The SEO Rulebook Just Got Rewritten: ‘Write for The Human’ has a new twist
Understanding retrieval-augmented generation and what it means for content creators in 2025
While most marketers are still optimising for human search behavior, artificial intelligence systems are constantly refining how content gets discovered, processed, and served.
The fundamental assumptions we've built SEO strategies around, keyword density, human-readable URLs, content that flows naturally for human eyes, are becoming secondary to a new priority: making your content perfectly digestible for AI retrieval systems.
This isn't just another algorithmic update we need to adapt to. This is a complete paradigm shift in how information gets found and delivered, and some content creators don’t realise how dramatic the game has changed. The core principle of "write for humans" remains paramount, but the landscape of how content is consumed and processed has undeniably changed.
The rise of agentic AI scrapers and large language models (LLMs) means that your content isn't just being read by people; it's also being consumed, analyzed, and synthesised by machines. The key is not to abandon the "write for humans" rule, but to adapt it with a new layer of consideration, maintaining a human-first approach, but with custom structured clarity.
Your primary goal should always be to provide value to your human readers, using natural language to appeal to NLP algorithms like BERT and MUM, a clear and engaging tone, and a logical flow. Intense keyword stuffing to appeal to a machine will still likely lead to terrible UX, which Google's algorithms are designed to identify, and perhaps penalise.
Why AI-Powered Search Is Reading Your Content Completely Differently Than Humans Ever Did
When a human searches for information, they scan, skim, and contextually interpret content based on visual hierarchy and familiar patterns. They'll read your H1, glance at subheadings, and decide whether to invest time in your full article. It's an intuitive, somewhat chaotic process driven by personal experience and cognitive shortcuts.
AI systems, particularly those using Retrieval-Augmented Generation (RAG), approach your content with surgical precision. They're not scanning—they're parsing. They're not skimming—they're indexing semantic relationships. And crucially, they're not looking for content that flows well for human consumption; they're hunting for specific, structured information that directly answers queries.
Consider how ChatGPT with browsing mode, Claude with web access, or Perplexity processes your website. These systems aren't reading your carefully crafted introduction or appreciating your brand voice. They're extracting data points, identifying semantic connections, and chunking your content into retrievable segments that can serve as precise answers to user questions.
This creates an entirely new optimisation challenge: your content needs to satisfy both human readers who want engaging, flowing narratives and AI systems that want structured, semantically clear information chunks.
How Fragment IDs and Semantic Anchors Create Direct Pathways for RAG Systems
Here's where traditional SEO thinking breaks down completely. We've been taught that anchor links and fragment IDs are primarily navigation tools for human users. But in AI-powered retrieval systems, these HTML elements function as semantic bookmarks that can dramatically improve how your content gets selected and served.
When you create an anchor link like this:
<h3 id="llmseo">Large Language Model Search Engine Optimisation</h3>
LLMSEO represents the emerging practice of optimising content specifically for AI retrieval systems…
You're not just creating a page section that human users can jump to. You're creating a semantic handle that RAG systems can latch onto when they're processing your content for retrieval. If your page exists in their training data or crawled index, that #llmseo fragment acts as a direct bookmark, allowing the system to serve just that specific chunk of relevant content instead of attempting to condense your entire page.
The magic isn't in the hashtag symbol itself—it's in the conceptual alignment between your anchor ID, the surrounding content quality, and the types of queries users are asking AI systems. When someone asks ChatGPT "What is LLMSEO?" and your content exists in their accessible dataset, that semantic anchor creates a direct pathway from query to answer.
This is fundamentally different from traditional keyword research, where you're trying to guess what humans might type into a search box. Instead, you're creating structured content that AI systems can confidently reference when constructing responses.
What Facts Can Content Creators Research About Retrieval-Optimised Architecture Right Now
The shift toward retrieval-optimised content architecture requires rethinking how we structure information on our websites. Instead of writing purely for human reading patterns, we need to create dual-purpose content that serves both audiences effectively.
Here's what this looks like in practice. Traditional SEO might create a glossary section like this:
<h2>Digital Marketing Glossary</h2>
Understanding key terms in digital marketing…
API: Application Programming Interface
SEO: Search Engine OptimiSation
Retrieval-optimised architecture structures the same content with semantic anchors:
<h2>Digital Marketing Glossary</h2>
Application Programming Interface
An API enables different software applications to communicate with each other…
Search Engine optimisation
SEO involves optimising website content and structure to improve visibility…
This approach creates several digital marketing advantages simultaneously:
Semantic Linking Structure: By using descriptive anchor text that matches your glossary term IDs, you're creating clear semantic relationships that search engines and AI systems can easily parse and understand.
Internal Link Equity Distribution: These structured glossary links help distribute link authority throughout your content while keeping users engaged on your site longer, sending positive ranking signals.
Schema Enhancement Opportunities: This content structure sets you up perfectly for FAQ or HowTo schema markup, especially when your glossary terms explain processes or answer common questions.
Rich Results Potential: Search algorithms increasingly favor content that demonstrates clear expertise through well-structured terminology and definitions, improving your chances for featured snippets and knowledge panel inclusions.
Why Traditional Keyword Research Is Missing Critical AIO Opportunities
Traditional keyword research tools are designed around human search behavior—they analyze what people type into search boxes, how often they search for specific terms, and what competing pages rank for those queries. This approach worked brilliantly when humans were the primary consumers of search results.
But AI systems don't search the way humans do. When someone asks Claude "How does retrieval-augmented generation work?" they're not using the same language patterns they'd type into Google. They're asking natural language questions, often with more technical precision and contextual depth than typical search queries.
This creates a massive opportunity gap. While your competitors are writing about "RAG AI" or "retrieval augmented generation guide," you could be creating content anchored to the exact technical concepts and semantic relationships that AI systems are actually retrieving for: #entity-recognition, #knowledge-graph-integration, #semantic-search-alignment.
The real insight here is understanding that AI systems are searching for conceptual matches to construct answers, not necessarily matching the exact keywords users input. Your content needs to cover the semantic territory around a concept comprehensively, with clear structural markers that help retrieval systems understand what information you're providing.
How Current RAG Systems Actually Process and Retrieve Your Website Content
Understanding the technical mechanics of how RAG systems interact with web content reveals why traditional SEO approaches are becoming insufficient. When an AI system with web access processes your site, it's following a fundamentally different pathway than human visitors or traditional search crawlers.
First, the system identifies potentially relevant content based on semantic similarity to the user's query. This isn't keyword matching—it's conceptual alignment using embedding models that understand meaning and context. Your page about "customer relationship management software" might get retrieved for a query about "improving client communication workflows" even if those exact terms don't appear in your content.
Second, once your content is identified as potentially relevant, the system needs to extract the specific information that answers the user's question. This is where your content structure becomes critical. If your valuable insights are buried in long paragraphs without clear semantic markers, the system might struggle to extract and confidently cite your expertise.
Finally, the system evaluates whether the retrieved information is sufficiently authoritative and comprehensive to include in its response. Content with clear expertise signals, proper attribution, and structured presentation of information performs significantly better in this evaluation phase.
This process reveals why fragment IDs and semantic anchors are so powerful: they create explicit waypoints that help retrieval systems locate and extract exactly the information they need, rather than forcing them to parse and summarise larger content blocks.
Why Most SEO Professionals Are Completely Unprepared for This Algorithmic Evolution
The SEO industry has spent decades perfecting content marketing strategies based on one fundamental assumption: human users discovering content through search engines and then engaging with that content directly. Every ranking factor, every best practice, every tool in our arsenal was designed around this human-centric discovery model.
But AI-mediated content discovery breaks this model entirely. Users aren't necessarily clicking through to your website anymore—they're getting answers directly from AI systems that have processed and synthesised your content along with multiple other sources. Your beautifully optimised page might never receive a human visitor, even when your expertise directly contributes to AI responses.
This creates a professional identity crisis for SEO strategists. Are we optimising for visibility and traffic, or are we optimising for knowledge retrieval and attribution? These goals sometimes align, but they often require completely different strategic approaches.
Most SEO professionals are still focused on traditional metrics: keyword rankings, organic traffic, click-through rates. But these metrics become secondary when your content's primary value comes from being retrieved and referenced by AI systems, not from direct human engagement.
The professionals who will thrive in this new landscape are those who understand both traditional search optimisation and the emerging science of retrieval-augmented generation. They're building content strategies that serve multiple masters: human readers, traditional search algorithms, and AI retrieval systems.
Testing Retrieval-optimised Content Architecture in Live Client Projects Right Now
Theory is fascinating, but practical implementation is where real insights emerge. As I write this in August 2025, I'm actively testing retrieval-optimised content architecture across multiple client websites to understand which approaches deliver measurable results.
The testing methodology is straightforward: implement semantic anchor structures, fragment IDs, and retrieval-friendly content formatting on new website content, then monitor how that content performs across different AI systems. The goal isn't just to see if AI systems can find and reference the content—it's to understand whether this optimisation approach creates competitive advantages in AI-mediated discovery.
Early observations suggest that content structured with clear semantic anchors does indeed get referenced more frequently and accurately by AI systems. But the real question is whether this translates into business value: increased brand visibility, more qualified leads, better positioning as a subject matter expert.
What makes this particularly interesting is that implementing retrieval-optimised architecture doesn't harm traditional SEO performance. The semantic anchors, structured content, and comprehensive topic coverage that help AI systems also tend to improve human user experience and traditional search visibility. It's not a zero-sum optimisation challenge—it's additive.
The testing approach involves creating content that serves as both human-readable resources and AI-retrievable knowledge bases, then measuring performance across both channels. This dual-purpose strategy acknowledges that we're in a transitional period where both discovery methods remain important.
What Content Strategists Should Start Implementing Today to Stay Competitive Tomorrow
The window for early adoption advantages in AI-optimised content is closing rapidly. While most content creators are still debating whether AI-powered search will impact their strategy, forward-thinking strategists should be implementing retrieval-friendly architecture immediately.
Start with your highest-value content—the pages that demonstrate your deepest expertise and answer the most important questions in your field. Restructure these pages with semantic anchors that correspond to key concepts, technical terms, and frequently asked questions. Create internal linking structures that help both human users and AI systems navigate between related concepts on your site.
Develop glossary and definition sections that use fragment IDs matching the technical terminology in your industry. If you work in financial services, create anchors like #fiduciary-responsibility, #portfolio-diversification, and #risk-adjusted-returns. If you're in software development, structure content around #microservices-architecture, #continuous-integration, and #api-design-patterns.
Most importantly, start thinking about your content as a knowledge base that serves multiple consumers simultaneously. Your human readers need engaging narratives and clear explanations. Traditional search engines need keyword relevance and authority signals. AI retrieval systems need structured information with clear semantic markers and comprehensive topic coverage.
The strategic advantage goes to content creators who can satisfy all three audiences without compromising the effectiveness of any single approach. This requires more sophisticated content planning and implementation, but it also creates significantly more robust competitive positioning.

Consider both Agentic scrapers (good at finding and extracting specific pieces of information) with intelligently structuring your content clearly, you are producing accessible and engaging content for both humans and AI to find what they need. Headings and subheadings (H1, H2, H3, etc.):
Bulleted and numbered lists: These are easy for both to scan and digest.
Short, declarative sentences: While not a hard rule, simple, direct sentences are less ambiguous for both. Start paragraphs with a sentence that clearly states the main idea.
With Search Intent at the forefront of these methods, clear topic sentences help both humans skim-reading and an AI-appeal when they are scanning for a specific concept.
Map out your own Knowledge Graph with Entities, subjects and niche topics that answer highly specific search phrases. We avoid repeating a single keyword, think about the broader topic and its related family tree. For example, if you're writing about "sustainable gardening," you'd also want to include related terms like "composting," "organic soil," "water conservation," and specific plant names.
These small tasks 100% helps both humans and AI understand the depth and breadth of your content.
Questions Offer Important Answers for Agentic Scrapers
Write FAQ Pages that answer direct questions. Agentic scrapers and LLMs are often tasked with answering niche user questions. If your content directly and clearly answers common questions related to your topic, you're more likely to be a source for that information.
Using the FAQ format or create sections that address specific queries helps to showcase your depth of understand and drill down to the desired topic knowledge research. If you're providing a definition or a specific statistic, present it as a clear statement, not hidden within a long, rambling paragraph.
I like long sentences every now and again, so whilst I keep my section lengths varied, I choose the most impactful statements to be formatted as shortest sections - the best of both.
AI Overviews Sniff Success with Short, Succinct, Summaries.
This is why a concise summary at the beginning or a footer at the end of your article helps both humans and AI quickly grasp the main takeaways.
This is particularly useful for AI, which might use this summary to generate a quick response.
