Overview
@power-seo/react is a complete set of declarative React components for SEO meta tag management for Next.js Pages Router, Vite, Gatsby, and any React application that renders to the DOM, helping you manage titles, Open Graph, Twitter Cards, canonical URLs, robots directives, hreflang, and breadcrumbs from a single composable API.
What it does
- ✅ All-in-one
<SEO> component — renders title, meta description, canonical, robots, Open Graph, and Twitter Card from one component
- ✅ Context-based defaults —
<DefaultSEO> at app root sets site-wide defaults; pages override selectively
- ✅ Full robots directive support — all 10 directives including
noindex, noarchive, max-snippet, max-image-preview, unavailable_after
- ✅ Hreflang internationalization —
<Hreflang> renders <link rel="alternate"> tags for multi-language sites
- ✅ Breadcrumbs with JSON-LD —
<Breadcrumb> renders visible nav plus embedded BreadcrumbList structured data
What it is not
- ❌ Not an App Router solution — use
@power-seo/meta for Next.js App Router generateMetadata()
- ❌ Not server-side only — requires
react-helmet-async under the hood; targets DOM-rendering React apps
Recommended for
- Next.js Pages Router apps, Vite + React SPAs, Gatsby sites, and Create React App projects
Why @power-seo/react Matters
The problem
- Scattered meta tag management — teams add
<Helmet> blocks inconsistently across hundreds of components
- Missing Open Graph images — no single source of truth for default OG images leads to bare link previews
- Incorrect robots directives — hand-crafted
content strings omit valid directives or include typos
Why developers care
- SEO: Consistent title templates and canonical URLs prevent duplicate content penalties
- UX: Correct OG and Twitter Card images dramatically increase social click-through
- Performance: Centralized
<DefaultSEO> prevents redundant meta tag renders on every page
Key Features
<SEO> all-in-one component — renders title, meta description, canonical, robots, Open Graph, and Twitter Card tags from a single component
<DefaultSEO> context-based defaults — set site-wide title template, default OG image, and global robots directives; individual pages override selectively
<Robots> full directive support — all 10 robots directives including noindex, nofollow, noarchive, nosnippet, noimageindex, notranslate, max-snippet, max-image-preview, max-video-preview, unavailable_after
<OpenGraph> all OG properties — og:title, og:description, og:type, og:url, og:image (with width/height/alt), og:site_name, og:locale, og:article:* properties
<TwitterCard> all card types — summary, summary_large_image, app, player; with site, creator, title, description, image
<Canonical> link tag — renders <link rel="canonical"> with proper href
<Hreflang> i18n alternate links — renders <link rel="alternate" hreflang="..."> tags for multi-language sites including x-default
<Breadcrumb> with JSON-LD — renders visible breadcrumb navigation plus embedded application/ld+json BreadcrumbList
- TypeScript-first — full
.d.ts declarations, all props fully typed
- Tree-shakeable — import only the components you use
Benefits of Using @power-seo/react
- Improved consistency:
<DefaultSEO> enforces site-wide title templates and OG defaults with zero duplication
- Better social visibility: Correct
<TwitterCard> and <OpenGraph> images increase social click-through rates
- Safer SEO implementation: Typed robots directive props prevent typos that could accidentally noindex pages
- Faster delivery: Drop-in components eliminate boilerplate meta tag code from every page component
Quick Start
import { HelmetProvider } from 'react-helmet-async';
import { DefaultSEO, SEO } from '@power-seo/react';
function App() {
return (
<HelmetProvider>
<DefaultSEO
titleTemplate="%s | My Site"
defaultTitle="My Site"
description="The best site on the internet."
openGraph={{ type: 'website', siteName: 'My Site' }}
twitter={{ site: '@mysite', cardType: 'summary_large_image' }}
/>
<Router>
<Routes />
</Router>
</HelmetProvider>
);
}
function BlogPage({ post }) {
return (
<>
<SEO
title={post.title}
description={post.excerpt}
canonical={`https://example.com/blog/${post.slug}`}
openGraph={{
type: 'article',
images: [{ url: post.coverImage, width: 1200, height: 630, alt: post.title }],
}}
/>
<article>{/* content */}</article>
</>
);
}
What you should see
<title>My Post Title | My Site</title> in the DOM <head>
- Correct
og:image, twitter:card, and link rel="canonical" tags on every page
Installation
npm i @power-seo/react
yarn add @power-seo/react
pnpm add @power-seo/react
bun add @power-seo/react
Peer dependencies:
npm install react react-dom react-helmet-async
Note: Wrap your app in <HelmetProvider> from react-helmet-async.
Framework Compatibility
Supported
- ✅ Next.js Pages Router — works with
_app.tsx and per-page <SEO> components
- ✅ Vite + React — works in standard SPA setup
- ✅ Gatsby — works with
gatsby-plugin-react-helmet or standalone
- ✅ Create React App — works out of the box
Environment notes
- SSR/SSG: Supported via
react-helmet-async (SSR-safe)
- Edge runtime: Not supported (requires DOM/React reconciler)
- Next.js App Router: Not recommended — use
@power-seo/meta instead for App Router
Use Cases
- Next.js Pages Router sites — per-page SEO with site-wide defaults
- SaaS marketing sites — consistent OG cards for every landing page
- Blog platforms — article Open Graph with
og:article:publishedTime and author data
- E-commerce listings — product pages with correct canonical and Twitter Cards
- Multi-language sites — hreflang alternate link management across locale variants
- Staging environments — easily
noindex entire environments with a single <DefaultSEO robots={{ index: false }} />
- Breadcrumb navigation — visible breadcrumbs with embedded JSON-LD for Google rich results
Example (Before / After)
Before:
- Each page has a different <Helmet> implementation with inconsistent OG formats
- Some pages missing canonical, some missing twitter:card
- Robots directives hand-coded as raw strings with typos
After (@power-seo/react):
- <DefaultSEO> enforces site-wide title template and default OG image
- <SEO> on each page overrides only what differs — canonical, OG image, article properties
- <Robots> accepts typed boolean props — no raw content string typos
Implementation Best Practices
- Always use
<HelmetProvider> at the root — required for SSR and correct head management
- Set
<DefaultSEO> once at the app root — every page inherits defaults without re-declaring
- Use
noindex={true} on <SEO> for staging, admin, and private pages — not in next.config.js redirects
- Always set
canonical on pages with query parameters to prevent duplicate content
- Include
x-default in <Hreflang> to signal the default language for international visitors
Architecture Overview
Where it runs
- Client-side (CSR):
react-helmet-async manages <head> updates on navigation
- Server-side (SSR):
HelmetProvider collects head tags during render and serializes them into the initial HTML
- CI/CD: No direct CI integration — audit head tags with
@power-seo/audit
Data flow
- Input: Page-level title, description, OG config, robots directive props
- Analysis:
react-helmet-async merges <DefaultSEO> defaults with <SEO> overrides
- Output: Rendered
<head> tags: <title>, <meta>, <link>, <script> (JSON-LD for breadcrumbs)
- Action: Correct head tags for crawlers, social scrapers, and browser tab display
