In overseas advertising scenarios, the core factors for improving multilingual website effectiveness are: language localization accuracy ≥70%, cross-channel keyword consistency error ≤20%, and ad creative cultural adaptation index ≥3.5/5. European market data shows that when CTR variance exceeds 40%, priority should be given to verifying translation quality and contextual expression rather than simply increasing budgets.
Decision-making principles:
• When ad ROI falls below 1.2, keyword library synchronization issues take precedence over creative differences
• In German/French bilingual markets, if CTR variance exceeds 50%, first check verb conjugation and honorific usage compliance
• For European e-commerce, Google Ads and Meta ad search term matching must maintain ≥80% consistency to ensure conversion path continuity

I. Key Evaluation Dimensions for Multilingual Ad Performance
