Every day, users around the world depend on Google to find answers. But there is a unique group of people (researchers, journalists, and developers) who are interested in discovering what the world is searching for online.

And at the recently held Search Central Live APAC 2025, Google had a surprise in store for these attendees. 

The company announced the alpha preview of its first official Trends API, which will help users interact with search data more simply and quickly. 

This allows journalists, researchers, marketers, and developers to access Google Trends data directly through code without relying on the manual web interface. This can provide several advantages. 

Google Invites Applications for API

John Mueller, a Senior Search Analyst at Google, encouraged people to test the Trends API in a LinkedIn post. He explained that;

“If you’re a researcher looking to use Google Trends for regular analyses, check out the alpha preview of the first API for Google Trends,” he wrote, adding that Google wants to ensure that the API is both valuable and sustainable for long-term use. 

“There’s still a lot of work to do, and we want to make sure it’s useful for reasonable usage. If you’d like to bring your input, try out a new API, and help shape the final API, feel free to sign up for the (very limited) early tests in a few weeks/months.”  

Meanwhile, Google Search Central also announced the same on LinkedIn and invited applications, saying that the new API will “help Researchers, Journalists, and Developers to understand Search behaviors and patterns.”

What is Google Trends?

Before we go further, let’s quickly look at what exactly Google Trends is. It is a tool used worldwide to track what people are searching for online. 

This free-to-use tool is a part of many journalists, researchers, and developers’ daily workflows. 

Since its inception, Google Trends has provided information to users through a web-based interface. And although this has been sufficient for many casual users seeking a quick comparison, the situation has been different for researchers or analysts who require consistent, large-scale data over long periods.

And to solve this problem, Google is now here with its new Trends API.

About Google’s New Trends API

Google’s Trends API allows users to request specific search trend data directly from Google using code, without the need to manually browse the website.

In a blog post, Google explained that the API offers a five-year rolling window of data, with results accessible up to approximately 48 hours ago. This can be useful for long-term analysis, tracking evolving stories, seasonal trends, and major global events. 

Therefore, the introduction of the Trends API represents a significant upgrade in how Google Trends can be utilized. For journalists covering viral moments, researchers tracking public interest, or developers creating tools, the API could streamline workflows and enhance insights.

Though it’s still in alpha and access remains limited, the goal is clear: Google is updating how it provides one of its most valuable public datasets—something many professionals have long requested.

What does the API offer currently?

Currently, the Google Trends API helps track how interest in specific search terms or topics has changed over time. Users can break down that interest by:

• Time: Weekly, monthly, or yearly intervals
• Geography: Countries, regions, or even cities

This makes it easier to see when something was popular and where it was searched the most. Additionally, the results are consistently scaled, which is a key difference from what you might see on the Trends website. 

Trends API vs Google Trends website

On the Google Trends website, search interest scores are scaled depending on what you search and how you filter it. So, the scores can vary between searches. 

But with the Trends API, this scaling method remains consistent across all your requests. That means the numbers are more reliable and easier to compare, which is helpful if you do serious analysis. Google explained in its blog post:

“On the Trends website, the results are scaled from 0 to 100 every time you request data. The API uses a different method for scaling, which is consistent across requests, and lets you join, compare, and merge data from multiple requests. However, while the API returns consistently scaled data, the numbers don’t reflect absolute numbers; they reflect search interest.”

It is worth noting that since the API is still in its early stages, Google is focusing on making it stable and easy to understand, rather than including every possible feature or dataset immediately. 

This limited scope appears intentional because it allows early testers to give feedback that helps shape future versions.

How to Use Trends API?

As mentioned before, the Trends API isn’t fully developed yet and is currently in its Alpha stage. A small group of early users are testing it out and will play a key role in shaping its future development. 

You can sign up for the early access program if you’re a researcher, developer, or journalist who frequently works with Trends data. All you need to do is register yourself using the official form.

Participation will be limited during this phase, and access won’t be granted immediately. However, those selected will help shape what the final product becomes. 

Google also mentioned in its blog post that even if you don’t get chosen to test the product now, there’s still hope. 

“If you’re not in the first batch of developers, don’t worry, we’ll ramp up access in the coming months.” – The blog post read. 

What To Expect If You Are Selected

Once you have registered and gained access to the API, you’ll likely receive technical documentation, usage limits, and possibly community channels for feedback.

Future versions might include more query options, support for additional data slices, or integration with other developer tools. But for now, Google focuses on making the core functionality stable, useful, and respectful of data use norms.

It’s also important to understand what the Trends API does not aim to do. This isn’t about providing users access to raw or real-time search logs. Instead, the API offers aggregated, anonymized data intended for long-term, high-level analysis—similar to the public version of Google Trends, but now easier to handle at scale.

The five-year rolling window is meant to help users observe shifts in public interest over time, not monitor individual behavior. 

By maintaining privacy and aggregation, Google states it stays true to the core principles of Trends. 

The API also isn’t intended for commercial forecasting or instant trend-spotting; it’s geared more toward structured research, experimentation, and transparency—exactly the kind of use cases where stable, clean datasets matter most.

Final Takeaway

Google is making it easier for professionals like journalists, researchers, and developers to access and analyze what people are searching for online. 

The Trends API, currently in its Alpha stage, is designed for those who want to perform serious analysis and need reliable information. It allows users to access Google Trends data directly through code.

To try out the Trends API in its Alpha stage, you need to register by filling out a Google form. Access to this API will be by invitation only, but in the future, Google might invite more users as well. The scope is still limited since the API is in its early days, but the direction is clear.
