Heading structure: using H1 to H3 correctly for SEO

A website without clear headings is like a book without chapters: you cannot find your way around. This is exactly where the heading structure comes in. H1, H2 and H3 are not just large, bold type, they are the framework that both your readers and Google orient themselves by. And although that sounds technical, at its heart it is a question of clarity. In this article I show you how to use H1 and H2 correctly for SEO, without it getting complicated.
The best part: if you do it well for your readers, you almost automatically do it well for Google too.
What headings actually are
Headings are the titles and subheadings on a page. In the code they appear as H1 to H6, the number gives the level. Think of it like an outline:
- H1 is the main title of the page, the big topic. There is exactly one of these.
- H2 are the main sections, the chapters within the topic.
- H3 are sub-points within an H2 section.
Important: a heading is not the same as text that someone has simply formatted large and bold. For Google, what counts is what is marked as a real heading in the code, not what merely looks like one visually.
The H1: one title, one topic
The H1 is the most important heading of a page. It says in one sentence what it is about. Three simple rules:
- Only one H1 per page. Several main titles confuse, like a book with two titles on the cover.
- Name the main topic. If someone reads only the H1, it should be clear what awaits them.
- Build in the important word. If your page offers «garden care in Winterthur», exactly that belongs in the H1, naturally phrased, not forced.
A common mistake: the company logo at the top left is set as the H1. Then Google thinks the main topic of every page is your company name, and not what the page is really about.
H2 and H3: the hierarchy makes the difference
Here lies the core of «H1 H2 SEO»: it is about the order. Headings should follow one another logically from top to bottom, without skipping levels.
A clean example for a service page:
- H1: Garden care in Winterthur
- H2: Our services
- H3: Lawn care
- H3: Hedge trimming
- H2: How the collaboration works
- H2: Frequently asked questions
You see: each H2 is a chapter, each H3 a sub-point of it. What you should avoid is a jump from H1 straight to H3, or choosing a level only because the type looks nice. If you need a particular size, solve that through the design, not by choosing the wrong heading level.
Why Google cares about this at all
Google does not read your page like a person, but gets an overview from the headings: what is it about, how is it ordered, what are the focal points? A clear structure helps the search engine classify the content correctly and find fitting sections for a search query.
Even more important is the second effect: a good heading structure also helps people. Most do not read a website word for word, but skim it. Clear subheadings allow them to jump quickly to the right spot. And a visitor who finds what they are looking for stays longer and is more likely to get in touch. It is exactly this that has an indirect positive effect on ranking.
Accessibility: the often forgotten bonus
There is one more reason that is rarely mentioned. People who use a screen reader often navigate from heading to heading to get an overview. A logical structure is for them not a comfort, but the basis for being able to use the page at all. Good structure is therefore not only SEO, it is also a matter of decency.
How to check your own page
You do not have to be a professional for this. A simple test: read only the headings of your page, from top to bottom. Do they make a sensible, short summary? Then the structure is probably good. If you stumble while doing it, Google probably does not know any better either.
- Is there exactly one H1, and does it name the topic?
- Do the levels follow logically, without jumps?
- Are the subheadings meaningful rather than just «More on this»?
A well-considered heading structure is one of the most inconspicuous, but most effective SEO measures, and it costs nothing except a little care in the build.
