Petal Ads (formerly HUAWEI Ads), an industry-leading mobile advertising ecosystem, calls on brand advertisers to embrace customised on-device all-scenario ad solutions to reach out to audiences across borders and help European advertisers enter the Chinese market. During a special masterclass attended by leading global brands at this year’s OMR Festival, Petal Ads presented on-device marketing as the next evolution in international mobile advertising, which has gained significant popularity in China and is now quickly heading towards global markets.
