Why Semantic HTML Matters
Semantic HTML helps both search engines and assistive technologies (like screen readers) understand the content and its structure. Proper use of semantic elements enhances your website's SEO by making your content more meaningful to search engines and improves accessibility by offering clear navigation for users with disabilities.

Let's take a look at the diagram which will show us what a page with semantic HTML will look like and what it will be without semantic HTML.

Core Semantic Elements for SEO and Accessibility

1. <header>

• Purpose: This element defines the introductory section of a page or a section, often containing navigation links, logos, and site titles.
• How to Use: Place your site’s header within the <header> tag at the top of your page or a specific section.

<header>
  <h1>webdevtales</h1>
  <nav>
    <ul>
      <li><a href="#">Home</a></li>
      <li><a href="#">About</a></li>
    </ul>
  </nav>
</header>

• SEO Benefit: Helps search engines identify the primary navigation and title.
• Accessibility Benefit: Allows screen readers to easily navigate the page's top section.

2. <main>

• Purpose: Encloses the main content of your webpage, ensuring search engines and assistive technologies focus on the core information.
• How to Use:Wrap your primary content with the tag, excluding headers, footers, and sidebars.

<main>
  <h2>Welcome to My Blog</h2>
  <p>This is where the main content goes.</p>
</main>

• SEO Benefit: Indicates where the most important content starts.
• Accessibility Benefit: Helps users with assistive technology skip repetitive content (like headers) and go directly to the main content.

3. <section>

• Purpose: Divides content into thematic groups, making it easier for search engines and users to digest.
• How to Use: Use to group related content that has its own title or purpose.

<section>
  <h3>Latest Articles</h3>
  <p>Read about our latest updates.</p>
</section>

• SEO Benefit: Helps organize content for better indexing.
• Accessibility Benefit: Improves navigation, as screen readers can move from section to section.

4. <article>

• Purpose: Wraps self-contained content that can stand alone, like blog posts or news articles.
• How to Use: Use for independent pieces of content within a webpage.
