El Nacional Unlocks 11% RPM Uplift with Pubstack’s Server-Side Technology
by on 27th May 2025 in News
El Nacional, a leading digital news outlet in Catalonia, successfully increased its RPM by up to 11% with Pubstack’s server-side integration, delivered through One, Pubstack’s full-stack monetisation manager. The integration, activated in under two minutes, enabled the media outlet to scale its programmatic revenue significantly without additional technical resources.
El Nacional, already recognised for high-quality editorial content and mature monetisation strategies, faced challenges due to natural constraints in the client-side architecture, restricting how many demand partners they could activate without negatively impacting latency and page performance. Pubstack enabled the publisher to rapidly connect demand partners to a server-side setup, doubling their SSP coverage and significantly improving bidding efficiency, latency, and performance transparency.
"Activating Pubstack’s server-side solution took just minutes, without requiring any engineering support. Its ease of use and immediate impact allowed us to test and scale new demand sources quickly, directly translating into an 11% RPM uplift and a 7% increase in overall programmatic revenue," said Àlex Rodríguez, head of programmatic at El Nacional. "We now have greater visibility and control, ensuring faster auctions, better Core Web Vitals, and ultimately a stronger monetisation strategy."
The server-side shift notably improved performance for demand partners, including Pubmatic, Ogury, and GumGum, achieving bid rate increases of up to 44%.
Nicolas Guilloteau, country manager Southern Europe at Pubstack, emphasised the collaboration’s success: "El Nacional’s results perfectly illustrate the immediate value publishers can unlock with server-side monetisation. By eliminating latency bottlenecks and enabling a broader range of SSPs, Pubstack ensures publishers not only improve auction performance but also future-proof their revenue growth without compromising user experience or Core Web Vitals. We're proud to support El Nacional in reaching new monetisation milestones."
With these results, El Nacional positions itself as an innovator in digital publishing, leveraging Pubstack's advanced monetisation tools to continually enhance both advertising revenue and user experience.You can read the full use case here.
