Submit All Content In A Single Sitemap
Sitemaps are a great way to let Google and other search engines know about the content on your website. In order to accommodate video, image, and other non-textual content, specialized sitemaps were introduced. For example, you could submit a sitemap for your html pages, another sitemap for your video content, another one for images, and so on. Seems a bit tedious, right? Well that is no longer necessary thanks to Google now supporting sitemaps that include all of your content types in a single file.
Sitemaps can now be created to reference all of your content, specified by how you want it to be found. Specifically, standard webpages can be identified for a standard web search, videos can be identified for video search and so on. Just be sure to follow the standard sitemap guidelines.
