Websites optimised for SEO and AI search
We build websites that rank on Google and get cited by ChatGPT and Perplexity: technical SEO, structured data and GEO. From €3,500, delivered in 4-6 weeks.
Evicron, an AI and custom software studio based in Barcelona and founded in 2019, builds websites optimised for both SEO and AI search: sites that rank on Google and get cited in answers from ChatGPT, Perplexity and Gemini. We combine measurable technical SEO — Core Web Vitals, structured data, hreflang — with GEO (Generative Engine Optimization), a layer most agencies don’t offer yet. From €3,500, delivered in 4-6 weeks.
Search is no longer just Google
A growing share of your customers never open Google at all: they ask ChatGPT, Perplexity or Gemini and act on the answer. These engines don’t return ten blue links — they cite two or three sources and recommend specific companies. If your website can’t be read, understood and quoted by a language model, you’re invisible on that channel, no matter how well you rank on Google.
The good news: technically sound websites start with an advantage. What Google’s crawler rewards — speed, structure, semantics — an LLM rewards too.
What we deliver: technical SEO + GEO
Every website we ship is built on two complementary layers.
Technical SEO, the foundation Google measures:
- Core Web Vitals in the green: static or hybrid builds with Astro or Next.js that load in milliseconds.
- Schema.org structured data: Organization, Service, FAQPage, Product, BreadcrumbList — whatever fits your business.
- hreflang and multilingual architecture done properly, so each market gets the right version.
- Sitemaps, canonicals, metadata and Open Graph handled from the first commit.
GEO (Generative Engine Optimization), the layer AI engines actually read:
- llms.txt: a root-level file that summarises your business in a format language models can parse.
- Citable content: self-contained paragraphs, rich in entities and concrete facts, that an assistant can quote without extra context.
- Structured FAQs with FAQPage markup, written the way people actually phrase questions to ChatGPT.
This isn’t theory: Evicron’s own website applies everything above. So do our clients’ sites. Plata Garage ships 9 types of structured data, llms.txt and cookieless analytics; on Forcadell’s real-estate portal we apply technical SEO and AI SEO across more than 2,300 trilingual listings updated daily.
How we work
Four phases with a fixed quote: Discovery (a free initial consultation, including how your company shows up today in search engines and AI assistants), Design, Development in weekly sprints — first clickable demo in week 2 — and Launch and support. A complete corporate website ships in 4-6 weeks.
If you need more than a website — a portal, a client area, ERP integrations — we handle it as custom software with the same SEO/GEO layer built in.
Why Evicron
We’re a small Barcelona studio with over 200 delivered projects across 12 industries, working remotely with clients all over Europe. No template reselling: every site is built with React, Astro or Next.js, and the code is yours — full Git repository, no lock-in. We reply within 24 hours.

Frequently asked questions
What is GEO (Generative Engine Optimization)? +
GEO is the practice of optimising a website so that generative engines like ChatGPT, Perplexity or Gemini cite it in their answers. It combines self-contained, citable content, structured data and files such as llms.txt. Evicron applies GEO to every website it delivers — including its own — as a layer on top of classic SEO.
How do I get ChatGPT to recommend my business? +
AI assistants cite websites with clear, verifiable, well-structured information: direct answers, properly marked-up FAQs, Schema.org data and an llms.txt file that summarises your business. Evicron implements this full layer; on Plata Garage's website we publish 9 types of structured data plus llms.txt so AI search engines can understand and cite their catalogue.
How much does an SEO-optimised website cost? +
At Evicron, corporate websites with technical SEO and GEO included start at €3,500, with a fixed quote after a free discovery consultation. Typical delivery takes 4 to 6 weeks, with the first clickable demo in week 2.
What is llms.txt? +
llms.txt is a standard file published at the root of a website that summarises its content in a format language models can read — similar in spirit to what robots.txt does for crawlers. It helps ChatGPT, Perplexity or Claude understand what you offer and cite you accurately. Evicron includes it by default in every web project.
Does GEO work for multilingual websites? +
Yes. With correct hreflang tags and native content per language, both Google and AI search engines serve the right version to each user. Evicron maintains Forcadell's trilingual real-estate portal — over 2,300 listings — applying technical SEO and AI SEO in Spanish, Catalan and English.
