Misconceptions That Lead us

Astray1. The whole Web is crawled

2. All search engines search the same set of Web pages

3. AND should find more results than OR

4. All search engines work the same

5. Search engines search the actual page at the time of searching

6. “Advanced” features (i.e. Boolean queries), are the best way to search and will get you everything that is relevant to your question

7. Directories and search engines are the same thing

How do search engines

determine ranking? Popularity of the site (indicated by number of links to it)

Link analysis (if more pages point to a site, then those pointers represent “selections” by real experts on a topic)

Collaborative filtering (the choices others with the same query have made)

Exceptions to popularity (new sites have fewer links to them)

Boosting ranking by type of site

Sources of search engine revenues (pay-for-ranking)

Information skewing

Metadata and classification schemes

Context and personalization

Currency is one of the most important

factors in information quality
