What Are The Types of Metadata Online Video Creators Can Use?
June 15, 2012 in Blogs
There are two types of metadata that are important to video SEO that are important and not mentioned here (I guess they would fall into your category of “Added Metadata”).
The first are (Google) XML video sitemaps. Rather than being used simply for URL discovery, these allow webmasters to declare things like the video thumbnail, title, location, duration, publication date, rating, cost and more.
The second is structured data markup for video, either in RDFa or microdata. The schema.org type VideoObject (designed for microdata but also expressible in RDFa), in particular, allows webmasters to markup more than 60 properties of a video – in a way that the search engines expressly understand.
