Únete a Search Barcelona para aprender sobre SEO en China, como trabajamos con AI y SEO más un juego SEO en The Hot Seat ## ¡Bienvenido a Search Barcelona! Prepárate para una tarde increíble en persona donde exploraremos en SEO en China, la revolución de la IA aplicada al SEO y, un juego interactivo por que se llama "The SEO Hot Seat". No te pierdas esta oportunidad única de conectar, compartir y llevar tu SEO al siguiente nivel con expertos y apasionados del sector. Our next Search Barcelona will be in Spanish. We will have two talks, one by [Natalia Witczyk](https://www.eventbrite.com/e/entradas-search-barcelona-seo-in-china-seo-con-ai-y-the-seo-hot-seat-1986508535505?aff=oddtdtcreator&keep_tld=true) and one by [David Carrasco Pamies](https://www.linkedin.com/in/david-carrasco-pamies/ "https://www.linkedin.com/in/david-carrasco-pamies/"). **SEO Made in China: lecciones de marketing de mi 6 meses en Oriente** Esta charla explora cómo las superapps y los ecosistemas cerrados han redefinido el marketing digital en China. Natalia Witczyk pasó 6 meses en China aprendiendo sobre el mundo sin Google. Analizaremos cómo es el sistema digital de ahí ahora mismo y qué procesos acelerados impulsan sus tendencias. Descubre las claves de un mercado que opera a una velocidad y escala totalmente distintas, y aprende como aplicar esos conocimientos a tu estrategia de marketing. **Natalia Witczyk** es una consultora SEO independiente multilingüe, especializada en SEO Internacional. Es la fundadora de la consultora Mosquita Digital. Ha pasado más de 11 años creando e implementando estrategias SEO para motores como Google, Bing, Yandex y Baidu. Es nativa de Polonia y tiene experiencia profesional en Reino Unido, España y últimamente en China. **Gnōthi seautón (Know Thyself) - *Como descubrir y corregir lo que la IA dice de tu marca*** La charla explora por qué el SEO como disciplina ha ido perdiendo el contacto con el ser humano que está detrás de la búsqueda y qué hace falta para recuperarlo. Arranca con una mirada antropológica y lo conecta con lo que está pasando ahora mismo: la IA ha commoditizado el contenido, ha hecho visible la incoherencia de marca y ha expuesto un hueco que la mayoría de empresas no saben que tienen. No es una charla teórica. Incluye un caso de estudio real con resultados, un framework que la audiencia puede aplicar el lunes y un método sencillo con el que los asistentes podrán comprobar en directo la "deuda de identidad" de su propia marca: la distancia entre quiénes son y cómo los perciben los usuarios, los buscadores y los sistemas de IA. El tono es provocador pero inclusivo. Sin señalar con el dedo, sin catastrofismo. El objetivo es que la sala piense de forma diferente sobre lo que realmente es el trabajo de SEO y se vaya con algo concreto que hacer al respecto. David hablara cómo llegar al usuario actualmente, el impacto de IA, keyword research, y estrategia. Takeaways: 1\. Cómo el SEO perdió al usuario y por qué eso importa más que nunca\. 2\. Qué es la deuda de identidad y por qué la IA acaba de hacerla visible\. 3\. Un proceso real para volver a mirar al ser humano que busca\. **David Carrasco Pamies** es consultor de SEO estratégico con más de 15 años de experiencia en mercados internacionales. Fundó, escaló y vendió una empresa tecnológica: una experiencia que marcó su forma de entender el crecimiento, el producto y la visibilidad digital. Le obsesiona entender cómo los buscadores y los sistemas de IA deciden quién se ve y quién no. Generalista por convicción, conecta ideas entre SEO, estrategia de marca, psicología y tecnología. Speaker y formador en conferencias internacionales de SEO. We will have two talks, both in Spanish and then an SEO game called "The Hot Seat". The Hot Seat" Real SEO nightmares. One mic. Ninety seconds. Could you solve them under pressure? How it works: \- David presents 5 absurd\-but\-real client scenarios on screen \(think: "Your intern used AI to publish 50\,000 pages without telling anyone — traffic is up 400% but Google just started deindexing\. What do you do Monday morning?"\)\. \- For each scenario\, a volunteer takes the hot seat and has 90 seconds to pitch their strategy to the room\. \- Then David asks: "Would anyone do it completely differently?" A second person gets 60 seconds to counter\. \- The room votes on which approach wins\. David closes each round with his take or reveal what actually happened\. \- Five rounds\, five nightmares **We’re pleased to announce that Collaborator is the headline sponsor of the upcoming Search Barcelona event.** [Collaborator](https://collaborator.pro/?utm_source=searchldn&utm_medium=offline&utm_campaign=search_barcelona&utm_content=post "https://collaborator.pro/?utm_source=searchldn&utm_medium=offline&utm_campaign=search_barcelona&utm_content=post") is a digital PR marketplace that helps SEO specialists, marketers, and PR teams increase online visibility by guest posting and digital PR content distribution across trusted websites, with transparent SEO metrics, including data from Google Analytics and Google Search Console.

Buenas! (English below) Cada día aparecen formas nuevas de aprender español, (y otros idiomas) apps nuevas, métodos de gramática, IA, videos de profes explicando cosas, y están todas genial. Si te ayudan a entender más y a hablar mejor están genial. El plan de este grupo es mejorar tu español con juegos, actividades reales y ejercicios para hablar más. Con la excusa de los juegos y las actividades corregimos la mayoría de errores: Palabras difíciles, confundir pasados, preposiciones, verbos que significan muchas cosas, ser y estar en pasado, frases con dos verbos o mas, subjuntivo, expresiones coloquiales, y también los errores "culturales”: ¿De que forma usamos los españoles el idioma en diferentes situaciones? La gente que participa es (casi siempre) muy simpática, y normalmente deja reviews muy positivas de las clases. Si te cuadra el plan ven a practicar tu español y hablamos de comida, de viajes, de trabajo, de cultura, de Internet, de temas locales, de noticias y de muchas más cosas. Para participar hay una contribución de solo 10€ por persona/ clase de 2 horas (materiales incluidos, bebidas no incluidas) o de 30€ por 4 clases. Vente y hablamos. Rafa. \-\-\-\- Hi! Every day there are new ways to learn Spanish, (or any language) new apps, grammar methods, AI, teachers explaining things on videos, and they are all great. If they help you to understand more and to speak better, they are great. The main plan in this group is to improve your Spanish with games, real activities and exercises to speak more. All the games and activities are a good excuse to correct the most difficult/ frequent mistakes: Difficult words, confusing past tenses, prepositions, verbs that mean many things, ser and estar in the past, sentences with two or more verbs, subjuntive, colloquial expressions, and also “cultural" mistakes: How we, Spanish people, use the language in different situations? People participating are (almost always) very nice, and usually leave very positive reviews of the classes. If the plan fits you, come to practice your Spanish and we'll talk about food, travel, work, culture, Internet, local issues, business, news and many more things. There is a contribution to participate of only €10 per person/2-hour class (materials included, drinks not included) or €30 for 4 classes. Let´s talk. Rafa.

**Hello, fellow DevOps enthusiasts 🤓** On **May 7th**, we'll meet again for a couple of insightful talks, hosted by **[Dynatrace](https://www.dynatrace.com/)**! 📍**Location**: Avda Diagonal 211 \- 14th floor\, Torre Glòries\, Barcelona \| [https://maps.app.goo.gl/22q31ECkaW7BzDMD8](https://maps.app.goo.gl/22q31ECkaW7BzDMD8) \-\-\-\-\-\- 📅 **Agenda** * **18:30 - 18:40** Welcome from the hosts * **18:45 - 19:30** "The microservices kool-aid and what that means for SREs" * **19:30 - 20:15** "Observability in the AI-Native DevOps Age" * **20:15 - 21:00** Networking & Snacks \-\-\-\-\-\- **🎤 Talks & Speakers** * **Title: "The microservices kool-aid and what that means for SREs"** * **Speaker**: [Csaba Almási](https://www.linkedin.com/in/csaba-almasi/) - *Staff Platform Engineer at [Neonomics](https://www.neonomics.io/).* * **Duration**: 30-45 mins * **Abstract**: For years, the industry has treated microservices as the default architecture for any scaling project, but for SREs, this "Kool-Aid" often comes with a bitter aftertaste. This session moves past the hype to examine the true operational tax of service proliferation, specifically focusing on how fragmented architectures drive up observability costs and create silent performance bottlenecks through network overhead and resource contention. We will dive deep into the technical signals that reveal a "distributed monolith"—a system that shares the complexity of microservices but retains the rigid coupling of a legacy app—and provide a rubric for identifying when an architecture has become more of a liability than an asset. Beyond the theory, we’ll explore practical guidelines for determining when to actually decompose a monolith and, perhaps more importantly, when to move in the opposite direction. Using real-world examples from the field, we will walk through the architecture and design decisions behind both successful service extractions and strategic consolidations of over-engineered distributed systems. You’ll walk away with a framework for balancing technical depth with operational sanity, ensuring your architecture evolves based on performance data rather than industry trends. * **About**: Csaba Almási is a Staff Infrastructure Engineer at Neonomics, where he focuses on building reliable platforms and maximizing the business impact of observability. With extensive experience in SRE and distributed systems, he specializes in bridging the gap between technical architecture and operational efficiency in the fintech sector. \-\-\-\-\-\- * **Title: "Observability in the AI-Native DevOps Age"** * **Speaker**: [Andreas (Andi) Grabner](https://www.linkedin.com/in/grabnerandi/) - *CNCF Ambassador, Book Co-Author, and Fellow DevRel at [Dynatrace](https://www.dynatrace.com/)* * **Duration**: 30-45 mins * **Abstract**: *AI is here to stay!* *The question is: How to make it an efficient DevOps partner for the human to build, test and operate software?* The answer is simple: Just like humans, the AI can use observability to understand and optimize the impact of generated and deployed code and configuration. In this talk you learn the path through three important lessons on how observability as you know it is changing to become useful for the Human and the AI as we enter the AI-Native Age. **1.** **The Observability Primer**: “What’s different in observing an app, an AI or a workflow?" **2.** **The AI Delivery Lifecycle**: “How can my AI becomes better with observability?” **3\. Cost and Impact**: “How can we speed up while staying within budget?” You will walk away and know how to best apply open standards like OpenTelemetry and OpenLLMetry to get insights and optimize your own usage of AI. Whether its for coding, automation or to provide it as a business feature! * **About**: Andreas Grabner has 20+ years of experience as a software developer, tester, and architect, and is an advocate for high-performing cloud-scale applications. He is a CNCF ambassador, a contributor to the CNCF project keptn, a Co-Author of Platform Engineering for Architects, and a Fellow DevRel at Dynatrace. Andreas is also a regular contributor to the DevOps, Platform Engineering, and Cloud Native communities and a frequent speaker at technology conferences.

A special edition meetup with a very special guest! International speaker Daniel Afonso will talk about the Framework wars and what he learned from them! Don't miss out! 🚀 ────────── **18:30: Welcome** **18:45 Intro by Host Neciu Dan** **19:00 React-Driven Development: Career Lessons from the Framework Wars** Speaker: Daniel Afonso, Senior Developer Advocate at PagerDuty "No one uses what I built!" "Why can't I get support to do this?" "I don't even know why we're using that?" "Why am I always the one doing everything?" Sound familiar? The truth is, friction is ever-present in our careers — in our influence, processes, relationships, and even the code we ship. But we're rarely taught how to handle it. Here's the fun fact: React's history is full of lessons in dealing with friction. From the early skepticism around JSX and the Virtual DOM to the chaos of Server Components, the React team has navigated many friction points you'll face: skeptical stakeholders, unclear messaging, delayed initiatives, and the challenge of getting buy-in. So let's recap the highlights since its birth to the latest release, understand what React got right (and wrong), and extract practical takeaways you can apply to your career, team, and developer experience initiatives. Whether you're leading a team, building internal tools, or advocating for a technical decision, you'll leave with concrete strategies for driving change, building trust, and shipping initiatives that actually get adopted. **20:00: Drinks and networking!** Do you want to talk at this meetup?
