If you're doing family vlogging, don't just take a shot in the dark and come up with some random topic.
Pay close attention to the successful family vloggers that you see on YouTube.
Pay close attention to engagement level because a lot of these YouTube channels figured out one of the best ways to get a lot more views is to buy views.
You're looking for actual human engagement.
Once you figure out the channels that are legit, pay close attention to the topics of their content, and reverse-engineer them.
What kind of topic or theme appears again and again?
What kind of editing style is common among your competitors?
By understanding the "industry standard" or "industry average" among your competitors, you get a head start.
Does this mean that you just blindly copy whatever it is that they are doing?
No!
This is just intended to give you a start, but eventually, you're going to have to come up with your own twists.
This is where paying attention to your organic visitors comes in.
Of course, it's unavoidable: you have to buy social proof.
You have to buy enough views so people would think that your videos are worth viewing.
You need to also do the same with subscribers.
