Introduction
SEO (Search Engine Optimization) is a set of strategies to help your website rank higher on Google and other search engines. As a developer, understanding technical SEO is crucial to build sites that perform well, attract organic traffic, and get noticed.
Why SEO Matters
- Most web traffic comes from organic search.
- SEO boosts conversions (clicks, sign-ups, sales).
- Technical SEO improves site speed and user experience.
- Knowing SEO makes you a more valuable developer.
Core SEO Techniques with Code Examples
Meta Tags (Title & Description)
<head>
<title>StasX’s Awesome Dev Site — Programming & AI</title>
<meta name="description" content="Learn programming, AI, and web development with a certified Ukrainian developer. Tutorials, projects, courses.">
<meta name="keywords" content="programming, AI, web development, SEO, StasX">
</head>
Why:
- Title should be unique and under 60 characters.
- Description summarizes the page (up to 160 characters) and appears in search results.

- Keep URLs short and meaningful.
- Use hyphens to separate words.
- Avoid unnecessary parameters and numbers.
Speed Optimization (Minify & Lazy Loading)
Minify CSS and JavaScript:
npm install -g clean-css-cli uglify-js
clean-css -o style.min.css style.css
uglifyjs script.js -o script.min.js
Use lazy loading for images:
<img src="photo.jpg" loading="lazy" alt="description of image">
Mobile Responsiveness
@media (max-width: 768px) {
body {
font-size: 16px;
}
nav {
display: none;
}
}
