The way we consume web content has changed dramatically in recent years. Users arrive at websites through many different devices and search experiences, from classic Google searches to AI-powered answer engines and voice assistants. Now, sites need to serve not only human visitors with shrinking attention spans, but also AI models that read, summarize, and extract answers from your pages. Both audiences have unique needs but the solution is surprisingly universal: clear structure, logical flow, and accessible formatting.
This blog covers current best practices for making your website readable for both AI systems and people. We’ll explore how AI models (like ChatGPT and Google’s AI Overviews) understand web pages, how humans scan content, and which structural choices help you rank, get cited, and keep visitors engaged. We’ll also answer common questions about headings, content blocks, navigation, and readability to help you optimize your site for the future of search.
How AI Interprets Web Content
Beyond Crawling: How LLMs Parse Pages
AI systems, especially large language models (LLMs) such as GPT-4, Gemini, or Claude, don’t browse your page like traditional web crawlers. Instead, they ingest and tokenize raw text, analyze relationships and semantic meaning, and break content into blocks based on structure. Rather than relying solely on HTML tags or schema markup, LLMs pay special attention to headings, logical order, and concise summaries.
Key Elements AI Looks For:
• Logical heading hierarchies (H1, H2, H3…): Clear, nested structure helps LLMs map out the page and group related ideas.
• Short, self-contained paragraphs: One idea per paragraph reduces confusion when AI extracts content for summaries or direct answers.
• Structured formats lists, tables, FAQs: Lists and tables are easy for both AIs and users to scan and for bots to extract answer snippets from.
• Front-loaded key information: Brief definitions or answers at the top of the page increase likelihood of AI selection for snippets and summaries.
• Semantic cues: Phrases like “step 1”, “key takeaway”, “frequently asked questions” signal structure both to LLMs and to readers.
AI models are designed to surface the clearest, most easily parsed answers. If your content is well-formatted and directly addresses user queries, it’s more likely to be referenced or shown as a featured answer.
The Role of Schema
Structured data (e.g., Schema.org markup, JSON-LD) remains valuable especially for ranking in rich snippets but is not a substitute for well-structured writing. If your content is confusing, AI can miss key points even with perfect schema. Conversely, strong page architecture often wins inclusion in AI-driven summaries regardless of markup.
To enhance your structure and visibility in AI content creation and AI marketing services workflows, schema and clear writing together are key.
Human Scanning Patterns: How People Really Read Websites
Humans rarely read web pages linearly or word for word. Eye-tracking studies show persistent patterns:
• Scanning and Skimming: Almost 80% of users scan rather than read; only 16% read every word.
• F-shaped pattern: On text-heavy pages, users read across the top, then across subheadings, then scan down the left edge. Critical info near the top left is most seen.
• Z-shaped pattern: On visually focused or landing pages, users read across the top, diagonally to the lower left, then across the bottom covering core elements.
• Layer-cake, spotted, and commitment patterns: Some users bounce between headings (“layer-cake”), spot-highlight keywords/images, or read fully if highly motivated to learn.
Implications for Web Design
• Use headings, bullets, visuals, and summaries to break up text and guide the scanning eye.
• Place crucial info and calls to action early and along the scan path. Don’t make visitors search for what matters.
• Highlight key words and phrases in bold where needed, but sparingly (to avoid turning the page into a wall of emphasis).
• Provide logical navigation and clear CTAs so people can quickly move through the site.
These conventions are not only about aesthetics—they are proven to improve engagement, comprehension, and conversion rates. For more design-oriented approaches, see Product Development and Product Optimisation strategies that enhance user interaction.
Why Proper Structure Matters for Both AI and Humans
Accessibility
Using logical headings, short paragraphs, and outlined lists isn’t just good for SEO. It improves accessibility for everyone including screen reader users and people with cognitive disabilities. Proper heading structure lets screen readers generate an outline enabling users to jump straight to the section they need.
SEO and AI Visibility
Google, Bing, and AI Overviews now look for “direct answers,” not just keyword density. Their algorithms favor content that’s:
• Organized into thematic blocks (with clear headings)
• Easy to extract snippets from (bullets, tables, FAQs)
• Written in plain language with minimal redundant or off-topic material
Sites that follow these principles tend to rank higher and are more likely to be quoted in AI-generated summaries, featured snippets, or answer panels. This aligns closely with SXO and Search Engine Optimisation best practices.
Headings: How to Structure for SEO, AI, and Accessibility
Heading Levels: H1–H6 Hierarchy
Every web page should use a single H1 for its main title, breaking down into H2s, H3s, etc., as the structure requires:
| Heading Level | Role | Typical Use |
| H1 | Page/document main title (one per page) | “How to Improve Website Readability” |
| H2 | Main section titles | “Why Structure Matters” |
| H3 | Subsections under H2 | “Screen Readers and Accessibility” |
| H4–H6 | Further sub-subsections (rarely needed for most sites) |
Best practices:
• Use only one H1 per page, don’t repeat or skip levels.
• Write clear, descriptive headings (not just for style, but for meaning) avoid choosing heading tags based on how text looks.
• Use H2s to outline primary topics (usually what a reader would expect in a table of contents).
• Avoid jumping from H2 to H4 (don’t skip H3 if you need a sub-section).
• Test your outline: if you hid the rest of the page, would just the headings tell the story? If yes, you have a strong structure.
Headings are essential for AI (to parse content blocks), for SEO relevance (categorizing topics), for user scanning, and for accessibility (screen readers).
Content Blocks: Designing for Easy Consumption
Divide Content Into Meaningful Sections
• One main idea per paragraph or block. Avoid bloated paragraphs that bury key points.
• Bullets and numbered lists make steps, comparisons, or collections of info scannable (and more likely for AI or humans to pull out as answers).
• Visuals (images, tables) give context, break up text, and foster understanding. Always use descriptive alt text for accessibility and SEO.
• Whitespace and short sections lessen visual fatigue and cognitive load (making giant “walls of text” a thing of the past).
Examples of Effective Content Block Use
• A “how-to” page starts with a summary, lists required tools as a bullet list, and uses numbered steps (with screenshots) for a process: easier for both AI and people to parse and cite.
• FAQ pages use short, direct Q&A pairs, often with collapsible sections for optimal readability and mobile performance.
Logical Content Flow: Guiding Users and AI Alike
What Is Logical Flow?
• Introduce the topic (context, value, what problem you’ll solve).
• Break the information into progressively detailed, self-contained sections (from general to specific).
• Use transition sentences at section boundaries to clarify relationships.
• End sections with a summary, next steps, or a clear call to action.
Front-load What Matters
Put your most important info, direct answers, and definitions at the top of each page or block. This benefits:
• Users, who want quick solutions
• AIs, who prioritize top content for summaries and voice answers (AEO – answer engine optimization)
Coherent Internal Linking
Smart website flow includes links to related content, guides, or next actions (whether for purchasing, subscribing, or learning more). This:
• Keeps users moving through your funnel
• Helps AI connect your topical authority, passing SEO value between pages
SEO and AEO: Making Content Findable for Search and AI
SEO Readability Checklist (for Both Humans and AI)
• Write for clarity and brevity: Short sentences, known vocabulary, minimal jargon.
• Strong, keyword-rich headings and subheadings: Embed user queries as headings to align with search and AI expectations.
• First-sentence answers: Address user queries immediately (LLMs are designed to extract these).
• Consistent formatting: Logical heading levels, short paragraphs, lists, and tables.
• Accessibility and alt text: Always add descriptive text for images.
• Internal linking: Connect related posts, guides, or services.
• User testing and readability auditing: Use Flesch-Kincaid scores or tools like Hemingway or Yoast to ensure at least an 8th–9th grade level, unless technical detail requires more. Aim for Reading Ease scores of 60–80 for general audiences.
These steps are essential for achieving Search Engine Optimisation and Answer Engine Optimisation (AEO) success.
Common FAQs on Site Readability
How many H1s should my page have?
Just one. Multiple H1s confuse both search engines and screen readers. Use H2s for main sections, H3s for subsections, and descend only as deeply as needed.
Can I use heading tags just for style?
No. Use headings to define the content’s structure, not for visual effect. Use CSS to style appearance; heading tags communicate meaning to AI and accessibility tools.
What’s the “F-pattern” and why does it matter?
People typically scan left-to-right across the top (navigation/menu, main headline), then a bit lower (subheadings), then down the left edge. This means you should place crucial content like calls to action, keywords, or definitions where people and bots look first.
Should I use bullets and tables?
Yes, as much as practical. They make content easy to scan, help break up information, and allow both AIs and people to find answers quickly.
How do I optimize for AI and answer engines (AEO)?
• Use question-and-answer blocks and direct definitions.
• Place explicit answers near the start of content sections.
• Structure your content so headings match common search queries (e.g., “How do I improve website readability?” as an H2).
• Use schema or FAQ markup for how-to guides when relevant, but focus first on clear page structure.
Do short paragraphs really matter?
Yes. Short paragraphs (<4 lines) reduce cognitive load and make both humans and LLMs more likely to accurately understand each point.
How should I handle mobile readability?
• Responsive layouts are essential.
• Use adequate font size (at least 16px body text on mobile).
• Keep line lengths short (40–60 characters per line).
• Provide whitespace and tap-friendly elements.
• Avoid popups, auto-play videos, or anything that obscures content.
Markdown Formatting Tips for Web Readability
Many CMSs and knowledge bases use Markdown for editing:
• Use proper heading syntax (, , …).
• Separate content sections with blank lines.
• Use bulleted and numbered lists for enumeration and steps.
• Never skip heading levels.
• Use blockquotes to highlight callouts or important info.
• Keep line length under 80–100 characters for version control and easier scanning.
This results in portable, easily transformed content for websites, documentation, and even AI tools.
Real-World Examples and Case Studies
High-Visibility FAQ Hubs
Sites like Wikipedia, Google Support, and Amazon structure their FAQ pages as navigable hubs with questions as H2 headings and clear, concise answers. This approach caters to both human scanning and AI-driven answer extraction.
Product Guides and Tutorials
Leading brands position step-by-step instructions using heading hierarchies, bullets, and “how-to” schemas, increasing their eligibility for featured snippets and answer rankings.
Blog Posts with Clear Outlines
SEO-focused blogs perform best when formatted with descriptive H1s, H2s for topic divisions, and frequent short list blocks.
Conclusion: Structure Is Your Superpower
Websites that prioritize clarity, logical flow, and accessible formatting consistently perform better in both human and AI-driven discovery.
