The Encyclopedia Mistake in Subheadings: Turning H3s into Micro-Action Prompts
For years, I filled H3 subheadings with noun phrases like 'The Importance of Image Optimization'—piling on information without telling readers what to actually do.
In my early years at the writing desk, I used to measure the depth of my technical guides by the sheer weight of their subheadings. I assumed that the more academic, the more encyclopedic my breakdown of a topic was, the more authoritative I would appear. I would write subheads like "The Importance of Image Optimization", "The Keyword Research Process", or "Designing Meta Descriptions", and pack everything beneath them with theoretical exposition. Time-on-page metrics were decent; I would glance at the analytics dashboard with pride. But one day I faced the bitter truth: readers weren't patiently reading these pieces—they were merely scanning them, and worse yet, leaving the page without implementing a single one of the detailed steps I laid out. Because my subheadings weren't road signs; they were library index cards.
