How can make the valid google webmaster policies for a site which using most contents from youtube ? According to the policies from google, the site using embedded data from 3rd party will be in violation of the standard content due to its not adding value to the content. I built a site with different categories, collect favorite videos to sort it into these categories. This has been considered a violation of regulations. Are there any solutions to deal with this problem?
You're wrong. 3rd party content duplication refers to text. But you're right, if you're web site is only videos, the content marketing is hard to do. Add text on the video page that relates to the video, do short articles that provide value to the video
