2. Use Amazon's keyword tools: Amazon provides some keyword tools, such as keyword recommendations, search term reports and competitor analysis, which can help sellers find more relevant keywords to expand the coverage of advertising.

3. Exclude invalid keywords: In order to avoid wasting advertising budgets and reducing advertising quality scores, sellers need to regularly monitor and analyze their advertising data and exclude invalid keywords. For example, keywords that are irrelevant to their products or have negative connotations, competitor brand names, etc.

4. Regularly update and optimize advertising keywords: Sellers need to regularly monitor and analyze their advertising data, and adjust and optimize their advertising keywords according to market changes and user needs.
