negative søkeordvsa/b-test

In digital marketing campaigns, "negative søkeord" (negative keywords) are used to exclude irrelevant or low-performing search terms from triggering ads, thereby improving targeting efficiency and reducing wasted spend. A/B testing, on the other hand, systematically compares variations of ads, landing pages, or keyword strategies to identify which performs better. The relationship between negative keywords and A/B testing is practical and iterative: by running A/B tests on different keyword sets—including variations with and without specific negative keywords—marketers can empirically determine which negative keywords most effectively improve campaign performance metrics such as click-through rate (CTR), conversion rate, and cost per acquisition (CPA). This data-driven approach allows marketers to refine their negative keyword lists based on actual user behavior and test outcomes rather than assumptions, optimizing budget allocation and campaign ROI. Thus, negative keywords and A/B testing work together by enabling continuous, evidence-based refinement of keyword targeting strategies within paid search campaigns.
