Answer:
There could be many challenges marketers can face when attempting to use differentiated marketing for different cultures and ethnicity. Each and every culture has its own norms, value, ethics, rituals and language which is different from other culture. Markets when going for the differentiated offerings then they must take care of those differences as well. For example, in Saudi Arab, you can't put female pictures on your packaging. Beef burgers can't be sold in India, which was done by McDonald's and they had to face quite strong resistance. Therefore, when marketers go for the differentiated marketing in different cultures, they must be aware of the norms and values of that culture.
