In the Gulf, the same offer performs differently in English and Arabic, and the audiences rarely overlap as much as teams assume. Running only one well leaves half the market to competitors.
Parallel campaigns do not mean double the work. The strategy, structure and measurement are shared; only the creative and the landing experience fork. Done this way, a bilingual program costs far less than two separate ones and reaches the whole market.
The teams that win the Gulf treat Arabic as a first language of the campaign, not a translation bolted on at the end.
