3in1 or standalone?

Hello,

Let's say I have gaming niche which I want to promote in 3 keywords. Example: download, crack, keygen. Would it be better to make separated videos for each keyword? Finally, would it let me promote and bring them up in SEO easier? I find it hard with "new YouTube" to get to the top 10 results with video I would like to promote in more than 1 or 2 keywords.

With regards,
Cromiell

You have to make a good title and some tag, you can have the best place in the 3 keyword

But it doesn't matter anymore. I am really okay in making SEO if we talk about title/tags and description. It's the "new" YouTube making a lot of problems. While I was easly getting to the top 6 months ago, now I'm not even in top 7. Mostly 2nd half of 1st page.
