Meta Data is an interesting topic.
Meta tags are used for web pages and are inserted between the head tags which are at the very top of a web page. This meta data helps search engines crawling your site to determine what they are seeing. The more relevant your meta data to your content and advertising, the better your site will rank.
The concept of meta data can be associated with a lot of content on the internet. Most recently, it was discovered that tagging your videos with meta data correctly can help improve its individual ranking with search engines, much like web pages with meta tags.
Effective software for tagging these videos is scarce, but the new startup - VRMeta - has put together a solution that allows its user's to effectively and accurately place meta data within a video.
