The Sitemaps protocol allows a webmaster to inform search engines about URLs on a website that are available for crawling. A Sitemap is an XML file that lists the URLs for a site. It allows webmasters to include additional information about each URL: when it was last updated, how often it changes, and how important it is in relation to other URLs of the site. This allows search engines to crawl the site more efficiently and to find URLs that may be isolated from the rest of the site's content. The Sitemaps protocol is a URL inclusion protocol and complements robots.txt, a URL exclusion protocol.

A real-time visitor statistic map widget or visitor traffic map widget is a script that could show the visitor records on the maps. It is fun to see that you remain a trace on the site or notice that someone is visiting this site with you at the same time. For the owner, it could greatly gain a sense of achievement by watching this map and promoting their motivation to update. For static web-pages/blogs, there are few but awesome free-services we can use to decorate our pages.
