I did not quite understand your question, but I'll try to answer what I understand.
The order of the headers h1, h2, h3, ... does not "interfere" on the page. This goes according to your layout and how you prefer.
See this example with several <h1>
on the page:
<h1>PRINCIPAL</h1>
<h2>ASSUNTO 1</h2>
<h3>SUBTITULO DO H2</h3>
<h1>PRINCIPAL 2</h1>
<h2>ASSUNTO 2</h2>
<h3>SUBTITULO DO H2</h3>
<h1>PRINCIPAL 2</h1>
<h2>ASSUNTO 3</h2>
<h3>SUBTITULO DO H2</h3>
</section>
<section class="lado esquerdo"> <nav></nav> <aside>outros elementos e assuntos <article>outros elementos e assuntos </section>
</section>
Now, note that if your concern is SEO , the approach changes. For this, several factors are taken into account, including <h1>
. For this, one must take into account some factors, such as:
1 - H1 with the main idea keyword
2 - H2 with the keywords of the main idea elements
3 - H3 to further divide the elements and facilitate the understanding and visualization of people and robots.
Note a practical example of using them:
Suppose you want to make a car sales site called cars.com.
<h1>
The largest list of new, used and used cars on the internet
Please note in the above H1 example that some possible site keywords have been used and the text is written in a way that the user can understand.
<h2>
Sell Fiat Cars
In the H2 text we have something more specific, that is, it is a subsection of H1, and again we put some keywords of the site in the H2, this helps a lot the search engines and the user to find what they need in the site
<h3>
Sale of Fiat Punto Cars
As in H2, H3 has to be a complement to the upper H #. And this rule must be followed up to the H6 tag.
Note: You'll find more about it if you use the keyword Heading Elements or Heading Tags.
