Chunking and SEO: A method that sparks debate among SEO specialists

With the accelerated evolution of artificial intelligence and the increasing complexity of search algorithms, the method of chunking, or content cutting, is becoming a hot topic in the SEO world in 2025. At first glance, it’s a technique aimed at structuring articles into short, coherent passages to optimize their comprehension by search engines and their visibility in results. But behind this apparent simplicity lies a heated debate. Some experts consider it a true revolution, a way to boost SEO and readability. Others see it as a simple scraping/la-polyvalence-du-scraping-un-outil-mille-possibilites/">marketing gimmick, a mirage that would not change much in the real practice of SEO. The discussion is not limited to technique: it reveals two opposing visions, one that advocates adaptation to AI, and the other that emphasizes the very essence of good content: quality and human impact. Let’s start with a solid foundation to understand what’s behind the chunking hype in 2025.

Why “ChunkSEO” has become essential in modern SEO strategy

For several years now, the lure of simplified SEO using techniques like “OptimBlock” or “SEOChunking” has regularly taken center stage. The key is to divide long content into fragments, or chunks, of 150 to 300 words, easily digestible by artificial intelligence systems and also by human readers. Why such enthusiasm? Because in 2025, the ability of search engines and AI assistants to analyze an entire text effortlessly is a reality. The need for precise chunking then becomes strategic. The method is also recommended by most SEO tools, such as the famous SEO Chunking Pro, which emphasizes the importance of a “RefBlock” well-structured to “go beyond traditional metrics.” The practice of SEO Fragment promotes relevance, clarity, and, above all, makes it easier for search engines to find key information. A recent study shows that segmented content increases
SERP visibility by 27% to 41% using RAG (Retrieval-Augmented Generation) systems.Examples abound: e-commerce sites, specialized blogs, and even news portals now rely on the SegmentMethod to optimize their impact. The Limits of Chunking: When the Technique Becomes a Mirage Despite its apparent success, SEOPartition has attracted harsh criticism. The first comes from skeptics, who see
SEOBlock as a mere facade. According to them, chunking is primarily a marketing construct, a waste of words to mask the absence of truly relevant content. Nikki Pilkington, an English-speaking SEO expert, is blunt: “What GEO experts call chunking is simply a revival of the old principle of clarity: precise titles, concentrated paragraphs, one idea per section.” For her, the real challenge lies not in segmentation, but in the quality of the content, and above all, in mastering

to cope with the diversity of AI models. Moreover, Despina Gavoyannis adds: “The ‘chunk optimization’ technique is a dead end. It all depends on the model’s analysis strategies, which vary depending on the platform: ChatGPT, Bing, Perplexity… Each one chunks according to its own rules.” Furthermore, Dan Petrovic points out that “Automatic Chunks are integrated into each browser or engine, based on HTML structure and semantics, without human intervention.” In other words, SEOChunks becomes a variable beyond the creator’s control, a sort of technical parameter that cannot truly be controlled. This majority of the SEO community therefore insists on the importance of remaining faithful to the essence of good content: clear writing, logical organization, and a focus on the audience rather than on technical tricks. Otherwise, the risk is of building an artificial, ineffective, or even counterproductive

Despite these criticisms, some take the logic even further. According to them, SEOChunkingPro is not a passing fad, but an essential step in addressing the transformations to come. Philippe Yonnet, a recognized expert, insists: “The SegmentMethod allows you to produce short, coherent passages that can be understood independently.” »
In 2025, the limitations of transformers are well understood: they analyze text in “successive windows” of 150 to 350 tokens. Poorly segmented content will then be misinterpreted or ignored. The best strategy is to segment intelligently, taking meaning and context into account. Aishwarya Srinivasan, a specialist in natural language processing, explains: “The Semantic-Based Chunking technique consists of chunking based on changes in meaning, rather than raw length.” She adds: “Even with Modality-Aware Chunking—which takes images, tables, and other media into account—we maximize the relevance and accuracy of the generated responses.”
