What Is H1 and H2 in SEO

What H1 and H2 Tags Are

H1 and H2 are HTML heading elements. HTML provides six levels, from H1 down to H6, and they exist to express the hierarchical structure of a document. The H1 is the main heading of a page - the single statement of what this page is about. H2 elements are the major section headings beneath it, each introducing a distinct part of the topic. H3 tags subdivide H2 sections, and so on down the scale.

Headings are not styling instructions. This is the most common misunderstanding in practice. Because browsers render H1 large and bold by default, people reach for heading tags to make text visually prominent and reach for paragraph tags with custom classes when they want a real heading to look smaller. Both habits break the semantic structure. Size and weight belong in CSS; heading tags belong to meaning.

That structure matters for three audiences. Readers scan headings to decide whether a page is worth their time and to jump to the part they need. Screen reader users navigate by heading level, making a correct hierarchy an accessibility requirement rather than a nicety. And search engines use headings to understand what a page covers, how its subtopics relate, and which passages answer which questions.

How to Use the H1 Correctly

Every indexable page should have one H1 that clearly states the page's subject. Modern HTML technically permits multiple H1 elements within sectioning content, and search engines can cope with them, but a single H1 remains the cleaner, safer, and more accessible choice. It removes ambiguity for assistive technology and forces you to be clear about what the page is for.

A strong H1 includes the page's primary topic in natural language, matches the content that follows, and reads as a complete thought rather than a keyword fragment. It should relate closely to your title tag without needing to be identical - the title tag competes in search results and benefits from brevity and brand signals, while the H1 speaks to someone who has already arrived and can be warmer or more descriptive.

Common H1 problems include pages with no H1 at all, which happens frequently on template-driven category and archive pages; H1 tags wrapped around a site logo in the header, which makes every page's main heading identical to the brand name; and H1 text stuffed with keyword variations that read awkwardly to any human.

How to Use H2 Tags Effectively

H2 tags divide your page into its major sections, and there is no meaningful limit on how many you should have. A short service page might need three; a comprehensive guide might use ten. The right number is however many distinct major sections your topic genuinely contains.

The most valuable practice is to write H2 headings that mirror the questions and subtopics people actually search for around your main subject. Look at the related questions in search results, the autocomplete suggestions, the subheadings competitors use, and the language customers use in support tickets or sales calls. Turning those into H2 sections does two things: it ensures you cover the topic comprehensively, and it makes individual passages of your page eligible to answer specific queries and appear in featured snippets and AI-generated summaries.

Keep H2 headings descriptive and self-contained. "Overview" tells a reader nothing; "How Domain Rating Is Calculated" tells them exactly what the section delivers. Someone skimming only your headings should come away understanding the shape of your argument.

Getting the Hierarchy Right

Headings should descend without skipping levels. An H1 followed by H2 sections, each optionally containing H3 subsections, is correct. An H1 followed immediately by an H4 because the H4 style looked better is not. Screen readers announce level numbers, and gaps in the sequence make navigation genuinely confusing.

Nesting should also reflect real relationships. If a section only makes sense as a component of the section above it, it should be an H3 under that H2, not another H2 at the same level. A useful test is to extract only the headings from a page and read them as an outline. If the outline makes sense on its own, your structure is sound. If it reads as a flat list of loosely related fragments, your content probably lacks organisation too.

Heading Mistakes That Cost You Traffic

Using headings for visual emphasis. Pull quotes, callouts, and prominent statistics styled as H2 tags pollute your outline with content that is not a section heading.

Skipping headings entirely on long pages. A two-thousand-word wall of paragraphs with no subheadings is punishing to read on mobile and gives search engines almost no structural signal.

Duplicating the title tag verbatim as the H1 across every page. This works but wastes an opportunity to speak differently to a visitor who has already clicked.

Keyword stuffing headings. Repeating the same phrase in every H2 reads as manipulation and makes content harder to scan.

Hiding headings with CSS to include extra keywords. This is a genuine risk, not a clever trick, and it undermines accessibility.

Letting templates generate meaningless headings. Sidebar widget titles, footer column labels, and "Related Posts" blocks marked up as H2 or H3 appear in your outline and dilute the structure of the actual content.

Auditing Your Heading Structure

Crawl your site and export the H1 and H2 data for every URL. Look for pages with zero H1 tags, pages with multiple H1 tags, duplicate H1 text across many URLs, and pages with no H2 tags despite substantial word counts. Template-level problems will cluster obviously, and fixing one component often resolves hundreds of pages at once.

Then review your most important pages individually. Read the heading outline in isolation, check that it covers the questions searchers ask, and confirm that the hierarchy descends logically. This exercise almost always reveals content gaps as well as markup issues, which is why heading audits tend to improve rankings more than their technical simplicity suggests. Well-structured, clearly sectioned content is also considerably easier for AI systems to parse and cite, tying heading discipline directly to your wider digital marketing visibility.

Final Thoughts

H1 and H2 tags are not decoration and they are not a ranking trick. They are the skeleton of your page: one clear statement of the subject, followed by well-named sections that cover it thoroughly. Get that skeleton right and everything else improves - readers find what they need faster, assistive technology works properly, search engines understand your coverage, and individual passages become eligible to answer specific queries. It is one of the least glamorous and most consistently rewarding pieces of on-page work available to you.
