How should negative keywords be applied in Facebook Ads to prevent ads from showing to irrelevant audiences?

Negative keywords cannot be directly applied within Facebook Ads in the same way as they are in search engine advertising platforms like Google Ads. Facebook's targeting relies on user interests, behaviors, demographics, and custom audiences, rather than keyword-based matching. To prevent ads from showing to irrelevant audiences, you must refine your targeting options by excluding specific interests, demographics, or behaviors that are associated with the irrelevant audience segments. For example, if you're selling high-end luxury watches and want to avoid showing ads to users interested in inexpensive digital watches, you would exclude the interest 'digital watches' from your targeting settings. You can also use audience exclusions to prevent your ads from being shown to users who have already converted or are otherwise not the target of your campaign. The focus is on defining the *rightaudience precisely, rather than excluding keywords.
