What is a YouTube intro video?

Your YouTube intro is a short clip that opens each video from the same channel. Think of it as a TV show opening – it gives the viewer orientation, contributes to the channel’s branding, and sets the tone for the video.

So...what's the best time to post on YouTube?

You can’t go wrong by posting every weekday at around 3 pm EST. This way, your video will have time to reach your audience, and it will have time to become searchable. On the weekend, try posting earlier. Because Saturdays and Sundays (especially Sundays) usually provide more views, YouTubers tend to post more on the weekend. It might be smart to post earlier (like 9 am EST) so that your video doesn’t get lost in a sea of content.
