Headings (H1-H6 tags) are an important part of good blog writing and SEO. Used properly, headings organize your content and help search engines understand the topic and structure of your posts.

The Benefits of Using Headings

Headings provide three key benefits:

1. Improve Readability

Headings break up blocks of text into easy-to-scan sections, improving readability. Readers can grasp the main points at a glance.

2. Establish Hierarchy

Heading tags indicate the hierarchy of information. H1 is the main title, H2 headings cover key sections, H3 for subsections, etc. This creates logical structure.

3. Boost SEO

Headings signal to search engines the focus and organization of the content. Optimized headings improve crawlability and rankings.

Best Practices for Each Type of Heading Tag

Follow these best practices when structuring content with headings:

1. Where to use H1 Headings - The Main Page Title

The H1 should concisely summarize the overall focus of the post. Generally keep it under 60 characters. Have only one H1 per page.

2. Where to put H2 Headings - Major Sections

Use H2 headings to divide your post into logical sections. These form the main subtopics under your title. Use 2-4 H2s per post.

3. Where to place H3 Headings - Subsections

H3s break the H2 sections into smaller subsections for additional hierarchy. Use 2-4 H3s per H2.

Best Practices for Using H4, H5 and H6 Tags

H4-H6 Headings - Deeper Breakdowns

Reserve H4-H6 headings for niche breakdowns and lower-level sections as needed. Use these sparingly.


By following proper heading tag usage, you can create more optimized, readable content.

When to Use H4 Headings

Use H4 tags for subsections under an H3 heading. They create another layer in the hierarchy.


For example:


H4 Subsection Under H3


This H4 segment is nested under a higher H3 section.


Effective Use of H5 Tags

H5 headings denote sub-content under an H4 section. Use them for things like:


H5 Example
  1. Numbered lists


  • Bullet points

H6 For Granular Breakdowns

Reserve H6 for very granular breakdowns of content, like:


When H6 is Helpful
  • Detailed processes
  • Step-by-step instructions
  • Highly specific topics


H4-H6 headings help organize deep, thorough content. Use them strategically when H3 sections need further segmentation.
