What Is an H2 Tag? Write Clear Headings and a Useful Page Outline
June 18, 2026

An H2 identifies a major section of a page. Use it to help readers find an answer and understand how the article is organized, rather than as a container for repeated keywords. A strong outline makes sense on its own, and the body delivers what each heading promises.
What an H2 heading represents
HTML heading levels express a hierarchy. An article can use H1 for its main topic, H2 for major sections, and H3 for subsections. That is a useful editorial pattern, not a ranking formula. Headings also support navigation with assistive technology.
The W3C heading tutorial explains this structural purpose. Font size alone does not establish the correct level: styling and document meaning are separate decisions.
Build the outline around the reader’s questions
Start with the reader’s questions. For a fictional booking-system guide, the reader may need selection criteria, cost boundaries, and implementation steps. Organize those decisions rather than copying a vendor’s feature list.
Reader question | Section answer | Possible heading |
|---|---|---|
What should we compare? | Requirements for the actual booking workflow | Choose criteria around your booking process |
What costs extra? | Initial, recurring, and integration costs | Check what the quote includes |
How do we launch? | Configuration, testing, and ownership | Test booking and changes before launch |
Check for repeated questions and overloaded sections. Split a section when its contents serve different reader tasks, not because it exceeds an arbitrary number of words.
Turn vague headings into specific promises
Vague heading | Specific alternative | Required supporting content |
|---|---|---|
Benefits | Where booking administration can be reduced | Tasks removed and tasks that remain |
Things to note | Three operational responsibilities to check | Configuration, training, and maintenance |
Pricing | What initial and recurring fees include | Inclusions, exclusions, and conditions |
Conclusion | What to confirm before shortlisting | Owners, evidence, and next actions |
These are editorial examples, not demonstrated ranking improvements. A more specific heading creates a stronger obligation: if it promises three responsibilities, the section must explain all three. Avoid outcome promises the evidence cannot support.
Use H2 and H3 to show sections and subsections
Level | Fictional outline | Purpose |
|---|---|---|
H1 | How to choose a booking system | Whole-page topic |
H2 | Choose criteria around your booking process | Major section |
H3 | Check bookings and change requests | One selection criterion |
H3 | Check cost and maintenance ownership | Another criterion |
H2 | Test booking and changes before launch | Next major section |
Returning from H3 to H2 closes a subsection and starts the next major section. Avoid skipping downward from H2 to H4. Do not turn button text or decorative emphasis into headings merely to obtain larger type.
Avoid heading-count and keyword formulas
There is no universal H2 quota, ideal heading length, or keyword repetition count. Google’s SEO Starter Guide does not prescribe such formulas. Let the material and reader decisions determine the structure.
Use topic language naturally, without repeating the same long phrase everywhere. A single clear article H1 is a sensible editing convention; multiple H1s are not an automatic penalty. The goal is an understandable hierarchy.
Check the actual structure behind the CMS styling
After editing in a CMS, inspect the actual HTML or accessibility heading list. Check generated tables of contents, cards, and related-guide headings as well as the article body. Visual formatting can hide structural mistakes.
Use real text for important headings. If an image contains essential information, provide appropriate alternatives and context; Google’s image guidance covers these signals. Search-result titles are produced through a different process, described in the title-link documentation. An H2 cannot fix the result wording by itself.
Review the outline on its own before publication
Editing worksheet | Completed example |
|---|---|
Question | Can monthly fees represent total cost? |
Section answer | Compare initial, additional, and maintenance scope |
Evidence | Quote items and an explicitly hypothetical calculation |
H2 | Check what the quote includes |
H3s | Setup, integrations, and maintenance |
Body match | Each inclusion and exclusion is explained |
- Read headings alone and check the sequence.
- Remove duplicated promises and missing decisions.
- Verify every number, condition, and effect promised.
- Confirm the actual levels support accessible navigation.
Ask another reader to review the outline before publication, then compare it with the body. That exercise reveals gaps more usefully than scoring headings by character count.
