Why is BIGSEO your ideal AI SEO agency?

Pioneers in SEO for ChatGPT and LLMs
We are one of the first SEO agencies to adapt our strategies to the new search ecosystem based on language models. While others continue to focus solely on traditional Google, at BIGSEO we have taken the step towards where user attention is really happening: ChatGPT, Gemini, Claude, Perplexity, Copilot…
We know how these models interact with content, what sources they use, how they interpret information, and what signals help them decide who to cite in their responses. Being a pioneer isn’t just about being first; it’s about understanding how something works and mastering it before anyone else.
Experts in visibility within generative AI systems
Today, when a user asks a question on ChatGPT, they are not looking for a website: they expect a direct, reliable, and up-to-date answer. And if your brand appears in that answer, you have gained more than a visit: you have gained authority.
At BIGSEO, we work to ensure that your name, services, or products are included in AI-generated responses. We apply semantic optimization techniques, context enrichment, trainable structures, and content relationships that increase your chances of being cited as a source.
It’s no longer just about positioning yourself, but about being the answer.


Customized SEO plans based on product or service type
Each AI model processes content differently. Gemini prioritizes structure and authority; ChatGPT values naturalness, context, and frequency; Perplexity relies on active sources with cross-references.
That’s why at BIGSEO we don’t apply a generic strategy: we analyze your product type, your ideal customer, your technology or expertise, and design a specific SEO plan to appear in the generative AI environments most relevant to your business.
We don’t work to get you indexed by Google. We work to get artificial intelligence to understand you, quote you, and recommend you.
Focus on results: presence in AI, not just search engines
Traditional SEO is measured in impressions, clicks, and web traffic. In the new SEO for AI, what matters is being present when the user does not click, but receives a response.
Our approach does not seek only to attract visitors, but to make your brand seen as a benchmark in AI-generated responses.
With BIGSEO, you go from being an option in the results… to being the source in the answers.

SEO services to appear in ChatGPT, Gemini, and Google Overviews
SEO for generative artificial intelligence
We work to ensure that your brand is understood and displayed by the leading generative AI models. These systems do not crawl content like traditional Google: they learn it, incorporate it, and use it to generate responses.
That’s why we create trainable content with optimized semantic structure, coherent thematic linking, and contextual authority.
Our mission is to ensure that your brand is not only visible, but also becomes a relevant source that language models choose as a reference when answering complex questions.
SEO for ChatGPT and OpenAI platforms
When someone asks a question in ChatGPT, the model generates a response based on millions of sources, prioritizing those that have been trained, updated, and validated.
At BIGSEO, we know the signals that GPT uses to decide what to mention. That’s why we optimize your content, articles, external mentions, public profiles, reviews, and data structures so that they are absorbed and used by ChatGPT.
From indirect prompts to texts that trigger specific responses, we know how to make your business appear within the world’s most widely used conversational flow.
SEO for Google Overviews (SGE)
Google Overviews (formerly SGE) represents an evolution of the classic search engine: it no longer displays only links, but answers generated directly by AI.
To appear there, it is not enough to have a good page: Google must be able to understand, summarize, and extract your content as part of a rich response.
At BIGSEO, we write, structure, and link your content so that Google considers it worthy of inclusion in those smart snippets. So, instead of competing with 10 links, you lead the response that users see directly at the top of the search engine.
SEO for Gemini, Copilot, Perplexity, etc
Each generative AI platform has its own architecture, but they all share one thing in common: they need clear, up-to-date, cited, and trainable content in order to respond correctly.
At BIGSEO, we develop multi-platform strategies that simultaneously position you on Gemini, Copilot, Perplexity, Claude, and other emerging AI engines.
We optimize your entire digital presence (website, blog, mentions, directories, networks, media appearances) so that, regardless of which assistant the user asks, your brand will be among the options that artificial intelligence will display and recommend.
Real benefits of SEO with AI and LLMs
We do not believe in generic strategies or prefabricated solutions that only waste resources.
Good SEO for AI can transform the way your business is perceived, mentioned, and recommended. By optimizing your digital presence so that language models such as ChatGPT, Gemini, or Perplexity “read” you and use you as a source of information, you manage to be present right at the moment when the user receives the answer.
This not only improves your visibility, but also positions your brand as a reliable and relevant reference in your sector, generating a competitive advantage that is difficult to replicate.
