The Internet contains numerous search engines, some of which offer what is known as "paid inclusion." This means that you pay the specific search engine an annual fee for your web page to be included in their index.
Of course, every search engine already has an automated program commonly called a "spider" that indexes all the web pages it locates online, and it does this for free. So whether you pay or not, your web page will eventually be indexed by all Internet search engines, as long as the spider can follow a link to your page. The major issue is, then, how quickly your page is indexed.
