agency? www.nih.gov/www.nlm.nih.gov/www.nimh.nih.gov/

Web Evaluation Techniques Scan the perimeter of the page• Can you tell who wrote it ?

• name of page author• organization, institution, agency you recognize• e-mail contact by itself not enough

• Credentials for the subject matter ?– Look for links to:

“About us” “Philosophy” “Background” “Biography”

• Is it recent or current enough ?• Look for “last updated” date - usually at bottom

• If no links or other clues...• truncate back the URL

Indicators of quality

• Sources documented• links, footnotes, etc.

– As detailed as you expect in print publications ?

• do the links work ?

• Information retyped or forged• why not a link to published version instead ?

• Links to other resources• biased, slanted ?

What Do Others Say ?

• Search the URL in alexa.com

– Who links to the site? Who owns the domain?

– Type or paste the URL into the basic search box

– Traffic for top 100,000 sites

• See what links are in Google’s Similar pages

• Look up the page author in Google

STEP BACK & ASK: Does it all add up ?• Why was the page put on the Web ?

• inform with facts and data? • explain, persuade? • sell, entice?

• share, disclose?• as a parody or satire?

• Is it appropriate for your purpose?

Try evaluating some sites...

1. Search a controversial topic in Google:– "nuclear armageddon"– prions danger– “stem cells” abortion

2. Scan the first two pages of results

3. Visit one or two sites – try to evaluate their quality and reliability
