3) Youtube Description - When typing up your description for all of your Youtube videos you have a maximum of 5,000 words so use them effectively and pepper in your keyword in the description along with other related keywords to your Youtube video. For example read this entire description and you will see the "video optimization" strategy that I use to rank this video on the first page of Youtube.
One of my favorite ways to give content a boost is to run ads on Facebook targeting people with interests that are relevant to the content. It’s fairly low cost since you are offering a free piece of content. By targeting people with relevant interests to your content, you drive the right people to the content and into the top of your funnel. And if your content resonates with them, they’ll share, link, and engage with the content in ways that will help Google see its value.
