Finding keywords that are not crowded by big Amazon pages can take some careful searching. One way is to focus on very specific topics, like small product categories or unique use cases. For example, instead of "best headphones," try something like "best headphones for night study." Also check forums, question sites, and comment sections because people often ask detailed questions there. These questions are not always covered by big sites. Looking at search results and avoiding keywords filled with large brands can also help. What method seems more practical for finding these gaps?
