Syndicating via YouTube is a very powerful addition to a website for any reason: local business, bloggers, affiliates, and more. As with any platform, changes made to the feed outputs can wreak havoc on syndication strategies. However, there is a good solution for this, and additional information was given specific to FeedBlitz.
The specific question was:
I am having some trouble with the new YouTube channel RSS url working in Feedblitz. They are saying that the RSS feed created using
https://www.youtube.com/feeds/videos.xml?channel_id=CHANNELID is not valid?
For reference on this question see our Knowledge Base post here that explains the updated YouTube RSS URLs: http://support.semanticmastery.com/knowledgebase/updated-youtube-rss-urls/.
