Remember that YouTube and Google can’t watch or listen to your video (yet). That means that they heavily lean on the text surrounding the video to understand your video’s topic. Well, the more YouTube knows about your video, the more confidently it can rank it for your target keyword.
But more importantly, YouTube uses keywords in the description to rank you for super-long tail keywords. Ranking on YouTube is great, but ranking your video on YouTube and Google is even better. Although Google gives YouTube videos an inherent edge in the SERPs, that’s only true for certain keywords. These keywords are called “Video Keywords” because they tend to have video results on Google’s first page.
Online communities like Quora and LinkedIn groups are fantastic places to funnel traffic from. The thing is, most communities don’t take too kindly to someone dropping links to their content all over the place. But they’re usually open to people sharing helpful YouTube videos, like yours! Because the number and quality of your video views are one of the most important YouTube ranking factors, getting views from targeted communities works wonders. Just find a question in the community that your video could help answer. Then provide some value and suggest that people watch your video if they want more information
Because YouTube’s algorithm doesn’t use backlinks, it puts A LOT of weight on user experience signals. If people enjoy watching your video, expect it to crush it in YouTube search. Subscribing and liking are two of the most important user experience signals that YouTube uses. When someone likes your video enough to subscribe after watching it, it sends a strong message to YouTube that you have a killer video on your hands. Likes are much less important, but they still count. You can ramp up both of these user experience signals by asking. At the end of your video, give people a strong call to action that encourages them to subscribe.
