Here is why this is critical: ### 1. Navigation and understanding for users Headings break text into logical blocks. People scan a page with their eyes and immediately see where things are. ### 2. Screen readers and accessibility (a11y) For blind users, headings are the primary way to move around a page. A screen reader can read out just the headings, and the user quickly understands the structure. ### 3. SEO and indexing Search engines use headings to understand what a section is about and which part is more important. `<h1>` is a key signal: "this is the page's main topic". Mistakes like several `<h1>` tags or skipped levels prevent the bot from understanding the meaning. ### 4. Semantics and code maintainability When headings are used for their purpose, the document is easier to read, edit, and parse. Unlike `<div class="title">`, `<h2>` is immediately clear to both a human and a machine. ### 5. Extended browser and plugin features Many extensions, assistants, and development tools can build a page's "table of contents" precisely from its headings. **Conclusion:** Correct `<h1>`-`<h6>` hierarchy is like a building's frame. Without it, a page turns into a pile of text that can be neither read nor analyzed.For the reviewerNote to the moderator (optional)Visible only to the moderator. Helps review go faster.
