How do Search Engines Work?

• Don’t really search the World Wide Web directly.But searches a database of the full text of web pages selected from the billions of web pages out there servers.

• Always searches a copy of the real web page.• When you click on links provided in a search

engine's search results, you retrieve from the server the current version of the page.

Site design not suitable Pages not sufficiently tailored for keyword

phrases Not attracting relevant links from other sites
