How to do a Link Check
A "link check" will show you the websites that are linking to the website you are evaluating. Knowing the types of websites that are linking to a single website will help you to determine whether or not the website contains information that is reliable.
Link checks are done by using the AltaVista search engine.
Go to AltaVista. In the "Search" bar, type in the word link plus the URL of the website you are checking. Example: link:http://www.sandiegozoo.org Then click the Search button.
Try the example and see how many and what type websites are linking to the San Diego Zoo.
Why Link Checks are important
We all know that not everything that is published on the internet is true. We also know that there are a lot of organizations that have a certain point of view and try to persuade others to join that point of view.
There are also those groups and organizations that have points of view that can be very unpleasant to others. When you encounter a website that makes you feel uncomfortable, doing a link check to find out what is linking into that website will oftentimes tell you what type of website it really is.
1. Go to Google.
2. Type "Martin Luther King, Jr." into the search box.
3. Look on the first page of the search and find the link to "The King Center.
4. Look at the URL. What is the extension for this website? What type of site is it?
5. Go to the "About" page and describe the purpose of this website.
6. Do you think this is a good website for research about Dr. King?
7. Return to your Google search results.
8. On either the first or second page locate a link that says "Martin Luther King, Jr. - A True Historical Examination then click on the link.
9. Can you locate an "About Us" link? If not, do a link check with the name of the host of the website. What do you find?
