Pizza Hut has launched an exciting Instagram campaign to boost its online presence and engage with customers in Hong Kong. The campaign, known as the "City-Wide Battle," has attracted the attention of citizens across the city, with each of the 18 districts taking part in a competition to win a special prize. By liking their district's sweet spot, residents can help their area win and receive a corresponding coupon. In addition, participants must follow Pizza Hut's Instagram tag and tag two friends to increase the brand's exposure. This campaign is designed to increase Pizza Hut's Instagram followers and promote its products and services to a wider audience.
