Channel trailer:Your trailer should be short and sweet (around 30 to 60 seconds). Focus on showing visitors what your channel is about and what they can expect to see in your videos. Don't forget to encourage them to subscribe. Your trailer won’t be interrupted by ads, which will keep the user focused on why they should watch more videos from your brand.

Search engines look at your description when determining how to rank your profile, so incorporate relevant keywords in your overview. We’ll talk more about how to optimize specific video descriptions below.
