📦 Installation

To get started, install the plugin using npm:

npm install sanity-plugin-seo

📋 Usage in Sanity Studio

Add it as a plugin in sanity.config.ts (or .js):

import { defineConfig } from "sanity";
import { seoMetaFields } from "sanity-plugin-seo";

export default defineConfig({
  plugins: [seoMetaFields()],
});

You can then add the seoMetaFields field type to any Sanity document schema.

const myDocument = {
  type: "page",
  name: "page",
  fields: [
    {
      title: "Seo",
      name: "seo",
      type: "seoMetaFields",
    },
  ],
  preview: {
    select: {
      metaTitle: "seo",
    },
    prepare(selection) {
      const { metaTitle } = selection?.metaTitle || "";
      return {
        title: metaTitle || "seo",
      };
    },
  },
};

⚛️ Usage with Next.js and React.js

Create query for SEO fields in /lib/sanity/queries/demo.ts frontend (Typescript or Javascript)

const groqQuery = groq`*[_type == "page"]{
_type,
"slug":slug.current,
${seo},
}`;

export const seo = /* groq */ `seo{
${seofields}
}`;

export const seofields = /* groq */ `
_type,
metaTitle,
nofollowAttributes,
seoKeywords,
metaDescription,
openGraph{
${openGraphQuery}
},
twitter{
${twitterQuery}
},
additionalMetaTags[]{
_type,
metaAttributes[]{
${metaAttributesQuery}
}
}
`;

export const twitterQuery = /* groq */ `
_type,
site,
creator,
cardType,
handle
`;

export const openGraphQuery = /* groq */ `
_type,
siteName,
url,
description,
title,
image{
${imageFields}
}
`;

export const metaAttributesQuery = /* groq */ `
_type,
attributeValueString,
attributeType,
attributeKey,
attributeValueImage{
${imageFields}
}
`;

export const imageFields = /* groq */ `
_type,
crop{
_type,
right,
top,
left,
bottom
},
hotspot{
_type,
x,
y,
height,
width,
},
asset->{...}
`;

Create type for all the fields /lib/sanity/queries/demo.d.ts (Typescript)

export type SeoType = {
  _type?: "seo";
  nofollowAttributes?: boolean
  metaDescription?: string;
  additionalMetaTags?: MetaTagType[];
  metaTitle?: string;
  seoKeywords?: string[]
  openGraph?: OpenGraphType;
  twitter?: Twitter;
};

export type MetaTagType = {
  _type: "metaTag";
  metaAttributes?: MetaAttributeType[];
};

export type MetaAttributeType = {
  _type: "metaAttribute";
  attributeKey?: string;
  attributeType?: string;
  attributeValueString?: string;
  attributeValueImage?: CustomImageType;
};


export type OpenGraphType = {
  _type: "openGraph";
  title: string;
  url?: string
  siteName?: string
  description: string;
  image: CustomImageType;
};

export type Twitter = {
  _type: "twitter";
  handle?: string;
  creator?: string
  site?: string;
  cardType?: string;
};

export type CustomImageType = {
  _type: "customImage";
  asset?: SanityImageAssetType;
  crop?: {
    _type: "SanityImageCrop";
    right: number;
    top: number;
    left: number;
    bottom: number;
  };
  hotspot?: {
    x: number;
    y: number;
    height: number;
    _type: "SanityImageHotspot";
    width?: number;
  };
};

export type SanityImageAssetType = {
  _type?: "SanityImageAsset";
  _id?: string;
  path?: string;
  url?: string;
  metadata?: {
    _type?: "SanityImageMetadata";
    dimensions?: {
      _type?: "SanityImageDimensions";
      height?: number;
      width?: number;
    };
  };
};

Call MetaData on CustomNextSeo (Typescript or Javascript)

import React, { useMemo } from "react";
import type { PropsWithChildren } from "react";
import { NextSeo } from "next-seo";
import { MetaTag as NextSeoMetaTag, OpenGraph as NextSeoOpenGraph } from 'next-seo/lib/types'

    description,
    siteName,
    url,
    title,
    images: [{ url: getImage ?? '' }],
  }
  return values as NextSeoOpenGraph
}

export const getMetaObjects = (tags: MetaTagType[], allowIndexing?: boolean) => {
  const tagArray: NextSeoMetaTag[] = []
  tags.map(tag => {
    const excludeTag =
      !allowIndexing &&
      !!tag.metaAttributes?.find(
        i =>
          i?.attributeValueString?.includes('noindex') ||
          i?.attributeValueString?.includes('nofollow'),
      )
    if (!excludeTag) {
      const metaTag = getMetaAttribute(tag?.metaAttributes)
      if (metaTag) {
        tagArray.push(metaTag)
      }
    }
  })
  return tagArray
}

export const resolveImage = (image?: CustomImageType) => {
  return image?.asset?.url ?? "";
};

export const getMetaAttribute = (attrs: MetaAttributeType[] | undefined) => {

  const obj: Record<string, string> = {}

    Object.assign(obj, {
      [i?.attributeKey as string]:
        i.attributeType == "image"
          ? resolveImage(i?.attributeValueImage)
          : i.attributeValueString,
    })
  })
  return obj as unknown as NextSeoMetaTag
}


interface CustomNextSeoProps {
  seo: SeoType | null;
  slug: string;
}

const CustomNextSeo: React.FC<PropsWithChildren<CustomNextSeoProps>> = ({
  seo,
    children,

  const { additionalMetaTags, metaDescription, metaTitle, twitter, nofollowAttributes, seoKeywords } = seo || {};

  const tags = useMemo(
    () => (additionalMetaTags ? getMetaObjects(additionalMetaTags) : []),
    [additionalMetaTags]
  );
  const openGraph = useMemo(
    () => (seo?.openGraph ? getOpenGraph(seo?.openGraph) : undefined),
    [seo]
  );
  const url = (process.env.NEXT_PUBLIC_APP_URL ?? "") + (slug?.startsWith("/") ? slug : `/${slug}`);

  return (
       <>
    <NextSeo
      themeColor=""
      twitter={{
        handle: twitter?.creator,
        site: twitter?.site,
        cardType: twitter?.cardType,
      }}
      nofollow={nofollowAttributes}
      noindex={nofollowAttributes}
      openGraph={openGraph}
      canonical={url || ""}
      additionalMetaTags={((seoKeywords && seoKeywords?.length > 0
        ? [{ name: "keywords", content: seoKeywords?.join(", ") }]
