If you're selling products, consider making a short video of what the product is and how it's used, or give a short tour of your store if you have one. If you're selling a service, you could film some examples of your service or give tips and advice related to your industry. All of these ideas will help to create credibility and make sure your business gets seen.
When making a video, make sure that you keep it short and to the point. It's also important that it's of good quality. Ensure that you film in a well-lit room and that you keep the camera steady. If you're going to speak during the video, make sure the recording is clear and understandable. Then, once you've created your videos, read up on how to embed them on your website.
