Importance of YouTube Video ID | YouTube SEO [2021]

SEO of a TH-cam video is very important to expand your reach and spread your content to the relevant people. You can use a video ID to search on google that where your video is shared.
If your video title and description are good and you do not intend to change them then you should perform SEO of your videos but if you prefer to change the tile and/or description then first change them and then start the SEO process because if you shared your videos on different platforms before the changes then there is a chance that Google might show the old tile and/or description as I explained in the video.
