Google Ads search term reports reveal that broad match keywords typically pull 30-50% off-target traffic, representing the largest single source of controllable waste in most accounts. Categorizing search terms by intent (commercial, informational, navigational) and building negative keyword lists from irrelevant high-volume terms recovers 15-25% of wasted budget. Monthly search term reviews combined with negative keyword maintenance prevent waste accumulation and unlock 20-40% ROAS improvements.
Search terms analysis reveals the actual queries users typed that triggered your Google Ads. By analyzing intent, match type relevance, and performance patterns, you can identify high-value keywords to expand and wasteful terms to block. This granular visibility is critical for optimizing budget allocation, improving Quality Score, and reducing wasted spend across your account.
