A fundamental shift is underway in how buyers are discovering companies. Prospects no longer solely rely on Google to research vendors, compare products, or make purchasing decisions. They are increasingly turning to AI-powered platforms such as ChatGPT, Claude, and Perplexity to ask direct questions. The answers they receive help determine which companies make their shortlist and which remain entirely invisible.
This is the new visibility gap. Generative Engine Optimization (GEO) and its cousin, Answer Engine Optimization (AEO), refer to the practice of structuring your digital content so that AI models can discover, read, and recommend your company when users ask relevant questions. And it is widening every day.
When a prospect asks an AI model, “Who are the best providers of industrial equipment in my market?” The model builds its answer from web content, but not all web content. It prioritizes the structure of how authority is detected in HTML, the organization of content, and whether that information is accessible to automated systems. It rewards clear, specific claims that are backed by data and real numbers. It pulls from pages that answer questions directly, in plain language, with evidence and authority.
Companies may have extensive product catalogs, but if they are locked inside PDF documents, they become invisible to AI. Competitors may appear in every AI response, even if they have a smaller product range, simply because their content is structured properly.
After testing dozens of industry queries across various AI models, including Perplexity, Claude, ChatGPT, and other models, a remarkably consistent pattern emerges: AI models favor pages with short paragraphs, structured data such as FAQ sections and comparison tables, clear headings with specific claims, and content that satisfies Google’s EEAT framework of Experience, Expertise, Authoritativeness, and Trustworthiness.
One of the most significant and overlooked barriers to AI visibility is the widespread use of PDF documents to store product information. If your company stores rich specifications, detailed use cases, and pricing tables in PDF format, that content is effectively invisible to AI models, and none of it appears in AI-generated answers.
The same applies to content hidden behind login walls. AI models cannot access gated content. If your most detailed and valuable product information requires a user to fill out information before viewing it, AI will never read it, and your company will not appear in the answers your prospects receive.
In a 2025 McKinsey & Company survey, half of consumers reported using AI-powered search engines, and a majority said it’s the top digital source when making buying decisions (McKinsey & Company, 2025). Your buyers are already using AI to find vendors. The question is whether your company is showing up in their results.
In a recent workshop conducted for a major telecom client with over 50 participants, we mapped the company’s entire web presence against AI visibility metrics. The results were stark.
Competitors with objectively weaker products and smaller market share consistently appeared in AI-generated answers. The reason was not product quality or brand recognition. It was because of their content structure. The competitors had better HTML organization, more specific product specifications, no PDF-locked content, and no content difficult for AI engines to discover. This is a pattern that is not unique to the telecom sector.
GEO and AEO are areas where early action creates lasting advantage. The companies investing in AI visibility now will own AI-generated answers in their categories for years to come. Those who wait will be playing catch-up against the competitors who moved first.
Here are three steps you can take today to begin your GEO journey:
- Audit your current AI visibility. Ask three different AI agents about your product category and compare the results. This will give you an immediate picture of where you stand relative to your competitors.
- Convert your highest-value PDFs into structured HTML. Identify the PDF documents on your website that contain your most important product information, such as specifications, use cases, pricing tables, and comparison guides. Convert these into structured HTML pages with short paragraphs, specific numbers, and FAQ sections. Do not forget about specific technical files such as llms.txt, schema.org markup, and JSON-LD.
- Build schema markup and structured data into product pages. Adding structured data to your product pages tells AI systems exactly what your content contains and who it is for.
Optimizing for AI answers is a new frontier, but the underlying principle is familiar: Meet your buyers where they are. Today, they are increasingly asking AI platforms for guidance. The brands that structure their content to be discovered, read, and recommended by those platforms will hold a significant and durable competitive advantage.
