Localisation into target languages and cultures has become a need of international corporations that wish to expand. Localisation involves several translation strategies, including transcreation. However, this strategy implies transformation and creativity, which raises questions about the coherence of transcreated messages. The paper applies the functionalist theory and reports on 15 international corporate websites that were localised into Arabic. The slogan is the main focus of the analysis; slogans have an appellative element that needs creativity to be applied if they are to be conveyed correctly. Having selected the transcreated slogans based on predetermined criteria, this study assesses the similarities and differences between the Arabic and English slogans in terms of the overall message and coherence with the description of the product. It narrows down the corpus to focus on that specific quality issue, since coherence can affect meaning negatively if it is done incorrectly, for example, when context is not taken into account. The results show the extent to which the transcreation is coherent, pinpoint the potential accuracy gaps resulting from transcreation and determine how this strategy meets advertising standards
