What's an important consideration when excluding keywords of categories that you deem unsafe for your brand?

Excluding keywords or categories to protect brand safety is a crucial practice. However, a significant drawback is that it can substantially reduce the available inventory where your ads can be shown. While it ensures your brand isn't associated with undesirable content, over-exclusion can severely limit reach and impression volume, potentially hindering campaign performance. The other options are less accurate: Categories do not change so frequently that their effect on reach is unpredictable; they are generally stable. Excluding unsafe categories is intended to prevent expanding reach to unintended sites, not cause it. Finally, while there's an effort involved, the cost of implementing and maintaining exclusions is generally not prohibitive compared to the potential damage of brand safety issues.
