How to Use Google Trends for SEO and Content Planning

Google Trends is free, and most people use it for about five minutes. Used properly, it helps you time content, choose between competing keywords, and spot demand before it shows up in paid tools. It also has real limits, which most guides skip.

What Google Trends Actually Shows

Google Trends shows relative search interest over time, on an index from 0 to 100, where 100 is the peak popularity for that term in the selected region and period. It does not show absolute search volume. A value of 50 means half the peak interest, not 50 searches.

That distinction shapes everything below: Trends is excellent for comparing and timing, and poor for sizing.

7 Practical Ways to Use It for SEO

  1. Compare keyword variations. Enter up to five terms to see which phrasing people use more. This helps choose between “search engine optimisation” and “SEO”, or between two service names, for page titles.
  2. Spot seasonality. Set the time range to five years and look for repeating peaks. Plan and publish content ahead of the peak so it’s indexed in time. For example, Australian financial-year content would be expected to build toward the end of June; confirm with the tool for your own topic.
  3. Check demand by Australian state. Filter to Australia, then review the regional breakdown. Useful for deciding where to focus local content or advertising.
  4. Find rising topics. In “Related queries”, switch from “Top” to “Rising” to see queries growing fastest. These are early signals worth considering for new content.
  5. Choose the right search type. Switch between Web Search, Image, News, Google Shopping and YouTube Search to see where interest actually sits for your topic.
  6. Validate a content idea before investing. If interest in a topic is steadily falling, a big content investment may not pay off. If it’s stable or growing, it’s safer.
  7. Plan a content calendar. Combine seasonal peaks with your publishing schedule so major pieces land a few weeks before demand rises.

Step-by-Step: A Quick Workflow

  1. Go to trends.google.com and set the location to Australia
  2. Enter your main keyword, then add up to four alternatives to compare
  3. Set the time range to 5 years (or 12 months for fast-moving topics)
  4. Note peaks, troughs and the overall direction
  5. Check “Related queries” and “Related topics”, using “Rising” for emerging ideas
  6. Take promising terms into a keyword tool to get actual volumes and difficulty
  7. Record findings in your content plan

Limitations to Keep in Mind

  • No absolute volumes. Always confirm with a keyword tool before deciding
  • Low-volume terms may show no data. Niche local or B2B phrases often don’t register
  • Data is sampled and normalised, so numbers can vary slightly between checks
  • Comparisons only work within the same chart. You can’t compare an index value from one chart to another
  • It reflects Google search behaviour, not AI-assistant or social search

Using Google Trends Alongside Other Tools

Trends tells you the shape of demand; a keyword tool tells you the size and competitiveness; Search Console tells you what your own site already earns. Use all three, in that order, when planning content.

Frequently Asked Questions

Is Google Trends free?

Yes, it’s free to use.

Does Google Trends show search volume?

No. It shows relative interest on a 0-100 scale, not the number of searches.

Is Google Trends good for keyword research?

It’s good for comparison, seasonality and spotting rising topics, but you need a separate keyword tool for volume and difficulty. See our keyword research guide.

Can I use Google Trends for local Australian SEO?

Yes. You can filter by Australia and view state-level interest, though small local terms may not have enough data to display.

Why does Google Trends say “Not enough data”?

The search term doesn’t have enough volume for Google to show a chart. Try a broader term or a longer time range.
