What I like about it is that when users hover over the image, they can see some basic information about your channel (name of the channel and number of subscribers) and when they click on the image they are redirected to your channel. This is especially useful for videos embedded on other websites. It allows people to be redirected to your channel and subscribe if they enjoyed the video, even if they are not on YouTube to begin with.
When you create a product review video for YouTube marketing, share your personal experience about the product you are selling – which means you must have personally used the product first – and be objective oriented in your video. Be honest and natural in your product review video so that you can win the confidence of the visitors so that they can buy your product.
Finally, consider adding intro and outro music. Intro and outro music, or bookends, can serve as a theme for your content. These are a great choice if you don't need music throughout your entire video. Bookend music can help set the tone for your video, naturally split your content into chapters, and leave your viewers feeling they had a complete experience.
