A thumbnail image is a small rectangular frame containing an
image which appears when a user searches for a video. A
thumbnail gives an idea to the viewer of what they should
expect. Ergo, choose a video thumbnail consciously. If you don’t
decide on a thumbnail on your own, YouTube will do that for
you. This sounds alluring, but don’t fall for it. It will randomly
pick a moment from your video and add it as a thumbnail. In
this case, your video might end up with an awkward thumbnail
which will repel the users instead of making them feel
interested. While adding your own thumbnail, make sure that it
has a resolution of 1280 X 720, less than 2 MB size and a 16:9
aspect ratio
Use a thumbnail image consciously
The search engine algorithm prefers to rank content that is of
good quality and helps users to understand the topic in the best
way possible. A clear title, relevant thumbnail, thoughtful
description helps with this, but adding a video transcript makes
it even better. A video transcript is your video content in text
form. Uploading your video transcript will help you rank better
as they are crawled for SEO purposes. Moreover, if your
audience has difficulty hearing or are not very familiar with your
accent, they can read the transcript and follow the video.
Use video transcripts
