Note on app directory

This note is only relevant if using the app directory.

For standard meta data (eg: , ) then it is highly recommended that you use the built in generateMetaData method. You can check out the docs here

For JSON-LD then the only change needed is you should add useAppDir={true} to the JSON-LD component in use. You should add use this component in your page.js and NOT your head.js.

<ArticleJsonLd
  useAppDir={true}
  url="https://example.com/article"
  title="Article headline" <- required for app directory
  />

If you are using pages directory then NextSeo is exactly what you need for your SEO needs!

Usage

NextSeo works by including it on pages where you would like SEO attributes to be added. Once included on the page you pass it a configuration object with the page's SEO properties. This can be dynamically generated at a page level or in some cases your API may return an SEO object.

Setup

First, install it:

npm install next-seo

yarn add next-seo

Add SEO to Page

Using Next.js app directory introduced in Next.js 13?

If you are using Next.js app directory then it is highly recommended that you use the built in generateMetaData method. You can check out the docs here

If you are using pages directory then NextSeo is exactly what you need for your SEO needs!

Then you need to import NextSeo and add the desired properties. This will render out the tags in the <head> for SEO. At a bare minimum, you should add a title and description.

Example with just title and description:

import { NextSeo } from 'next-seo';

const Page = () => (
  <>
    <NextSeo
      title="Simple Usage Example"
      description="A short description goes here."
    />
    <p>Simple Usage</p>
  </>
);

export default Page;

But NextSeo gives you many more options that you can add. See below for a typical example of a page.

Typical page example:

import { NextSeo } from 'next-seo';

const Page = () => (
  <>
    <NextSeo
      title="Using More of Config"
      description="This example uses more of the available config options."
      canonical="https://www.canonical.ie/"
      openGraph={{
        url: 'https://www.url.ie/a',
        title: 'Open Graph Title',
        description: 'Open Graph Description',
        images: [
          {
            url: 'https://www.example.ie/og-image-01.jpg',
            width: 800,
            height: 600,
            alt: 'Og Image Alt',
            type: 'image/jpeg',
          },
          {
            url: 'https://www.example.ie/og-image-02.jpg',
            width: 900,
            height: 800,
            alt: 'Og Image Alt Second',
            type: 'image/jpeg',
          },
          { url: 'https://www.example.ie/og-image-03.jpg' },
          { url: 'https://www.example.ie/og-image-04.jpg' },
        ],
        siteName: 'SiteName',
      }}
      twitter={{
        handle: '@handle',
        site: '@site',
        cardType: 'summary_large_image',
      }}
    />
    <p>SEO Added to Page</p>
  </>
);

export default Page;

A note on Twitter Tags

Props cardType, site, handle are equivalent to twitter:card, twitter:site, twitter:creator. Documentation can be found here.

Twitter will read the og:title, og:image and og:description tags for their card. next-seo omits twitter:title, twitter:image and twitter:description to avoid duplication.

Some tools may report this an error. See Issue #14

Default SEO Configuration

NextSeo enables you to set some default SEO properties that will appear on all pages without needing to include anything on them. You can also override these on a page by page basis if needed.

To achieve this, you will need to create a custom <App>. In your pages directory create a new file, _app.js. See the Next.js docs here for more info on a custom <App>.

Within this file you will need to import DefaultSeo from next-seo and pass it props.

Here is a typical example:

import App, { Container } from 'next/app';
import { DefaultSeo } from 'next-seo';

// import your default seo configuration
import SEO from '../next-seo.config';

export default class MyApp extends App {
  render() {
    const { Component, pageProps } = this.props;
    return (
      <Container>
        <DefaultSeo
          openGraph={{
            type: 'website',
            locale: 'en_IE',
            url: 'https://www.url.ie/',
            siteName: 'SiteName',
          }}
          twitter={{
            handle: '@handle',
            site: '@site',
            cardType: 'summary_large_image',
          }}
        />
        <Component {...pageProps} />
      </Container>
    );
  }
}

To work properly, DefaultSeo should be placed above (before) Component due to behavior of Next.js internals.

Alternatively, you can also create a config file to store default values such as next-seo.config.js

export default {
  openGraph: {
    type: 'website',
    locale: 'en_IE',
    url: 'https://www.url.ie/',
    siteName: 'SiteName',
  },
  twitter: {
    handle: '@handle',
    site: '@site',
    cardType: 'summary_large_image',
  },
};

import { DefaultSeoProps } from 'next-seo';

const config: DefaultSeoProps = {
  openGraph: {
    type: 'website',
    locale: 'en_IE',
    url: 'https://www.url.ie/',
    siteName: 'SiteName',
  },
  twitter: {
    handle: '@handle',
    site: '@site',
    cardType: 'summary_large_image',
  },
};

export default config;

import at the top of _app.js

import SEO from '../next-seo.config';

and the DefaultSeo component can be used like this instead

<DefaultSeo {...SEO} />

From now on all of your pages will have the defaults above applied.

Note that Container is deprecated in Next.js v9.0.4 so you should replace that component here with React.Fragment on this version and later - see here

Title Template

Replaces %s with your title string

title = 'This is my title';
titleTemplate = 'Next SEO | %s';
// outputs: Next SEO | This is my title

title = 'This is my title';
titleTemplate = '%s | Next SEO';
// outputs: This is my title | Next SEO

Default Title

title = undefined;
titleTemplate = 'Next SEO | %s';
defaultTitle = 'Next SEO';
// outputs: Next SEO

No Index

Setting this to true will set noindex,follow (to set nofollow, please refer to nofollow). This works on a page by page basis. This property works in tandem with the nofollow property and together they populate the robots meta tag.

Note: The noindex and the nofollow properties are a little different than all the others in the sense that setting them as a default does not work as expected. This is due to the fact Next SEO already has a default of index,follow because next-seo is a SEO plugin after all. So if you want to globally these properties, please see dangerouslySetAllPagesToNoIndex and dangerouslySetAllPagesToNoFollow.

Example No Index on a single page:

If you have a single page that you want no indexed you can achieve this by:

import { NextSeo } from 'next-seo';

const Page = () => (
  <>
    <NextSeo noindex={true} />
    <p>This page is no indexed</p>
  </>
);

export default Page;

/*
<meta name="robots" content="noindex,follow">
*/

dangerouslySetAllPagesToNoIndex

It has the prefix of dangerously because it will noindex all pages. As this is an SEO plugin, that is kinda dangerous action. It is not bad to use this, just please be sure you want to noindex EVERY page. You can still override this at a page level if you have a use case to index a page. This can be done by setting noindex: false.

The only way to unset this, is by removing the prop from the DefaultSeo in your custom <App>.

No Follow

Setting this to true will set index,nofollow (to set noindex, please refer to noindex). This works on a page by page basis. This property works in tandem with the noindex property and together they populate the robots meta tag.

Note: Unlike for the other properties, setting noindex and nofollow by default does not work as expected. This is because Next SEO has a default of index,follow, since next-seo is an SEO plugin after all. If you want to globally allow these properties, see dangerouslySetAllPagesToNoIndex and dangerouslySetAllPagesToNoFollow.

Example No Follow on a single page:

If you have a single page that you want no indexed you can achieve this by:

import { NextSeo } from 'next-seo';

const Page = () => (
  <>
    <NextSeo nofollow={true} />
    <p>This page is not followed</p>
  </>
);

export default Page;

/*
<meta name="robots" content="index,nofollow">
*/

dangerouslySetAllPagesToNoFollow

It has the prefix of dangerously because it will nofollow all pages. As this is an SEO plugin, that is kinda dangerous action. It is not bad to use this, just please be sure you want to nofollow EVERY page. You can still override this at a page level if you have a use case to follow a page. This can be done by setting nofollow: false.

The only way to unset this, is by removing the prop from the DefaultSeo in your custom <App>.

| noindex | nofollow | meta content of robots | | --------- | ---------- | -------------------------- | | -- | -- | index,follow (default) | | false | false | index,follow | | true | -- | noindex,follow | | true | false | noindex,follow | | -- | true | index,nofollow | | false | true | index,nofollow | | true | true | noindex,nofollow |

robotsProps

In addition to index, follow the robots meta tag accepts more properties to archive a more accurate crawling and serve better snippets for SEO bots that crawl your page.

Example:

import { NextSeo } from 'next-seo';

const Page = () => (
  <>
    <NextSeo
      robotsProps={{
        nosnippet: true,
        notranslate: true,
        noimageindex: true,
        noarchive: true,
        maxSnippet: -1,
        maxImagePreview: 'none',
        maxVideoPreview: -1,
      }}
    />
    <p>Additional robots props in Next-SEO!!</p>
  </>
);

export default Page;

/*
<meta name="robots" content="index,follow,nosnippet,max-snippet:-1,max-image-preview:none,noarchive,noimageindex,max-video-preview:-1,notranslate">
*/

Available properties

| Property | Type | Description | | ------------------- | ------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | noarchive | boolean | Do not show a cached link in search results. | | nosnippet | boolean | Do not show a text snippet or video preview in the search results for this page. | | max-snippet | number | Use a maximum of [number] characters as a textual snippet for this search result. Read more | | max-image-preview | 'none','standard','large' | Set the maximum size of an image preview for this page in a search results. | | max-video-preview | number | Use a maximum of [number] seconds as a video snippet for videos on this page in search results. Read more | | notranslate | boolean | Do not offer translation of this page in search results. | | noimageindex | boolean | Do not index images on this page. | | unavailable_after | string | Do not show this page in search results after the specified date/time. The date/time must be specified in a widely adopted format including, but not limited to RFC 822, RFC 850, and ISO 8601. |

Twitter

Twitter will read the og:title, og:image and og:description tags for their card, this is why next-seo omits twitter:title, twitter:image and twitter:description so not to duplicate.

Some tools may report this an error. See Issue #14

facebook

facebook={{
  appId: '1234567890',
}}

Add this to your SEO config to include the fb:app_id meta if you need to enable Facebook insights for your site. Information regarding this can be found in facebook's documentation

Canonical URL

Add this on a page per page basis when you want to consolidate duplicate URLs.

canonical = 'https://www.canonical.ie/';

Alternate

This link relation is used to indicate a relation between a desktop and a mobile website to search engines.

Example:

mobileAlternate={{
  media: 'only screen and (max-width: 640px)',
  href: 'https://m.canonical.ie',
}}

languageAlternates={[{
  hrefLang: 'de-AT',
  href: 'https://www.canonical.ie/de',
}]}

Additional Meta Tags

This allows you to add any other meta tags that are not covered in the config and should be used instead of children prop.

content is required. Then either name, property or httpEquiv. (Only one on each)

Example:

additionalMetaTags={[{
  property: 'dc:creator',
  content: 'Jane Doe'
}, {
  name: 'application-name',
  content: 'NextSeo'
}, {
  httpEquiv: 'x-ua-compatible',
  content: 'IE=edge; chrome=1'
}]}

Invalid Examples:

These are invalid as they contain more than one of name, property and httpEquiv on the same entry.

additionalMetaTags={[{
  property: 'dc:creator',
  name: 'dc:creator',
  content: 'Jane Doe'
}, {
  property: 'application-name',
  httpEquiv: 'application-name',
  content: 'NextSeo'
}]}

One thing to note on this is that it currently only supports unique tags, unless you use the keyOverride prop to provide a unique key to each additional meta tag.

The default behaviour (without a keyOverride prop) is to render one tag per unique name / property / httpEquiv. The last one defined will be rendered.

For example if you pass 2 tags with the same property:

additionalMetaTags={[{
  property: 'dc:creator',
  content: 'Joe Bloggs'
}, {
  property: 'dc:creator',
  content: 'Jane Doe'
}]}

it will result in this being rendered:

<meta property="dc:creator" content="Jane Doe" />

Providing an additional keyOverride property like this:

additionalMetaTags={[{
  property: 'dc:creator',
  content: 'Joe Bloggs',
  keyOverride: 'creator1',
}, {
  property: 'dc:creator',
  content: 'Jane Doe',
  keyOverride: 'creator2',
}]}

results in the correct HTML being rendered:

<meta property="dc:creator" content="Joe Bloggs" />
<meta property="dc:creator" content="Jane Doe" />

Additional Link Tags

This allows you to add any other link tags that are not covered in the config.

rel and href is required.

Example:

additionalLinkTags={[
  {
    rel: 'icon',
    href: 'https://www.test.ie/favicon.ico',
  },
  {
    rel: 'apple-touch-icon',
    href: 'https://www.test.ie/touch-icon-ipad.jpg',
    sizes: '76x76'
  },
  {
    rel: 'manifest',
    href: '/manifest.json'
  },
  {
    rel: 'preload',
    href: 'https://www.test.ie/font/sample-font.woof2',
    as: 'font',
    type: 'font/woff2',
    crossOrigin: 'anonymous'
  }
]}

it will result in this being rendered:

<link rel="icon" href="https://www.test.ie/favicon.ico" />
<link
  rel="apple-touch-icon"
  href="https://www.test.ie/touch-icon-ipad.jpg"
  sizes="76x76"
/>
<link rel="manifest" href="/manifest.json" />
<link
  rel="preload"
  href="https://www.test.ie/font/sample-font.woof2"
  as="font"
  type="font/woff2"
  crossorigin="anonymous"
/>

JSON-LD

Next SEO now has the ability to set JSON-LD a form of structured data. Structured data is a standardised format for providing information about a page and classifying the page content.

Google has excellent content on JSON-LD -> HERE

If using app directory then please ensure to add useAppDir={true} prop and that you are using the component in the page.js

Below you will find a very basic page implementing each of the available JSON-LD types:

Pull request very welcome to add any from the list found on here

JSON-LD Security

Just a quick note on security. To get JSON-LD onto the page it needs to be in a script tag. next-seo achieves this by using a script tag with dangerouslySetInnerHTML.

So if passing anything directly from a URL to one of the components below please ensure you sanitize it first if needed.

View toJson.tsx for implementation detail.

Handling multiple instances

If your page requires multiple instances of a given JSON-LD component, you can specify unique keyOverride properties, and next-seo will handle the rest.

This comes in handy for blog rolls, search results, and overview pages.

Please fully research when you should and shouldn't add multiple instances of JSON-LD.

<ExampleJsonLd keyOverride="my-new-key" />
