Why SEO for Headless WordPress Is Different
Traditional WordPress SEO is straightforward: install Yoast, fill in meta fields, done. Plugins handle everything automatically.
Headless WordPress breaks this pattern.
When you decouple the frontend from WordPress, SEO plugins like Yoast and RankMath can't automatically inject meta tags into your pages. The responsibility shifts to your frontend application.
The Good News: Headless Can Improve SEO
Before we dive into challenges, understand this: headless WordPress often improves SEO rankings when done correctly.
Why Headless Helps SEO
⚡ Faster Page Speeds
- • Modern frameworks produce optimized bundles
- • Static generation eliminates server processing
- • CDN-delivered pages load instantly
📊 Better Core Web Vitals
- • Lower LCP (Largest Contentful Paint)
- • Better FID (First Input Delay)
- • Minimal CLS (Cumulative Layout Shift)
🧹 Cleaner Code
- • No bloated WordPress theme overhead
- • Precise control over what loads
- • Modern image optimization
🔒 Improved Security
- • Static frontends have no database to attack
- • Better uptime = better crawlability
Core Web Vitals: The Foundation
Google uses Core Web Vitals as a ranking factor. Headless WordPress can dramatically improve these metrics.
The Three Core Web Vitals
How Headless Bridge Helps Core Web Vitals
Traditional WordPress → WPGraphQL
API TTFB: 300-800ms
This delays LCP by the same amount
Headless Bridge
API TTFB: 50-80ms
LCP improves dramatically
Core Web Vitals Checklist
LCP Optimization
- ☐Use pre-compiled API (Headless Bridge) for sub-100ms TTFB
- ☐Preload hero images with <link rel="preload">
- ☐Use modern image formats (WebP, AVIF)
- ☐Implement responsive images with srcset
- ☐Use CDN for image delivery
- ☐Enable static site generation or ISR
FID Optimization
- ☐Minimize JavaScript bundle size
- ☐Use code splitting (automatic in Next.js/Nuxt)
- ☐Defer non-critical JavaScript
- ☐Avoid long-running JavaScript tasks
CLS Optimization
- ☐Set explicit width/height on images
- ☐Reserve space for dynamic content
- ☐Avoid inserting content above existing content
- ☐Use CSS aspect-ratio for media elements
Meta Tags: Making Yoast/RankMath Work Headless
Your SEO plugin still generates metadata—you just need to fetch and render it.
How Headless Bridge Handles SEO Metadata
Headless Bridge automatically includes SEO metadata from Yoast and RankMath:
{
"title": "My Blog Post",
"content": "...",
"seo": {
"title": "My Blog Post | Site Name",
"description": "A compelling meta description",
"canonical": "https://example.com/blog/my-post",
"robots": "index, follow",
"ogTitle": "My Blog Post",
"ogDescription": "Description for social sharing",
"ogImage": "https://example.com/og-image.jpg",
"twitterCard": "summary_large_image"
}
}Implementing in Next.js (App Router)
// app/blog/[slug]/page.tsx
export async function generateMetadata({ params }): Promise<Metadata> {
const post = await getPost(params.slug);
return {
title: post.seo?.title || post.title,
description: post.seo?.description,
openGraph: {
title: post.seo?.ogTitle || post.title,
description: post.seo?.ogDescription,
images: post.seo?.ogImage ? [post.seo.ogImage] : [],
type: 'article',
},
alternates: {
canonical: post.seo?.canonical,
},
};
}SEO Metadata Checklist
- ☐Title tag unique per page
- ☐Meta description compelling and under 160 characters
- ☐Canonical URL set correctly
- ☐Open Graph tags for social sharing
- ☐Twitter Card tags
- ☐Robots meta tag (index/noindex)
- ☐Author information for articles
Sitemaps: Helping Google Find Your Content
Headless sites need to generate sitemaps dynamically or at build time.
Approach 1: Generate at Build Time
Most frameworks have sitemap plugins:
// next-sitemap.config.js
module.exports = {
siteUrl: 'https://example.com',
generateRobotsTxt: true,
additionalPaths: async (config) => {
const posts = await getPosts();
return posts.map(post => ({
loc: `${config.siteUrl}/blog/${post.slug}`,
lastmod: post.modifiedAt,
changefreq: 'weekly',
priority: 0.7,
}));
},
};Sitemap Checklist
- ☐Sitemap includes all public pages
- ☐Sitemap uses correct URLs (no localhost, no drafts)
- ☐lastmod dates are accurate
- ☐Sitemap submitted to Google Search Console
- ☐robots.txt references sitemap location
Structured Data (Schema.org)
Structured data helps Google understand your content and can enable rich results.
Common Schema Types for WordPress Content
Implementing JSON-LD
// Using schema from API
export default function BlogPost({ post }) {
return (
<>
{post.seo?.schema && (
<script
type="application/ld+json"
dangerouslySetInnerHTML={{
__html: JSON.stringify(post.seo.schema)
}}
/>
)}
<article>...</article>
</>
);
}Structured Data Checklist
- ☐JSON-LD added to all content pages
- ☐Schema validated with Google's Rich Results Test
- ☐No errors in Search Console structured data report
- ☐Article schema for blog posts
- ☐BreadcrumbList for navigation
- ☐Organization schema on about/home page
Common SEO Mistakes in Headless WordPress
1. JavaScript Rendering Issues
Problem: Content rendered only client-side may not be indexed properly.
Solution: Use SSR (Server-Side Rendering) or SSG (Static Site Generation). Never render important content only on the client.
2. Missing Meta Tags
Problem: Forgetting to implement meta tags from WordPress SEO plugins.
Solution: Always fetch and render post.seo data. Create a reusable SEO component.
3. Broken Canonical URLs
Problem: Canonical URLs pointing to WordPress backend instead of frontend.
Solution: Configure Yoast/RankMath to use your frontend domain, or transform URLs in your frontend.
4. Slow API Responses
Problem: Using WPGraphQL without caching, causing slow page loads.
Solution: Use Headless Bridge for sub-100ms responses, or implement aggressive caching.
5. Missing Sitemap
Problem: No sitemap generated, or sitemap uses wrong domain.
Solution: Generate sitemap at build time with correct frontend URLs.
6. Duplicate Content
Problem: Content accessible on both WordPress and frontend domains.
Solution: Block WordPress frontend from indexing (robots.txt) or redirect to headless frontend.
