No. You can, but it won’t help you generate ROI. So, please, don’t just make one video and then abandon it.
The real question here is, “Do I want to give my ideal customers multiple chances to learn how I can help them?” To maximise your online exposure, you should create several videos that teach others about you, your products, and services. Multiple videos will also help raise brand awareness, improve SEO, and establish you/your brand as a thought leader, among other benefits.
In contrast to television, you can’t really measure anything until it’s too late. Sure, you’re hoping that a large number of people will tune in at the exact moment your ad is running, but you can’t count on it.
