Understanding HTML and SEO Value
HTML uses opening and closing tags to tell browsers how to display content. The syntax looks like this:
<p>This is a paragraph.</p>Everything between <p> and </p> is the content that appears on your page. Google’s crawlers read these tags to understand structure—headings show hierarchy, links show relationships, and lists show importance.
Primary Tag Categories
- Structure tags – define the layout of a webpage.
- Formatting tags – style the text and emphasize content.
- Media tags – handle images, videos, and embeds.
- Data tags – create tables and structured layouts.
- Interactive tags – build forms and user inputs.
Basic Structure Tags
Every web page starts with a few essential tags that define its document type and content area. Let’s go through them.
<!DOCTYPE html>
This declaration appears at the very top of an HTML file. It tells the browser the document type and version. It has no closing tag.
<html> ... </html>
Everything on your web page lives inside this pair. It’s the root container for the entire site.
<head> ... </head>
Holds metadata, scripts, CSS links, SEO titles, and descriptions. Not visible on the page but critical for search engines.
<body> ... </body>
All visible content—text, images, videos, tables—goes here. Every Servantarinze blog post’s body begins with the read-time calculator and ends with the FAQ schema inside this tag.
