Tags: the foundations of the web
What is an HTML tag?
HTML, or HyperText Markup Language, is the markup language used to create web pages. HTML tags are the basic building blocks of this language and are used to structure and format the content of a page. Each tag is defined by angle brackets ( " < " And " > » ) and may have an attribute which specifies how it should be interpreted.
➡️ Example of a simple tag: <p>This is a paragraph.</p>

The structure of HTML tags
The opening and closing tags follow a hierarchical structure.
In our example, <p>This is a paragraph.</p>,
the paragraph as by <p> and ends with </p>This structure ensures that the browser correctly translates the content and displays it appropriately.
➡️ Here is a more complex example to illustrate this hierarchy:
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<h1>Interior designer</h1>
<p>The text in paragraph form.</p>
</body>
</html>
In this example, <!DOCTYPE html> is the root tag of the document written in HTML5. Inside it, there are several sub-tags, such as <head> (header) or <body> (body text). Each of them has a specific role in the structure and functioning of the page.
HTML attributes
HTML tags can also have attributes that provide additional information.
➡️ Example for coding a hyperlink :
<a href="/en/ »https://www.exemple.com »/">Visit our website</a>
Here, the href attribute has the value of the URL to which the link redirects.
➡️ Example for coding an image :
<img src= »appartement.jpg » alt= »Modernizing a Haussmannian apartment">
Here, the img attribute has the value of the displayed image. The src (source) attribute indicates the path to the image (here, "apartment.jpg"). The ALT attribute designates the alternative text that is displayed if the image cannot be loaded due to a technical problem or if the user uses a screen reader (visually impaired people). In SEO, the ALT attribute is essential for referencing images.

HTML tags in SEO to structure your pages
In web writing, the writer uses on-page and off-page HTML tags to create structured and optimized content. They indicate the importance and hierarchy of the content to search engines (Google, Bing, etc.). Tagging also improves the readability and comprehension of the content for Internet users. What HTML tags should you know? Here's an overview!
The beacon
The title tag is represented by a clickable blue link in the Google results page. It plays a major role in SEO and must attract the attention of Internet users.
Example :
The beacon <meta description>
The meta description tag summarizes the content of a web page and must arouse the interest of Internet users. This brief description is visible under the blue link in the SERP (results page).
Example : <meta name= »description » content= »Découvrez des secrets de décoration intérieure pour créer un chez-vous élégant et chaleureux. Transformez votre espace avec nos astuces. » />
The beacon <h1>
The H1 tag represents the main title of the web page (editorial title visible on the page). The H1 can be identical to the title.
Example : <h1>Discover interior design trends</h1>
The tags <h2>, <h3>, <h4>, <h5>, <h6>
THE subtitle tags <h2>, <h3, <h4>, etc. prioritize content to guide readers and web crawlers through your words.
Example : <h2>Bedroom decoration</h2>
Note: Remember to carefully follow the order of H1 to H6 tags when structuring your page. Start with H1 for the main title, then H2 for the section titles, and so on. For example, avoid going directly from H2 to H4, as this can disrupt the structure and harm accessibility and SEO.

Example : <p>Transform your living space into a haven of peace with our interior design ideas.</p>

HTML and SEO Comments
HTML comments are pieces of code in web pages. They provide space for developers to add annotations, reminders, tips, and more. Think of them as sticky notes that are invisible to site visitors. So, are they read by search engine robots (Googlebot)? According to John Mueller, a member of the Google Search team, HTML comments are ignored when indexing content. They therefore do not serve as a hiding place for keywords that could boost your SEO! HTML comments do not change SEO directly, but behind the scenes, they can have beneficial effects.
