Mobile advertising is increasingly moving closer to the device itself as privacy restrictions reshape how advertisers identify and reach consumers. Petal Ads, Huawei’s mobile advertising ecosystem, is promoting on-device, all-scenario advertising as an alternative approach for brands seeking international audiences, with a particular focus on helping European advertisers reach consumers in China.
Huawei’s Petal Ads is positioning on-device advertising as the next stage of mobile media buying, arguing that advertisers can use device-level experiences and first-party data to create more relevant connections with consumers across markets.
The company presented the strategy during a masterclass at the OMR Festival, where it outlined how its mobile ecosystem could help European agencies and brands reach Chinese consumers while also supporting broader international campaigns.
The proposition reflects a significant shift underway in mobile advertising. As third-party identifiers become less reliable and privacy requirements become stricter, advertising platforms are increasingly looking for ways to use first-party signals and their own technology ecosystems to deliver personalization.
Petal Ads’ approach is built around what it calls on-device all-scenario advertising.
Rather than treating a mobile phone simply as a screen for displaying ads, the model aims to use the device and its surrounding services as an interconnected advertising environment. Petal Ads describes the approach as an “Ads-as-a-service” model that can create real-time touchpoints across different consumer scenarios.
Those touchpoints can incorporate multiple interaction modes, including visual experiences, voice, virtual reality and mixed reality.
The idea is to move mobile advertising from a sequence of isolated impressions toward experiences that are more closely connected to what users are doing on their devices.
Why on-device advertising matters
On-device advertising has gained attention because the mobile device sits at the center of an increasingly complex digital ecosystem.
Smartphones contain information about apps, services, usage patterns and consumer interactions. In privacy-conscious advertising environments, platforms that control the device or operating system can potentially use first-party signals without depending on the same third-party identifiers historically used by the open web.
That is the broader strategic advantage Petal Ads is attempting to leverage.
Huawei says more than 1 billion devices are in its ecosystem globally. The company also highlights its position in China, where it says Huawei has a 25% active-user share and a 47.4% share of the foldable-device market.
For advertisers, the appeal is less about raw device numbers than access to an ecosystem with a substantial user base and associated first-party data.
Petal Ads combines that device ecosystem with advertising and data-management capabilities. The platform also works with third-party publishers, allowing advertisers to reach Android users beyond Huawei’s own device environment.
That broader reach is important because an advertising solution restricted entirely to one hardware ecosystem would have limited utility for global media teams.
A gateway into China
The China opportunity is central to Petal Ads’ positioning.
European brands entering China face a market with different consumer behaviors, media platforms, regulatory requirements and advertising dynamics. A global campaign cannot simply be copied into the Chinese market and expected to deliver the same results.
Petal Ads is therefore offering customized campaigns around local events and seasonal opportunities, including occasions such as Black Friday.
The company also said it plans to expand its Global Business Growth Ads Suite, providing premium advertisers with additional media inventory, brand collaboration opportunities and local-market consulting, particularly for China.
This is an important distinction from the standard self-service advertising model.
For brands expanding internationally, media buying is only one part of market entry. Creative localization, audience research, cultural adaptation and local optimization can determine whether a campaign resonates.
Petal Ads is effectively combining media infrastructure with market-entry support.
Competing with ecosystem-based advertising
The strategy places Petal Ads within a larger competitive movement toward first-party advertising ecosystems.
Google operates advertising across Android and its extensive consumer-services ecosystem. Apple has built advertising products around its own device and operating-system environment while emphasizing privacy. Amazon combines advertising with commerce and consumer purchase signals.
Huawei’s model follows a similar ecosystem logic but with a more explicit focus on connecting international brands with Chinese mobile audiences.
The opportunity is significant, but so is the competitive challenge.
Enterprise advertisers increasingly expect cross-platform measurement, transparent attribution, audience portability and integration with their existing DSPs and marketing technology stacks. A device-specific ecosystem must therefore demonstrate incremental reach and performance rather than simply offer another isolated media channel.
Growth creates a larger advertising opportunity
Petal Ads says its advertiser network has grown ninefold since 2020, while its global monthly active user base has surpassed 730 million across 170 countries.
The platform has also partnered with more than 60 certified agencies and brands, according to Huawei.
Those figures point to the company’s attempt to evolve Petal Ads from a device-linked advertising product into a broader international media platform.
For advertisers, that could create another option for reaching consumers in markets where conventional Western advertising platforms may have limited access or different levels of effectiveness.
But the long-term test will be measurement.
Advertisers will want to know how Petal Ads compares with Google, Meta, Amazon and regional platforms on incremental reach, acquisition costs, conversion rates and customer lifetime value.
The enterprise advertising implications
For enterprise media teams, the rise of on-device advertising reinforces the need to diversify beyond a single targeting model.
First-party data, contextual signals, device-level experiences and publisher inventory are likely to coexist rather than replace one another.
The most effective platforms will be those capable of combining these signals while giving advertisers sufficient control over privacy, measurement and campaign optimization.
Petal Ads is betting that the smartphone itself can become a more intelligent advertising environment—and that device ecosystems can provide a bridge between brands and audiences that traditional programmatic targeting increasingly struggles to reach.
Its focus on China makes the proposition particularly relevant for European advertisers looking to expand internationally. But the wider significance extends beyond one market: on-device advertising represents another attempt by the AdTech industry to rebuild relevance and targeting around first-party infrastructure as third-party tracking becomes less dependable.
Market Landscape
The rise of on-device advertising is part of a larger restructuring of mobile AdTech around first-party data, privacy and proprietary ecosystems.
Google, Apple, Amazon and Huawei each control important pieces of the consumer technology stack and can therefore develop advertising products using signals generated within their own environments.
This creates both opportunities and challenges for advertisers.
On the positive side, first-party ecosystems can provide more stable signals and deeper contextual understanding. On the other hand, increasingly fragmented walled gardens can make cross-platform measurement and frequency management more difficult.
For enterprise advertisers, the emerging strategy is likely to involve a mix of ecosystem-specific media, contextual targeting, first-party customer data and independent measurement.
Petal Ads’ China-focused proposition adds another dimension: local market access. As international brands expand into markets with different digital ecosystems, specialized advertising platforms may become increasingly important.
