On-demand indexing -- rather than manually entering URLs or keeping a Sitemap up to date -- can save time. So Webmaster Tools has verified that a site owner can now have a page that links to their site's latest content index more quickly by providing Google with the URL. Google will periodically visit the URL to discover new links to content and add it to the index.
