To find keywords with high CPC (cost per click), you can use keyword research tools such as Google Keyword Planner, SEMrush, or Ahrefs. These tools allow you to research keywords and see their estimated CPC, as well as other metrics such as search volume and competition level. Additionally, you can look at keyword-specific niche websites and industries, such as insurance, finance, or legal services, which generally have higher CPCs due to the high commercial intent of users searching for those keywords.
