SIDN: Leading the Evolution of SEO in the AI Era

Being finalists at the European Search Awards 2026 is already a significant recognition in itself. But this year, for SIDN, it carries special meaning.

The company has been nominated in four key categories:

• Best Large SEO Agency
• Best Use of AI in Content
• Best AI Search Optimisation Campaign
• Best Use of AI in Search

This multiple recognition not only highlights the results achieved, but also reflects a deeper transformation: the evolution of SEO into a model fully integrated with artificial intelligence.

What this nomination means?

Being recognized in four categories within one of the industry’s most demanding awards reflects the company’s current transformation.

“Being nominated in four categories shows the extent to which artificial intelligence is embedded in everything we do. This is not just about isolated innovation, but a structural shift in how we understand SEO.”

— Cristian Betancort Niz, Head of Production and Operations

The European Search Awards represent a standard of excellence in the industry, and this recognition reinforces SIDN’s position as one of the players leading this change.

“Beyond the recognition, these awards give us the opportunity to pause and reflect on the journey. The evolution of SEO in recent years has been massive, and being part of it is something we truly value.”

Redefining SEO in the AI Era

Over the past 12–18 months, SIDN has driven a strategic transformation: evolving SEO into what they call Search AI/GEO.

This involves working on visibility not only in traditional search engines, but also in environments such as:

• Google AI Overviews
• LLM-based platforms (such as ChatGPT, Claude, etc.)
• Zero-click results
• Multimodal and entity-based experiences

The focus shifts from ranking alone to overall visibility across the entire search ecosystem.

Innovation at Enterprise Scale

One of the biggest challenges in modern SEO is innovating without losing consistency at scale. SIDN has tackled this by combining proprietary technology with strategic partnerships.

As a partner of platforms such as Google Ads, Google Cloud, and Reddit, the company has developed a model where:

• SEO, Paid Media, and AI operate as a single system
• Decision-making is driven by real-time data
• Organic and paid visibility reinforce each other

This approach enables operations across multiple markets while maintaining performance, control, and strategic consistency.

Real Business Impact

SIDN’s nominations are backed by tangible results.

Among its most recent projects:

• Iberdrola: A complete redesign of SEO and content strategy to compete in AI-driven search environments, improving visibility across both traditional results and generative platforms. This work supports the nominations for Best AI Search Optimisation Campaign and Best Use of AI in Content.
  
• Décimas (Think with Google case): Integration of media activation with AI and real-time stock data, achieving nearly a 50% increase in conversion rate, a 23% reduction in advertising costs, and sustained sales growth.
  
• Orange (MasOrange): In the context of the shift toward generative search, SIDN developed a pioneering approach to measuring visibility in AI-based search. This approach underpins the nomination for Best Use of AI in Search, showcasing its ability to redefine performance measurement in the new SEO era.

These cases demonstrate how innovation translates into measurable business outcomes.

Growth, Culture, and Stability

Beyond innovation, SIDN stands out for its organizational strength:

• Over 80% revenue growth in 2024
• Sustained growth over the past five years
• Client retention above 90%
• Employee turnover below 1.5%
• Average tenure exceeding 6 years

This stability has led the company to be recognized as a Great Place to Work in Spain and among the Top 10 Best Workplaces in Europe.

“Innovation is only sustainable when it is built on a strong foundation of team and culture. For us, both go hand in hand.”

— Isabel Vázquez, AI Solutions Manager

Overcoming Industry Challenges

The rise of generative AI has completely redefined SEO. Traditional strategies no longer guarantee visibility.

SIDN has responded to this shift through:

• Investment in proprietary AI-based technology
• Evolution toward entity- and intent-based models
• New metrics focused on visibility and influence
• Integration of SEO with content, data, and reputation

This transformation has required deep internal changes, from team training to process redefinition.

The result is a scalable model capable of succeeding in increasingly complex search environments.

Why SIDN Stands Out

The four-category nomination reflects a rare combination in the market:

• Ability to execute at international scale
• True integration of SEO, AI, data, and paid media
• Development of proprietary technology
• Proven business results
• Strong culture and organizational stability

While many companies are still adapting to the impact of AI, SIDN has already embedded this shift into its operating model.

Looking Ahead

The future of search will be defined by artificial intelligence and the fragmentation of access points to information.

SIDN has a clear goal: to continue leading this evolution and help brands adapt with control, strategy, and measurable results.

Being finalists in four categories at the European Search Awards 2026 is an important recognition — but also a driving force for what lies ahead.
