What is an H2 Tag?

H2 tag: major sections under the H1

The H2 tag marks the first level of subdivision below the H1 tag. If the H1 names the page topic, H2s name the chapters: "Benefits," "How it works," "Pricing," "FAQ." Readers skim H2s before committing to paragraphs; parsers use them to segment topical blocks.

H2s are the workhorse heading for long-form on-page SEO content—guides, product detail tabs, documentation, and comparison pages.

Position in the heading hierarchy

H1  Primary topic (one per page)
├── H2  Major section 1
│   └── H3  Detail under section 1
├── H2  Major section 2
└── H2  Major section 3

H2 is not "slightly smaller H1." It is explicitly subordinate. Competing H1-sized visuals should not all use <h2> unless they are true peer sections under one H1.

H2 vs H1: distinct jobs

<h1>Complete guide to robots.txt</h1>
<p>Intro paragraph...</p>

<h2>What robots.txt controls</h2>
<p>...</p>

<h2>Common disallow mistakes</h2>
<p>...</p>

<h2>Testing with Search Console</h2>
<p>...</p>

When to add an H2

Add H2s when:

• A section exceeds ~150–200 words and introduces a new subtopic
• Users would benefit from a table of contents jump link
• You answer distinct questions in one URL (combined guide)
• Product pages separate specs, reviews, and shipping

Skip H2s when:

• The page is a short confirmation or utility screen
• A single paragraph fully answers the query
• Fake H2s exist only to repeat keywords

H2 patterns that perform well

Question-style H2s

Useful for informational intent and snippet eligibility:

<h2>What is crawl budget?</h2>
<p>Crawl budget is the resources Google allocates...</p>

<h2>How do you increase crawl budget?</h2>
<p>You do not directly "buy" budget, but you can...</p>

Task-oriented H2s

Strong for how-to and product education:

• Install the tracking snippet
• Connect your domain
• Compare plans

Entity-specific H2s

Comparison pages:

<h2>Crawlox vs manual spreadsheet audits</h2>
<h2>Crawlox vs enterprise suites</h2>

Each H2 should be followed by substantive body copy, not a single sentence stub.

H2 and table of contents plugins

Many CMS TOC widgets auto-generate from H2/H3. Benefits:

• Jump links improve UX and time on page
• Anchor URLs (#section-id) can earn sitelinks-style jumps

Ensure:

• id attributes are stable across edits
• H2 text is concise for TOC labels
• Mobile TOC does not replace visible headings

H2 styling vs semantics

Design teams often size H2 visually smaller than marketing hero text. Semantic level matters independently:

H2 mistakes in SEO audits

• Keyword list H2s — Best SEO tool Chicago SEO agency SEO services
• Duplicate H2 text across paginated archives
• Empty sections — H2 followed by nothing or only ads
• H2 in sidebar that repeats on every URL (template noise)
• Accordion titles as non-headings — lose outline benefits unless marked up

H2 for ecommerce and templates

Product templates often use H2 for:

Customize H2s when generic labels waste topical signals—Technical specifications beats Details for electronics.

Measuring H2 structure quality

Manual rubric per template:

1. Does every H2 introduce at least two paragraphs or a list/table?
2. Can H2 order be shuffled without breaking logic? If yes, outline is weak.
3. Do H2 strings appear in Search Console queries as impressions?
4. Are H2s unique within the site for cornerstone content?

Crawl tools can count H2 frequency and flag URLs with H1 but zero H2 on long word counts—often missing structure.

H2 accessibility

• Screen reader users navigate by heading level; consistent H2 usage speeds scanning
• Do not use H2 for sidebar "Related posts" if those are navigational asides—consider <nav> with lower headings

H2 and internationalization

Translated pages should localize H2 strings, not only body paragraphs. English H2s on non-English URLs confuse users and dilute relevance signals.

Maintain heading glossary per locale so translators preserve intent, not literal keyword lists.

How Crawlox helps with H2 tags

Crawlox extracts heading outlines per URL, highlighting long pages without H2 structure or templates with repetitive H2 boilerplate across thousands of paths. Use crawl exports to standardize section patterns on guides and product templates—where H2 clarity most affects scannability and topical segmentation.
