.@TeamYouTube @YTCreators does having copyright issues affect search rankings? I swear that I have had constant battles with copyrights and saw some of my videos decrease in viewership for series that usually get me over 1k views on them.
Having copyright strike/claim does not affect your search rankings. Having a unique channel name and using proper tags will definitely help your videos/channel discovery. You may also try our course on the Creator Academy: https://goo.gl/DdxMFZ . Hope this helps!
