Header Tags Are Not Font Size Selectors
I've seen people use H1 tags because they wanted big bold text.
I've seen H3 tags before H2 tags because "it looked better."
I've seen pages with seven H1 tags.

Google uses header tags to understand your content's structure and hierarchy. Mess it up, and you're giving Google a scrambled roadmap.
The Hierarchy Rules
H1: One per page. It's your main topic. Include your primary keyword.
H2: Major sections. Think of these as chapter titles. Use 3-6 per post.
H3: Subsections within an H2. Supporting points.
H4-H6: Rarely needed, but use them if your content goes deeper.
The Order Matters
H1 -> H2 -> H3 -> H2 -> H3
Never skip levels. Never go H1 -> H3. That's like a book with chapters but no sections.
