I run an ecommerce site selling digital documents. In an effort to promote it, I had my VA create videos for each of the documents and post it to YouTube. There are 100+ videos, each unique, each targeting a niche long tail kw/audience. Each video includes an annotation and backlink pointing to the respective money site product page. How do you recommend I start ranking these videos? How do you recommend I start gaining real views? I have no experience w/ YouTube marketing, so this is new territory for me. My only goal is to get interested users to my videos. Should I just buy YT videos and build low quality backlinks (e.g. run a broad match GSA campaign, SB comment blast); and distribute them across my video pages? Or would that be a waste of effort/money? Thanks.
