XML sitemap are best an easy method to inform search engines about the website content/pages.
XML sitemap lists URLs for a website along with additional information like: date of update, how frequently usually changes, and importance.
XML sitemap offer the ability for you to give a priority ranking to all your webpages on a scale from 0.0 to 1.0, with 1.0 being the most important and 0.5 being the default neutral rank. For example your index page you would give a ranking of 1.0 to, while your terms of service page you would probably want to assign a 0.1 to. This point value system helps the search engines by giving them and their bots a way to know which pages on your site you value most and therefore which to spider more frequently.

=> New site pages are quickly indexed.
If you don’t have a webmaster account with Google or are too lazy to go around to the various search engines and submit the sitemap URL by hand but still want to get your sitemap indexed faster than by letting the search engines eventually find it on their own, you can simply place the URL to your sitemap directly in your robots.txt file for sitemap auto discovery by the search engine bots the next time they visit your site.
