Every year, Google I/O provides a glimpse into where the Android and Google Play ecosystems are heading next.

For mobile marketers, the announcements matter far beyond development. Changes to discovery, engagement and measurement can influence how consumers find apps, how developers monetise them and how advertisers connect with audiences once they're inside.

Google I/O 2026 offered plenty to consider. Here are the updates we believe matter most for app and game advertising.‍

‍

App discovery is moving beyond the app store

One of the most significant changes is where app discovery can now happen.

Google announced plans to surface apps and games directly within the Gemini app on Android and web. Google Play is also introducing Ask Play, which uses conversational search to help people find apps and games based on what they actually want to do.

For marketers, this could change how users move from intent to installation.

Traditional app store optimisation will remain important, but discovery is becoming less dependent on users entering a specific keyword into a search box. Apps increasingly need to be understandable and relevant within AI-powered recommendation environments too.

That puts greater emphasis on clear positioning, strong creative and understanding what motivates different audiences.‍

Gaming is becoming an even more connected experience

Google is also expanding the experience around mobile games themselves.

Play Games Sidekick provides an in-game overlay where players can access AI-generated tips, rewards, achievements and social features without leaving the game. Google says the feature has already appeared in more than 100 titles, with wider expansion planned.

For advertisers, the broader trend is particularly interesting.

Mobile games are increasingly becoming persistent entertainment environments rather than isolated play sessions. Players are interacting with communities, rewards and additional content while remaining immersed in the experience.

Advertising formats need to evolve in the same direction. Rather than pulling players away from what they're doing, the opportunity is to create advertising that works within those experiences and respects the player's attention.

‍Marketers are getting a clearer picture of what drives growth

Google Play is also introducing more detailed performance insights.

A new reach metric is designed to show developers their overall visibility across Google Play, while expanded traffic source reporting connects acquisition with downstream metrics such as engagement, retention and monetisation. Google is also adding subscriber tenure, churn insights and AI-powered recommendations to help teams understand why performance changes.

This reflects a wider change across mobile advertising.

Impressions and installs only tell part of the story. Advertisers increasingly want to understand what happens afterwards.

Did the audience engage? Did they stay? Did they generate value?

As mobile marketing becomes more accountable, platforms that connect media delivery with meaningful outcomes will become increasingly important.‍

AI is making localisation easier to scale

Reaching a global mobile audience has traditionally required significant localisation work.

Google is using Gemini to simplify that process within Play Console. Developers can upload structured content and use AI to pre-populate store listings across languages for review. Google is also introducing AI-translated subscription benefits.

The implication extends beyond app listings.

Consumers expect brands to communicate in ways that feel relevant to their market, language and context. AI is making it increasingly possible to create and adapt content at a scale that previously required significant resources.

We're seeing the same opportunity within advertising. Audiomob's AI Generated Ads can help advertisers create localised audio creative across multiple languages, making it easier to adapt campaigns for audiences across markets.‍

AI is moving from assistance to action

Perhaps the biggest theme of Google I/O 2026 was the shift from AI that helps users complete tasks to AI that can take action.

Google introduced Gemini 3.5 Flash alongside broader updates to its agentic development tools. Google AI Studio also gained native Android support, allowing developers to build Android apps from a prompt and publish directly to Google Play’s Internal Test Track.

For marketers, the significance is less about how applications are coded and more about the speed of experimentation it enables.

Faster development can mean faster product iteration, more opportunities to test new experiences and shorter cycles between identifying consumer behaviour and responding to it.

Advertising is heading in a similar direction, with AI increasingly supporting creative generation, personalisation and optimisation at scale.‍

What this means for mobile advertising

Taken together, the announcements point towards a more intelligent mobile ecosystem.

Discovery is becoming conversational. Gaming is becoming more connected. Measurement is becoming richer. AI is making localisation and development faster.

But there is another theme connecting these updates.

The user experience remains central.

Whether people are discovering an app through Gemini or accessing assistance without leaving a game, technology is increasingly being designed around reducing friction.

For mobile advertising, the same principle should apply.

At Audiomob, we've always believed advertising works best when it complements the experience rather than interrupting it. As Google continues to reshape how people discover and interact with mobile apps and games, the opportunity for advertisers is to create experiences that are just as relevant, intelligent and user focused.
