@power-seo/react

Declarative React components for SEO meta tag management — title templates, Open Graph, Twitter Cards, canonical URLs, robots directives, hreflang, and breadcrumbs with JSON-LD, all from a single composable API that renders directly to the DOM.

Zero third-party dependencies — only react and @power-seo/core as peers.

Why @power-seo/react?

	Without	With
Title management	❌ Ad-hoc `<title>` tags per page	✅ `<DefaultSEO>` enforces site-wide title template
Open Graph	❌ Missing or inconsistent `og:*` tags	✅ Typed `<OpenGraph>` and `<SEO openGraph={...}>`
Twitter Cards	❌ Hand-coded `twitter:*` strings	✅ Typed `<TwitterCard>` with all card types
Robots directives	❌ Raw content strings with typos	✅ Boolean and enum props — no raw string errors
Canonical URLs	❌ Omitted or duplicated	✅ `<Canonical>` and `<SEO canonical={...}>`
Hreflang	❌ Manual `<link>` tags per locale	✅ `<Hreflang>` renders all alternates + x-default
Breadcrumbs	❌ HTML nav only, no structured data	✅ `<Breadcrumb>` renders nav + BreadcrumbList JSON-LD
Framework support	❌ Locked to next-seo or react-helmet	✅ Next.js Pages Router, Vite, Gatsby, React 18/19

SSR Rendering Accuracy

Installation

npm install @power-seo/react @power-seo/core

yarn add @power-seo/react @power-seo/core

pnpm add @power-seo/react @power-seo/core

Quick Start

import { DefaultSEO, SEO } from '@power-seo/react';

function App() {
  return (
    <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>
    </DefaultSEO>
  );
}

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 get in the DOM <head>:

<title>My Post Title | My Site</title>
Correct og:image, twitter:card, and link rel="canonical" tags on every page

React SEO Components Benefit

Usage

Site-Wide Defaults with `<DefaultSEO>`

Place <DefaultSEO> once at your app root. It stores the config in React context so every nested <SEO> component can merge against it.

import { DefaultSEO } from '@power-seo/react';

function App({ children }) {
  return (
    <DefaultSEO
      titleTemplate="%s | Acme Corp"
      defaultTitle="Acme Corp"
      description="Enterprise software built for scale."
      openGraph={{
        type: 'website',
        siteName: 'Acme Corp',
        images: [{ url: 'https://acme.com/og-default.jpg', width: 1200, height: 630 }],
      }}
      twitter={{ site: '@acmecorp', cardType: 'summary_large_image' }}
    >
      {children}
    </DefaultSEO>
  );
}

Per-Page SEO with `<SEO>`

<SEO> merges the page-level config with the <DefaultSEO> context. Only provide the props that differ from the site defaults.

import { SEO } from '@power-seo/react';

function ProductPage({ product }) {
  return (
    <>
      <SEO
        title={product.name}
        description={product.summary}
        canonical={`https://acme.com/products/${product.slug}`}
        openGraph={{
          type: 'website',
          images: [{ url: product.image, width: 1200, height: 630, alt: product.name }],
        }}
      />
      <main>{/* page content */}</main>
    </>
  );
}

Robots Directives

Use the <Robots> component directly, or pass a robots object to <SEO>. All 10 standard directives are supported via typed props.

import { Robots } from '@power-seo/react';

// Noindex a staging page
<Robots index={false} follow={true} />
// → <meta name="robots" content="noindex, follow" />

// Advanced directives
<Robots
  index={true}
  follow={true}
  maxSnippet={150}
  maxImagePreview="large"
  unavailableAfter="2026-12-31T00:00:00Z"
/>
// → <meta name="robots" content="index, follow, max-snippet:150, max-image-preview:large, unavailable_after:2026-12-31T00:00:00Z" />

Use buildRobotsContent from @power-seo/core if you need the raw robots string outside a component:

import { buildRobotsContent } from '@power-seo/core';

buildRobotsContent({ index: false, follow: true, maxSnippet: 150 });
// → "noindex, follow, max-snippet:150"

Open Graph Tags

Use <OpenGraph> for standalone OG tag rendering, or pass openGraph to <SEO>.

import { OpenGraph } from '@power-seo/react';

<OpenGraph
  type="article"
  title="How to Build a React SEO Pipeline"
  description="A step-by-step guide to SEO in React applications."
  url="https://example.com/blog/react-seo"
  images={[
    { url: 'https://example.com/react-seo-og.jpg', width: 1200, height: 630, alt: 'React SEO' },
  ]}
  article={{
    publishedTime: '2026-01-15T00:00:00Z',
    authors: ['https://example.com/author/jane'],
    tags: ['react', 'seo', 'typescript'],
  }}
/>;

Twitter Cards

Use <TwitterCard> for standalone Twitter/X card tag rendering, or pass twitter to <SEO>.

import { TwitterCard } from '@power-seo/react';

<TwitterCard
  cardType="summary_large_image"
  site="@mysite"
  creator="@author"
  title="How to Build a React SEO Pipeline"
  description="A step-by-step guide to SEO in React applications."
  image="https://example.com/twitter-card.jpg"
  imageAlt="React SEO guide"
/>;

Canonical URL

import { Canonical } from '@power-seo/react';

// Absolute URL
<Canonical url="https://example.com/blog/react-seo" />

// With base URL resolution
<Canonical url="/blog/react-seo" baseUrl="https://example.com" />

Hreflang for Multi-Language Sites

import { Hreflang } from '@power-seo/react';

<Hreflang
  alternates={[
    { hrefLang: 'en', href: 'https://example.com/en/page' },
    { hrefLang: 'fr', href: 'https://example.com/fr/page' },
    { hrefLang: 'de', href: 'https://example.com/de/page' },
  ]}
  xDefault="https://example.com/en/page"
/>;

<Breadcrumb> renders both the visible <nav> element and an embedded application/ld+json BreadcrumbList script for Google rich results.

import { Breadcrumb } from '@power-seo/react';

<Breadcrumb
  items={[{ name: 'Home', url: '/' }, { name: 'Blog', url: '/blog' }, { name: 'React SEO Guide' }]}
/>;

Customize the separator and styling:

<Breadcrumb
  items={breadcrumbItems}
  separator=" › "
  className="breadcrumb-nav"
  linkClassName="breadcrumb-link"
  activeClassName="breadcrumb-active"
  includeJsonLd={true}
/>

Noindexing Entire Environments

// Noindex all staging pages with a single DefaultSEO prop
<DefaultSEO
  robots={{ index: false, follow: false }}
  titleTemplate="%s | Staging"
  defaultTitle="Staging"
>
  {children}
</DefaultSEO>

Using `renderMetaTags` and `renderLinkTags`

If you generate tag arrays via @power-seo/core utilities directly, use these helpers to convert them to React elements:

import { buildMetaTags, buildLinkTags } from '@power-seo/core';
import { renderMetaTags, renderLinkTags } from '@power-seo/react';

const metaTags = buildMetaTags({ description: 'My page', noindex: true });
const linkTags = buildLinkTags({ canonical: 'https://example.com/page' });

return (
  <>
    {renderMetaTags(metaTags)}
    {renderLinkTags(linkTags)}
  </>
);

Use Cases

Next.js Pages Router sites — per-page SEO with site-wide defaults via _app.tsx
Vite + React SPAs — manage head tags in single-page apps without a full meta framework
Gatsby sites — declarative SEO components alongside Gatsby's static rendering
SaaS marketing sites — consistent OG cards and title templates across every landing page
Blog platforms — article Open Graph with og:article:publishedTime and author tags
E-commerce listings — product canonical URLs and Twitter Cards at scale
Multi-language sites — hreflang alternate link management across locale variants
Staging environments — easily noindex entire environments with a single <DefaultSEO robots={{ index: false }} />

Architecture Overview

Pure React — no compiled binary, no native modules, no third-party head management library
Zero runtime dependencies — only react and @power-seo/core as peer dependencies
React 19 native hoisting — <title>, <meta>, and <link> elements hoist to <head> automatically in React 19; wrap with a framework Head component in React 18
Context-based defaults — <DefaultSEO> uses React.createContext so defaults flow through the tree without prop drilling
DOM-targeting — renders directly to the browser DOM (does NOT require react-helmet or react-helmet-async); for Next.js App Router use @power-seo/meta instead
Tree-shakeable — "sideEffects": false with named exports per component
Dual ESM + CJS — ships both formats via tsup for any bundler or require() usage
Full TypeScript — all component props, config types, and utility function signatures are exported
