SEO Best Practices
Comprehensive SEO patterns for web applications built with React and Laravel. Contains 31 rules across 8 categories covering Core Web Vitals, technical SEO, structured data, performance, social sharing, and mobile-first indexing. Supports both coding reference and audit mode.
Metadata
- Version: 1.2.0
- Scope: Laravel Blade and Laravel + Inertia.js + React
- Rule Count: 31 rules across 8 categories

How to Audit
When the user asks to "audit SEO", "check SEO", or "review SEO" — run the checklist below against their codebase.
Audit Step 1: Determine Scope
- If arguments provided (
$ARGUMENTS): audit only those pages or files
- If no arguments: audit all pages and layouts in the codebase
Audit Step 2: Detect Project Type
Use the detection logic in "Step 1: Detect Project Type" below to determine Laravel Blade vs Laravel + Inertia + React.
Audit Step 3: Run SEO Checklist
Work through every item below. For each, output:
- PASS — brief confirmation of what was verified
- FAIL — exact
file:line, description of the issue, and fix recommendation
- N/A — if the check does not apply to this project
Core Web Vitals
Technical SEO
On-Page SEO
Structured Data
Performance SEO
Social Sharing
React/SPA SEO (if applicable)
Mobile-First
Audit Step 4: Summary
End the audit with:
## SEO Audit Summary
- **PASS**: X checks
- **FAIL**: X checks
- **N/A**: X checks
- **Top Priority Fixes**: (list the 3 most impactful FAIL items)
When to Apply
Reference these guidelines when:
- Running an SEO audit on a codebase
- Adding meta tags (
<title>, description, canonical, robots)
- Implementing structured data (JSON-LD / Schema.org)
- Optimizing Core Web Vitals (LCP, INP, CLS)
- Setting up Open Graph and Twitter Card meta tags
- Creating sitemaps and robots.txt
- Building SEO-friendly React SPAs
- Configuring Laravel SEO middleware and packages
- Optimizing images, fonts, and loading performance for search
Step 1: Detect Project Type
Always check the project stack before giving advice. Different stacks need different SEO approaches.
Check package.json and project structure:
| Signal | Project Type |
|---|
@inertiajs/react in dependencies | Laravel + Inertia + React |
resources/views/**/*.blade.php only (no React) | Laravel Blade (server-rendered) |
If Laravel Blade: Apply tech-, onpage-, schema-, perf-, social-, mobile- rules. Meta tags go in Blade layouts. Sitemaps via spatie/laravel-sitemap. Skip spa- rules — pages are already server-rendered.
If Laravel + Inertia + React: Apply all rules. Meta tags via @inertiaHead in Blade layout + <Head> component from @inertiajs/react in React pages. For SSR, create resources/js/ssr.jsx using createServer from @inertiajs/react/server, add ssr: 'resources/js/ssr.jsx' to Vite config, build with vite build && vite build --ssr, and run php artisan inertia:start-ssr. Use head-key attribute on meta tags to prevent duplicates between layout and page. Focus on schema-, social-, and perf- rules.
Rule Categories by Priority
| Priority | Category | Impact | Prefix |
|---|
| 1 | Core Web Vitals | CRITICAL | cwv- |
| 2 | Technical SEO | CRITICAL | tech- |
| 3 | On-Page SEO | HIGH | onpage- |
| 4 | Structured Data | HIGH | schema- |
| 5 | Performance SEO | HIGH | perf- |
| 6 | Social Sharing | HIGH | social- |
| 7 | React/SPA SEO | HIGH | spa- |
| 8 | Mobile-First | MEDIUM | mobile- |

Essential Patterns
Meta Tags (HTML)
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<title>Page Title — Site Name</title>
<meta name="description" content="Concise 150-160 character description of page content." />
<link rel="canonical" href="https://example.com/page" />
<meta property="og:title" content="Page Title" />
<meta property="og:description" content="Description for social sharing." />
<meta property="og:image" content="https://example.com/og-image.jpg" />
<meta property="og:url" content="https://example.com/page" />
<meta property="og:type" content="website" />
<meta name="twitter:card" content="summary_large_image" />
</head>
JSON-LD Structured Data
<script type="application/ld+json">
{
"@context": "https://schema.org",
"@type": "Article",
"headline": "Article Title",
"author": {
"@type": "Person",
"name": "Author Name"
},
"datePublished": "2026-03-14",
"dateModified": "2026-03-14",
"image": "https://example.com/article-image.jpg",
"publisher": {
"@type": "Organization",
"name": "Site Name",
"logo": {
"@type": "ImageObject",
"url": "https://example.com/logo.png"
}
}
}
</script>
React Meta Management (Inertia.js)
import { Head } from '@inertiajs/react'
interface Post {
title: string;
slug: string;
excerpt: string;
image: string;
}
function BlogPost({ post }: { post: Post }) {
return (
<>
<Head>
<title>{post.title} — Blog</title>
<meta head-key="description" name="description" content={post.excerpt} />
<link rel="canonical" href={`https://example.com/blog/${post.slug}`} />
<meta property="og:title" content={post.title} />
<meta property="og:description" content={post.excerpt} />
<meta property="og:image" content={post.image} />
<meta property="og:type" content="article" />
<meta name="twitter:card" content="summary_large_image" />
</Head>
<article>{/* content */}</article>
</>
)
}
Core Web Vitals Quick Checks
LCP < 2.5s Preload hero image, use fetchpriority="high"
INP < 200ms Break long tasks, yield to main thread
CLS < 0.1 Set width/height on images, reserve space for dynamic content
Image Optimization
<picture>
<source srcset="hero.avif" type="image/avif" />
<source srcset="hero.webp" type="image/webp" />
<img
src="hero.jpg"
alt="Descriptive alt text for the image"
width="1200"
height="630"
fetchpriority="high"
/>
</picture>
<img
srcset="photo-400.webp 400w, photo-800.webp 800w, photo-1200.webp 1200w"
sizes="(max-width: 600px) 400px, (max-width: 900px) 800px, 1200px"
src="photo-800.webp"
alt="Descriptive alt text"
