WordPress: Google XML sitemaps for videos
What is an XML sitemap? Well back in the early 2000s, government websites used to have a link on their pages called "Sitemap". This page contained a list of all the pages on that specific website. Even today, some websites have HTML sitemaps. Nowadays sitemaps are created in XML (Extensible Markup Language) instead of HTML (Hypertext Markup Language) and their target audience are the search engines not people.
An XML sitemap is a list of pages on a website that help the search engines like Google, Bing and Yahoo to find pages on your website. It enables the search engines to "crawl" your site allowing them to see the complete structure of your site so they can retrieve or index it more efficiently.
The Google XML sitemap for videos WordPress plugin by author Amit Agarwal, will create an XML sitemap for your website gathering all the embedded YouTube videos and video links in your pages and posts.
