Hello,
I uploaded a few videos on Youtube to see what works or not. I uploaded like 12 thumbnails and videos. 5 of them Rank well, the others do not. I wrote my own title and description tags :)
Each thumbnail/video shows up on google. If I delete those I no longer want showing up on Youtube, will they disappear from Google search and images? WIll this hurt my SEO or not?
Another question, why do several videos rank well with a keyword phrase that has nothing to do with that such keyword? Example, you create a video about link building and use propert title tag and description. You, your video does not rank well but a wrestling video does for that keyword link building. Why is this? Makes no sense.
