I just answered this similar question in the internet marketing room...

One quick way...

Make sure headline has main keyword going at. In tags, keyword want, description include keyword want, not "spammy" but natural and in description say to learn more about xxxx kewyord check out our article at aaaaa.com and other article at xxxxx.com and include your domain.

Then on those articles created with those keywords, put link to youtube videos at bottom.

(make sure to ping video and articles right away, only after everything done)

There's tons of paid and free ways, but if do this one right, quick way to jump onto 1st page of google and generate not only traffic, but if providing value, also sales.
