Quick answer
Technical SEO configuration for AI includes three pillars: 1) llms.txt file in the site root to tell LLMs which content to prioritize. 2) Server-Side Rendering (SSR) so AI bots see the full HTML. 3) Schema Markup (JSON-LD) to structure information. At SEO7.ES we implement these techniques from Valencia for all Spain, with a response in 24-48h.
In this comprehensive guide we break down the technical SEO configuration oriented to artificial intelligence. We will cover three fundamental areas: llms.txt, a text file that acts as a 'robots.txt for LLMs', telling models like GPT or Claude which pages or fragments to prioritize. Server-Side Rendering (SSR), a server-side rendering technique that ensures content is available in the initial HTML, facilitating indexing by AI crawlers. And Schema Markup, using Schema.org vocabulary in JSON-LD format to provide semantic context to search engines and language models. Each section includes practical examples, recommended tools and performance data. At the end, you will find an executive summary and a frequently asked questions section. This guide is based on our experience at SEO7.ES, an agency based in Valencia with clients throughout Spain.
The llms.txt file is a plain text resource located in the domain root (e.g., mydomain.com/llms.txt) that provides large language models (LLMs) with a list of URLs and content fragments they should prioritize when answering queries. Its structure is simple: each line can be a full URL or a section marker. To create it, identify the most relevant pages of your site (home, products, services, key blog) and order them by importance. You can include an optional descriptive title in brackets. For example: 'https://example.com/home [Home page]'. You can also add comments with #. Place the file in the root and verify its accessibility. Tools like Screaming Frog can help you audit URLs. At SEO7.ES we recommend updating the llms.txt every time you add important content.

Server-Side Rendering (SSR) generates the full HTML on the server and sends it to the client, unlike Client-Side Rendering (CSR) which builds the DOM in the browser using JavaScript. For AI bots, which often do not execute complex JS, SSR is crucial because the content is already present in the initial HTML. This improves indexing, reduces crawler bounce rate, and speeds up perceived load. Additionally, language models that extract information from web pages find textual content more easily. According to a Think with Google study, pages with SSR can reduce indexing time by up to 50%. At SEO7.ES we implement SSR with frameworks like Next.js or Nuxt.js, ensuring all critical content is available without relying on JavaScript.
| Feature | SSR | CSR | Impact on AI |
|---|---|---|---|
| Content in initial HTML | Yes | No (empty or loader) | AI bots see immediate content |
| JavaScript execution | Not required | Mandatory | AI crawlers may not execute JS |
| Indexing speed | Fast (hours) | Slow (days) | Google recommends SSR for critical content |
| User experience | Good (less time to interactive) | Variable (depends on network) | Improves Core Web Vitals metrics |
Schema Markup, especially in JSON-LD format, provides semantic metadata that helps search engines and AI models understand the context of your content. For example, marking an article as 'Article' with properties like 'headline', 'author', and 'datePublished' allows AI to extract precise information. To implement it, identify the content types on your website (Product, Event, FAQ, etc.) and generate the corresponding JSON-LD. You can use tools like Google's Structured Data Markup Helper or Schema Markup Generator. Insert the code in the <head> or <body> section of your page. Validate with Google's Rich Results Test. According to a Statista survey, 58% of websites using Schema report improved visibility. At SEO7.ES we integrate Schema dynamically using CMS templates or directly in code.
