Bring SEO insights into Sanity.

SEO Tools for Sanity


When proposing backend solutions for a client website many will request something like WordPress as this is a system they are familiar with. One of the tools that is available for WordPress is Yoast to give the user feedback on the SEO of the current page. This plugin can bring those insights into Sanity for your clients so you can finally start developing those projects with Sanity. (it is powered by YoastSEO.js)

How to use

  1. Install the plugin using the Sanity CLI sanity install seo-tools
  2. Configure your document with the SEO tools. The result of the content(doc) function should represent the final result of (??) but does not have to be 100% accurate. It should act as a real-time representation of the resulting content
export default {
    type: 'document',
    name: '...',
    title: '...',
    fields: [{
        name: 'seo',
        title: 'SEO',
        type: 'seo-tools', // use seo-tools type
        options: {
            baseUrl: 'https://.../', // (REQUIRED) This is the baseUrl for your site
            baseUrl(doc) {
                return 'https://.../'; // for dynamic baseUrls
            slug(doc) { // (REQUIRED) a function to return the slug of the current page, which will be appended to the baseUrl
                return doc.slug.current;
            fetchRemote: true, // Can be set to false to disable fetching the remote source (you will need to pass the content helpers for analysis)
            content(doc) {
                return 'simple html representation of your doc'; // (OPTIONAL) If your site is generated after Sanity content updates you can use this for better real time feedback
            title(doc) {
                return 'page title'; // (OPTIONAL) return page title otherwise inferred from scrape
            description(doc) {
                return 'page description'; // (OPTIONAL) return page description otherwise inferred from scrape
            locale(doc) {
                return 'page locale'; // (OPTIONAL) return page locale otherwise inferred from scrape
            contentSelector: 'body' // (OPTIONAL) option to finetune where Yoast will look for the content. (only applicable for scraping without content function)
  1. Make sure to enable CORS for the Sanity domain otherwise the plugin won't be able to fetch your content.
  2. (OPTIONAL) You can add a file called seo-tools.json in your studio's config folder. Following options can be set:
    "focus_keyword_required": false, // makes the focus_keyword field required
    "focus_synonyms_required": false, // makes the focus_synonyms field required
    "seo_title_required": false, // makes the seo_title field required
    "meta_description_required": false // makes the meta_description field required

Available parts for implementation


It is possible to implement this studio part (The Parts System) to customize the object schema provided by the seo-tools plugin.

To do this you will need to add an implementation to your studio's sanity.json:

    "parts": [
        "implements": "part:sanity-plugin-seo-tools/schema-customizer",
        "path": "./schemaCustomizer.js"

And implement the schemaCustomizer.js file; eg:

export default (schema) => {
        name: 'my_field',
        title: 'My field',
        type: 'string',
    return schema;

Common issues


The plugin will try to load your {baseUrl}/{slug} URL, but this is most likely blocked by CORS because we need to fetch it from the browser. There are 2 ways to solve it

  1. Allow CORS from your Sanity studio domain
  2. Disable fetchRemote altogether and provide all methods manually

Can't resolve "config:seo-tools"

In v1.1.0 we added a config file. To get rid of this error when upgrading an instance simply add a file called seo-tools.json to your config folder and set it to an empty object {}.

Install command

sanity install seo-tools
