Sitemaps are a way to tell Google, Bing and other search engines about web pages, images and video content on your site that they may otherwise not discover.
The Video Sitemap plugin will generate an XML Sitemap for your WordPress blog using all YouTube videos that you may have embedded in your blog posts.
Your Video Sitemap will includes web pages which embed videos from YouTube or which links to videos on YouTube. If a YouTube video that you have in your blog has been removed from YouTube, the record in the Sitemap file will be ignored by Googlebot.
