AEO, GEO & LLMO Companies in Barcelona

Barcelona’s tech scene has always been quietly ambitious. It’s not the kind of city that shouts about innovation, it just builds it. You see it in the startups tucked around Poblenou, in the digital studios balancing design with data, and in the new wave of agencies figuring out what visibility means in an AI-first world.

AEO (Answer Engine Optimization), GEO (Generative Engine Optimization), and LLMO (Large Language Model Optimization) are no longer experiments here, they’re becoming the core of how brands stay relevant. The companies leading this shift aren’t chasing trends; they’re aligning strategy, structure, and storytelling so that brands can show up naturally inside AI systems like ChatGPT, Gemini, and Perplexity.

In this article, we’ll look at the Barcelona teams shaping that space, the ones building search strategies that feel less like gaming algorithms and more like communicating with them.

1. Lengreo

At Lengreo, we spend a lot of time thinking about how search really works now. It’s not just about keywords anymore; it’s about how AI understands and delivers information. That’s where AEO (Answer Engine Optimization), GEO (Generative Engine Optimization), and LLMO (Large Language Model Optimization) come in. We help brands stay visible when people aren’t just searching but asking questions inside tools like ChatGPT, Gemini, or Perplexity. For us, it’s about shaping content and structure so businesses can show up naturally in these new types of searches.

Working with Barcelona-based clients has given us a clear view of how diverse and fast-moving the digital scene here is. Local businesses are curious but practical; they want strategies that actually translate into visibility and conversations, not just rankings. Whether it’s a SaaS startup in Poblenou or a creative studio in Eixample, we build strategies that bridge traditional SEO with AI-focused optimization. It’s a mix of structure, clarity, and real collaboration, no jargon, just thoughtful digital work that keeps up with how search is evolving.

2. SEOcom Agency

SEOcom is a digital marketing company that’s been around long enough to see SEO shift from keyword stuffing to answering real questions. These days, they focus on helping brands stay visible in the world of AI-driven search, blending classic SEO logic with newer ideas like AEO, GEO, and LLMO. They don’t overcomplicate things; their approach usually comes down to understanding what users actually need and how algorithms interpret that intent.

They’ve built their reputation on practicality. The team tends to work closely with clients to shape strategies that feel grounded rather than theoretical. Whether it’s optimizing content so AI systems like ChatGPT can understand it, improving site structure, or finding more natural ways for brands to show up in generative search, they approach it like people who actually enjoy solving puzzles, not selling solutions.
