A Seo Optimization is an algorithm designed to search information on the World Wide Web. The information may consist of web pages, images, information and other types of files. Some search engines also mine data available in news books, databases, or open directories. A search engine finds information for its database by accepting listings sent in by authors wanting exposure, or by getting the information from their “Web crawlers,” “spiders,” or “robots,” programs that roam the Internet storing links to and information about each page they visit. Web crawler programs are a subset of “software agents,” programs with an unusual degree of autonomy which perform tasks for the user.
According to The WWW Robot Page, these agents normally start with a historical list of links, such as server lists, and lists of the most popular or best sites, and follow the links on these pages to find more links to add to the database. A Web crawler could send back just the title and URL of each page it visits, or just parse some HTML tags, or it could send back the entire text of each page.
When a user enters a keyword into a search engine, the engine examines its index and provides a listing of matching web pages according to its criteria, usually with a short summary containing the document’s title and sometimes parts of the text. Most search engines support the use of the boolean operators AND, OR and NOT to further specify the search query.
Google, king of all search engines, has one of the largest databases of Web pages, including many other types of web documents. Despite the presence of all these formats, Google’s popularity ranking often places worthwhile pages near the top of search results. Our web searching workshop reflects the fact that Google is currently the most used search engine. Optimal positions can be optained by hiving a Internet Marketing company.
