Search engines can’t make sense of video content on their own, adding 
keywords you want to rank for to the video title and description is 
essential whenever uploading a video to YouTube. Choose keywords that 
best represent the video and terms consumers will search for when 
looking for products or services like yours.
There are many tactics businesses can use to find qualifying keywords to
 help with their video SEO. For example, you can use keyword tools like 
the Google AdWords Keyword Tool
 to help determine the best keywords for each of your videos. However, 
you should also conduct searches for single and long-tail keywords 
within YouTube to help you understand the types of videos that show up 
on YouTube for each term. Seeing how many videos share your potential 
keyword, along with the number of views and related videos on the side 
bar, can help you determine keyword competition and potential viewership
 for your videos. 
Making your video titles, descriptions, and tags SEO-friendly is as important as using qualified keywords.
Titles: The titles for YouTube videos have a
 100-character limit, and you should include your most important keyword
 close to the beginning of your video title. 
 you should consider adding a standard video “trigger” keyword, a word 
that attracts attention in search engine results, to your video. Trigger
 keywords you can use are “review,” “how to,” “about,” or your business 
name keywords.
Descriptions: Video descriptions are a 
critical component of video SEO because they are the main copy 
associated with your video and the largest portion of text that search 
engines can read when indexing videos. YouTube provides up to 5,000 
characters in the description, so use this space wisely and 
strategically craft the text for both SEO and viewers. Also, include the
 same keywords used to optimize your title so search engines and people 
will see a correlation between the two. The description should include a
 summary of the video along with a link to a resource, like your 
website, where viewers can receive more information. 
Creating a playlist for similar types of videos can help improve their 
visibility on YouTube. Not only do video playlists appear within the 
YouTube search results, but other videos in that playlist can also 
appear in the sidebar of the YouTube player as related content when a 
viewer watches a video that’s included in the same playlist. This helps 
boost views of other videos you’ve added, rather than directing viewers 
to other content YouTube deems as similar but that may belong to other 
accounts.
