Keyword research simply means finding the exact words people type into search engines when looking for something. In affiliate marketing, the goal is to find words that show interest in buying a product. For example, "best laptop for students" is more useful than just "laptop." Start by thinking about a product, then list simple questions people may ask about it. After that, check if people are searching for those terms. The main idea is to match your content with what people are already searching for. What part of keyword research still feels confusing?
