The inbound methodology is the marketing and sales approach focused on attracting customers through content and interactions that are relevant and helpful. Each video you create should acknowledge your audience's challenges and provide a solution. Looking at the big picture, this content guides consumers through the journey of becoming aware of, evaluating, and purchasing your product or service.
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.
You can choose a feature video from any of your uploads, or create a video specifically for this purpose. I recommend doing the latter; it allows you to create a short video (no more than 90 seconds, preferably) to welcome viewers to your channel and explain what you can offer them. This brief clip may not seem like a big deal, but in my experience it can go a long way in getting people to subscribe.
