To get started, install the plugin using npm:
```sh
npm install sanity-plugin-seo
```
Add it as a plugin in `sanity.config.ts` (or .js):
```ts
import { defineConfig } from "sanity";
import { seoMetaFields } from "sanity-plugin-seo";
export default defineConfig({
plugins: [seoMetaFields()],
});
```
You can then add the `schemaMarkup` field to any Sanity Document you want it to be in.
```javascript
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",
};
},
},
};
```
Create query for SEO fields in `/lib/sanity/queries/demo.ts` frontend (Typescript or Javascript)
```Typescript
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)
``` 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)
```Typescript (or js)

}
return values as NextSeoOpenGraph
}
export const getMetaObjects = (tags: MetaTagType[], allowIndexing?: boolean) => {

tags.map(tag => {

})
return obj as unknown as NextSeoMetaTag
}
interface CustomNextSeoProps {

const tags = useMemo(

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