No, there are lots. Look at the bottom of this page for a list of some of the best-known search engines. The search engine will ask for further information about your site. It might even ask for keywords that best describe it. This information is then stored in the search engine's database, which makes your site 'visible' to anyone who searches for it by name, or by description, or using any of the keywords you have supplied.
Some search engines rely on keywords to find pages.
When producing your pages, Webart will code these keywords in the pages we produce for you. Some search engines also ask for your chosen keywords to be included in the submission form when you register the site with them. No, most search engines register you site for free. However, registering your site can be a laborious task, and you may prefer Webart to submit your pages for a small fee. Please check our prices page for details.
