Meta Description for SEO

The meta description summarizes the page content. Search engines may show it as the result snippet.

<meta
  name="description"
  content="Learn HTML SEO with examples, best practices, tools, and beginner-friendly tips."
/>

HTML Headings for SEO

Headings help users and search engines understand page hierarchy. Use one clear <h1> and organize subtopics with <h2> and <h3>.

<h1>HTML SEO Guide</h1>
<h2>Title Tags</h2>
<h2>Meta Descriptions</h2>
<h3>Good Meta Description Example</h3>

Semantic HTML for SEO

Semantic HTML gives meaning to your page structure. It helps search engines, browsers, assistive technologies, and developers understand the role of each section.

<main>
  <article>
    <header>
      <h1>HTML SEO Guide</h1>
    </header>

    <section>
      <h2>SEO Basics</h2>
      <p>Clean HTML improves crawlability and content understanding.</p>
    </section>
  </article>
</main>

HTML Image SEO

Use descriptive image file names.
Add meaningful alt text.
Set image width and height to reduce layout shift.
Use compressed images and modern formats like WebP.
Use lazy loading for below-the-fold images.

<img
  src="/images/html-seo-checklist.webp"
  alt="HTML SEO checklist for beginners"
  width="800"
  height="450"
  loading="lazy"
/>

Internal Links for SEO

Internal links connect related pages and help search engines discover your content. Use descriptive anchor text instead of generic phrases.

Canonical and Robots Tags

Canonical tags help search engines understand the preferred URL. Robots meta tags control indexing and link following.

<link rel="canonical" href="https://www.phpkingdom.com/tutorials/html/seo/" />

<meta name="robots" content="index, follow" />

Structured Data and Schema Markup

Schema markup helps search engines understand page type, author, breadcrumbs, articles, products, reviews, and other structured information.

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Article",
  "headline": "HTML SEO Guide for Beginners",
  "description": "Learn HTML SEO with examples and best practices.",
