A search engine is an online service that can aid a user in finding a web page that contains particular content the user is looking for. There are many different search engine services on the web. They are primarily distinguished from each other by the way they gather their information. Searching these engines only requires a small text command, and there are many ways to narrow down your searches. For instance, Boolean operators and phrase searching.

             If a Webmaster does not get his/her web page listed on a search engine automatically, then they might choose to suggest their page to the search engine themselves.

             A Meta tag is a small piece html code used by a website to control what a search engine categorises and stores the site as in their database. It basically tells the search engine what you want your page listed as.

             Search engines are used by millions of people around the world on a daily basis. They are the easiest and most user-friendly way to find content on the Internet. They provide an invaluable service to the Internet user by providing a huge database of websites that the user can quickly search through. Keywords a user enters into the search box are matched to resources in the search engine's database that contain the keywords. These are then sorted by their relevance and presented to the user with the most relevant sites appearing first. The size of the different search engines" databases can vary greatly, as all of the different types of engine don"t gather data the same way.

             Search engines use special indexing software, called robots or spiders, to gather their information. These programs are made to constantly "crawl" the Internet in search of new or updated web pages. They will go through every URL until they have visited every Web site on the Internet.

             When visiting a web site a robot or spider will record all of the text on the main page, then, depending on the search engine, every page within the web site.
