Use the Correct Language
If you know your market, you can reach them effectively by speaking their language. No, not French or Spanish (although that may be applicable), but by using buzzwords they are familiar with. Using the right term for individual parts of a skateboard, knowing the difference between a motherboard and a computer, knowing that light is measured in lumens – being considered an expert in your market is a sure step to gaining subscribers.
Don’t Be Afraid to Experiment
You can advertise in print media, online, through video, through social media, with PPC adverts, and a number of other ways. The important thing is that every time you try something, learn from it. If you get a poor response from one particular style of advertising don’t keep trying it – learn and move on.
You might be surprised at what does actually work.
