How to Use Google Trends for SEO?

TL;DR

Google Trends helps SEO teams compare relative search interest, regions, and related queries without a paid volume tool. Search Central frames Explore and Trending now as the core surfaces, with 2025-26 updates adding an API alpha and Gemini-assisted comparisons.

  • Why it matters: Relative interest reveals seasonality and breakouts before you commit calendar or optimization time.
  • How it works: Explore compares custom terms and topics; Trending now surfaces rising queries with related news context.
  • By the numbers: The July 2025 Trends API alpha offers consistently scaled interest back 1800 days (~5 years).
  • What's next: The January 2026 Explore refresh uses Gemini to auto-compare related terms and suggest follow-up prompts.
  • Reality check: Website scores rescale 0-100 per request, so treat Trends scores as directional interest rather than absolute volume.

When it comes to improving your SEO, some free tools are worth the effort, including Google Trends. This program will analyze a sample of web searches done for a keyword or phrase and tell you how popular it was in the last 90 days

One thing marketers get wrong with SEO is that trends are fluid. The keyword you used even six months ago may no longer be the one to offer the best results. That’s why doing regular content audits and updates is essential. 

Google Trends is a powerful tool to keep in your toolbox, and it’s free. The trick is to know how to use it for SEO. This article will provide tips on getting the most out of your SEO with a Google Trends search.

Google Trends is a tool Google offers to show you what’s hot and what’s not in searches both on the engine and YouTube. You enter a keyword you want to use in your content, and Trends allows you to see how it is trending. 

For example, if you were to enter the keyword “coffee drinks,” you would see it is pretty much always trending. It is a little more prevalent in some states, such as Hawaii, Washington, and Kansas. It is a bit less popular in places like New York.

What about “specialty coffee flavors”? That might seem like a good choice, but Trends tells you it gets almost no searches. If you enter “Mocha coffee bean,” it has had a surge just recently.  

Google Trends allows you to fine-tune your SEO to ensure you drive the right kind of traffic to your web pages. 

You don’t need a Masterclass to understand Google trends. Here are some facts that will help you define how it works:

  • It does not show search volume. It provides a scale from 0 to 100 that shows a search term’s relevance. Zero is no relevance, and 100 is the highest.
  • Trends pull data from five places to create the scale rating: web searches, image searches, Google News, Google Shopping, and YouTube. You can narrow the search down to just one of these using the dropdown menu at the top of the results page. 
  • You can also narrow down the location, time frame, and categories using a dropdown menu. Categories refer to industries such as entertainment or beauty. 

How to Use Google Trends

Simply type the keyword you are researching into the search bar and hit enter. Google Trends will show you search results in two ways.

First, you see a graph of the scale rating from 0 to 100. It is easy to see if the keyword is blowing up right now. Hover over the lines on the graph to determine the specific rating for a particular date. 

If you scroll down, it will show you how the keyword faired in each state. Hover over the states to get specific information. 

Most people stop at the visuals, but it’s worth digging around for context. Quite often, you’ll notice a spike on a graph and immediately wonder what caused it—maybe a viral tweet, maybe a new product drop, or sometimes, just random internet chaos. Either way, don’t be afraid to check the dates of relevant industry news or events. That curiosity tends to pay off when you’re crafting content that doesn’t feel out of touch or stale. In a way, Google Trends works best when you treat it less like a crystal ball and more like a flashlight—you see where things are moving, even if you can’t predict exactly what’s next.

One little detail I like is comparing multiple keywords side by side, especially if you’re battling indecision about phrasing. For instance, “iced coffee recipes” versus “cold brew ideas”—they might sound similar, but you can watch how their popularity crosses or diverges over a year. This is handy for anyone managing seasonal content or working in a niche that gets a lot of buzz all at once (think: fitness trends every January). There’s something kind of satisfying about seeing that line creep upwards, even if it’s just a small surge; it gives you a nudge in the right direction without overthinking it.

Scroll down further to find related topics and queries and their ratings. This gives you an idea of what keywords you might pair with your search or even replace them to get better results. 

There is a lot to unpack in a Google Trends search. It takes you beyond just trending keywords. You’ll want to spend some time and figure out how it can help you develop your SEO strategy. Here are some of the best uses for Google Trends. 

Topic Ideation

The most potent section on Google Trends’s search page is the list of related topics and queries. 

Let’s go back to the search for “coffee drinks.” The related topics show:

  • Flat white – drink
  • Batida – Cocktail
  • Constipation – Syndrome
  • Sugar-free drinks – Drink
  • Rum – Liquor

These are all listed as “Breakout.” That means the search term grew by 5,000%, according to Google News Initiative. You can use that information for topic ideation.

For instance, a flat white drink is a popular coffee option in specialty shops. It is a blend of micro-foamed milk over a shot of espresso. If your brand sells gourmet coffee to consumers or coffee shops, this could be a blog topic that moves you to the top of the search ratings. 

If you click on Flat white – Drink, it will search that term for you. The related topics sections show that the flat white recipe is up 70%. You could add that to your product page or even labels. 

Related Keywords

You can add one or two of those breakout terms to your content to move that page up in the search ratings. Be careful relying too heavily on breakout terms, though. They can be fads and unstable. Flat white might start to drop in a week. 

Look for consistency. Use the time selections option to understand how stable the trend might be.

Break Big Topics Down

Google Trends is a practical tool to use when you need to whittle down a large topic. Creating a blog on just coffee drinks isn’t going to help your SEO much.

You can use Trends to find out what people are interested in regarding that large topic. That takes you from one blog to several or even a series.

Use the Category Option

Using the category option gives you even more topic ideas. It can also help you target your audience. If you switch to the “health” category in the coffee drinks search, the related topics and queries change to best suit that industry. 

Using the various dropdown menus can add context to your searches. That will allow you to understand their relevance better. Remember that every other brand gets this data for that keyword search. Using the dropdown menus is how you make it unique for your needs. 

Google Trends is a tool that can help you improve your SEO and costs you nothing but time. It shouldn’t be the only tool you use, though. You’ll need quality content and to practice good overall SEO to see results. 

Frequently Asked Questions

Is Google Trends useful for SEO keyword decisions?

Yes, when you need relative interest, seasonality, geography, and related queries rather than exact monthly volume. Use Explore to compare candidate terms and topics, then check related topics and rising queries before drafting. Trending now is better for recent breakouts with news context. Keep Explore for controlled comparisons and Trending now for reactive monitoring.

What is the difference between Explore and Trending now?

Google Search Central describes two main tools: Explore for custom terms and topics, regional interest, and related topics over time, and Trending now for what is rising recently, with approximate Search volume signals, timelines, and related news. SEO planning usually starts in Explore for controlled comparisons, then uses Trending now for reactive topic monitoring. Keep filters for location, date, category, and property consistent when you compare terms.

How does the Google Trends API change SEO research workflows?

The Google Trends API alpha announced 24 July 2025 provides consistently scaled search-interest data across requests. Google says the API covers a rolling 1800-day (~5-year) window with daily, weekly, monthly, and yearly aggregations plus region and subregion breakdowns. That helps marketers join Trends pulls over time without the website's per-request 0-100 rescaling.

What are the main limitations of Google Trends for SEO?

On the Trends website, each request is scaled from 0 to 100, so values are relative interest rather than absolute searches. Google's API post notes those website scores are not absolute counts and are hard to merge across separate requests. Breakout labels can also mark short-lived spikes, so validate stability across longer date ranges before rebuilding a content cluster. Use Trends to prioritize and time topics, then confirm demand with other SEO data sources.
