Yes, it is important to use only one tag <h1>
, because this tag indicates the main subject addressed on your page, the main focus of the page in question.
The other Heading tags as <h2><h3><h4><h5>
are like sub-titles on your page, and speaking of SEO, it would be like complementary keywords.
Examples of Heading Tags:
<h1>Buffet Infantil da Carochinha</h1>
<h2>Festas temáticas</h2>
<h3>Festas do Barney</h3>
<h3>Festas dos Angry Birds</h3>
<h3>Festa da galinha pintadinha</h3>
<h2>Venha visitar a casa na Vila Olímpia - São Paulo</h2>
<h3>Ponto de referência</h3>
<h3>Estacionamento</h3>
Note that the content of Heading tags starts from the most relevant <h1>
for the least relevant <h3>
, where <h1>
is the main subject of the site, and the other, subjects related to the main content of <h1>
in question, which yes, can be repeated, because the main focus is maintained, clarifying to the user, what the page presents mainly, and this topic, yes, with subtitles related to the title, which may be yes, more than one.

This goes against much that I’ve read around. Is this still valid? taking into account that the video is from 2009.

<h1>
is the main focus of the page, so there’s no reason to split the main focus into 2, it makes more sense to have a single<h1>
and maybe 2<h2>
with main subtitles.– Marcelo Aymone
That’s exactly what I said, there’s no problem using more than one but it’s best to avoid.
