Bringing the Power of Knowledge Graph to Custom Search

We're happy to announce that Custom Search Engine (CSE) owners can now use Knowledge Graph entities to configure their CSE.  The Knowledge Graph (KG) is used by Google Search to help users discover information more quickly and easily, and contains millions of entries that describe real-world entities like people, places, and things.

CSE owners can use KG Entities to

  • Define which pages the CSE searches
  • Create Refinements to narrow down search results within a CSE.

For more information about using Knowledge Graph Entities to define and refine your Custom Search Engine, visit our developer documentation.

Here are some examples of what you can do:

Searching the entire web for specific Entities

CSE's KG Entity support makes it easy to search the entire web for pages (or images) about specific topics.
We've configured this CSE to search the entire web for pages about Alphabet companies, using the CSE control panel as shown below:

Searching specific pages for Entities

Instead of searching the entire web, you can combine KG entities with CSE's existing site search functionality.
For example, we've configured this CSE to search Wikipedia for pages about the entity Pittsburgh:

Defining Refinements with Entities

CSE's refinements feature allows users to drill down into their search results. Now, CSE owners can use KG entities to define the refinements if their CSE.

For example, we defined this CSE to be about the Knowledge Graph Entity "basketball":

Then we add refinements for basketball subtopics, like the NBA, WNBA, College, Olympic basketball, and basketball gear.  For example, this refinement returns pages that are about both Basketball (from the top-level CSE definition) and Sports Equipment, Shoes, or Jerseys:

Introducing Callbacks for even more rendering control

For our power users that are interested in customizing the rendering of search results beyond what is possible through our standard controls in the Custom Search Engine control panel, we are introducing a new set of Callback functions that will unlock new capabilities to customize your search result rendering even further.

Callbacks provide an opportunity to customize the experience during the rendering flow of the search results in powerful new ways. We are introducing callbacks for when the search begins, when the results are ready, and when the results are rendered. If you would like to augment your results with additional information or increased interactivity, callbacks provide an easy way to build on top of the already existing customizations you have for Custom Search Engine.

Please note that this feature only applies to the Custom Search Element API of the Custom Search Engine. These Callbacks are not applicable to the JSON API of the Custom Search Engine. Also, these callbacks only modify the organic search results; they do not modify any of the advertising or the rendering of the advertising returned from the Custom Search Element API.

Learn how to use these new functions in the Search Callbacks section of the Custom Search Element API for more details.

We are excited to see what new customizations our vibrant and creative publisher ecosystem will bring to Customized Search Engines with these new callbacks.

We would like to hear your feedback and comments on this new functionality. We invite you to share your thoughts in our user forum.

Improving our mobile layout

We are pleased to announce a new mobile layout that should provide an improved experience for mobile device users. We’ve changed the look of the search box and refinements, increased the size of the thumbnails, and simplified the pagination.
Before                                                                                  After
Most of these changes only affect mobile devices, but the refinements have also been updated for desktop.
Before                                                                                  After
The mobile-specific changes can be optionally disabled by setting the "mobileLayout" attribute of the search element to “disabled”.

Expanding our Custom Search Engine offerings.

We are excited to announce an expansion of our Custom Search Engine offerings. We offer the following implementation options for Custom Search Engine.
  • Standard Search Element - This free, ads supported search element is easily added to your site with simple javascript, is available for everyone, and has no daily query limit.
  • Nonprofit Search Element - This free search element is available for non-profit groups (such as charities, schools, and governments), and is similar to the Standard Search Element but does not have advertising.
  • JSON API - This API costs $5 per thousand queries, allows programmatic access, and does not have advertising or Google branding. However, this API is limited to 10,000 queries per day.
Today, we are excited to add a fourth implementation option.
  • Site Restricted JSON API - This API is similar to the JSON API above, but there is no daily query cap for Custom Search Engines that search 10 sites or fewer.
Learn more about how to use the Site Restricted JSON API from the developer site, or learn more about the differences between these offerings to help select the implementation option that works best for you.

Improving our offering for Nonprofits and Schools

If you are a nonprofit or a school looking for high quality, customizable search experiences for your site, organization, or school, we are excited to announce that Custom Search Engine is now integrating with Google For Nonprofits,, and with Google For Education,, to offer Custom Search Engine for free without advertising. Learn how to sign up for these programs in our help center.

Refocusing and looking forward on Custom Search Engine

We have several important announcements that may affect your Custom Search Engine or may require you to make changes to your Custom Search Engine. Please read this post carefully.

Custom Search Engine (CSE) is a great way to build custom search experiences for your website visitors. The search space is evolving rapidly and we want to make sure that CSE continues to evolve to meet the needs of your users, whether they are visiting from desktop or mobile devices. In order for us to achieve this, we first need to clean up some older access points that cannot support the improvements we will be adding.

Beginning in April 2017, the following API access points, and some associated features, will no longer be available:

How to tell if you are using it
What to do instead
V1 API and AutoCSE
Look for the javascript
Move to the current API.
Look for an http request containing a ‘cref’ parameter
Use the CSE control panel to set your CSE configuration.
Webmasters that host annotation files on their website
Use the CSE control panel to input or upload your annotations.
Dynamically extracted links
An included or excluded site uses the “Dynamically extract links from this page” option
Use the CSE control panel to input or upload your annotations
Autocomplete Removals
Search Features → Autocomplete → Custom Autocompletions → excluded or excluded patterns
There will no longer be a way to exclude certain autocompletions.
Autocomplete Promotions
Search Features → Autocomplete → Custom Autocompletions → promotions
There will no longer be a way to show promotions inside autocompletions; however, normal promotions will continue to work.
Ads UI style customization
Look for custom Ad Styles in the AdSense frontend under My Ads → Search Ads → Settings
The Ads UI will now be updated to use the styling of organic search results, which can be updated in the Look and Feel tab of the CSE control panel
We recognize that making these changes may be inconvenient, but cleaning up these old interfaces will allow us to focus on many new and exciting improvements to CSE. We will be modernizing the look and feel of CSE for both desktop and mobile users, improving uptime and latency, and working on the quality of our search results and autocomplete. We look forward to delivering a better CSE experience for webmasters and your website visitors alike.

Create a search engine with types

We are happy to announce the integration of Google Custom Search with the standard. is a structured data markup schema including a shared markup schema vocabulary that is supported by major search providers. This integration enables you to create powerful and expressive topical search engines by simply specifying types in your Google Custom Search Engine definition. 

How would you go about using this new feature? Say you are the webmaster of a site about movies. You might want to create a movie search engine that can search for pages about movies either from your website, your affiliated websites or from the millions of sites that use Achieving this functionality is now only a click away thanks to the integration of Google Custom Search with All you have to do is add the schema type “Movie” to your Custom Search Engine definition, as shown below, and you’re done! Users of your movie search engine will then only see result pages that have the “Movie” schema annotation.

You can even refine search engines with other advanced search features. For example, you might make an engine for pages that describe, with a country restriction of "France", or a language restriction of "French".

Bootstrapping your CSEs from keywords

Custom Search provides upto 5000 URL patterns to define a “slice” of the web to search over. However, if you’re creating a Custom Search Engine on a topic, such as “global warming”, finding more than a few good sites for a topic can be hard. We recently launched suggested sites to help suggest more sites for your search engine similar to  your included sites.

Today, we’re introducing another tool that is hopefully intuitive as well as interesting : You can discover hundreds of sites to include in your CSE starting just with keywords! For example, for a CSE on “global warming”, adding keywords like [pollution], [global warming] and [greenhouse effect] can lead you to discover global warming related sites within minutes.

This tool attempts to combine Google’s knowledge with the topic expertise you have - Google suggests sites, but you can control the topic expansion, and guide the tool towards your topic in a fine grained way.

The tool is accessible off of the New Search Engine page on the Custom Search control panel.  Give the tool a whirl, see more details on how the tool works in our documentation, and let us know what you think on the product forum.

Suggested sites for CSEs

Have a CSE to search over your favorite topic (e.g. cars)? Here is a new feature to help you expand your CSE’s definition. This feature recommends more url patterns relevant to the ones you already have in your search engine. We also provide a set of sample pages for each of the recommended patterns.

You can find more documentation here.

A new look for Custom Search control panel

We’re excited to announce a new, modern design for the control panel in keeping with prior user experience changes to Custom Search. You’ll also find a more intuitive layout to the various controls and configuration options. While configuring a Custom Search Engine, you can immediately view and test your work within the control panel.  

We hope you enjoy the new look!
