Content Template Secrets: How to Build an Astro Site That Google Loves

Astro empowers developers to build content-focused websites that are fast, accessible, and search-engine friendly. In this guide, we reveal how to construct content templates that shine in both SEO rankings and user experience—and become Google’s favorite.

🔤 Semantic HTML: Structure That Makes Sense

Using correct semantic tags improves accessibility and helps search engines better understand content structure.

✅ Key Elements:

<header>   → For logo, site title, main nav
<main>     → Primary page content
<article>  → Individual blog posts or content blocks
<aside>    → Sidebars, callouts, or related links
<nav>      → Main or sub-navigation
<footer>   → Copyright, links, CTAs

Astro encourages clean HTML-first markup. Use components and slots to maintain semantics across your layouts.

🚀 Core Web Vitals in Template Design

Google uses Core Web Vitals as ranking signals. Astro makes these easier to optimize.

🖼️ Lazy Loading with <Image />

Use the astro:assets integration:

---
import { Image } from 'astro:assets';
import banner from '../assets/banner.jpg';
---

<Image src={banner} alt="Hero banner" loading="lazy" />

Images are optimized and lazy-loaded by default.

🔤 Font Optimization

<link rel="preload" href="/fonts/inter.woff2" as="font" type="font/woff2" crossorigin="anonymous">

And in CSS:

font-display: swap;

This avoids layout shifts and improves LCP and CLS scores.

🗺️ Sitemap, Robots.txt, RSS: Auto-Generated

Sitemap

npm install @astrojs/sitemap

// astro.config.mjs
import sitemap from '@astrojs/sitemap';
export default {
  site: 'https://example.com',
  integrations: [sitemap()],
};

Robots.txt

Create a simple /public/robots.txt:

User-agent: *
Allow: /
Sitemap: https://example.com/sitemap-index.xml

RSS Feed

Use @astrojs/rss:

npm install @astrojs/rss

Generate feed with content collections or Markdown pages.

🍞 Breadcrumbs, Navigation, Internal Linking

Breadcrumb Component Example:

<nav aria-label="breadcrumb">
  <ol>
    <li><a href="/">Home</a></li>
    <li><a href="/blog/">Blog</a></li>
    <li aria-current="page">Current Article</li>
  </ol>
</nav>

Internal Navigation

• Use <a href="/related-article/"> with descriptive anchor text
• Avoid JS-only routing for critical content
• Group related posts by tags or collections

📈 Analytics & SEO Tooling

Google Tag Manager (GTM)

<!-- Head -->
<script async src="https://www.googletagmanager.com/gtag/js?id=G-XXXXXXX"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());
gtag('config', 'G-XXXXXXX');
</script>

Plausible Analytics

<script async defer data-domain="example.com" src="https://plausible.io/js/plausible.js"></script>

Both load lightweight and respect user privacy.
