Welcome to the Q&A Forum

HolidaySEO With this age group there are places they go and things they look at that older people do not. I have a friend with a daughter who is trying to do similar and is in that target range and I find this all quite interesting. I would look at what other affiliations, likes, etc. they have on the whole. Is there some game they are playing? Is there a set of singers/groups they gravitate toward. Obviously, if so, you want to have something going on there. With Maddi Jane, she has had over 140 million upload views on her YouTube channel so someone likes her. You could go after that in and of itself with blogs about what she does well, etc. That would get her fans reading, and then you start talking up your artist who is similar. Or, have your artist do their rendition of a Maddi Jane cover or if she has done her own songs (all I saw were covers) have your artist do one or two on YouTube - all in a complimentary way. To me this is important. A teenage girl will never speak with you again if you mention you don't think her favorite singer is all that good. Do your artists Tweet? Have them tweet about Maddi jane and other topics around her. OK, through plenty at the wall, hope some helped.

Others are right by the way canonical may be better, but if you insist on robots restriction you should add two schemas to each parameter: disallow:?view=m disallow:?view=m* so that you block the urls that contain the parameter at the end and block the ones that have it in the middle as well.
