Keyword tools tell you roughly how many people search for something. Google Trends tells you something different and often more useful: when they search, where they search, and whether interest is growing or fading. For planning content, timing campaigns and choosing between two phrasings, that context can matter more than a monthly average.
Trends is free, it is based on Google's own search data, and it takes seconds to use. It is also one of the most misread tools in marketing, because its numbers are not search volumes. A score of 100 does not mean 100 searches, and a line that doubles does not necessarily mean demand doubled in absolute terms.
In this guide you will learn how Google Trends data works, how to read it correctly, and seven practical ways to use it for SEO and content planning in 2026.
Key Takeaways
- Google Trends shows relative search interest on a 0–100 scale, based on a sample of searches, not absolute volume.
- It is ideal for seasonality, comparing phrasings, spotting rising topics and checking regional differences.
- Use "topics" for broad concepts across languages and spellings, and "search terms" for exact phrasing.
- "Rising" related queries and "Breakout" labels highlight fast-growing searches worth investigating early.
- Combine Trends with a volume tool such as Keyword Planner before deciding what to create.
How Google Trends Data Works
Google's Trends help centre explains the method clearly. Trends uses a sample of Google searches. Each data point is divided by the total searches in that geography and time range, so you see relative popularity rather than raw counts. The results are then scaled from 0 to 100, where 100 represents peak interest within the chart you are looking at.
Several adjustments affect what you see:
- Low-volume terms show as zero. Trends only shows data for popular terms, so niche queries may appear empty even though people search for them.
- Repeat searches are removed. Multiple searches by the same person in a short period are not all counted.
- Special characters are filtered. Queries with apostrophes and similar characters are excluded.
- Different regions are not directly comparable in volume. Two regions with the same interest score may have very different total searches.
“Trends eliminates repeated searches from the same person over a short period of time.”

Google Trends vs Keyword Tools
| Question | Google Trends | Keyword Planner or SEO tools |
|---|---|---|
| How many searches per month? | No: relative interest only | Yes: estimated averages or ranges |
| When does interest peak each year? | Yes, clearly visible | Partly, via monthly breakdowns |
| Is a topic growing right now? | Yes, including recent days | Usually with a delay |
| Which of two phrasings is more popular? | Yes, side by side on one scale | Yes, but estimates may group variants |
| Where is interest highest? | Yes, by country, region and sometimes city | Limited to the location you target |
| How hard is it to rank? | No | Third-party tools estimate difficulty |
The two types of tool answer different questions, so use them together. Our guide to search volume explains how to interpret volume estimates, and our comparison of keyword research tools shows where Trends fits in a full stack.
Search Terms vs Topics
When you type into Trends, you can often choose between a search term and a topic. Google defines topics as groups of terms that share the same concept in any language. A term matches your exact words in the chosen language. Use topics for overall demand (for example a brand or a product category) and search terms when you need to compare specific phrasings, such as "trainers" versus "sneakers".
In the current Explore experience you can compare several groups of terms at once, and each group can contain multiple terms. Comparing on the same chart is the only reliable way to compare scores, because every chart is scaled to its own peak.
7 Ways to Use Google Trends for SEO
1. Map seasonality before you publish
Set the time range to five years and look for repeating peaks. Publish or refresh content several weeks before the annual rise so pages have time to be crawled and gain visibility. This feeds directly into your content calendar and seasonal marketing plans.
2. Choose the right phrasing
Compare variants your customers might use. The more popular phrasing usually belongs in titles and headings, while variants can appear naturally in the body.
3. Separate fads from lasting trends
A sharp spike that collapses suggests a news-driven fad. A steady climb over several years suggests sustained demand worth building evergreen content around.
4. Find rising queries early
The related queries panel shows "Top" queries (most frequently searched alongside your term) and "Rising" queries (those with the biggest growth in the selected period).
“If you see "Breakout" instead of a percentage, it means that the search term grew by more than 5000%.”

Breakout queries often have little or no volume in keyword tools yet. That is exactly when publishing early pays off, as we explain in our post on zero-volume keywords.
5. Prioritise regions and locations
The interest-by-region view shows where a topic is relatively most popular. Businesses serving several areas can use it to decide which location pages or campaigns to build first, then confirm volumes with Google Keyword Planner.
6. Plan video content with YouTube Search data
Switch the search type from Web Search to YouTube Search to see how interest differs on YouTube. This is useful when deciding which topics deserve a video. See our guide to YouTube SEO.
7. Monitor brand and competitor interest
Compare your brand topic with competitors over time. It will not tell you exact search volumes, but it shows whether awareness campaigns are moving the needle relative to the market.
Step-by-Step: A Quick Trends Check for Any Keyword
- Open Google Trends and enter your main keyword. Choose the topic or term option deliberately.
- Set the country you target and a five-year time range.
- Add two or three alternative phrasings to compare on the same chart.
- Note the seasonal pattern and the long-term direction (rising, flat or falling).
- Scroll to related queries and switch between Top and Rising to collect new ideas.
- Check interest by region to see where demand is concentrated.
- Take the shortlist to a volume tool and the live results page before committing to content.
Reading Trends Charts Correctly
| What you see | What it means | What it does not mean |
|---|---|---|
| A score of 100 | The peak point of interest within this chart | 100 searches, or the same volume as 100 on another chart |
| A score of 0 | Not enough data for this term, place and time | Nobody searched |
| A line falling over five years | A shrinking share of all searches | Necessarily fewer absolute searches, as total search activity changes too |
| Same score in two regions | Similar relative popularity | Similar total search volume |
Common Mistakes With Google Trends
- Treating scores as search volumes. They are relative indexes, scaled per chart.
- Comparing numbers across separate charts. Each chart is scaled to its own peak; compare inside one chart.
- Using short time ranges for strategy. A seven-day view shows news spikes, not seasonal patterns.
- Ignoring the term versus topic choice. The results can differ a lot.
- Chasing every breakout. Only act on rising topics that fit your audience and expertise.
- Over-reading small samples. For niche terms, sampling can make lines jumpy; look at longer periods.
What About the Google Trends API?
In July 2025, Google announced an alpha version of a Google Trends API on the Search Central blog, giving a limited group of testers programmatic access to Trends data. For most businesses the web interface is all you need, but it is worth watching if you build dashboards or large-scale research workflows.

Frequently Asked Questions
Does Google Trends show search volume?
No. It shows relative interest on a 0–100 scale for the chart you are viewing. Use Keyword Planner or an SEO tool for volume estimates.
What does 100 mean in Google Trends?
It marks the peak popularity of the term within the selected time range and location on that chart. It is not a number of searches.
What is a Breakout in Google Trends?
Google says Breakout means the search term grew by more than 5000% in the selected period, shown instead of a percentage.
Why does my keyword show zero in Google Trends?
Trends only shows data for popular terms, so low-volume searches can appear as zero even if some people search for them.
Should I use topics or search terms?
Use topics to measure overall interest in a concept across spellings and languages, and search terms when comparing exact phrasings.
Put Timing on Your Side
Google Trends will not tell you how many people search, but it tells you when, where and whether interest is growing. Use it to time content, choose phrasing and spot rising topics, then validate with volume data and the live results page.
