HTML - SEO-relevant HTML

What it actually means

Search engines rely heavily on HTML structure to understand, rank, and display your content. SEO is not just keywords; it starts with correct HTML.

How to use it correctly

Key elements:

Headings

  • One clear <h1> per page

  • Logical hierarchy (h1 → h2 → h3)

  • Do not skip levels for styling

Images

<img src="product.jpg" alt="Red running shoes">

  • alt describes the image meaningfully

  • Required for accessibility and image search

Metadata

<title>Product Name | Brand</title>
<meta name="description" content="Short, clear page summary">

Why this matters

  • Search engines extract meaning from headings

  • Proper structure improves featured snippets

  • Accessible pages rank better

  • Metadata affects click-through rate

SEO tools cannot fix bad HTML structure.

Common mistakes

  • Multiple <h1> used for styling

  • Missing or empty alt attributes

  • Overusing <div> for everything

Practical rule

If a search engine can understand your page without CSS or JS, your HTML is SEO-correct.
