Before you get anywhere, it is vital to understand your competition. Based on your competitors' pages, you can learn a lot about what customers want and don't want, irrespective of the category. Reviewing complementary products help to bring your attention to the best practices and even promotional opportunities. It is vital that you read the Q&A and reviews on competitor pages. This information can lead you to improve your future product ideas. Also, move quickly. If a competitor is out of stock, this is your chance to strike. You can slightly reduce your prices and run ads to direct traffic onto your page. Use the feedback on their pages to help yourself develop innovative ideas and implement them before your competitors.
