10 content optimisation tips for generative AI and LLM in 2025

Answers to web users' questions are being generated directly by language models, and websites are losing visibility. With the rise of GEO(Generative Engine Optimization), websites are looking to adapt their content to appeal to generative AIs. Here are 10 optimisations you can implement to maximise your chances of being included in their responses.

1. Careful headings and sub-headings (Hn)

The structure of the content and the hierarchical headings (H1, H2, H3) enable language models to understand the subject and take in the information.

Recommended GEO optimisation:

• Use titles that include your main keywords.
• Structure each section with a single subject per title.
• Avoid vague wording such as "Miscellaneous" or "General conclusion".

2. Responding to search intent from the outset

Generative AIs work like Internet users in a hurry. They are looking for a direct answer to the question posed. If your content takes too long to provide the information they are looking for, it may not be included in the results generated.

Recommended GEO optimisation:

• Formulate the main answer in the first few lines of your article or paragraph (inverted pyramid method).
• Then develop explanations and details.
• Use simple phrases such as: "Yes, it is possible to optimise content for LLMs by structuring its titles and adding an FAQ". These can be used by the language models.

3. Using lists, tables and boxes

Generative AI easily extracts information when it is presented in the form of lists or tables. The content is more readable and easily reused by language models in their responses.

Recommended GEO optimisation:

• Use bulleted or numbered lists.
• Create comparative tables to summarise data.
• Add boxes or highlight blocks to emphasise a definition, a key figure or a piece of advice.

4. Short paragraphs and one idea per block

Language models find it easier to analyse content broken down into short blocks. A paragraph that mixes several ideas or exceeds ten lines becomes difficult to interpret... for both AI and humans.

Recommended GEO optimisation:

• Limit each paragraph to 3-4 sentences maximum.
• Deal with a single idea per paragraph.
• Use connectors to guide comprehension, such as "To summarise, Here are the steps, To remember...".

5. Integrate an AI and user-oriented FAQ

Even though Google is displaying FAQs less often in its results, they are still appreciated by generative AI and by readers. FAQ content is structured in the form of questions and answers and corresponds to the logic of a prompt.

Recommended GEO optimisation:

• Add a FAQ at the bottom of your articles with 3 to 5 key questions that your users ask.
• Write short, factual and direct answers that are easy for an AI to quote.
  Use Schema.org mark-up

6. Add examples, figures and case studies

Generative AI values content that is based on tangible elements. Examples and statistics reinforce the credibility of the text and make it easier for language models to extract.

GEO optimisation recommended:

• Include recent, sourced statistics
• Illustrate your explanations with practical examples or mini-case studies.

7. Quote reliable sources and indicate the author's name

Generative AI seeks to highlight credible content. To this end, mentioning your references and signing your articles will strengthen your legitimacy and your chances of being quoted in the responses generated.

Recommended GEO optimisation:

• Add quotes from experts or recognised publications (studies, reports, specialist media).
• Insert links to reliable sources to contextualise your comments.
• Identify the author of the article (name, position, expertise).
• This optimisation contributes to E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness), an increasingly important criterion for the organic visibility of a website.

8. Update your content regularly

Language models favour recent, reliable and up-to-date information. Keeping your pages up to date sends a strong signal to traditional search engines and AI.

Recommended GEO optimisation:

• Add a visible update date to your articles and regularly check and correct your internal and external links.
• Enrich your existing content with new data, trends or examples.

9. Optimise the site's internal linking and architecture

Isolated content carries little weight in the eyes of search engines and generative AI. On the other hand, well-connected pages reinforce thematic coherence and facilitate navigation, which increases the likelihood that your content will be considered as a reference.

Recommended GEO optimisation:

• Add contextual internal links between your articles to create thematic clusters.
• Each important page should be accessible in less than 3 clicks from the home page.
• Include outbound links to trusted sites to show that your content is part of a "credible" ecosystem.

10. Test your content in ChatGPT, Perplexity or Gemini

The best way to find out whether your content is picked up by generative AI is to test it. By querying ChatGPT, Perplexity, Gemini or Bing Copilot on your themes, you can check whether your articles appear, how they are interpreted and what improvements are needed.

Recommended GEO optimisation:

• Type in queries close to those of your users to see if your pages are cited.
• Analyse the references displayed (are they your content or that of your competitors?).
• Then adjust your articles (structure, clarity, addition of data or examples) to increase your chances of being picked up.
