Hey I try to rank my videos higher, using (for now) standard SEO - tags, description, titles etc. What I see is that the new videos have much more views in real time than the older ones; I have music channel (hip hop instrumentals) and I wonder if I should try to rank my instrumentals from 2011,2012,2013 by changing titles, tags etc (I of course do that, but I don't see big views boost). The difference between old videos and new ones is that the new ones are in HD (actually its just a picture and the music, but still its HD) when older ones are in 240 and 360p. So what would You recommend to me? Try to re-upload old instrumentals and do it in HD and then try to do SEO or is it possible to rank older videos just by SEO, even if they are in low resolutions, for example 360p? Competitors videos are mostly in HD. Is that factor really that important? My videos from 2011 were very poorly tagged and titled (then I didnt know about that, I only uploaded it with title rap beat etc.) but some of them has over 40k views. So I don't know whats better to do now. Thank You very much for Your help! Seagate PS. Sorry if its the wrong thread. Im new here and I really apologize if I posted in wrong place.
