Google's Ad Empire Is Cracking From the Inside Out

Alphabet just posted another record ad quarter. Google’s Network business — the part that actually funds the open web — declined year over year. Again. Those two facts sitting in the same earnings report tell you almost everything you need to know about where the power is moving.

Record Revenue, Shrinking Reach: The Alphabet Paradox

AdExchanger’s analysis of Alphabet’s Q2 2026 results reveals a company that is winning at advertising while quietly retreating from the open-web ecosystem that made it dominant. Search and YouTube continue to compound. Network — the business line that channels spend across third-party publishers through AdSense, Ad Manager, and the programmatic stack — keeps contracting. The implication for brands running awareness and upper-funnel campaigns through Google’s network inventory is uncomfortable: the pipes are getting narrower, and Google is not visibly investing in widening them.

Stack that against a 4.1 billion euro antitrust ruling that Google lost on appeal in early July, and the picture sharpens. The company is under regulatory pressure on one side and structurally de-emphasising the open web on the other. For Southeast Asian markets where brand budgets still flow heavily through programmatic display — particularly on Grab’s and Lazada’s ad networks, which rely on similar infrastructure — this is not a distant problem. It is a procurement and planning problem for Q3 and Q4 budgets right now.

The Attribution API Debate Is Really About Who Controls the Data Layer

Meanwhile, at the W3C, a quieter but more consequential fight is playing out. Digiday reports that Google’s proposed Attribution Reporting API — the mechanism intended to replace third-party cookie-based attribution in a post-cookie Chrome environment — is drawing serious pushback from independent ad tech players who see it as a structural advantage baked into the browser itself.

Critics are calling it Privacy Sandbox 2.0, and the label is not entirely unfair. The concern is architectural: when attribution logic lives inside the browser, and the browser is Chrome, and Chrome is Google, the entity that controls the measurement surface also controls the largest advertising platform competing for the same budgets. Advocates argue the privacy protections are genuine and necessary. Both things can be true simultaneously — and that is precisely what makes this so hard to resolve.

For brand teams in Southeast Asia, the practical implication is that any measurement framework built primarily on Google’s Attribution API is a framework where a single party controls both the ruler and what gets measured. Clean rooms, first-party data partnerships with platforms like Shopee or LINE, and probabilistic identity graphs from independent vendors are not optional hedges — they are the actual strategy.

Why Unilever’s Singapore Appointment Is a Signal, Not Just a Headline

Unilever’s decision to name Pinkustar Borah as Chief Digital & Technology Officer for its International business, based in Singapore, is worth reading as more than a personnel note. Borah is a nearly two-decade Unilever insider taking on his first international assignment in a role that spans digital and technology together — not separately.

The structural choice matters. Brands that separate digital marketing from technology infrastructure tend to build measurement stacks that marketing can interrogate but not actually own. Centralising both functions under one mandate, in Southeast Asia’s largest digital consumer market cluster, suggests Unilever is treating identity, data infrastructure, and media execution as a unified problem. That is the correct instinct. The brands that will navigate the cookieless transition — and the Attribution API debate — without losing material signal are the ones where the CMO and CTO are working from the same architecture diagram.

What Southeast Asian Brands Should Actually Do With This

Three moves that are worth accelerating in light of this week’s signals:

Audit your Network dependency. If more than 30% of your programmatic spend flows through Google Network inventory, model what a 15–20% further contraction in that supply looks like for your CPMs and reach. The contraction is not hypothetical — it is already in the earnings data.

Don’t wait for the W3C to resolve the Attribution API debate. It will not resolve cleanly or quickly. Build a parallel measurement track using first-party signals — email engagement, CRM match rates, platform-native conversion APIs from Meta, TikTok, and Shopee — so you are not flying blind if Chrome-based attribution shifts under you.

Treat identity infrastructure as a board-level investment, not a tech team to-do. Unilever’s structural move in Singapore reflects this. The organisations that will have durable measurement capability in 2027 are the ones making infrastructure decisions now, not after the deprecation announcement lands.

Key Takeaways

• Google’s Network decline is an open-web liquidity problem — brands should diversify programmatic supply chains toward platform-native and first-party-enabled inventory now.
• The W3C Attribution API fight is fundamentally about who controls measurement architecture; independent identity and clean room solutions are the hedge, not the contingency.
• Unifying digital and technology leadership under one remit — as Unilever has done in Singapore — is the organisational prerequisite for owning your measurement stack in a cookieless environment.

The deeper question this week raises is whether the open web as an advertising surface is entering a managed decline — not a cliff edge, but a slow compression that favours walled gardens and punishes brands that did not build first-party data moats five years ago. For Southeast Asian markets where platform ecosystems are already dominant and mobile-first behaviours make walled gardens stickier, the open web may have less runway than global averages suggest. The question worth sitting with: if Google’s own earnings are telling you to diversify, what are you waiting for?

At grzzly, we work with growth teams across Southeast Asia on exactly this intersection — identity strategy, measurement infrastructure, and programmatic diversification before the next platform shift makes it urgent.
