Optimizing Heading Structures for SEO in the Age of AI Crawlers: A 2025 Perspective

In the rapidly evolving landscape of web development and search engine optimization (SEO), staying current with best practices is essential—particularly as artificial intelligence (AI) and large language models (LLMs) become more sophisticated in how they interpret website content. For front-end designers collaborating with SEO professionals, understanding how to structure headings effectively can significantly impact the discoverability and ranking of your site.

The Role of Headings in Modern SEO
