Search Engine Optimization (SEO) isn't just a marketing term anymore—it's a core part of modern web development. Whether you’re building a personal portfolio, a SaaS product, or a content-heavy blog, good SEO practices can drive more traffic without paying for ads.

Here’s a quick guide to what modern SEO looks like from a developer’s point of view.

1. Semantic HTML Still Matters

Don’t underestimate the value of clean, semantic markup.

✅ Use <header>, <main>, <article>, <section>, and <footer> appropriately
✅ Use <h1> to <h6> headings to reflect your content hierarchy
✅ Use alt attributes on all images

This helps both accessibility and Google’s crawler.

2. Page Speed Is Ranking Gold

Google rewards performance.

• Optimize images with next-gen formats like WebP
• Lazy-load offscreen assets
• Use a CDN for static assets
• Minify and compress JS, CSS, and HTML

💡 Tools: Lighthouse, PageSpeed Insights, ImageOptim

3. Dynamic Sites? Use SSR or SSG

If you're using frameworks like Next.js, server-side rendering (SSR) or static site generation (SSG) ensures your content is visible to crawlers.

export async function getStaticProps() {
  const posts = await getAllBlogPosts();
  return { props: { posts } };
}
