We have a <header> main on the page where we normally put the logo image.
Within this <header> does the image require both alt and title to be interpreted by the correct search engines?
I would like to know if the search engine (Google in this case) will interpret <header> by reading the title property and thus associating it.
To answer your question quickly, by the research I did, and as you will see below, what is used for nomenclature is the alt in the case of the IMG tag.
But for a more in-depth response, with the intention of functional SEO, if your intention is to have your logo linked to your website, the best thing to do is to follow the standard schemes that are adopted for this purpose, such as schema.org which is known as microdata (microformat / microdata).
See: link
You can "baptize" your block where the logo is as Organization:
<div itemscope itemtype="http://schema.org/Organization">
<a itemprop="url" href="http://www.example.com/">Home</a>
<img itemprop="logo" src="http://www.example.com/logo.png"/></div>AnupdatedformofSchema.orgistouseasaSCRIPTtagwithin<head>:
<scripttype="application/ld+json">
{
"@context": "http://schema.org/",
"@type": "Organization",
"url": "http://www.example.com/",
"logo": "http://www.example.com/logo.png"
}
</script>
You can also use LocalBusiness with logo, as the following example:
<div itemscope itemtype="http://schema.org/LocalBusiness">
<p itemprop="name">Nome da Empresa</p>
<div>
<img itemprop="logo" src="logo.png" alt="Nome da Empresa">
</div>
</div>

Let's get down to business: Master Agency!
8 SEO tips to make a good title tag:
But change the title according to the content:
"Master Agency - Articles"
"Master Agency - Black Hat"
"Master Agency - Link Building"
That's because there will be no more than 70 characters in the search results for the title of a page ...
Attention! Not worth keyword spamming! "Seo master, seo tips, all about seo, seo tutorial, black hat seo, meta description seo, ..."
Use the keywords but with some sense: "Master Agency - All about SEO" =)

"Master Agency - Good morning, today I woke up thinking about new SEO techniques .." = (
"Master Agency - Articles | SEO on Title Tag "
A title for a page should follow your offer and search. When the page offers a browsing or search, it is recommended a descriptive title. However, when selling or offering a download, it should be made clear in the title that the purchase, download or any other action can be made on the site. "Master Agency - Download e-Books on SEO," or "Master Agency - Search for the best SEO books."
Set a default for the Title and follow it.
"Master Agency - Articles"
"Master Agency - Downloads"
=)
"Master Agency - Articles"
"Download Master Agency"
"buy books - seo tips"
Repeat the title of the page on h1 of the page, or something worth it, so the user will make sure that he got where he wanted and that his site offers what he needs. Not to mention that the search engine will love to find in the content of the page what the title tag says it has!
You can define in your header some information that will be indexed by the search engines, but will not be displayed to the user.
Example:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Definindo Header</title>
<style>
header h1 {
display: none;
}
</style>
</head>
<body>
<header>
<h1>Logo da Empresa X</h1>
<img src="#" alt="Logo da Empresa X">
</header>
</body>
</html>You define a title header for the logo just for semantic reasons, but leave it with a display: none in css.
