While some advertising can transfer across borders, cultural and market differences make transference difficult. According to an analysis of over 6,000 ads, on average only 52% of ads transferred successfully to other markets. Africa in particular shows low transference at 43% due to strong cultural variations within the continent. Key factors that impact an ad's ability to travel include the category's development stage, the brand's meaning and recognition in different markets, differences in media environments and advertising norms, and cultural response to messaging. A checklist is suggested to evaluate these factors when considering transferring ads between markets.
