Frankly speaking, advertising is an effective way to drive sales. However, you need to understand one truth about advertising. It is not foolproof. I will share my own story, my first few attempts on advertising through Facebook and Google went wrong, I made no sales. However, I also learned so many things about digital advertising. On my subsequent attempts with ad campaigns, I was managed to generate sales. You can generate sales through ads only when you start your campaign properly. You need to be careful about audience target, advertising platform, and advertising budget. Last but not least, your ad needs to be visually impressive.
