The Global Context: Internet Penetration and the Digital Divide

While the adoption of AI chatbots is soaring in many parts of the world, we need to consider the global digital landscape. The International Telecommunication Union (ITU) in its “Facts and Figures 2024” report, reveals that while an estimated 5.5 billion people are online, a staggering 2.6 billion people remain offline. This digital divide is not uniform and is influenced by several factors:

• Gender: A gender gap persists in internet use, with 70% of men online compared to 65% of women.

• Location: The urban-rural divide is a significant barrier to connectivity, with 83% of urban dwellers online compared to just 48% in rural areas.

• Age: Young people are more likely to be online, with 79% of those aged 15-24 using the internet.

Factor	Metric	Share (%)
Gender	Men online	70%
Gender	Women online	65%
Location	Urban dwellers online	83%
Location	Rural dwellers online	48%
Age	People aged 15-24 online	79%

For content creators, this data highlights the importance of creating accessible content. This includes not only making content mobile-friendly but also considering the language and reading level of the target audience. As global internet penetration continues to grow, so too will the potential audience for AI-optimized content.

The Rise of AI Search and Content Discovery

The integration of AI into search engines is another critical development that is reshaping the digital landscape. The Verge reported in Q1 2025 that Google’s AI Overviews now reach more than 1.5 billion people every month. This feature, powered by Google’s Gemini AI, provides users with AI-generated summaries of search results, often eliminating the need to click through to individual websites.

Similarly, Microsoft’s FY25 Q4 earnings call in July 2025 revealed that the Copilot family of AI assistants has surpassed 100 million monthly active users. This demonstrates the growing trend of users turning to AI for direct answers and information synthesis.

Platform	Metric	Value	Timeframe
Google AI Overviews	Monthly reach	1.5 billion	Q1 2025
Microsoft Copilot family	Monthly active users	100 million	July 2025

These developments have profound implications for content creators. The traditional SEO model, focused on driving clicks from search engine results pages (SERPs), is being challenged. In the age of AI search, the new goal is to have your content directly referenced and cited by AI models. This requires a shift in focus from keyword stuffing and backlink building to creating high-quality, authoritative and data-driven content.

The Crisis of Trust and the Opportunity for Factual Content

The Reuters Institute Digital News Report 2025 paints a sobering picture of the modern media landscape. Trust in traditional media is on the decline, while concerns about misinformation and disinformation are on the rise. The report found that 58% of respondents feel unsure about their ability to distinguish truth from falsehood in online news.

Metric	Value	Observed
Uncertainty distinguishing truth vs falsehood	58%	Reuters Institute 2025

This crisis of trust, however, presents a significant opportunity for content creators who are committed to accuracy and objectivity. AI models are trained on vast datasets of text and code and they are increasingly being designed to prioritize reliable and authoritative sources. By creating content that is well-researched, fact-checked and supported by data, you can increase the likelihood that your content will be used and cited by AI chatbots.
The report also highlights the growing influence of online personalities and influencers. While this can contribute to the spread of misinformation, it also underscores the importance of building a strong personal or brand reputation. By establishing yourself as a trusted authority in your field, you can increase the visibility and credibility of your content in the eyes of both human users and AI models.

Strategies for Ranking on ChatGPT and Other AI Platforms

Now that we have a clear understanding of the AI chatbot landscape, user behaviour and the evolving digital ecosystem, let’s dive into the actionable strategies for optimizing your content.

Prioritize Factual Accuracy and Data-Driven Insights

This is the cornerstone of any successful AI optimization strategy. Your content must be meticulously researched, fact-checked and supported by credible sources. Whenever possible, include data, statistics and citations to bolster your claims. This not only enhances the credibility of your content for human readers but also makes it more attractive to AI models that are designed to prioritize factual accuracy.

Create Comprehensive and In-Depth Content

In the age of AI, “thin” content that offers little value will be left behind. To rank on ChatGPT, you need to create comprehensive and in-depth content that covers a topic in its entirety. This means going beyond surface level explanations and providing detailed analysis, insights and examples. The more comprehensive your content, the more likely it is to be seen as an authoritative source by AI models.

Clarity and Scannability Trump Complexity

In the race to be cited, the most easily digestible content wins. LLMs are not impressed by dense academic prose or complex jargon. They are looking for clear, concise and well-formatted information that can be quickly extracted and synthesized.

The Data:

• SEOmonitor’s analysis points out that well-organized content with a logical flow and easy-to-scan formatting helps AI systems extract key information more effectively.

• Firsthand analysis shared by experts in Search Engine Journal found that content making heavy use of bullet points, numbered lists and short paragraphs is favoured for inclusion in AI Overviews.

• While not a direct data point on AI, it’s a long-standing usability principle that clear and simple language (aiming for a 9th-10th grade reading level) serves the widest audience. This principle is magnified when the “reader” is a machine looking for unambiguous facts.

GEO Strategy:

• Write for Scannability: Break up long blocks of text. Use bullet points, numbered lists, bolded text and blockquotes to highlight the most important information.

• Prioritise Simplicity: Avoid jargon where possible and if you must use it, define it immediately. Write in a clear, direct and accessible style.

• Use the Inverted Pyramid: Place the most critical information and the direct answer to the user’s query at the beginning of your article, followed by supporting details and context.

Multimodality Provides Deeper Context

The most advanced LLMs, like Google’s Gemini or OpenAI’s ChatGPT, are inherently multimodal - they can process and understand text, images and video simultaneously. Providing rich, contextual media is an emerging and powerful signal for demonstrating comprehensive expertise.

The Data:

• While specific GEO data is still emerging, the technical capabilities of these models are clear. A February 2025 tutorial from DigitalOcean explains that multimodal AI systems generate richer results by fusing information from multiple input types. For example, they can analyze images and their corresponding text descriptions to develop a deeper understanding.

• The functionality of AI Overviews, which often include images and videos, demonstrates that Google is actively using non-text media to construct its answers.

• The rise of models that can process text, audio, video, images and code (like ChatGPT) means that providing content in multiple formats is no longer just for user experience, but for machine comprehension as well.

GEO Strategy:

• Optimize Your Images: Use unique, descriptive images, not just stock photos. Your alt text should be a literal description of the image and the filename should be relevant (e.g., ai-overview-chatgpt-ctr-data-chart-2025.png).

• Transcribe Your Videos: For all embedded videos, provide a clean, accurate transcript. This makes the spoken content fully accessible and indexable by AI crawlers.

• Create Explanatory Graphics: Use charts, diagrams and infographics to visually represent data and complex concepts. These are highly scannable and provide a concise summary that an AI can easily interpret.

Optimize for Natural Language as the Conversational Query Reigns Supreme

Users interact with AI chatbots in a conversational manner, using natural language to ask questions and seek information. To optimize your content for these queries, you need to think like a user. What questions are they likely to ask? What kind of information are they looking for? By anticipating these queries and structuring your content to provide direct and concise answers, you can increase your visibility on AI platforms such as ChatGPT, Gemini or Perplexity.

The Data:

• The BrightEdge May 2025 report identified a 7x increase in queries of 8 or more words. This is a clear indicator of the shift towards long-tail, highly specific and conversational search terms.

• A January 2025 analysis from Search Engine Journal highlighted that AI Overviews are more frequently triggered by long-tail keywords. Data from Ahrefs cited in the report shows a higher trigger rate for queries with three to four words compared to shorter queries.

• An OpenAI report published in September 2025 analyzing ChatGPT usage found that the two most common use cases are “Practical Guidance” (how-to advice, tutoring) and “Seeking Information”. Both of these categories are inherently question-based.

GEO Strategy:

• Answer Questions Explicitly: Structure your content with the most important question and its answer at the very top. Use clear, descriptive headings (H2s, H3s) that are framed as the questions your audience is asking.

• Mine “People Also Ask”: The “People Also Ask” section on Google is a goldmine for identifying relevant long-tail questions. Build content that directly and comprehensively answers these queries.

• Adopt a Q&A Format: For complex topics, use an FAQ format. This not only serves human readers well but also makes it incredibly easy for an LLM to extract a question-and-answer pair for its results.

Authoritative Sources are the Bedrock of AI Answers

As the Reuters report highlighted, trust is a precious commodity in the digital age. To rank on ChatGPT, you need to establish yourself as a trusted authority in your field. This can be achieved through a variety of means, including:

• Publishing high-quality content consistently: The more you publish, the more opportunities you have to be seen by AI models.
• Building a strong social media presence: Engaging with your audience on social media can help to build your reputation and drive traffic to your website.
• Guest posting on other authoritative websites: This can help to expose your content to a wider audience and build your backlink profile.

LLMs are designed to fight misinformation, causing them to heavily favour content from established, authoritative domains. While E-E-A-T (Experience, Expertise, Authoritativeness and Trustworthiness) has always been a cornerstone of good SEO, its role is now more critical and measurable than ever.

The Data:

• A November 2024 study by SE Ranking found that in 92.36% of cases, AI Overviews link to at least one domain that also ranks in the top 10 organic results. This shows a strong reliance on sites that have already established traditional authority signals.

• The same study noted that large, authoritative domains like Wikipedia.org and Healthline.com are overwhelmingly favoured as sources, reinforcing the idea that LLMs use domain-level trust as a primary filter.

• Content that clearly demonstrates expertise such as detailed author bios with credentials, transparent editorial policies and links to supporting primary sources is consistently preferred by AI. SEOmonitor’s September 2025 analysis of AI ranking factors highlights that a clear connection between the author and the topic is a vital signal for establishing credibility with AI systems.

GEO Strategy:

• Show, Don’t Just Tell, Your Expertise: Ensure every article has a clear author byline that links to a detailed bio page. This page should list qualifications, relevant experience and links to other publications or professional profiles.

• Build Your Knowledge Graph: Invest in building your brand as a recognized entity. This includes having a robust Wikipedia presence (if applicable), consistent information in business directories and a well-optimized “About Us” page that clearly states your organization’s expertise.

• Link to Authority: Cite and link to recognized studies, government data and academic papers. This signals that your content is well-researched and positions it within a trusted network of information.

Structured Data and Schema Markup is the Language of AI

If authority is the soul of your content, structured data (like Schema.org markup) is its central nervous system. It provides a machine-readable format that explicitly tells AI what your content is about, making it easier to parse, understand and cite.

Structured data, is a powerful tool for helping AI models understand the content and context of your web pages. By using schema to identify key elements of your content, such as author, publication date and data tables, you can make it easier for AI to process and extract information. This, in turn, increases the chances that your content will be used by ChatGPT and other AI chatbots to answer user queries.

The Data:

• Microsoft has officially confirmed that Bing uses Schema.org markup to help its AI models, including Copilot, understand page content. While Google has been less explicit, the behaviour of AI Overviews strongly suggests a similar reliance.

• A July 2025 report from Insightland notes that specific schema types are particularly useful. FAQPage, Question and Answer schemas align perfectly with the conversational nature of AI search. Similarly, HowTo and HowToStep schemas provide the clear, logical structure that LLMs need to generate step-by-step instructions.

• For e-commerce, schema for Product, Offer, Review and AggregateRating is critical. It allows ChatGPT and other AI chatbots to pull structured details like price, availability and user ratings directly into their synthesized answers.

GEO Strategy:

• Implement Comprehensive Schema: Go beyond basic Organization schema. Use specific, nested schemas like FAQPage, HowTo, Article (with author and publisher properties) and Product wherever they apply.

• Use JSON-LD: Implement structured data using JSON-LD, Google’s recommended format. It’s cleaner to manage and can be placed in the <head> of your HTML, separate from the body content.

• Validate for Perfection: Use tools like Google’s Rich Results Test and the Schema Markup Validator to ensure your implementation is error-free. Clean, validated schema is a powerful signal of a high-quality, well-maintained site.
