How to Find Keyword Search Volume: Free vs Paid Tools

Search volume is an estimate of how many times a keyword is searched on average per month in the country and period you choose. The most reliable free way to find it is Keyword Planner inside Google Ads. Google Trends shows how interest changes over time, and Search Console shows the queries your own site actually appears for. Paid SEO tools estimate these figures with their own models and are most useful for comparison.

What does search volume show, and what doesn't it?

By Google's definition, "average monthly searches" in Keyword Planner shows how often a keyword and its close variants were searched on average, based on the date range, location and search network settings you choose. By default it is the average of the last 12 months. For a seasonal product, that yearly average can hide what happens in the peak month.

What volume does not show matters just as much:

• It is not the traffic you will get. Even in first position, some searchers do not click; ads, maps and AI summaries share the clicks.
• It does not tell you intent. "Shoes" is searched a lot, but what the searcher wants is unclear. "Waterproof hiking shoes size 9" is searched rarely, but the intent is clear.
• It is not an exact counter. Depending on your account, Keyword Planner may show a range instead of an exact number, and the numbers paid tools give are estimates too.

How do you check volume in Google Keyword Planner?

Keyword Planner is free but needs a Google Ads account. According to Google's help page, to access basic features such as "discover new keywords", you need to complete account setup by entering billing information.

1. In Google Ads, open Keyword Planner from the Tools menu (menu names can change with interface updates).
2. If you already have a list of keywords, use the search volume and forecasts option; if not, use the option to discover new keywords.
3. Set the location to your target country (or region) and the language to your target language.
4. Change the date range to check seasonality, and always look at the monthly breakdown chart.
5. Download the results and move them into your own sheet.

Watch two points. First, historical statistics are shown for exact match only; you see the same volume whether you enter the keyword as broad or phrase match. Second, "forecasts" and "historical metrics" are different things. Forecasts take bids, budget and seasonality into account and are based on the last 7 to 10 days of data; for content planning, historical metrics are more meaningful.

What is Google Trends useful for?

Trends does not give absolute search counts. According to Google, each data point is divided by the total searches in its region and time period, and the result is scaled from 0 to 100. A value of 100 marks the highest relative interest in the period you chose. Terms with very low volume show as 0, and the data is calculated from a sample.

So use Trends for shape, not numbers:

• To see in which months a keyword rises and falls.
• To compare which of two phrasings people prefer.
• To understand in which regions interest is concentrated.

A practical rule: take the size from Keyword Planner and the timing from Trends.

Why is Search Console the most accurate source for your own site?

Keyword Planner and paid tools estimate the market; Search Console measures how many times your own site was actually shown and clicked in Google. The Performance report gives clicks, impressions, click-through rate and average position, and lists them by query.

There are two opportunities here. First, queries you never targeted but receive impressions for; they show which words demand really arrives through. Second, queries with many impressions that sit on page two; these are the fastest wins, because you can capture them by strengthening an existing page.

A data source has also been added for AI search: the Generative AI performance report, available on all sites since 31 August 2026, shows how many times your pages appeared in AI Overviews and AI Mode, broken down by page, country and device. The report is page-based rather than query-based, but it shows which of your content is linked in AI answers.

When do you need paid tools?

The real value of tools such as Ahrefs and Semrush is not the volume of a single keyword but scale: pulling hundreds of variations around a topic in one go, filtering by difficulty score and seeing which keywords bring competitors their traffic. Because these tools estimate volume with their own data sources and models, they can give different numbers for the same keyword.

The right way to use them: do not treat the number in a paid tool as absolute truth; use it to rank keywords against each other. When deciding, cross-check with Keyword Planner and Search Console. If you are working with one topic and a few dozen keywords, free tools are enough.

Are low-volume keywords worthless?

No. Especially in B2B and local services, a phrase searched 20 to 30 times a month can bring more customers than a generic keyword searched thousands of times, if it carries the right intent. Phrases such as "Canias ERP consulting" or "dental clinic appointment in Kadıköy" are of this kind.

Watch out for word variants as well. Forms such as "price", "prices" and "how much does it cost" may be merged in Keyword Planner as close variants, but the search results page can differ. In languages with rich word endings, such as Turkish, this effect is even stronger. Capture the real phrasing from Google's autocomplete suggestions and your Search Console queries.

How do you turn volume data into a content plan?

Collect your keywords in one sheet: keyword, estimated monthly volume, seasonality note, intent (informational, comparison, purchase) and the page it belongs to. Then work in this order:

1. Group keywords with the same intent on one page; do not open a separate page for every variant.
2. Start with the group closest to your business and with the clearest intent.
3. Prioritize queries that have impressions in Search Console but a weak position.
4. For seasonal keywords, publish the page at least a few weeks before the peak.

Common mistakes

• Writing only for the highest volume: for generic keywords, the first page is full of large sites, and a new site risks staying invisible for months.
• Setting the location wrong: if Keyword Planner is left on "all locations", the volume of a keyword can be mixed with searches from other countries.
• Ignoring seasonality: looking at the yearly average and publishing in December for a keyword that peaks in November.
• Checking once and stopping: demand changes. Update your keyword sheet with Search Console data every three months.

Summary

Take the size of demand from Keyword Planner, the timing from Google Trends and the reality of your own site from Search Console. Use paid tools for scale and competitor analysis, and read their numbers as estimates. When choosing keywords, look at intent before volume.
