YouTube Video SEO part 1

First of all, you need to know that YouTube is a very crowded place. According to YouTube, there are more than 100 hours of video uploaded to the site every minute.

All these video uploads can be described as your competitors. So the obvious question is: How do you get people to watch your videos instead of the millions of others?

The most important signals that YouTube uses is:

Title tag information:
Remember that YouTube and Google can't watch or listen to your video.
That means that they heavily lean on the text surrounding the video to understand your video's topic.
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. Thats why you need to write Super-Long Video Descriptions.

Keywords in description tag:
Before deciding on a keyword for your video, check to see if there are video results on the first page. If so, that's a keyword you should strongly consider because you can potentially get your video ranked in Google and YouTube.

Tags:
Tags help users find your video when they search on YouTube. When users type keywords related to your tags your video will appear in their search results. Use as many relevant tags as possible.

Video length:
A Google researcher from the YouTube team has stated that the ideal video length on YouTube is between 3 minutes and 3 and-a-half minutes on ordinary entertainment videos.

Number of subscribers after watching:
You may have noticed that the most successful YouTube channels constantly remind their viewers to subscribe to their channel in every video they release. Data has proven that subscribers are much more likely to generate more views and watch time for your channel than a casual unsubscribed viewer will, so it’s important to prompt your viewers to subscribe to your channel through a call-to-action (CTA).
