To help others find your site on the web, you’ll need to start by letting search engines know your site exists. Although search engines routinely trawl the Internet to update their databases with new sites, pages and content, this process isn’t instantaneous; the fact that you have a website doesn’t mean you’ll instantly appear in search engine results, even if you search for it using the address (URL) of your website.
Google is by far the most-used search engine in most countries, but there are many others. Help people find your site by submitting it to as many different search engines as possible.
To submit your website directly to Google's search engine, just click here, and to submit it to Yahoo and Bing (they use a unified service), click here.
