Your YouTube description is a fantastic opportunity to ask viewers to continue to engage with your channel or find additional resources that will help them learn more about a topic of interest.

For instance, let's say you create a brief "How to Add Filters to Instagram" YouTube video, but you also have an in-depth "How to Use Instagram for Marketing" blog post. Why not link it in the description? Most likely, anyone watching your Instagram video on YouTube would be equally grateful for the opportunity to learn more through a blog post.

Perhaps you simply want to ask viewers to subscribe, turn on notifications, or share your content with their networks. These are all acceptable CTA's for your description.

You must format your description to ensure you put the most important information first. Peters advises, "The first 200 characters are above the 'more' fold on the description box, so if you want your CTA/link to be seen by most people, keep it within the first 200 characters."
