RAAS makes the case for rebalancing budgets toward the open web, highlighting relevance, transparency and creative opportunity

With the right strategy, the open web can rival platforms not by mimicking them, but by playing to its strengths: scale, diversity, and creativity.

For the last decade, walled gardens have dominated digital advertising. They offer scale, targeting, and the illusion of control. But cracks have been showing for years now: rising costs, limited transparency, and restrictions on data are leaving brands questioning their dependency.

The open web, often overlooked and undervalued, holds the key to balance. With the right strategy, it can rival platforms not by mimicking them, but by playing to its strengths: scale, diversity, and creativity.

The risks of over-reliance

When budgets sit disproportionately in walled gardens, brands lose visibility into spend, miss opportunities for creative expression, and hand over too much control to a single platform’s ecosystem. It’s a fragile strategy in an era demanding accountability.

Why the open web still matters

Across premium publishers, niche communities, and innovative formats, the open web offers richness that platforms can’t replicate. It’s where brand storytelling and diverse environments meet.

Relevance as the open web’s advantage

With impression-level optimisation, advertisers can bring the sophistication of platforms to the open web, but with greater transparency and creativity. Matching creative with context in real time allows brands to deliver messages that resonate, while supporting publishers with fair value.

The call to rebalance

The open web isn’t just surviving - it’s evolving. Brands that lean into relevance-driven strategies will discover that the open web can compete with, and even surpass, the walled gardens. 2025 should be the year of balance: the age of relevance.
