How Search Engines Work
Using search engines such as Google or Yahoo is one of the fastest ways to find information on the Internet. Knowing how search engines work can help you get the most out of your search experience. Use this section to learn what search engines are and how they gather results.
Insights for How Search Engines Work
- Instead of using people to choose sites, search engines use a complex math equation (called an algorithm) to figure out what sites match a search term the best. An algorithm can’t determine if 5.8 million results are more than you need, or if the sites have useful or reliable information—that part is up to you.

Evaluating Web Sites
Search engines can’t tell whether a site has reliable or credible information. Even search results from specialized search engines created especially for young adults still need to be evaluated to make sure that the results are worthwhile. That’s where you come in. Learn how to take a close look at a Web site and find out why evaluating web sites is so important.
Insights for Evaluating Web Sites
- No matter what you search for, one of the top results that you’ll often get is Wikipedia. Wikipedia allows anyone to add or edit information, and doesn’t verify whether that information is accurate or correct. Though Wikipedia is okay for reading about pop culture and nonacademic matters, it can't be considered a reliable source of information for study or school projects. Learn more about Wikipedia and how it works.

Library Web pages are also an excellent source of trustworthy information you can use for school projects and papers. If you're starting an online research project, use the sites below to find the best sources for conducting research, and learn how to cite (give credit to) the sources of your research.

- At-home researchers can get search tips from libraries or librarians by going onto a school or county library Web site from their own computers. These sites often have sections specifically for students, including homework help resources. Libweb lists library Web sites by state.
- Students need to keep track of where they get their information (online or otherwise), and cite (that is, give credit to) the sources used in their reports or papers. The sites in this section help track and create citations for Web (or any other) reference material. We explain how to credit a source for your bibliography in the “How to Cite a Source” section of our Guide to Web Search. When creating citations for a class, check with a teacher to see what citation style is needed.
