Create a Sitemap – A sitemap is an XML document on your website’s server that basically lists each page on your website. It tells search engines when new pages have been added and how often to check back for changes on specific pages. For example, you might want a search engine to come back and check your homepage daily for new products, news items, and other new content. If your website is built on WordPress, you can install the Google XML Sitemaps plugin and have it automatically create and update your sitemap for you as well as submit it to search engines. You can also use tools such as the XML Sitemaps Generator.
Submit Sitemap to Google Webmaster Tools – The first place you should take your sitemap for a new website is Google Webmaster Tools. If you don’t already have one, simply create a free Google Account, then sign up for Webmaster Tools. Add your new site to Webmaster Tools, then go to Optimization > Sitemaps and add the link to your website’s sitemap to Webmaster Tools to notify Google about it and the pages you have already published. For extra credit, create an account with Bing and submit your sitemap to them via their Webmaster Tools.
