In order to truly succeed on YouTube, you need to approach it differently than other social platforms. Facebook, Instagram, and Twitter revolve around both creating and sharing great content with the goal of creating awareness, engagement, and conversation. (That’s a simple definition, but for the purpose of this argument, it will work for now). It’s about actually socializing.
There will be two images that you choose. The first will be your account’s picture, which will work similar to Facebook’s profile pictures. The second will be your channel art, which will be displayed at the top of your channel much like Facebook’s cover photo. You need to choose these images wisely, as they’ll be one of the first things that users notice about your brand. In the example below, my account picture is the picture of me, and the flowers are my channel art (please note, this is only an example account).

The first is that viewer attention spans- and loyalty- are a bitch. I’m even lumping in my own impatience online here; as a user, if I click to watch a tutorial, an ad pops up, and I see a similar tutorial in the “You May Also Like This” feed, I’ll give that one a shot instead. I’m not kidding. I’ve done this twice today. You don’t want to do anything that will cause viewers to lose interest in your video, or worse, to click to a competitor’s video instead.
Keywords are the other important thing. You need to make sure you put those keywords in your title so it attracts the right audience. Keywords like social media marketing, search engine optimization, conversion rate optimization, ROI, and blogging are all keywords you’ll find me using. If you know your niche, you’ll know what keywords you need to use.

All channels should absolutely, 100% have a featured video. This video will be placed prominently in the top and near-center of your channel. When users click to it, it will auto-play, catching their attention immediately. This lets you choose how you want to introduce yourself to your viewers. This is particularly important, because the description of your business doesn’t appear on your first page.
What does aperture mean for your video? When a lot of light comes into the camera (with a low f-stop number), you get a brighter image and a shallow depth of field. This is great for when you want your subject to stand out against a background. When less light comes into the camera (with a high f-stop number), you get what's called deep depth of field and are able to maintain focus across a larger portion of your frame.
Tripods range tremendously in price, and the quality of your tripod should depend on the level of camera and lens you have. If you're shooting with your phone, you can get by with a table mount like the Arkon Tripod Mount or a full-size tripod like the Acuvar 50” Aluminum Tripod. For a DSLR, Manfrotto makes a variety of trustworthy tripods starting with the Manfrotto BeFree and increasing in quality and price from there.
