They locate sites and automatically index the sites in their databases. In addition, web designers submit their sites to the engines. Directories Directories depend on humans for their listings. Designers submit their sites to the directories. The maintainers of the directories visit the sites and decide which ones will be listed.
Some search engines maintain associated directories.
People submit information and URLs to a directory, and the search engine later visits the sites and obtains more information. There are millions of web sites, and most of them have been submitted to search services. This means that when people search for sites that have themes similar to the theme of your site, they will find links to your site, along with links to hundreds, thousands, and perhaps millions of other sites that have similar themes. Unless you find ways to get your site listed close to the top of the search results, people may never visit your site, even though your site is included in the results. This site is hosted by Shire.
