Multiple H1 Tags
Your page contains more than one h1 tag, creating topical confusion for both search engines and users. Best practice dictates exactly one h1 per page to establish clear focus and proper content hierarchy. Multiple h1 tags dilute your page's main message and signal poor HTML structure to search algorithms.
What Are Multiple H1 Tags?
Multiple h1 tags occur when a page's HTML contains two or more <h1> elements, each declaring itself as the primary headline. In proper HTML structure, the h1 tag represents the single most important heading that defines your page's main topic.
The h1 sits at the top of the heading hierarchy, functioning as the root node from which all other headings (h2, h3, etc.) branch. When you include multiple h1 tags, you're essentially telling search engines "all of these topics are equally important," which creates ambiguity about your page's actual focus.
These elements live in your page's HTML body, typically appearing as <h1>First Headline</h1> and <h1>Second Headline</h1> at different points in your content. While HTML5 technically allows multiple h1 tags when using sectioning elements, search engines and SEO best practices still recommend a single h1 for optimal clarity.

The SEO Impact
Multiple h1 tags create several ranking and usability issues.
Topical Dilution: Search engines use the h1 to identify your page's primary topic and target keyword. When you have multiple h1 tags with different keywords or topics, you fragment your topical authority. Google can't determine which topic deserves ranking priority, weakening your relevance signals for all potential keywords.
Content Hierarchy Confusion: Proper HTML heading structure follows a clear outline, h1 for the main topic, h2 for major sections, h3 for subsections. Multiple h1 tags break this hierarchy, making it unclear how your content is organized. Search engines rely on this structure to understand content relationships and importance.
Reduced Keyword Emphasis: Having one h1 concentrates keyword weight and topical signals in a single element. Splitting across multiple h1 tags distributes this weight, reducing the ranking power of your primary target keyword compared to competitors with focused single-h1 approaches.
Accessibility Problems: Screen readers use heading hierarchy as navigation landmarks. Multiple h1 tags confuse assistive technologies about the document outline, creating poor experiences for visually impaired users and violating WCAG accessibility guidelines.
Common Causes
Several typical scenarios lead to pages with multiple h1 tags.
Template Component Conflicts: Page builders and component-based frameworks sometimes include h1 tags in multiple reusable components. For instance, a header component might use <h1>{{ site.name }}</h1> for the logo, while a hero section component also uses <h1>{{ page.title }}</h1>, resulting in two h1 tags per page.
HTML5 Sectioning Misunderstanding: HTML5 introduced sectioning elements (<article>, <section>) with the idea that each section could have its own h1. Some developers interpreted this as permission to use multiple h1 tags, but search engines never fully adopted this document outline algorithm, making single h1 still the best practice.
Content Management System Defaults: Certain CMS themes or plugins auto-generate h1 tags for various page elements like titles, widget headings, or sidebar headers. Combined with the main content h1, this creates multiple instances without the site owner realizing it.
Legacy Code or Migration Issues: When updating sites or combining content from multiple sources, old HTML with multiple h1 tags may persist. Teams focused on visual design may not notice the underlying HTML structure issues.
How Zignalify Detects This
Our crawler analyzes your page's complete rendered HTML, including all JavaScript-generated content. We convert your page into a standardized markdown format that preserves heading structure while simplifying analysis.
Zignalify scans this markdown representation for h1 heading patterns by looking for lines that begin with a single hash symbol (#) followed by text. We count every instance of this pattern across your entire page content.
When we detect more than one h1 tag on a single page, we flag it as a multiple h1 issue. Our reporting includes the exact count of h1 tags found and displays the text content of each one, allowing you to identify which elements need conversion to lower heading levels.
We perform this check on both desktop and mobile versions because heading structure should remain consistent across devices, and some responsive designs inadvertently duplicate headings for different viewports.
Step-by-Step Fix
Resolving multiple h1 tags requires converting secondary headlines to appropriate lower-level headings.

Platform-Specific Guidance:
WordPress: Inspect your page using browser developer tools to identify all h1 tags. In the block editor, click each heading block that shows as h1 and change it to "Heading 2" or "Heading 3" in the block settings panel. Keep only your main page title as h1. For theme-generated h1 tags (like in headers or sidebars), edit your theme's template files or use a child theme to change those elements to div or p tags with appropriate CSS classes.
Shopify: Review your theme's liquid templates to find multiple h1 usage. Common locations include sections/header.liquid, sections/hero.liquid, and product/collection templates. Edit these files to change secondary h1 tags to h2 or semantic div tags. Keep only the main page title (product name, collection name, page heading) as h1. Test thoroughly after changes to ensure visual styling remains correct.
Next.js/React: Audit your component structure to identify which components render h1 tags. Use React DevTools or search your codebase for <h1> elements. Ensure only your page-level component renders an h1, while all reusable components (headers, sections, cards) use h2, h3, or styled div elements. Create a component hierarchy that maintains semantic heading order.
// Correct approach
export default function ProductPage() {
return (
<>
<h1>{product.name}</h1>
<section>
<h2>Features</h2>
<p>Feature content...</p>
</section>
<section>
<h2>Reviews</h2>
<p>Review content...</p>
</section>
</>
);
}
Best Practices
Maintain optimal heading structure with these strategies.
Identify Your Primary Topic: Before adding any headings, determine your page's single main topic. This becomes your h1. Everything else on the page supports this main topic and should use lower heading levels (h2, h3).
Use H2 for Major Sections: Your primary section headers should all be h2 tags, not additional h1 tags. Think of h2 as chapter titles within your h1 book title. For example, if your h1 is "Complete Email Marketing Guide," your h2 tags might be "Setting Up Your First Campaign," "List Building Strategies," etc.
Maintain Hierarchical Order: Never skip heading levels. Follow h1 with h2, then use h3 for subsections within h2 content. Don't jump from h1 directly to h3. This creates a logical outline that both search engines and screen readers can parse correctly.
Audit Component Templates: Review all reusable components, headers, widgets, and templates to ensure none inadvertently include h1 tags. Reserve h1 exclusively for page-specific main titles, not global site elements.
Style With CSS, Not HTML: If you need multiple large, visually prominent headlines, use CSS to style h2 or h3 tags to look like main headlines. Separate semantic HTML structure from visual presentation. A large, bold h2 can look identical to an h1 while maintaining proper hierarchy.
Test With Outline Tools: Use browser extensions or accessibility tools that generate document outlines from your heading structure. A proper outline shows one h1, multiple h2 sections, and h3 subsections, creating a clear content hierarchy.
FAQs
Is having multiple H1 tags a penalty in Google?
No, Google doesn't penalize sites for multiple h1 tags, and Google's John Mueller has stated they can handle pages with multiple h1 elements. However, this doesn't mean it's optimal. While not a penalty, multiple h1 tags create topical ambiguity that can weaken your relevance signals for target keywords. Best practice remains using a single h1 to maximize topic clarity and keyword focus, even if multiple h1 tags don't trigger explicit penalties.
Does HTML5 allow multiple H1 tags?
HTML5's specification technically allows multiple h1 tags when using sectioning elements like <article> and <section>, with the idea that each section resets the heading hierarchy. However, browsers and search engines never fully implemented the HTML5 document outline algorithm this relies on. In practice, assistive technologies and SEO crawlers still treat all h1 tags as equal importance, regardless of sectioning. Therefore, SEO best practice remains using a single h1 per page.
How do I fix multiple H1s without breaking my design?
Identify which headline is your true primary topic (usually your page title), keep that as h1, and convert all others to h2 or h3. If you need secondary headings to maintain the same visual size and prominence as your h1, use CSS to style them identically. Create a CSS class like .heading-large that applies the same font size, weight, and spacing to both h1 and styled h2 elements. This maintains your design while fixing the semantic HTML structure.
