Sitelinks Searchbox

Google Search can expose a search box scoped to your website when it appears as a search result. This search box is powered by Google Search. However, if you wish to power this search box with your own search engine, or if you want search results also to include an associated mobile app, you can do so using structured data embedded on your website.

Search users sometimes enter the brand name or URL of a known site or app, only to do a more detailed search once they reach their destination. For example, users searching for pizza pins on Pinterest would type Pinterest or pinterest.com into Google Search—either from the Google App or from their web browser—then load the site or Android app, and finally search for pizza. The search box provides a quick way for users to search your site or app immediately on the search results page. The search box implements real-time suggestions and other features.

Example

Here is an example search result for "Pinterest" on Google that returns a sitelinks search box for the Pinterest website:

Here is some example markup that would implement a sitelinks search box that uses the website's custom search engine:

Guidelines

In addition to structured data general guidelines, these additional guidelines apply to sitelinks search box markup.

Here are the steps to set up a search box for your site or app:

Install a working search engine on your web site or Android app.
Sitelinks search queries send the user to the search results page for your site or app, so you need a functioning search engine to power this feature.
- Websites: Set up a search engine on your website or Android app. The feature forwards the user's query to your target using the syntax specified in your structured data. Your search engine should support UTF-8-encoded queries.
- Apps: See Search Overview on the Android Developer Site to learn how to implement a search engine for your app. Your Android app should support an ACTION_VIEW intent from Search results, with the corresponding data URI specified in your markup's potentialAction.target property.
Implement the WebSite structured data element on the homepage for your site. An app must have an associated website to enable this feature, even if the website is only a single page. A few additional guidelines:
- Add this markup only to the homepage, not to any other pages.
- Always specify one SearchAction for the website, and optionally another if supporting app search. You should always have a SearchAction for the website even if the app is your preferred search target; this ensures that if the user is not searching from an Android phone or does not have your Android app installed, the search result directs to your website.
Verify your structured data using the Structured Data Testing Tool.
Verify your search engine implementation by copying the WebSite.potentialAction.target URL from your structured data, replacing search_term_string with a test query, and browsing to that URL in a web browser. For example, if your website is example.com, and you want to test the query "kittens", you would browse to https://www.example.com/search/?q={kittens}.
Set a preferred canonical URL for your domain's homepage using the rel="canonical" link element on all variants of the homepage. This helps Google Search choose the correct URL for your markup. Your server must support UTF-8 character encoding.
For apps, enable the proper intent filters to support the URL you specify in the app target of your markup. For an example of how to create intent filters for Google Search urls, see Firebase App Indexing for Android.

Google Search can choose to add a sitelinks searchbox to your site even if it does not include the structured data described here. However, you can prevent this behavior by add the following meta tag to your homepage:

<meta name="google" content="nositelinkssearchbox" />

The sitelinks search box will be disabled as part of the normal Googlebot crawling and processing of the page, which can take a few weeks depending on the site and other factors.

Structured data type definitions

You must include the required properties for your content to be eligible for display as a rich result. You can also include the recommended properties to add more information about your content, which could provide a better user experience.

Modified type `WebSite`

Google Search uses a modified WebSite structured data type both for website and app search boxes. The full definition of WebSite is provided on schema.org, although Google Search deviates slightly from the standard. The description shown below is definitive.

Required properties

potentialAction

Array of one or two SearchAction objects

This object describes the URI to send the query to, and the syntax of the request that is sent. You must implement a webpage or intent handler that can receive the request, and perform an appropriate search on the submitted string. If the user is not on an Android app (or is on an Android app but has not specified an Android intent target), the search box will send the website version of the query to the location specified; if the user is on an Android device and has specified an Android intent URI, it will send that intent.

You should always create a website SearchAction to enable the desktop search case. If also supporting app search, you can additionally specify a SearchAction object for your app. Each SearchAction object has the following members:

potentialAction.@type
potentialAction.target
potentialAction.query-input

Website example

The following example sends a GET request to https://query.example.com/search?q=user%20search%20string.

"potentialAction": [{
  "@type": "SearchAction",
  "target": "https://query.example.com/search?q={search_term_string}",
  "query-input": "required name=search_term_string"
}]

App example

The following example sends an Android intent to android-app://com.example/https/query.example.com/search/?q=user_search_string.

"potentialAction": [{
  "@type": "SearchAction",
  "target": "android-app://com.example/https/query.example.com/search/?q={search_term_string}",
  "query-input": "required name=search_term_string"
}]

potentialAction.query-input

Text

Use the literal string required name = search_term_string, or whatever placeholder you used in target.

potentialAction.target

Text

A string in this format: search_handler_uri?q={search_term_string}

For example:

https://query.example.com/search?q={search_term_string}

`search_handler_uri`	For websites, the URL of the handler that should receive and handle the search query; for apps, the URI of the intent handler for your search engine that should handle queries.
`search_term_string`	A placeholder string that is replaced by user's search query when the user clicks the "Search" button in the search box.

url

URL

Specifies the URL of the site being searched. Set to the canonical homepage of your site. For example: https://www.example.org
