How do search engines find a website?

Answer 1

They use complex algorithms which take into account:
1) Number of Unique hits per period
2) Number of total hits per period
3) How often the site content is updated
4) The keywords used in the META-Description and META-keywords located in the of an HTML document.

Answer 2

Bots go around websites looking for meta tags that holds the sites key words and description. They hold the data in a huge database. Some search engines also save a copy of the HTML as a cache. When you search the search engine looks at it's database and looks for keywords. This is done very quick. The most relevant is at the top. Search engines find the most relevant by seeing how many links are linked to that page by other results.

Answer 3

Internet search engines are special sites on the Web that are designed to help people find information stored on other sites. There are differences in the ways various search engines work, but they all perform three basic tasks:

* They search the Internet -- or select pieces of the Internet -- based on important words.
* They keep an index of the words they find, and where they find them.
* They allow users to look for words or combinations of words found in that index.

Early search engines held an index of a few hundred thousand pages and documents, and received maybe one or two thousand inquiries each day. Today, a top search engine will index hundreds of millions of pages, and respond to tens of millions of queries per day. In this article, we'll tell you how these major tasks are performed, and how Internet search engines put the pieces together in order to let you find the information you need on the Web.
