The Open Internet’s Hidden Monetization Opportunity

The next phase of digital advertising growth may not come from creating more inventory, but from making existing fragmented attention more measurable, addressable and valuable.

The problem is not attention. It is monetization.

Digital advertising has long competed for consumer attention, yet a significant opportunity remains beyond the largest platforms. Thousands of independent apps, websites and digital experiences collectively attract substantial engagement, but their commercial value is not always fully recognised.

The disconnect is measurable. According to Praxis Global Alliance’s report, Rise of Integrated Platforms: How Platforms Compound Value, gaming accounts for approximately 11% of daily mobile time but attracts less than 5% of global media spend. This disparity exposes a structural gap between where consumers spend time and where advertising budgets flow.

The implication is significant: the open internet’s next growth opportunity may lie less in generating additional impressions and more in improving the economics of the attention it already captures.

From fragmented inventory to connected intelligence

Fragmentation makes the open internet difficult to monetize consistently. Individual publishers and apps operate across different environments, with varying identity signals, targeting capabilities and measurement frameworks. Advertisers can access audiences but may struggle to understand them consistently or connect exposure with outcomes.

This limits the value attributed to otherwise meaningful engagement. Publishers struggle to demonstrate their full audience value, while advertisers face greater uncertainty about campaign effectiveness.

The solution is not necessarily to consolidate every digital property under one owner. It is to connect fragmented supply through integrated advertising, data and measurement capabilities.

When platforms can identify relevant audiences, interpret behavioural signals and measure outcomes across multiple surfaces, they can make inventory more addressable and valuable. Better performance builds advertiser confidence, encouraging greater investment and unlocking revenue that existing attention could not previously command.

The competitive advantage shifts from owning more inventory to making existing inventory work harder.

First-party data must be activated, not merely accumulated

First-party (1P) intelligence is central to this transition. As privacy changes constrain reliance on third-party identifiers and cross-platform tracking, direct user relationships and proprietary behavioural signals become more valuable.

The Praxis report highlights how data ownership alone does not guarantee better monetization. Its value depends on whether platforms can translate it into improved targeting, more relevant advertising and credible outcome measurement.

The report identifies different approaches to activating intelligence. Some platforms retain data and advertising activity within their own properties. Others extend campaign activation beyond their owned environments while keeping intelligence proprietary. An open-and-owned model goes further by applying proprietary signals across third-party apps and websites.

These approaches differ in execution but share a fundamental principle: competitive advantage comes from how effectively intelligence is deployed, not simply from where data is stored.

The power of a continuous feedback loop

Integrated platforms can turn individual interactions into a compounding advantage. Audience engagement generates behavioural signals; those signals improve targeting and optimization; better targeting strengthens campaign outcomes; and improved outcomes can attract more advertising investment.

Each cycle generates further opportunities to learn and optimize.

On the open internet, this feedback loop can connect attention across properties without requiring every interaction to occur within a single, closed ecosystem. The opportunity is to make dispersed digital environments function more like a measurable network—improving the productivity of each impression rather than relying solely on greater volume.

This is the distinction between inventory aggregation and intelligence-led monetization. Aggregation expands reach; integration can improve the value derived from that reach.

AI accelerates the opportunity, but data remains the foundation

Artificial intelligence can strengthen this model through automated bidding, audience analysis, personalization and campaign optimization. It can also shorten the time required to build integrated advertising capabilities.

Yet AI cannot independently solve fragmentation. Its effectiveness depends on relevant signals, reliable measurement and continuous feedback from campaign outcomes. Privacy-conscious data practices and respect for user consent remain essential to building sustainable capabilities.

For advertisers, the prize is greater confidence in campaign returns. For publishers, it is better recognition of audience value. For platforms, it is the ability to connect fragmented attention with measurable commercial outcomes.

The next frontier is value per impression

The open internet does not necessarily need more places for advertising. It needs stronger mechanisms to identify, understand and monetize the attention already present across those places.

That requires the industry to move beyond inventory-led growth towards integrated intelligence, outcome-based measurement and continuous optimization.

As the Rise of Integrated Platforms report suggests, platforms can build competitive advantage without necessarily enclosing their ecosystems. Those that connect first-party intelligence with broad third-party reach may be positioned to unlock value that remains underrealized today.

The next phase of digital advertising growth will not be determined by how much attention the open internet attracts, but by how effectively it converts that attention into measurable value.
