Build a Keyword List With Three Free Google Tools

Updated 5 November 2026 · Standard formula, shown below

Build a useful keyword list by combining Google Keyword Planner, Google Search Console, and Google Trends. Together, these free Google tools help you discover possible search terms, find queries already bringing visitors to your site, and judge whether interest is steady or seasonal.

What Each Tool Adds to a Keyword List

No single tool gives a complete picture. Keyword Planner is designed for keyword research in Google Ads; Search Console reports how a verified website performs in Google Search; Trends helps compare interest over time and across locations. Used together, they provide complementary evidence rather than a guaranteed ranking plan.

Google Keyword Planner: generates keyword ideas and provides estimates such as average monthly searches and competition for ads.
Google Search Console: shows queries associated with your site’s impressions and clicks, along with metrics such as click-through rate and average position.
Google Trends: compares relative search interest across terms, regions, and time periods; it does not report exact search counts.

All three are Google tools and can be used without paying for the tools themselves. Keyword Planner is part of Google Ads and may prompt you to set up an account or campaign. Search Console requires access to a website property, so it is most useful if you manage a site.

Start With a Clear Topic and Search Intent

Before opening a tool, define the subject and the audience’s likely goal. A list built around a real need is more actionable than a long collection of loosely related phrases. For example, a small business selling houseplants could begin with “indoor plants,” then consider whether searchers want care instructions, plant recommendations, or a place to buy.

Write down a few seed terms and group them by the job a searcher wants to complete. Common intent categories include learning, comparing options, finding a specific site, and taking an action such as contacting a provider. These labels are useful editorial guides, not official Google classifications.

Informational: “how often to water a spider plant”
Comparison: “low-light plants vs. shade plants”
Commercial research: “best indoor plants for apartments”
Action-oriented: “buy pothos plant”

The same broad topic can contain several distinct needs. A page about watering advice may not satisfy someone ready to buy a plant, even if both searches mention the same species.

Use Keyword Planner to Expand Seed Ideas

In Keyword Planner, choose the option to discover new keywords and enter seed phrases, a website, or both when the interface offers those choices. Set the location and language to match the audience you want to reach. Review the suggestions and export or copy relevant terms into a working spreadsheet.

Pay attention to relevance first, then use the available estimates as supporting information. Average monthly searches are estimates for a selected location and period, often displayed in ranges depending on account access and settings. Advertising competition describes competition among advertisers; it is not a direct measure of how difficult it is to rank organically in unpaid search results.

For the plant example, Planner might suggest related phrases such as “indoor plant care,” “plants for low light,” or “easy houseplants.” Keep only terms that fit the site and its audience. A large search estimate does not make an irrelevant keyword useful.

Find Real Queries in Search Console

If your site is verified in Search Console, open the Search results performance report and examine its queries. Filter by a relevant page, country, device, or date range if those controls are available for your property. Export the report when you want to sort and annotate the data outside the interface.

Queries with impressions but few clicks can reveal a mismatch between what people expect and how a result appears, but they do not prove that a title or description is the only issue. Check the page’s relevance, the search results around the query, and whether the page is visible at a position likely to receive clicks. A query with few impressions may simply have limited demand, or the page may not yet be prominent enough to appear often.

Search Console reports performance for your own site, not every search made on Google. Its query data is therefore a valuable source of first-party evidence, but it is not a complete keyword database or a forecast of future traffic.

Compare Timing and Interest With Google Trends

Enter a candidate phrase in Google Trends and set a suitable region and time range. Compare related terms when you are unsure which wording people use, and inspect regional patterns if your content serves a particular area. The chart is an index of relative interest, not an absolute count of searches; a peak does not tell you how many people searched.

Trends can help distinguish a lasting topic from a seasonal one. For example, interest in a phrase may rise during a particular season, while another term stays more consistent. Use that pattern to inform timing and content updates, but avoid treating a short-lived spike as proof that demand will persist.

Related queries and topics can suggest additional angles. Check them against the page’s purpose and the other tools rather than adding every rising term automatically. Trends comparisons can also be affected by spelling, wording, region, and the selected time period.

Turn the Research Into a Practical List

Put the findings into a spreadsheet with columns such as keyword, intent, topic group, source, location, date checked, Planner estimate, Search Console clicks and impressions, Trends observation, and target page. Recording the source and date matters because estimates and interest patterns depend on settings and can change.

Remove phrases unrelated to your subject, audience, or offer.
Group close variants and queries that can be answered by the same page.
Separate distinct intents when they need different pages or formats.
Choose a primary phrase for each page and retain useful supporting terms.
Prioritize topics using relevance, available evidence, and your ability to provide a genuinely useful answer.

For instance, “how often to water a spider plant” and “spider plant watering schedule” may fit one practical care guide. “Buy spider plant” reflects a different task and may belong on a product or category page. Keyword lists should guide useful page planning, not encourage repeating phrases unnaturally. Google does not require a fixed keyword density, and inserting every variant can make copy harder to read.

Common Misreadings and Limitations

Tool figures are not promises. Keyword Planner’s search estimates are not guaranteed organic visits; Search Console’s historical performance is not a traffic forecast; and Trends’ indexed values are not exact volumes. Different locations, dates, devices, and query groupings can change what you see.

Also, a keyword list cannot determine whether a page will rank. Search results depend on many factors, including the usefulness and relevance of a page and the broader search context. Use the tools to form and refine ideas, then inspect actual search results and write for the reader’s need. Recheck important terms periodically, especially for seasonal subjects or changing products and services.

Frequently Asked Questions

Are Google Keyword Planner, Search Console, and Trends free?
They can be used without paying for the tools. Keyword Planner is accessed through Google Ads and may require account setup; Search Console requires a site you can verify or manage. Account and access requirements can vary by tool.

Which Google tool is best for finding new keywords?
Keyword Planner is the most direct of these three for generating keyword ideas. Trends can reveal related terms and changes in interest, while Search Console is better for queries already associated with your site.

Does Keyword Planner show organic keyword difficulty?
No. Its competition metric relates to Google Ads advertisers, not a definitive measure of organic ranking difficulty. Assess organic results separately by reviewing the pages that currently appear and how well they meet the searcher’s need.

Can I use these tools without a website?
Keyword Planner and Trends can help with research without a site of your own, subject to their account or access requirements. Search Console is for measuring a website property you can access.

How many keywords should one page target?
There is no fixed ideal number. Focus a page on one clear subject and include closely related terms naturally when they help answer the same need. Split topics when the intent or useful answer is substantially different.
