In content writing, crafting engaging and well-structured content is only half the battle. The real challenge lies in making your work visually appealing and easy to navigate, ensuring readers can quickly locate the information they seek. This is where headings and subheadings become crucial – they dramatically increase your content’s impact by providing structure and improving readability. In this comprehensive guide, we’ll explore everything from heading hierarchy and HTML implementation to accessibility considerations and format-specific requirements.
What are Headings and Subheadings?
Headings are titles or phrases that break down a document or article into organized sections or topics. They provide structure by dividing content according to subject matter while serving as navigational cues for readers looking for specific information.
Subheadings are smaller divisions within those larger sections marked by headings. They offer deeper segmentation of the material, making it easier for readers to quickly skim through content without reading every word when seeking specific answers.
Together, headings and subheadings function as signposts throughout your written work, guiding users toward particular points of interest within dense text. Think of them as a content roadmap – headings are main routes, while subheadings are the specific streets and addresses helping readers reach their exact destination.
Visual Example of Heading Hierarchy:
H1: Main Article Title (Used once per page) H2: Major Section Topic H3: Subsection Within Major Topic H4: Further Division of Subsection H5: Specific Point Within Subsection H6: Detailed Element (Rarely used)
Why are Headings and Subheadings Important?
Headings and subheadings are crucial in enhancing the readability and organization of written content. They serve multiple purposes, primarily guiding the reader through your work. Some key reasons explaining the importance of headings and subheadings are:
Structuring Your Content
Incorporating headers and subheaders facilitates structuring your article into logical sections, making it easy for readers to follow your line of thought. By breaking down your piece into smaller segments, you ensure that the audience clearly understands each aspect without getting overwhelmed.
Well-structured content with clear heading hierarchies is like providing a roadmap for your users. When visitors can easily navigate your content, they’re more likely to stay longer and fully absorb your message.
Enhancing Readability
Including headings and subheadings improve readability by clearly signaling transitions between topics, thus helping readers navigate smoothly through the content. Furthermore, they aid in maintaining interest as well-formatted articles with properly separated sections create visually appealing work that encourages continued reading.
Boosting SEO (Search Engine Optimization)
Including headings and subheadings improves readability by clearly signaling transitions between topics, helping readers navigate smoothly through content. Recent data shows that the average time on site for a top 10 search result is 3 minutes and 10 seconds, with well-structured content playing a key role in keeping readers engaged. This structured approach creates visually appealing work that encourages continued reading.
Boosting SEO (Search Engine Optimization)
From an online perspective, using headings and subheadings significantly contributes to your article’s search engine optimization (SEO). Search engines prioritize pages with well-structured content, employing informative headers containing relevant keywords.
According to recent Ahrefs data, a staggering 59.5% of websites are missing H1 tags, weakening their on-page SEO structure. Additionally, when Google ignores the title tag, it uses the H1 tag 50.76% of the time instead, further emphasizing the importance of optimized heading structures.
Supporting Accessibility
Properly structured headings are essential for users of assistive technologies like screen readers. When HTML heading tags are correctly implemented, screen readers can navigate through content effectively, allowing users to jump between sections and understand the document’s structure. This significantly improves the user experience for people with visual impairments and fulfills WCAG 2.1 accessibility requirements.
Heading structure is one of the first things I check when evaluating a site’s accessibility. Proper H1-H6 implementation creates a semantic outline that allows screen reader users to effectively navigate content. Otherweise, that’s impossible with visually-styled headings that lack proper HTML markup.
Aiding Information Retention
Headings serve as visual cues that assist readers in processing information swiftly while staying focused on critical points in your text. Additionally, the appropriate use of headers aids reader retention; when people can quickly access specific sections containing pertinent details within an article or blog post, they will be more likely to remember those details later.
Catering to Skimmers
Many individuals skim through content instead of thoroughly reading it word-for-word. Properly formatted headings emphasize vital concepts discussed throughout any piece enabling skimmers to grasp the main ideas without reading every paragraph. This is particularly important given that domains ranking in the top 3 spots have an average bounce rate of 49%, highlighting the need to capture and retain reader attention quickly.
Technical Implementation of Headings in HTML
Understanding the correct HTML implementation of headings is crucial for proper SEO, accessibility, and document structure. Let’s explore how to correctly implement headings in your web content.
HTML Heading Tags (H1-H6)
HTML provides six levels of heading tags, from <h1> through <h6>. These tags help establish a clear hierarchy of information:
<h1>This is the Main Page Title</h1> <h2>Major Section Heading</h2> <h3>Subsection Heading</h3> <h4>Further Division</h4> <h5>Specific Point</h5> <h6>Detailed Element</h6>
Each tag should be used in order, without skipping levels (e.g., don’t jump from an H2 to an H4 without using an H3 in between), as this maintains a logical document outline and supports accessibility.
Common Implementation Mistakes to Avoid
Using multiple H1 tags: Each page should have only one H1 tag, typically for the main page title.
Skipping heading levels: Always maintain a proper hierarchy without jumping levels.
Styling text to look like headings: Using CSS to make regular text look like headings instead of using proper heading tags confuses screen readers and search engines.
Using headings purely for styling: Heading tags should indicate structure and content hierarchy, not just make text bigger or bolder.
Inconsistent heading structure across pages: Maintain a consistent approach to headings across your entire website.
Example of Proper vs. Improper Heading Structure
Improper Heading Structure:
<h1>Company Blog</h1> <h3>Recent Updates</h3> <!– Skipped H2 –> <h6>New Product Launch</h6> <!– Jumped from H3 to H6 –> <p style=”font-size: 20px; font-weight: bold;”>Customer Reviews</p> <!– Styled to look like a heading –>
Proper heading structure is essential for making content accessible to all users, particularly those who rely on assistive technologies. According to WCAG 2.1 guidelines, well-structured headings are a fundamental component of accessible web content.
How Screen Readers Use Headings
Screen reader users often navigate content by jumping between headings using keyboard shortcuts. This makes headings crucial for these users to understand the content structure and find relevant information quickly. Without proper heading structure, screen reader users might need to listen to the entire content to find what they’re looking for.
“For screen reader users, headings are the primary way to navigate content. When I’m using JAWS or NVDA, the first thing I do is pull up the headings list to understand the document structure and jump to sections that interest me. Missing or improper headings make this navigation impossible.”
WCAG 2.1 Requirements for Headings
WCAG 2.1 includes several specific requirements for heading implementation:
Use semantic markup for headings (H1-H6) to convey document structure
Headings must accurately describe the topic or purpose of their content
Organize headings in a logical hierarchy, without skipping levels
Section headings should be used to organize content when appropriate (Level AAA)
To maintain WCAG compliance, ensure your headings are:
Descriptive of the content they introduce
Properly nested in a logical hierarchy
Used for structuring content, not just visual styling
Concise and free from “marketing language” that doesn’t clearly indicate content
Common Accessibility Violations Related to Headings
Some frequent accessibility issues related to headings include:
Using visual formatting (bold text) instead of proper heading tags
Skipping heading levels, disrupting the logical hierarchy
Non-descriptive headings that don’t clearly convey content
Lack of headings altogether
Improper use of H1 tags (multiple H1s or no H1)

Factors to Consider When Creating Headings
Creating successful headings involves much more than simply identifying topics; it requires careful consideration of several factors since they function as roadmaps for your readers’ journey through your piece.
Understandability
The primary role of any header is to improve your content’s readability by breaking it down into digestible parts. Prioritize clarity above all else – headings should immediately communicate what the following section contains.
Relevance
Each heading must directly correlate with its associated text block. If users click on a header expecting specific information, ensure that’s precisely what they get. Misleading headings lead to poor user experience and increased bounce rates.
Brevity
Keep headlines concise – short enough to catch attention but long enough to encapsulate relevance. Aim for 5-8 words when possible, focusing on conveying meaning rather than being clever or cryptic.
Consistency
Stick rigorously to one style throughout the article; varying formats might confuse readers about the text hierarchy. This applies to formatting, capitalization, and grammatical structure.
SEO-consciousness
Incorporate keywords naturally into headers for SEO ranking benefits (but not at the cost of undermining reader comfort). According to Ahrefs featured snippets study, 99.58% of featured snippets come from pages already ranking on the first page, and proper heading structure with relevant keywords can significantly increase your chances of earning these valuable SERP features.
I’ve consistently seen improvements in organic traffic when properly optimizing heading tags with relevant keywords. However, it’s essential to maintain natural language patterns, Google is sophisticated enough to understand semantic relationships without keyword stuffing.
Types of Headings for Different Content Formats
Heading structures differ significantly across content types, with each serving a unique purpose in organizing information and optimizing for search engines. Let’s explore how heading structures compare for blog posts, landing pages, and e-commerce product pages.
Blog Posts
Blog posts typically have the most complex heading structure, using H1 through H3 or H4 tags.
HTML Implementation:
One H1 tag for the blog post title
H2 tags for main sections
H3 and H4 tags for subsections
Optimal Heading Depth:
H1 for title
H2 for main sections
H3 for subsections
H4 for deeper subsections (if needed)
Keyword Placement:
Include primary keyword in H1
Use related keywords and variations in H2 and H3 tags
Incorporate long-tail keywords in lower-level headings
Landing Pages
Landing pages have a simpler structure, focusing on conveying key information quickly.
HTML Implementation:
One H1 tag for the main headline
H2 tags for key benefits or features
H3 tags sparingly for additional details
Optimal Heading Depth:
H1 for main headline
H2 for key sections
H3 for subsections (if necessary)
Keyword Placement:
Use action-oriented language in H2 tags
Incorporate benefits and unique selling points in headings
Focus on conversion-oriented language
E-commerce Product Pages
Product pages have a focused structure emphasizing product details and benefits.
HTML Implementation:
One H1 tag for the product name
H2 tags for key product features or sections
H3 tags for additional details or specifications

H1 for product name
H2 for main product sections (description, features, specs)
H3 for subsections within product details
Keyword Placement:
Include product name and primary keyword in H1
Use category or type keywords in H2 tags
Incorporate specific feature keywords in H3 tags
Best Practices for Writing Effective Headings and Subheadings
Learning the art of crafting riveting headings and subheadings can vastly improve your content’s readability, navigation, and SEO performance. Here are best practices to help you master this skill.
1. Capturing Reader Attention with Compelling Subheadings
The true power of a captivating subheading lies in its ability to draw readers into the heart of your content. Compelling subheadings serve as mini headlines – they should be engaging, informative, and establish an intriguing promise for what’s yet to come. In digital platforms where users scan through pages, persuasive subheadings ensure better user engagement rates by installing intrigue into readers’ minds.
While catchy titles might attract quick attention, refrain from producing deceptive clickbait that may mislead users about what they’re clicking into – providing disillusionment might cost you credibility.
2. Breaking Up Text and Improving Readability
Chunking down intimidating walls of text by strategically placing subheaders drastically improves readability. According to Semrush Ranking Factors Study, domains ranking in the top 3 spots have an average bounce rate of 49%, highlighting the importance of making content easily digestible. This improvement occurs because readers can:
Rest their eyes between content blocks
Better understand the content’s structure
Find specific information more easily
Resume reading from where they left off
3. Formatting and Styling for Visual Hierarchy
Proper formatting is non-negotiable when aiming to amplify readability. Headers should visually stand out from body text through:
Heading Style Comparison Table:
Element
Size
Weight
Color
Spacing
H1
Largest
Boldest
May use distinct color
Most space above/below
H2
Large
Bold
Usually same as H1
Significant spacing
H3
Medium
Bold or semi-bold
Usually same as body
Moderate spacing
H4-H6
Small-medium
Various weights
May match body text
Less spacing
This visual hierarchy leads readers smoothly through your content’s storyline and structural organization.
4. Incorporating Keywords for SEO
Incorporating keywords strategically into your headings is crucial for SEO. According to Semrush’s ranking factors study, text relevance is the most important Google ranking factor today, and heading structure plays a key role in establishing content relevance.
Best practices include:
Placing primary keywords near the beginning of headings when possible
Using synonyms and related terms in subheadings
Ensuring the heading accurately represents the content that follows
Create continuity by maintaining consistency across all headings within an article. This involves:
Using uniform capitalization (either title case or sentence case)
Maintaining consistent tense and grammatical structure
Following parallel construction patterns
Using similar phrasing approaches for similar content types
This consistency helps readers understand the relationship between different content sections and reinforces the document’s structural integrity.
Examples of Effective Headings and Subheadings: Before and After
To illustrate the principles of effective heading creation, let’s look at some before and after examples that demonstrate how to transform weak headings into strong ones.
Example 1: Blog Post Headings
Before:
Things You Can Do Some Information About SEO More Stuff Final Thoughts
The “after” example provides clear, specific information about what each section contains, incorporates keywords naturally, and follows a consistent structure.
Example 2: E-commerce Product Page
Before:
Description Details More Information
After:
Product Features and Benefits Technical Specifications and Dimensions Customer Reviews and Satisfaction Ratings
The revised headings give shoppers specific information about what they’ll find in each section, making it easier to locate the details they need to make a purchase decision.
Example 3: Academic Paper Headings
Before:
Introduction Literature Methods Results Discussion
After:
Introduction: Research Objectives and Significance Literature Review: Current Perspectives on Climate Adaptation Research Methodology and Data Collection Procedures Results: Statistical Analysis of Climate Intervention Effects Discussion: Implications for Environmental Policy Development
The improved headings provide specific context about each section’s content while maintaining academic formatting requirements.
Steps to Create a Proper Outline with Headings
Creating a clear and well-structured outline is essential for organizing your thoughts, ensuring the logical flow of ideas, and effectively guiding readers. Here’s a streamlined process for crafting an effective outline using headings:
1. Identify Your Main Topics
Start by brainstorming the core concepts you want to discuss in your article. These will form the basis for your primary headings (H2 tags in most web content). Ensure these main topics:
Cover the subject comprehensively
Flow logically from one to the next
Address your audience’s primary questions and needs
2. Create Logical Hierarchy
Once you have determined the main topics, group related ideas under these higher-level headings. For each subtopic, create subheadings that align with lower-level categories:
Use H2 headings for main sections
Use H3 headings for subsections within those main sections
Use H4 headings for further divisions when necessary
Maintain consistent depth across similar content types
3. Apply Consistent Formatting and Structure
To distinguish between different heading levels quickly and easily, maintain consistency in their formatting style and structure:
Use parallel construction for headings of the same level
Maintain consistent grammatical structure (all questions, all statements, all phrases, etc.)
Keep similar sections at the same heading level throughout your document
4. Review for Comprehensiveness and Flow
As you progress through your outline, regularly review the overall coherence of your heading choices:
Check that each main section (H2) covers a distinct aspect of your topic
Ensure subheadings (H3, H4) provide adequate coverage of their parent heading
Verify that the outline flows logically from introduction to conclusion
Confirm that no important subtopics are missing
5. Test Your Outline’s Effectiveness
Before finalizing your outline, test whether it effectively serves your purpose:
Read only the headings in sequence – does the narrative make sense?
Ask whether someone unfamiliar with the topic could understand the content structure
Check if the outline addresses the primary questions your audience might have
Verify that headings promise content that the sections will actually deliver
A well-structured outline serves as both a writing guide and a navigational aid for readers, ensuring your content is organized, comprehensive, and easy to follow.
Using Headings and Subheadings for SEO Optimization
The strategic usage of headings plays a crucial role in structuring your text and maximizing the visibility of your content on search engines. Here’s how to enhance your article’s readability and SEO performance through savvy heading selection.
Incorporating Keywords in Headings for Search Engine Visibility
Search engines like Google place higher weightage on terms within headings. This priority given to header text helps algorithms determine what your page is about, thus indexing it more accurately. Recent data shows that when Google ignores the title tag, it uses the H1 tag 50.76% of the time instead, highlighting the importance of optimizing heading tags.
When adding keywords to headings, ensure they are relevant to the content that follows them. Remember that stuffing irrelevant terms into your headings will confuse both readers and search engines.
Best practices include:
Use long-tail keyword phrases instead of single words; they tend to be less competitive and more specific
Utilize variant synonyms or related concepts rather than repeating the same phrase multiple times
Maintain a natural flow – don’t force keywords unnaturally
Prioritize inclusion in H1 and H2 headings where appropriate
Brodie Clark, SEO consultant and Google Search specialist, explains: “I’ve consistently seen pages with clear, question-based H2 and H3 tags win featured snippets more frequently. The key is structuring your content with headings that match common search queries, then providing concise, direct answers immediately below those headings.”
Use question-based H2 or H3 headings that match common search queries
Follow the heading immediately with a concise, direct answer (40-50 words)
Structure factual information in a format that’s easy for Google to extract
Use headings that clearly indicate the type of information that follows (How to, What is, Why, etc.)
Balancing SEO Optimization with User Readability
While incorporating keywords into headers for improved search engine visibility is beneficial, balancing SEO optimization and user readability is paramount. As much as we might want to please search algorithms, remember that you’re writing first and foremost for human beings.
Ensure your headings are:
Accurate: They should clearly convey what the subsequent section is about
Intriguing: Your headings should motivate readers to continue reading
Validating: Show that you’re providing value or solving a problem
Natural: Never sacrifice readability for keyword insertion
By marrying search engine visibility goals with the crucial human aspect of content consumption, you’ll ensure your hard work reaches and resonates with the audience it deserves.
Headings in Academic and Professional Writing
Different citation styles have specific requirements for how headings and subheadings should be formatted. Understanding these requirements is essential for academic and professional writing.
APA Style Heading Format
The American Psychological Association (APA) publication manual format is widely used in academic writing. It distinguishes five levels of headings with specific formatting requirements.
APA Heading Format Table:

MLA Style Heading Format
The Modern Language Association (MLA) style uses a simpler approach to headings compared to APA:
MLA recommends numbered sections with headings
All headings should use title case
Main sections use centered headings
Subsections use left-aligned headings
Further subdivision uses indented, italicized headings
Chicago Style Heading Format
The Chicago Manual of Style offers flexibility in heading formatting but recommends consistency throughout a document:
Heading levels should be clearly distinguished by size, style, or position
Chicago suggests using no more than three levels of headings
Recommended formatting includes centered headings for level 1, left-aligned for level 2, and indented run-in headings for level 3

FAQs on Headings and Subheadings
What is the difference between a heading and a subheading?
A heading is an overarching title that indicates a section’s main theme or subject. Headings are typically formatted with larger, bold text to grab readers’ attention quickly and act as signposts for those scanning content.
A subheading serves as a smaller, more detailed description under the main heading. Subheadings further divide sections into subsections, providing context and highlighting specific aspects of material under their respective headings. They help guide readers through content by making it easy to identify relevant information.
How many heading levels should you use?
The number of heading levels you should use depends on several factors:
Content length and complexity: Longer, more complex content may require additional heading levels to maintain clear organization.
Reader comprehension: Different audiences have different needs; technical content often benefits from more detailed subdivision.
Style guidelines: Some formats (like APA) specify heading level usage.
Platform requirements: Website structure and CMS capabilities may influence heading hierarchy.
In general, most articles or posts utilize 2 to 4 levels of headings. Using H1 for the title, H2 for major sections, and H3 for subsections is sufficient for most content. H4-H6 are typically reserved for highly structured, technical, or very lengthy documents.
Using too few heading levels can limit organization, while excessive use may create an overly complex structure that confuses readers. The key is finding the appropriate balance for your specific content needs.
How do I make my headings accessible for screen readers?
To ensure your headings are accessible for screen readers and comply with accessibility guidelines:
Use proper HTML semantic markup (H1-H6 tags) rather than styling text to look like headings
Maintain a logical hierarchy without skipping levels
Make headings descriptive and meaningful
Ensure each page has exactly one H1 tag
Keep headings concise but informative
Avoid using headings solely for visual styling
Test your content with screen readers or accessibility evaluation tools
Following these practices ensures that all users, regardless of their abilities or assistive technologies, can effectively navigate and comprehend your content.
